@ 2:30 Bill The end customer & GM thanks you for your 20+ years of tireless service. It takes a special person to actually make an effort to solve problems & not just deny it till its out of warranty.
I understand that. I worked for McDonnell Douglas aircraft. We built our planes so well they would last 50 plus years which meant customer did not have to buy new as often. It screwed us in the end. Boeing built a 20 year plane at a good price and bought MDC.
It’s not even a bad coolant. Just gotta make sure when you change your coolant you put the exact same coolant back in the system. People run into issues when they change their coolant and add the green stuff and it mixes with the orange Dexcool that might still be in the engine block and that’s when it turns everything to sludge when the two coolants mix. Dexcool is pretty good at lasting a long time you shouldn’t need to change it unless you notice it’s looking dirty in anyway. When you go to buy Dexcool it usually says on the back made for GM vehicles and it should say Dexcool on it
Been buying chevy cars and trucks since 2000 and never had one issue with dexcool. I maintain my vehicle(s), theres no such thing as a lifetime fluid/1 year engine oil... I have a 2002 chevy malibu with the 3.1 and opened up the engine for other minor reasons. The oe plastic intake manifold gaskets were in perfect condition. Always used dexcool. Like he said, if it runs low and you never replace it, you will have issues. I change my coolant every 2-3 years and bleed the system. It's a 1 hour job people.
I had my factory installed GM original gaskets go out in year #5. I replaced them with the GM original REVISED gaskets. It is year #21 of ownership for me. The gaskets are still holding. I have never stopped using Prestone Dexcool, but I'm flushing the entire cooling system every 3 years. I also replace the thermostat and the radiator cap at every second coolant flush, so every 6 years. For a complete flush, I remove the thermostat and then flush the system with TAP WATER out of a garden hose (made my own adapters) until the system only holds tap water only. Then I remove half system capacity and refill with Dexcool concentrate. My recovered 3 year old Dexcool is always crystal clear. My cooling system has no deposits what so ever either. I have recently replaced the original radiator (the side tank cracked) and dissected it before discarding it. This almost 20 year old radiator was absolutely clean inside. No deposits what so ever. Also the 20 year old hoses were soft like new. Proof is in the pudding. Dexcool and tap water make a great coolant. I will continue to use this mix for the lifetime of the vehicle.

In most cases it's best NOT to create a script, but just create bullet points on the queue cards, so that what the presenters are saying is fresh and contemporary. Normally the presenters are experts on the subject, so just give them a little direction with bullet-points and let them riff. You'll get a much more natural and much less robotic presentation that way.
1:40 WHEN THE ANTIFREEZE GOT LOW in the cooling system, it was replaced by AIR. AIR COMBINED WITH ANTIFREEZE and formed an ACID. The acid attacked the black plastic carrier used in those OE style gaskets, then _____ . 1) 3:40. We also REPLACED the SILICONE RUBBER, WITH HNBR RUBBER. That's the stuff they use in batteries to separate the cells; so it's very resistant to acid. 2.) 3:49 We noticed on the OE parts, that technicians sometimes OVER-TIGHTENED the gaskets, sometimes causing failure. ❤️So we built in steel load limiters to solve that problem. 3.) 4:02 We saw another problem : .We designed an RTV DIVERSION CHANNEL on this gasket, so extra RTV was diverted AWAY from critical sealing areas. .
7 years late. Is the 5.3L vortec susceptible to this manifold gasket+dexcool+air=coolant acidic failure situation? I chased a leak for about 5 months and now worried about the long-term damage.
Does the coolant turn into a clear liquid when it turns into pure acid? Mi vehicle is currently dripping that from what looks like oil pan. Maybe the block cover it's called?
It's not OAT antifreeze. It's DEXKILL in particular. It does a lot more than just damage gaskets. It starts out as a liquid, and turns into a solid inside the engine, plugging up all the coolant passages and destroying the engine. I have torn down dozens of GM engines, some as new as 5 years old, that had the water jackets around the cylinders more than half plugged with a brown gooey waxy substance. It also plugs up the radiator, heater core, thermostat, coolant hoses, and even the water pump. If you have a GM vehicle, GET THIS STUFF OUT OF IT RIGHT NOW!!!. I recommend replacing it with Prestone OAT coolant. It has proven to be safe for engines, including aluminum engines, which can be damaged by the silicates that were used in older types of coolant designed for cast iron engines. It has nothing to do with the engine. DEXKILL will destroy any engine. In any vehicle, regardless of brand. And it is the ONLY so called "coolant" that has been known to cause this problem. Most auto manufacturers have their own brand of coolant these days, but not a single one of them have been known to cause problems, EXCEPT DEXKILL.
Great questions and answers, very informative. For these critic comments, looks like you paid no attention to what people where saying. Instead you write sentences of idiotic comments. Purpose of this video is to deliver information about a product and improvements and it is done professionally. Thank you MAHLE.
I bought a 1997 Chevy Suburban from the original owner. It has the 5.7 Vortec engine. How can I find out if the issue of the Dexcool antifreeze/ coolant had been repaired under the warranty?
I just ordered two sets of the premium gaskets, the steel was grey on one set and black on the other, both have the same part number. I went with Mahle brand because I know the design is well tested through R&D, even if most everything online says FelPro is the only gasket to use. The shop that built my engine cheeped out on everything and I'm sure the intake gaskets are no exception. The cooling system also leaked and your video concerns me because of air entering the cooling system.. Thanks for the honest opinion of Dex-Cool and the reason gasket failures are such a problem.
I just purchased an 05 Buick Century Limited. Was this car apart of the new gasket change? or would it still have the old gasket? It's got 153 k miles on it. Just opened the radiator cap to see some build up clinging to the sides of the opening. I plan on changing the coolant immediately, but would like to know what I"m up against here. This news is pretty devastating to a person who had no idea such an issue existed!!
If your radiator coolant inside your radiator is RED- thats dexcool NO GOOD! Flush out your cooling system inc. through the heater core, I would also replace thermostat and USE GREEN PRESTONE COOLANT! Dexcool was designed to eat away at your motors hoses and gaskets for FINANCIAL GAIN by GM! CLASS ACTION LAWSUITS ALMOST BANKRUPT GM!
I already changed the gaskets in my 1994 3.1L, so i know what he is talking about. The new improved ones have the steel. The original gaskets look so frail and cheap oh and i have never used DEX, i use the green stuff and no problems.
Mine smells like burning silicate ik cause I've burnt silicone before but it smells mote sweets so I think my car is burning cooling cause it's not a leak cause the level barely changes an my car hasn't over heated
@@JuvenalMena my car isn't it was bulletproofed an studded to fix the design of the 00-05 devilles i was just asking which brand, type stuff like that but ives figured that out its been 2 years 🤣🤣
Even with gasket changes multiple times, my Pontiac Montana van still went through all of its gaskets after just a few months. Never buying a GM product again.
We have a 2006 Buick Lacrosse 3.8l that still has Dexcool in it ( purchased last June ) . No pressurized coolant overflow tank . Would this engine have the " good " gaskets from the factory or " problematic " gaskets ? Shortly after we purchased it , I replaced the black plastic coolant elbows , radiator hoses and heater hoses . Refilled the cooling system with a new gallon of Dexcool . Will changing the coolant , this way , help the situation ? We also have a 2015 Chevy Sonic 1.8l , purchased new . At 2 years , I dropped the lower radiator hose and refilled it with new Dexcool . Will this type of servicing help this car ? ( it has a pressurized coolant overflow tank . ) Thanks , :-) Wyr God bless
This also happened to the Buicks with the 3800. i have several and they all failed with dexcool. I understand they fixed them and all that but I also understand I'm just not going to take the chance on it and I change them to green antifreeze . If I buy any GM product from the '90s to the mid-2000s I immediately flush out that all the coolant and put the green crap in. never had a problem like that. im looking at buying a 2000 LeSabre tomorrow 60k miles , guys great grandmas car, has the dexcool in it , that's being changed right after I drive it home. it's either that or I KNOW I'll have to change the gaskets (unless the dealership already did that) I love the engines of GM cars of the 90's and early 2000's but I am sick of doing intake gaskets on them ha ha .
Jasper Engines and Transmissions,the gasket sets come with the metal intake gaskets with their 350 and 4.3 vortec reman engines including the 3100 and 3400 engines.Every plastic intake gasket got thrown away.
So, this is a sales spiel for a particular gasket? I have a 2007 Hummer H2, which has had the same OEM anti-freeze for 12 years... I am about to do a radiator flush and fill with new anti-freeze, the Manual says, "50/50 mixture of clean, drinkable water and USE ONLY GM DEX-COOL(R) or Havoline DEX-COOL(R) coolant. The Hummer has been GREAT to me for 12 years, is there a concern about my refilling the radiator with DEXCOOL? Replacing gaskets on an engine that has no issues is not happening, so which is the safest coolant?
@@bobcat1 DEX-COOL is the best, most effective coolant for late model Chevy engines WHEN USED PROPERLY, which means you MUST bleed your radiator and engine water chambers to get all air/oxygen out of the system. It is excess oxygen in the system that cause the Dex-Cool to become acidic, caustic and damage OLD/LEGACY gaskets. Most NEWER gaskets handle Dex-Cool equally well, but the key is to BURP or BLEED the air out of the coolant system as best you can. My 2007 Hummer H2 has been running Dex-Cool in it's radiator since BIRTH/2007 and there are no signs of any gasket or leak issues whatsoever. Google BURP coolant for instructions on how to purge air from your system. I have NEVER in the 14 years I have owned my Hummer seen a coolant temp above 198, in fact... it always runs at 198 degrees. Since I wrote the original comment, my wife and I have driven 8400 miles, 22 states over a 2 month period between Sept. - Nov. 2020, every terrain type possible, Grand Tetons, Yellowstone, Custer Battlefield, Devil's Tower, Bear Tooth Pass (Scariest Road in America at night in dense fog. If you want to test brake pads, this is the road to do it.), Sturgis, Badlands, Crazy Horse Monument, Mount Rushmore, Memphis, Nashville, Biltmore Manson/Estate, Mayberry RFD/Mount Airy, NC, Ocean City, MD, Kitty Hawk, Cape Hatteras, NC, New Orleans, at the border in Texas during an ice storm, all places in between and a return to Las Vegas without any issues whatsoever. Never saw a coolant temp above 198 degrees.
Doesn't matter what coolant you use. That same shit happens to any cooling system that's not maintained like it should be. And the new gaskets still fail after 7 to 10 years.
Dex Cool is a special case, it's not uncommon for dexcrap to eat gaskets in 2-3 years tops, and even better is it moves the plastic sludge it creates into the water jackets, and water pumps. Just stick with the green stuff, and you won't have any problems. Any car with dexcool in it that I end up with gets a full flush out and swap to green. Oh, and dexcool will also eat any composite (plastic) intake manifolds it touches too, so even with new gaskets, you're still going to get leaks and need to buy a new plastic intake.
@@Mavairo Ford doesn't use Dexcool. Why do their intakes turn to shit over the years? That's just what happens with plastic. The gaskets failing early with Dexcool issue was addressed over 15 years ago. Hang that argument up already.
@@Carlitosway211 Why run Dexcool at all? It's pretty well documented, and it's no more protective than Prestone's green, and it's more expensive. Stop being a gm fanboy, it's a fuck up, pure and simple that costs more, and doesn't last any longer than green at best, and destroys older plastics at worst. btw Ford used a similar compound at one point which also ate plastic. And there's plenty of cars out there still on the older gasket design, swapped to green that haven't eaten away. I wonder why that is. It couldn't be because Dexcool sucks.
What everyone’s failing to say it’s not Dexcool that’s ruining the vehicle it’s people thinking Dexcool is bad and they change it out with the green stuff and when other coolant mix with Dexcool that’s when everything turns to sludge and eats the rubber hoses away and breaks water pumps gaskets.
My 1995 Impala SS had the green stuff from factory so I avoided dexcool issues. Most of the cars by 2003 had the issues worked out and no more problems
Im havin to do head gaskets on my 6.6 duramax . Im switching to the green stuff . Flushed the system real good . No more dex cool . Looks like dex cool eats aluminum also 😳
I will add to story. I got rid of my 2007 Pontiac grand prix 3.8 NA last yr because it I think had a coolant leak or air leak ??? That coolant at 205000 klms not miles now a ton of sludge brown and white mostly brown. I believe I had an intake leaked repaired by GM DEALER on 2000 Pontiac grand am that I am way back 2003 or later. So don't know how much of a drain it would have had and likely then they would have put dexcool in it also then. Few questions and concerns here. PLEASE tackle them in detail from these two messages thank
I've been a mechanic for 35 years on all makes and models. I own only GM at least 3 at a time and 7 right now. The coolant gets changed every 3 years in each one whether someone else thinks it needs it or not. Never any kind of gasket failure.
I had DexCool in my 96 GMC Z71 and believed the lie. I didn't replace it with Ethylene Glycol until probably 2005. In 2015 it suffered an intake gasket failure. Replaced it with steel reinforced intake gaskets and all is fine.
Where GM screwed up was in the marketing. Telling new car buyers they could go 5 years and or 100000 miles without a change of coolant. As far as I am concerned all vehicle owners should flush and refill their coolant every 24 months regardless of miles. Better yet flush out every drop of Dex orange and use a green coolant.
@@milwaukeebiker Smart to change it every 36 months. I say 24 and I took the DEX out my Buick 3.1 2000 Century when new. Now at 86000 miles and no problems yet.
In my opinion you have that backwards. Dex Cool is a very good product but the engines gm put it in were not designed for it. The problem is b not being compatible with a
They knew it would fuckup the engines. They gotta keep people buying new cars every few years. GM pays engineers to make things flawed to keep selling new junk on wheels.
The reason is that the Dex Cool formulation under ideal and proper circumstances not only offered superior corrosion protection versus standard coolant of the time, but it also offered a longer service interval than the conventional coolant that was being used prior to Dex Cool. The problem was that when not under ideal conditions, Dex Cool could also become highly acidic and start attacking materials that were commonly being used at the time in gaskets and engine components. This would not have been an issue if vehicle owners checked their vehicle fluids regularly such as in this case the coolant and simply kept the fluid level topped off so as to prevent air from mixing in with the coolant which then would initiate the rapid decline of coolant composition in to an acidic form that would do the damage. In addition to this, because of the extended service interval (5 year for Dex Cool vs 1 or 2 years for standard coolant) it became much to easy for owners to completely forget about servicing the coolant being you wouldn't even need to think about for a good stretch of years and so people got out of the habit of changing their cars coolant at all. This is also why you hear such opposite stories when it comes to Dex Cool. Some people stating how problematic the stuff is/was, versus other people who mention how they've run nothing other than Dex Cool for 15 years and 350k miles with no issues, but the later group of people also stayed proactive with their vehicle maintenance as well as checking fluid levels and topping off as necessary along the way, thus they never let the conditions arise that would lead to the Dex Cool becoming acidic in the first place. Was Dex Cool superior to the standard coolant that was being used at the time? In many ways, yes it was. Was introducing a new coolant that was designed to go for 5 years/100k miles a good idea considering that prior to that the standard recommendation was to change out coolant every year or two? Well therein lies the dilemma in that people no longer felt it necessary to check their coolant level/condition when situations such as low coolant levels and or coolant system leaks occurred (leading to air getting in to the system and fluid), what was supposed to be a superior coolant would quickly turn in to a monster and damage would occur. For people who have made it hundreds of thousands of miles running the Dex Cool there would be no reason for them to switch over to anything else as they obviously know what they are doing when it comes to maintaining their vehicle(s) , whereas for people that are not so sure they always do proper maintenance and regular inspection then perhaps they may be better off changing their coolant out to an OAT or HOAT coolant (as long as its done properly) either of which have less of the "jekyll & hyde" characteristics. Of course with many manufacturers now committing to converting over to all electric vehicles in the near future, this issue will become less and less relevant to car ownership.
Its not lifetime. It's long life. They recommended 100k mile change. Most people NEVER checked or changed the coolant..it's a lack of proper maintenance.
Charles Chaney We have it in fleet vehicles that strictly follow GM maintenance schedules and never had a problem. A bunch of these vehicles have over 300k miles with no issues. So don't tell me it's shit. If you follow the maintenance guidelines provided by GM you won't have any issues.
Bob Piff, had enough and dealt with enough of it. My family owns it's own shop and you've not a clue. Lmfao, you are clueless. It's trash Nd even eats metal due to its acidity. I know and have worked on enough to know it's trash. So bye Felicia.
Charles Chaney Like I said, then you are working on vehicles that haven't been properly maintained. As far as it eating metal, that's bullshit and you know it. We have hundreds of vehicles that run it and we never have issues with it. I have 30 years experience as a fleet mechanic. Many of our vehicles are creeping up on 400k miles. Out of our pool of hundreds of properly maintained vehicles, NOT ONE has had dexcool isses.
You want to fix it for good. Flush all that shit out. Then use Prestone Coolant. Then peel that shit sticker Dex Cool off! Problem solved. As the United States does not have shitty water supply, like the EU! Which is why it even exist to start with....
@whacky pax I change the Dexcool every 25K.... This is all made up BS as I have also owned two cavaliers and another Sunfire in the past all Dexcool...never an issue at all. It turns to sludge because either the owner mixes another coolant with it or they never bother to change it ever.
@@omniken66 The entire issue is based on what GM claimed. They claimed 100K mile coolant. People believed they didn't have to change it if they owned the car for 10 years and yet only had 90K on the clock. You're changing it every 25K. This would be like changing your oil every 2K miles. Of course, you're going to eliminate most chances of a problem. Air and Dexcool do not play nice over time and if you miss that window where air sits in the cooling system too long, you will end up with either a milkshake, or mud. I've seen it firsthand.
@@hav2win The "people" your describing will basically do that with any car they own...they don't do any maintenance to the vehicle until it breaks down.
@@hav2win The Dexcool they have now is different than the Dexcool in the 90's if someone or anyone is grossly negligent and basically just puts gas in their car...they deserve what's coming to them. I change my own coolant every 10K and sparkplugs every 8K even though they're iridium...I don't care. Change oil every 2500 miles or sooner three things that will have most cars running over 200K all three of thoise things for less than $90...go to a shop and they'll charge you over $600
I have a 2004 Pontiac with 183,000 on it runs Dexcool just fine no leaks of any seals headgasket is fine water pump still pumps and car dose not overheat and speaking of heat lots of heat in the cabin at wintertime. But I guess Dexcool is bad
We cannot control what you and others us for coolant, nor the frequency of the service on the cooling system, hence we must make the best gasket possible!
Well checked 2000 Pontiac grand am reserve tank is cylinder shape. There is brown sludge in only the top haft on the underside but only at each end not in the middle and none on the bottom haft of reserve tank. I say that because reserve has a seam bit more then haft way up running around it and definitely no sludge below that seam. How bad the sludge maybe esle where like hoses or engine parts I don't know. I hope that the way the car is driven with low klms compared to year that all or most sludge went into the reserve. Got photos but not sure how to post here if you can. Again coolant still very orangey in the reserve. Not brown. I use Cdn Tire Prestone says with GM Dexcool. That any better then gm dealer AC Delco etc ??? Car starts fast seems to run very good.
If you have RED coolant in your system .I WOULD HIGHLY CONSIDER flushing out your entire system and refill with GREEN ANTIFREEZE. GM designed DEXCOOL to eat away at hoses and gaskets for financial gain.
Okay now I am worried. I can not remember from factory if my 2000 Pontiac grand am gt came with green regular coolant and ton of yrs ago I changed it to orange dexcool long life from Canadian tire not the GM DEALER. Or if it always had orange dexcool long life. My car spends most of its life in storage with about 1000 to maybe 2000 klms put on it each year for several yrs now. It's only at 87000 klms not miles now. Last I looked it is still pretty orange. Last changed oh god 8 or more yrs ago. Should I panic get it not just changed but flushed and put I guess prestone yellow long life in it. Have not found up here anyone who actually does a pressure flush just hose flushes complete system heater core etc. Is that going to be an issue with changing coolant types. My car is pampered not alot of hot driving or dirty. Less then hour continiuos driving when i do drive it. HELP
Well that makes sense, I've seen tons of Intake Manifold Gaskets in my time. But I once did them on a GM 4.3 V6 and the Gasket looked so overengineered it looked like NASA made it. LOL, now I know why!
I am going to change my 2012 Chrysler 200s. 3.6 engine over to conventional green antifreeze after flushing coolant out. Good riddance dexcool. Also known as DEXDEATH ! !
Funny I just watched a video that is from 1996 or so that said DeX Cool is a 5 year 100,000 mile coolant and not a lifetime coolant like Bill said. Seems to me someone was giving bad information like what Bill did by calling it a lifetime coolant.
So people honestly think that GM would sabotage their history their reputation their customer base & customer loyalty for a few $$$ worth of unscheduled car maintenance?! That doesn't make automotive industry longevity sense to me at all! knowily using a potential "liability" threat not only doesn't make sense it ruins your overall profits! If Dexcool was such a highly dangerous internal components issue then their should have been an all out bulletin & potential liability act on GM! Would GM intentionally do this to ruin it's reputation & potentially loose thousands of loyal customers to supposedly gain more revenue from repair maintenance?? Sounds like self destruction to me which doesn't make a bit of sense at all! I've never had any issues with sludge build up or leaking seals since 1997! My 2003 Gmc Envoy is running just fine with over 220,000 miles on it with Dexcool! Yea I've replaced radiators(due to plastic part leaking) & water pump(propably because of getting from Advance / Autozone remanufactured) but never noticed any signs of Dexcool as the culprit.Think about it!
geminiwilliams037 They made a new coolant without taking material components into the equation. Bad oversight, but it got fixed. My 2014 Ford Escape uses dexcool. It also uses a transmission that was a co designed with GM. The orange stuff is fine. But if given the choice, I would exchange for hoat or green inorganic.
Konrad Ford. Thanks for your input. Like I've said me personally hasn't had any issues like some ppl here are explaining. Maybe I'm lucky but I doubt it. Over 220,000 on my Envoy & none of those issues with Dexcool so don't know?
@@justmy2cents_ Air leaks and over extended intervals will cause issues. Same can be said of any other fluid but Dexcool isn't an issue and hasn't been for a very long time. My escape has only needed a top off. Oh well.
When that aweful coolant destroyed my 3.1L beater cars gaskets I used these gaskets and never had a issue. Great product, but you guys shouldn't have to do so much work for another company who poured acid in our engines amd told us it'll last a lifetime. Yeah maybe the lifetime of the engine because the coolant destroyed it early
GM didn't honor the warranty, you had to get in on the lawsuit at the time that a lot of gm owners did ( including myself and wife for both our cars)in order to get some money back to pay for the repairs.
@@AdamSmith-gs2dv Use Thermocure rust remover and flush. It is great stuff. I flushed the remnants of nasty Dexcool and the complying rust right out. My radiator looks new inside. Prestone American car universal 10year/300K mile stuff is running great. Temps perfect at 195 on a 2002 3.8 liter LeSabre. Set at -34 degrees mixture.
dexcool sucks regardless of air in system it eats rubber and plastic. A water pump that lives 150k miles with green lasts 25k with dexcool. Never run dexcool regardless of what this guys says is fixed
if you use Evans waterless coolant it would be technologically superior and perform better! The engine will cool better w/ it and it will not corrode hence all the components will last much longer! water is a corrosive! ( well all the chemicals /minerals in it that will cause a reaction are!) 🙂
HA HA HA HA HA SHE IS YOUNG AND HE IS OLD !!! GET IT??? so contrived, obviously scripted... try just having a conversation, speak naturally. Podcast format.
I am redoing a 1997 Cadillac Sedan Deville from the ground up. Thanks Bill for your advice. Flushing the system now, and switching to the Green antifreeze.
@ 2:30 Bill The end customer & GM thanks you for your 20+ years of tireless service. It takes a special person to actually make an effort to solve problems & not just deny it till its out of warranty.
I love how you guys are just honest about the design process
I understand that. I worked for McDonnell Douglas aircraft. We built our planes so well they would last 50 plus years which meant customer did not have to buy new as often. It screwed us in the end. Boeing built a 20 year plane at a good price and bought MDC.
It’s not even a bad coolant. Just gotta make sure when you change your coolant you put the exact same coolant back in the system. People run into issues when they change their coolant and add the green stuff and it mixes with the orange Dexcool that might still be in the engine block and that’s when it turns everything to sludge when the two coolants mix. Dexcool is pretty good at lasting a long time you shouldn’t need to change it unless you notice it’s looking dirty in anyway. When you go to buy Dexcool it usually says on the back made for GM vehicles and it should say Dexcool on it
If i wanna to change from dexcool
I have to use something similar such as wg11 wolver ready to use or kfs12 liquli moly and the both from Germany
Been buying chevy cars and trucks since 2000 and never had one issue with dexcool. I maintain my vehicle(s), theres no such thing as a lifetime fluid/1 year engine oil...

1:40 WHEN THE ANTIFREEZE GOT LOW in the cooling system, it was replaced by AIR.
AIR COMBINED WITH ANTIFREEZE and formed an ACID. The acid attacked the black plastic carrier used in those OE style gaskets, then _____

1) 3:40. We also REPLACED the SILICONE RUBBER, WITH HNBR RUBBER.
That's the stuff they use in batteries to separate the cells; so it's very resistant to acid.
2.) 3:49 We noticed on the OE parts, that technicians sometimes OVER-TIGHTENED the gaskets, sometimes causing failure.
❤️So we built in steel load limiters to solve that problem.
3.) 4:02 We saw another problem :
.We designed an RTV DIVERSION CHANNEL on this gasket, so extra RTV was diverted AWAY from critical sealing areas.

It was also the 3800 series motors to.
7 years late. Is the 5.3L vortec susceptible to this manifold gasket+dexcool+air=coolant acidic failure situation? I chased a leak for about 5 months and now worried about the long-term damage.
So did GM assembly processes change over to your new design in gaskets?
Does the coolant turn into a clear liquid when it turns into pure acid? Mi vehicle is currently dripping that from what looks like oil pan. Maybe the block cover it's called?
It's not OAT antifreeze. It's DEXKILL in particular. It does a lot more than just damage gaskets. It starts out as a liquid, and turns into a solid inside the engine, plugging up all the coolant passages and destroying the engine. I have torn down dozens of GM engines, some as new as 5 years old, that had the water jackets around the cylinders more than half plugged with a brown gooey waxy substance. It also plugs up the radiator, heater core, thermostat, coolant hoses, and even the water pump. If you have a GM vehicle, GET THIS STUFF OUT OF IT RIGHT NOW!!!. I recommend replacing it with Prestone OAT coolant. It has proven to be safe for engines, including aluminum engines, which can be damaged by the silicates that were used in older types of coolant designed for cast iron engines. It has nothing to do with the engine. DEXKILL will destroy any engine. In any vehicle, regardless of brand. And it is the ONLY so called "coolant" that has been known to cause this problem. Most auto manufacturers have their own brand of coolant these days, but not a single one of them have been known to cause problems, EXCEPT DEXKILL.
So I’m good to use Preston dexcool? I want to change mine here soon
Prestone*
I’m at 120k and thinking of switching to Toyota Super life (the pink stuff) I have a Pontiac vibe 07 which is essentially a matrix anyway......
Dexcool is fine....had it in my trucks since 2004....Still going strong, no issues.....
I used Dexcool in my 1984 GMC high sierra, wondering if I made a mistake ?..
The chemical BILL is talking about is 2-EHA which is found in DEXCOOL it softens gaskets that are not compatible with it and weakens the gaskets
Softens the gaskets, eats it and gels up.
Ive never had an issue with dexcool in my 2004 trailblazer ext 4x4 with the 5.3L vortec and it has 322k miles on it...
@AVERAGE JOE As long as they didn't mix the two different formulas and did a THOROUGH clean water flush first.
Great questions and answers, very informative. For these critic comments, looks like you paid no attention to what people where saying. Instead you write sentences of idiotic comments. Purpose of this video is to deliver information about a product and improvements and it is done professionally. Thank you MAHLE.
I bought a 1997 Chevy Suburban from the original owner. It has the 5.7 Vortec engine. How can I find out if the issue of the Dexcool antifreeze/ coolant had been repaired under the warranty?
I just ordered two sets of the premium gaskets, the steel was grey on one set and black on the other, both have the same part number. I went with Mahle brand because I know the design is well tested through R&D, even if most everything online says FelPro is the only gasket to use. The shop that built my engine cheeped out on everything and I'm sure the intake gaskets are no exception. The cooling system also leaked and your video concerns me because of air entering the cooling system.. Thanks for the honest opinion of Dex-Cool and the reason gasket failures are such a problem.
What other damages when it's acid fluid?
There is a fart around 4:40-4:42😂
Yes there is XD

No it’s the girl saying wow listen again
Toot toot
Undeniable air biscuit, lmao.
It's really cool to hear what exactly the problem was and how redesigning the parts fixed it.
And today Ford uses it. Along with virtually every All Makes and Models coolant is a DEXCOOL clone.
I just purchased an 05 Buick Century Limited. Was this car apart of the new gasket change? or would it still have the old gasket? It's got 153 k miles on it. Just opened the radiator cap to see some build up clinging to the sides of the opening. I plan on changing the coolant immediately, but would like to know what I"m up against here. This news is pretty devastating to a person who had no idea such an issue existed!!
If your radiator coolant inside your radiator is RED- thats dexcool NO GOOD! Flush out your cooling system inc. through the heater core, I would also replace thermostat and USE GREEN PRESTONE COOLANT! Dexcool was designed to eat away at your motors hoses and gaskets for FINANCIAL GAIN by GM! CLASS ACTION LAWSUITS ALMOST BANKRUPT GM!
I already changed the gaskets in my 1994 3.1L, so i know what he is talking about. The new improved ones have the steel. The original gaskets look so frail and cheap oh and i have never used DEX, i use the green stuff and no problems.
Which green coolant excactly
@@cdf347 Inorganic green. It can be found in store brands, motorcraft green, prestone prime green.
Mine smells like burning silicate ik cause I've burnt silicone before but it smells mote sweets so I think my car is burning cooling cause it's not a leak cause the level barely changes an my car hasn't over heated
@@cdf347 youre burning coolant, a head gasket problem
@@JuvenalMena my car isn't it was bulletproofed an studded to fix the design of the 00-05 devilles i was just asking which brand, type stuff like that but ives figured that out its been 2 years 🤣🤣

I'm starting to see a pattern Bill. Glance at Bill. What else was a problem. Glance at camera.
Just don't run dexcool
Thx!
Actually a very good coolant. Maintenance is the key
He answered some issues do years of no one really giving a real answer 😠 for. Thanks
Even with gasket changes multiple times, my Pontiac Montana van still went through all of its gaskets after just a few months. Never buying a GM product again.
We have a 2006 Buick Lacrosse 3.8l that still has Dexcool in it ( purchased last June ) . No pressurized coolant overflow tank .
Would this engine have the " good " gaskets from the factory or " problematic " gaskets ?
Shortly after we purchased it , I replaced the black plastic coolant elbows , radiator hoses and heater hoses . Refilled the cooling system with a new gallon of Dexcool .
Will changing the coolant , this way , help the situation ?
We also have a 2015 Chevy Sonic 1.8l , purchased new . At 2 years , I dropped the lower radiator hose and refilled it with new Dexcool . Will this type of servicing help this car ? ( it has a pressurized coolant overflow tank . )
Thanks , :-)
Wyr
God bless
your doing the right thing. dexcool isnt the greatest but if changed when supose to its perfectly fine.
Probably the improved design, but it would be prudent to change the coolant!
Wyr Twister ggg
This also happened to the Buicks with the 3800. i have several and they all failed with dexcool. I understand they fixed them and all that but I also understand I'm just not going to take the chance on it and I change them to green antifreeze . If I buy any GM product from the '90s to the mid-2000s I immediately flush out that all the coolant and put the green crap in. never had a problem like that. im looking at buying a 2000 LeSabre tomorrow 60k miles , guys great grandmas car, has the dexcool in it , that's being changed right after I drive it home. it's either that or I KNOW I'll have to change the gaskets (unless the dealership already did that) I love the engines of GM cars of the 90's and early 2000's but I am sick of doing intake gaskets on them ha ha .
Jasper Engines and Transmissions,the gasket sets come with the metal intake gaskets with their 350 and 4.3 vortec reman engines including the 3100 and 3400 engines.Every plastic intake gasket got thrown away.
So, this is a sales spiel for a particular gasket? I have a 2007 Hummer H2, which has had the same OEM anti-freeze for 12 years... I am about to do a radiator flush and fill with new anti-freeze, the Manual says, "50/50 mixture of clean, drinkable water and USE ONLY GM DEX-COOL(R) or Havoline DEX-COOL(R) coolant. The Hummer has been GREAT to me for 12 years, is there a concern about my refilling the radiator with DEXCOOL? Replacing gaskets on an engine that has no issues is not happening, so which is the safest coolant?
Just wondering what you found out and decided to do?
@@bobcat1 DEX-COOL is the best, most effective coolant for late model Chevy engines WHEN USED PROPERLY, which means you MUST bleed your radiator and engine water chambers to get all air/oxygen out of the system.
It is excess oxygen in the system that cause the Dex-Cool to become acidic, caustic and damage OLD/LEGACY gaskets. Most NEWER gaskets handle Dex-Cool equally well, but the key is to BURP or BLEED the air out of the coolant system as best you can.
My 2007 Hummer H2 has been running Dex-Cool in it's radiator since BIRTH/2007 and there are no signs of any gasket or leak issues whatsoever.
Google BURP coolant for instructions on how to purge air from your system.
I have NEVER in the 14 years I have owned my Hummer seen a coolant temp above 198, in fact... it always runs at 198 degrees.
Since I wrote the original comment, my wife and I have driven 8400 miles, 22 states over a 2 month period between Sept. - Nov. 2020, every terrain type possible, Grand Tetons, Yellowstone, Custer Battlefield, Devil's Tower, Bear Tooth Pass (Scariest Road in America at night in dense fog. If you want to test brake pads, this is the road to do it.), Sturgis, Badlands, Crazy Horse Monument, Mount Rushmore, Memphis, Nashville, Biltmore Manson/Estate, Mayberry RFD/Mount Airy, NC, Ocean City, MD, Kitty Hawk, Cape Hatteras, NC, New Orleans, at the border in Texas during an ice storm, all places in between and a return to Las Vegas without any issues whatsoever.
Never saw a coolant temp above 198 degrees.
Doesn't matter what coolant you use. That same shit happens to any cooling system that's not maintained like it should be. And the new gaskets still fail after 7 to 10 years.
Dex Cool is a special case, it's not uncommon for dexcrap to eat gaskets in 2-3 years tops, and even better is it moves the plastic sludge it creates into the water jackets, and water pumps. Just stick with the green stuff, and you won't have any problems. Any car with dexcool in it that I end up with gets a full flush out and swap to green. Oh, and dexcool will also eat any composite (plastic) intake manifolds it touches too, so even with new gaskets, you're still going to get leaks and need to buy a new plastic intake.
@@Mavairo Ford doesn't use Dexcool. Why do their intakes turn to shit over the years? That's just what happens with plastic. The gaskets failing early with Dexcool issue was addressed over 15 years ago. Hang that argument up already.
@@Carlitosway211 Why run Dexcool at all? It's pretty well documented, and it's no more protective than Prestone's green, and it's more expensive. Stop being a gm fanboy, it's a fuck up, pure and simple that costs more, and doesn't last any longer than green at best, and destroys older plastics at worst. btw Ford used a similar compound at one point which also ate plastic.
And there's plenty of cars out there still on the older gasket design, swapped to green that haven't eaten away. I wonder why that is. It couldn't be because Dexcool sucks.
@@Carlitosway211 My Ford escape uses dexcool.
What everyone’s failing to say it’s not Dexcool that’s ruining the vehicle it’s people thinking Dexcool is bad and they change it out with the green stuff and when other coolant mix with Dexcool that’s when everything turns to sludge and eats the rubber hoses away and breaks water pumps gaskets.
Damn is this why I had to do intake gaskets twice in my 1996 GMC 5.7 extended short box, I got rid of that otherwise great truck because of that issue
My 1995 Impala SS had the green stuff from factory so I avoided dexcool issues. Most of the cars by 2003 had the issues worked out and no more problems
I can't believe I actually muscled through that
didn't change the composition of dexcool?
Im havin to do head gaskets on my 6.6 duramax . Im switching to the green stuff . Flushed the system real good . No more dex cool . Looks like dex cool eats aluminum also 😳
I will add to story. I got rid of my 2007 Pontiac grand prix 3.8 NA last yr because it I think had a coolant leak or air leak ??? That coolant at 205000 klms not miles now a ton of sludge brown and white mostly brown. I believe I had an intake leaked repaired by GM DEALER on 2000 Pontiac grand am that I am way back 2003 or later. So don't know how much of a drain it would have had and likely then they would have put dexcool in it also then. Few questions and concerns here. PLEASE tackle them in detail from these two messages thank
Dexcool will turn that way if it has a major air leak. Also sounds like you did not change it when you should.
Just shows that socalled development isnt always good.
um,,never had any issues with dexcool,,just changed my antifreeze in my 97 Trans AM today with it,,
I've been a mechanic for 35 years on all makes and models. I own only GM at least 3 at a time and 7 right now. The coolant gets changed every 3 years in each one whether someone else thinks it needs it or not. Never any kind of gasket failure.
I had DexCool in my 96 GMC Z71 and believed the lie. I didn't replace it with Ethylene Glycol until probably 2005. In 2015 it suffered an intake gasket failure. Replaced it with steel reinforced intake gaskets and all is fine.
Where GM screwed up was in the marketing. Telling new car buyers they could go 5 years and or 100000 miles without a change of coolant. As far as I am concerned all vehicle owners should flush and refill their coolant every 24 months regardless of miles. Better yet flush out every drop of Dex orange and use a green coolant.
@@milwaukeebiker Smart to change it every 36 months. I say 24 and I took the DEX out my Buick 3.1 2000 Century when new. Now at 86000 miles and no problems yet.
The other moters you forgot that the L32/L67 3.8L 3800 Series II N/A ans Supercharged and the cadillac Northstar 4.6L was also infected by tgis
Bill is worse than joe at the teleprompter lol
Should keep hands above table while giving a presentation regardless if in person or on video.
So, Problem is A, and it affected B. You updated B to make it work with A. Got it.
In my opinion you have that backwards. Dex Cool is a very good product but the engines gm put it in were not designed for it. The problem is b not being compatible with a
Terrible script reading
My 2001 Chevrolet Lumina was killed by dexcool. RIP Best car I ever owned
after how many miles?
mine died at 134k worst car I ever owned a money pit that 3.8 is junk I fix stuff my self repair after repair felt like I was rebuilding the car
Why did manufacturer switch over to Dex-Cool in the first place?
They knew it would fuckup the engines. They gotta keep people buying new cars every few years. GM pays engineers to make things flawed to keep selling new junk on wheels.
It is long lasting and offers some of the best corrosion and erosion protection. It is just chemically agresive and does not tolerate air bubbles
The reason is that the Dex Cool formulation under ideal and proper circumstances not only offered superior corrosion protection versus standard coolant of the time, but it also offered a longer service interval than the conventional coolant that was being used prior to Dex Cool. The problem was that when not under ideal conditions, Dex Cool could also become highly acidic and start attacking materials that were commonly being used at the time in gaskets and engine components. This would not have been an issue if vehicle owners checked their vehicle fluids regularly such as in this case the coolant and simply kept the fluid level topped off so as to prevent air from mixing in with the coolant which then would initiate the rapid decline of coolant composition in to an acidic form that would do the damage. In addition to this, because of the extended service interval (5 year for Dex Cool vs 1 or 2 years for standard coolant) it became much to easy for owners to completely forget about servicing the coolant being you wouldn't even need to think about for a good stretch of years and so people got out of the habit of changing their cars coolant at all. This is also why you hear such opposite stories when it comes to Dex Cool. Some people stating how problematic the stuff is/was, versus other people who mention how they've run nothing other than Dex Cool for 15 years and 350k miles with no issues, but the later group of people also stayed proactive with their vehicle maintenance as well as checking fluid levels and topping off as necessary along the way, thus they never let the conditions arise that would lead to the Dex Cool becoming acidic in the first place. Was Dex Cool superior to the standard coolant that was being used at the time? In many ways, yes it was. Was introducing a new coolant that was designed to go for 5 years/100k miles a good idea considering that prior to that the standard recommendation was to change out coolant every year or two? Well therein lies the dilemma in that people no longer felt it necessary to check their coolant level/condition when situations such as low coolant levels and or coolant system leaks occurred (leading to air getting in to the system and fluid), what was supposed to be a superior coolant would quickly turn in to a monster and damage would occur. For people who have made it hundreds of thousands of miles running the Dex Cool there would be no reason for them to switch over to anything else as they obviously know what they are doing when it comes to maintaining their vehicle(s) , whereas for people that are not so sure they always do proper maintenance and regular inspection then perhaps they may be better off changing their coolant out to an OAT or HOAT coolant (as long as its done properly) either of which have less of the "jekyll & hyde" characteristics. Of course with many manufacturers now committing to converting over to all electric vehicles in the near future, this issue will become less and less relevant to car ownership.
agree
@@racers115
Its not lifetime. It's long life. They recommended 100k mile change. Most people NEVER checked or changed the coolant..it's a lack of proper maintenance.
Bob Piff, no dexcool is shit.
Charles Chaney
We have it in fleet vehicles that strictly follow GM maintenance schedules and never had a problem. A bunch of these vehicles have over 300k miles with no issues. So don't tell me it's shit. If you follow the maintenance guidelines provided by GM you won't have any issues.
Bob Piff, had enough and dealt with enough of it. My family owns it's own shop and you've not a clue. Lmfao, you are clueless. It's trash Nd even eats metal due to its acidity. I know and have worked on enough to know it's trash. So bye Felicia.
Charles Chaney
Like I said, then you are working on vehicles that haven't been properly maintained. As far as it eating metal, that's bullshit and you know it. We have hundreds of vehicles that run it and we never have issues with it. I have 30 years experience as a fleet mechanic. Many of our vehicles are creeping up on 400k miles. Out of our pool of hundreds of properly maintained vehicles, NOT ONE has had dexcool isses.
Bob Piff, sure Bob sure...
You want to fix it for good. Flush all that shit out. Then use Prestone Coolant. Then peel that shit sticker Dex Cool off! Problem solved. As the United States does not have shitty water supply, like the EU! Which is why it even exist to start with....
3800 v6 as well
???? Has the formula been updated ????
Been running my 05 with Dexcool for 15 years now....never a problem! Much of this is just straight up BS!
@whacky pax I change the Dexcool every 25K.... This is all made up BS as I have also owned two cavaliers and another Sunfire in the past all Dexcool...never an issue at all. It turns to sludge because either the owner mixes another coolant with it or they never bother to change it ever.
@@omniken66 The entire issue is based on what GM claimed. They claimed 100K mile coolant. People believed they didn't have to change it if they owned the car for 10 years and yet only had 90K on the clock. You're changing it every 25K. This would be like changing your oil every 2K miles. Of course, you're going to eliminate most chances of a problem. Air and Dexcool do not play nice over time and if you miss that window where air sits in the cooling system too long, you will end up with either a milkshake, or mud. I've seen it firsthand.
@@hav2win The "people" your describing will basically do that with any car they own...they don't do any maintenance to the vehicle until it breaks down.
@@hav2win The Dexcool they have now is different than the Dexcool in the 90's if someone or anyone is grossly negligent and basically just puts gas in their car...they deserve what's coming to them. I change my own coolant every 10K and sparkplugs every 8K even though they're iridium...I don't care. Change oil every 2500 miles or sooner three things that will have most cars running over 200K all three of thoise things for less than $90...go to a shop and they'll charge you over $600
I have a 2004 Pontiac with 183,000 on it runs Dexcool just fine no leaks of any seals headgasket is fine water pump still pumps and car dose not overheat and speaking of heat lots of heat in the cabin at wintertime. But I guess Dexcool is bad
So rather then fix the actual problem ie the coolant they spent millions of dollars coming up with a new gasket.... Good work guys.
We cannot control what you and others us for coolant, nor the frequency of the service on the cooling system, hence we must make the best gasket possible!
Well checked 2000 Pontiac grand am reserve tank is cylinder shape. There is brown sludge in only the top haft on the underside but only at each end not in the middle and none on the bottom haft of reserve tank. I say that because reserve has a seam bit more then haft way up running around it and definitely no sludge below that seam. How bad the sludge maybe esle where like hoses or engine parts I don't know. I hope that the way the car is driven with low klms compared to year that all or most sludge went into the reserve. Got photos but not sure how to post here if you can. Again coolant still very orangey in the reserve. Not brown. I use Cdn Tire Prestone says with GM Dexcool. That any better then gm dealer AC Delco etc ??? Car starts fast seems to run very good.
I am a robot.
Boop blorp beep.
If you have RED coolant in your system .I WOULD HIGHLY CONSIDER flushing out your entire system and refill with GREEN ANTIFREEZE. GM designed DEXCOOL to eat away at hoses and gaskets for financial gain.
TRUTH4U2NO does that include orange withe the red?
@@abcxyz3783 you can use red coolant from other manufacturer, not the GM Dexcool...
Okay now I am worried. I can not remember from factory if my 2000 Pontiac grand am gt came with green regular coolant and ton of yrs ago I changed it to orange dexcool long life from Canadian tire not the GM DEALER. Or if it always had orange dexcool long life. My car spends most of its life in storage with about 1000 to maybe 2000 klms put on it each year for several yrs now. It's only at 87000 klms not miles now. Last I looked it is still pretty orange. Last changed oh god 8 or more yrs ago. Should I panic get it not just changed but flushed and put I guess prestone yellow long life in it. Have not found up here anyone who actually does a pressure flush just hose flushes complete system heater core etc. Is that going to be an issue with changing coolant types. My car is pampered not alot of hot driving or dirty. Less then hour continiuos driving when i do drive it. HELP
Look up your manual. It will say. If you're worried, then just change you green if worried.
Well that makes sense, I've seen tons of Intake Manifold Gaskets in my time. But I once did them on a GM 4.3 V6 and the Gasket looked so overengineered it looked like NASA made it. LOL, now I know why!
Great video Ya'll

Glad, I only have a few GM vehicles
I am going to change my 2012 Chrysler 200s. 3.6 engine over to conventional green antifreeze after flushing coolant out. Good riddance dexcool. Also known as DEXDEATH ! !
that isn’t dexcool. That is probably an OAT maybe even Hoat but I believe the FCA version is different.
Funny I just watched a video that is from 1996 or so that said DeX Cool is a 5 year 100,000 mile coolant and not a lifetime coolant like Bill said.
Seems to me someone was giving bad information like what Bill did by calling it a lifetime coolant.
Dex-cool is straight trash.
5 years or 100,000 is just about the lifetime for many GM vehicles
@@schnoodle3 I have had many GM vehicles that have gone over 100,000 miles and definitely more than 5 years
So people honestly think that GM would sabotage their history their reputation their customer base & customer loyalty for a few $$$ worth of unscheduled car maintenance?! That doesn't make automotive industry longevity sense to me at all! knowily using a potential "liability" threat not only doesn't make sense it ruins your overall profits! If Dexcool was such a highly dangerous internal components issue then their should have been an all out bulletin & potential liability act on GM! Would GM intentionally do this to ruin it's reputation & potentially loose thousands of loyal customers to supposedly gain more revenue from repair maintenance?? Sounds like self destruction to me which doesn't make a bit of sense at all! I've never had any issues with sludge build up or leaking seals since 1997! My 2003 Gmc Envoy is running just fine with over 220,000 miles on it with Dexcool! Yea I've replaced radiators(due to plastic part leaking) & water pump(propably because of getting from Advance / Autozone remanufactured) but never noticed any signs of Dexcool as the culprit.Think about it!
geminiwilliams037 They made a new coolant without taking material components into the equation. Bad oversight, but it got fixed.
My 2014 Ford Escape uses dexcool. It also uses a transmission that was a co designed with GM.
The orange stuff is fine. But if given the choice, I would exchange for hoat or green inorganic.
Konrad Ford. Thanks for your input. Like I've said me personally hasn't had any issues like some ppl here are explaining. Maybe I'm lucky but I doubt it. Over 220,000 on my Envoy & none of those issues with Dexcool so don't know?
@@justmy2cents_ Air leaks and over extended intervals will cause issues. Same can be said of any other fluid but Dexcool isn't an issue and hasn't been for a very long time.

Could have done w/o the chick.
Great acting!
When that aweful coolant destroyed my 3.1L beater cars gaskets I used these gaskets and never had a issue. Great product, but you guys shouldn't have to do so much work for another company who poured acid in our engines amd told us it'll last a lifetime. Yeah maybe the lifetime of the engine because the coolant destroyed it early
GM didn't honor the warranty, you had to get in on the lawsuit at the time that a lot of gm owners did ( including myself and wife for both our cars)in order to get some money back to pay for the repairs.
Yes, just found out about this now and looks like I got screwed, I hate corporate America!
They don’t call it dex kill for no reason
Dex-Cool isn't worth a crap!! Worst coolant ever invented!
I never used this Dex yellow bull..I stick to purple ones..
It’s orange not yellow
Just flush out the dexcool and refill with long life universal antifreeze that is offered by prestone and many other brands
You have to flush extremely well, if you don't and Dexcool and Green coolant meet it will create a gel that will clog up the entire cooling system
Any problems yet?
@@AdamSmith-gs2dv Use Thermocure rust remover and flush. It is great stuff. I flushed the remnants of nasty Dexcool and the complying rust right out. My radiator looks new inside.

dexcool sucks regardless of air in system it eats rubber and plastic. A water pump that lives 150k miles with green lasts 25k with dexcool. Never run dexcool regardless of what this guys says is fixed
sorry but this video was making me fall asleep to scripted
THIS WAS VERY CREEPY
Please don’t waste money on commercials. Hire someone.
if you use Evans waterless coolant it would be technologically superior and perform better! The engine will cool better w/ it and it will not corrode hence all the components will last much longer! water is a corrosive! ( well all the chemicals /minerals in it that will cause a reaction are!) 🙂
That’s why you’re supposed to use distilled water.
