Patching up coolant leak with K-Seal on 2012 Prius
Вставка

- My Prius was getting random misfires, had already changed the spark plugs and ignition coils but was still having issues in the morning. Finally realized that I probably had coolant leaking in through a blown head gasket.
Testing K-Seal as a temporary fix until I figured out a permanent solution. - Авто та транспорт
Thanks for the honest telling of the process. I did not expect the ending.
Pro Tip. If you cant do the head gasket you can take the Oring out of your coolant overflow and it will unpressurize system. It will boil much much easier but pushes way less cooland into the cylinder. working great in winter especially.
Ummm no
Wouldn't this cause a premature failure if the engine itself due to high temp?
@tim z is there any issue not fully close but partial close coolant overflow,also there is side cap to let air out or coolant out ?
@@samtx that cap vents at whatever the cap is rated at . I think 15psi. partial close may be similar to taking out o-ring. Removal of the o ring lets you leave the cap locked on so it cant fall off. I had originally taped the cap loosely. When it starts to misfire and studder on every start up you know you need to quit driving it. If enough coolant gets in it will hydro lock that cylinder then bend a rod or worse.
@@samtx the issue is your coolant system is no longer pressurized which means when you cut off the car it's not forcing coolant back into the cylinders which is causing your misfire on startup. Water boils at 212 antifreeze spoils around 236 and antifreeze at 15 psi boils around 275 I think. So if you will imagine under heavy loads or hot temperatures the coolant near the cylinders is going to boil. Creating pockets of air and possibly cavitation in your water pump area. Running the air conditioner is also going to put more heat in front of your radiator and make it worse. If you drive easy and during cool temperatures it doesn't seem to have a problem running on pressurized. If you were in heavy stop and go traffic you might want to run the heat. I would also note that I would lose a couple cups of coolant a day because being no longer sealed it's going to evaporate.
I used KSeal on my 2012. Worked perfectly. 0 issues. No leak, no knock. Runs like brand new. I wish I would have known earlier!
did you use it exactly like he did or did you do something else? I'm trying to fix mine now
I just added K-Seal yesterday and ran it 15 minutes and rest engine warning. Rough knocking is history.... for now it's a dream come true ... but my question is.. how long does k-seal last or what's the life span for this trouble shooting remedy?
Napa told me to drop K-Sral in the reservoir ** Napa says replace old antifreeze, flush and replace with new. K-Seal Job is to seal and not to be left on the cooling system.
ONLY USE KSEAL IF YOUR SELLING THE CAR
THIS IS NOT A PERMANENT FIX
YOU GUYS ARE SMOKING IT IF YOU THINK SO
Still good? How many miles if knocking back ?
Honest review tks
Hate putting anything foreign into my coolant but.....I used this on the seeping heater core on my 2001 Ram truck and it did work. I'm not sure if I'm seeing a little diminished heat now coming from the heater but we'll see. I'd say always be cautious using anything like this and just don't be surprised if you end up with no heat.
K-Seal saved me a ton on repairs costs for my 2014 LR4. I was losing a 1/2 tank every two weeks. K-Seal can also be used as a preventive treatment.
can I get an update how many more miles did you got out of you car after?
Well I just used it on my LR4 I let it run with the heater on and didn’t overheat is that good ?
Thanks for your video. I have a 2014 Prius 2. I also was receiving misfires, shaking, losing coolant and burning oil at a faster than normal speed. When I purchased my vehicle I would get a oil change every 10K. Now I get a oil change about every 4K miles. I also forgot mention my Prius has over 300K miles. Anyway I spent a little over $3K getting all new spark plugs, injector coils and having that installed by a professional. Sadly that didn't fix the problem of the shaking, misfires and coolant loss. I was spending about $50 a week in coolant. Anyway I seen your video yesterday and gave it a try. Waited for car to cool before applying, did the maintenance run to keep engine running so solution can run through the car. 4 hours later started it back up and it was perfect. Went and got an oil change just in case anything during all that bad driving I was doing mixed in with the oil. Woke up this morning for another cold start. Perfect. Even if this isnt a permanent fix this is great. Thanks
Let me know how long it lasts. Most likely your head gasket is bad which is why your coolant is leaking. Go ask around and see how much a replacement is. Once u replace that you should be good to go.
@@realrandomcarstuff will do
@@realrandomcarstuff I started my Prius today. I have driven 1,859 miles after putting in the k-seal. I didn't have a rough start,but it shook lightly. No noise but the vehicle did shake. Now I check under the hood. I top off the coolant the day I inserted the k-seal. Slightly over like by a hair over full. I may have lost a half inch of coolant maybe. What I also will mention. Maybe a day or two after inserting the k-seal my coolant was a darker color. Looking at it now it seems almost pink again. No check engine light just a very small shake. Just figured I mention it.
@@realrandomcarstuff 4,313 no check engine light but this morning coolant reservoir was half full. Car is misfiring and no check engine light. My question is can I just buy another bottle of k-seal and try my luck for a second time?
@@coreywillis6891 no. I think your head gasket is done. The k-seal can only do so much to keep your car moving until u can find a mechanic to fix that issue
Thank you so much you solve my car problem
Is this the same Prius you cleaned the EGR Valve body and pipe in the previous video?
If you find that your prius knocks on cold mornings just pull up the airbox and wipe the underside of the butterfly valve out with a paper towel there is usually oil and water puddles sitting at the bottom the intake under the valve. Its a defect of the third gen. I own a 2011 its been great but is starting to show its age.
good idea do you know any video demostration of this? thx
Thank you.
Do you know how long before I can’t start it and drive it again
I have a slow coolant leak that isn’t visible. Shop swears it’s not blown gasket. Oil isn’t milky color, no white smoke from tailpipe, etc. I used K seal and a week later my coolant level is where it was before I poured in the K Seal. It’s driving me crazy. The shop told me it’s either a small leak in the radiation plug and I need to replace my radiator or else my water pump is faulty. My water pump is about 60,000 miles old. I’m gonna wait another week to see where my coolant level is then. Maybe it just went down a bit after the K seal but is sealed now?
You have to pour it in when your over flow tank not as full as it was when u recording because of this your k seal was flowing on top of the coolant in the overflow tank and it didn't get a chance to get sucked down into the radiator and to circulate throughout the coolant system
Thanks. If I ever have to use it again I’ll keep this in mind
That's exactly how I added K seal in the reservoir
I have the check engine light P0302, P0300, P0303 on a 255,600 mile Prius V. All 3 spark plugs 9 month old, spark plug rusted so I’d replace all 4 spark plugs and ignition coil. I notice smoke come out of exhaust and the rust I concluded that I had a leak gasket. I use blown gasket sealant. All errors code went away after 2 days drive but on the 3rd day my water pump broke tomorrow I’ll replace the water pump it’s an easy job. Water pump have a life time of 60k-100k mile so I guess the sorta the straw that broke the old camel back while at it I’m to change the thermostat housing too. Hope it’s works.
KSEAL DAMAGED YOUR PUMP AND THERMOSTAT
AND CLOGGED UP YOUR RADIATOR TOO
can I get an update how many more miles you got out of you car?
What happened to this car? I am assuming the head gasget was blown. Did you replace it, or did the engine eventually die?
He traded it in.
Just have a new head gaskets installed
will this damage engine ? and why do coolant evaporate ?
Have you ever replaced the water pump and thermostat and hybrid battery with your old Prius that you trade in
SIMPLEGUY423 nope. I didn’t do any of it. The hybrid battery was still going strong. If I could have changed the head gasket for less than $1000 I would have done so and kept the car. It was running good.
A did same to a 2013 prius v & it lasted about 10,000 miles . But now it just started. To rattle harder than the 1st time last night.. about to do it again tomorrow I drive 200-300 miles a day..
head gasket kit $200-)230. U could find a mobile mechanic.. to do it under $1,500. After this I just need to make some $ for the kit & do it myself.. I have $40 in my account..lol
After you've done it once you can do it for other Prius owners.
How much did you pay for the new car?
Any update on how long this fix lasted for you? Currently have the same issue but have hesitated because I've seen some people recommending not to use products like this. let me know please!
I think it lasted me 800 miles. It just depends on how bad your head gasket is. It there is a big hole then it won’t last long. I would say it’s only good to get you to the mechanic for a more permanent fix.
If your car has a gasket leak/blown gasket use blue devil gasket seal pour n go
its best to dilute it first and also put into top hose not container! for quickest best results!
IT'S SNAKE OIL SON
@@21boxhead it’s not snake oil, it works, just not forever
@@loversandlosers THIS WILL BUY ENOUGH TIME JUST TO SELL IT ASAP
BUT THIS STUFF WILL CLOG UP THE RADIATOR SMALL PASSAGES AROUND THE ENGINE WILL CLOG UP
BUT IF YOU PLANNING ON KEEPING IT
DON'T DO IT THAT'S DUMB
EITHER FIX IT YOURSELF THERE IS PLENTY OF VIDS TO SHOW YOU HOW TO FIX THE HEAD GASKET
OR TAKE IT THE MECHANIC $1200+ TO FIX
AND LAST NEVER NEVER KEEP DRIVING WITH ISSUE FOR LONG
IF YOU KEEP DRIVING WITH BLOW HEAD GASKET EVENTUALLY PISTON ROD WILL BEND AND PRETTY MUCH HAVE TO DO A ENGINE SWAP OR REBUILD
Does a used Prius come with a dental damn?
I was loosing coolent. But noting leaking outside Used 1 bottle K seal. Now coolent leaking under the car and visible, but can't see where it's leaking from. What's wrong with it?
Check the overflow tank to see if you have too much pool or it's being blocked and overflowing onto the ground out a piece of hose from the expansion tank. Kseal sometimes blocks the overflow out to the radiator and they overflow. That's where the coolant could be coming from .
Was that what would have fixed it when you were doing the other video of it
Angel Calderon no. It was separate issues. There was no coolant in the cylinders when I changed the spark plugs and ignition coils. It happened later.
Dude, HEAD GASKET needs proper repair. This kind of treatment will destroy your coolant system instead. After all, you will still to do head gasket replacement, cleaning engine block from this gunk, replace water pumps, may be new EGR cooler, and definitely radiator. Why do you do stupid thing in any modern car?
@@rondhole Read the K Seal reviews and literature. I thought the same way. My car has well over 200,000 miles on it. I wish I had know earlier. There is no way I am paying a dealer 3000.00 to fix a car. I have already flushed the radiator with water and new antifreeze. Zero problems. I can't begin to tell you how much better the car runs. My car had a knock when I bought it, not realizing there was a problem. I was told it was normal for that year. It is fixed. ZERO ISSUES!
@@drquenzer777 200k miles is nothing for Prius, it can run another 300k miles if maintained properly. You should find an experience mechanics for about $1000. Head gasket master does it for $800 in California to Phoenix area, done in one visit. The knock-in first starts is typical head gasket leak from water sitting on the cylinder and causes misfire. Any kind of K-seals will work before you sell it, probably couple thousands of miles.
@@drquenzer777 how many miles have you put on car after kseal if still good now and you flushed right after kseal fix or like others ran for 100 miles ? ,im looking to flush radiator multiple times right after kseal
Weird problem. 2012 Prius, 145k miles. Oil changed religiously at every 10K, 0W20 full synthetic. Never driven at low coolant levels. Sudden loss of coolant on the highway. drove 200 miles one way, no problem. on the way back, stopped at every rest area to add DI water, i.e. every 30 miles or so. In each case, there is still some water in the plastic tank. Engine runs smooth, accelerates smooth, purrs like a cat. No white water vapors in the exhaust. Took apart the front, and looked for pink residue around connections and radiator seal lines. No pink residue. Rubber hoses are tightened with original spring clamps, but no pink leaks. Electric water pump is clean. However, there is pink residue at the back of the plastic overflow tank, the firewall and the drive shaft. Sometimes the leak is so big, that it ends up on the front passenger tire and the passenger side doors. How does it go from inside to the OUTSIDE the vehicle is a mystery. Check engine never shows up. The high temperature light comes on and off, sometimes flashing, sometimes solid, then disappears. Driving around town seems no loss so far. Planning to do a pressure test and exhaust fumes test later on today.
Was the dealership aware of the gasket problem on your trade-in? Or did the K-Seal help hide the issue from their awareness & that way, giving you a better offer for trade-in? Thanks
Riaz yep, I told them. They knew as soon as they looked at the coolant and it wasn’t pink. I told them I put it in so I could drive it temporarily until I could trade it in. I’m sure they changed out the gasket and resold it. There was nothing else wrong with it. I was the only owner and everything including the hybrid battery was still going strong.
@@realrandomcarstuff That's great. How much were they willing to give you on the trade & what was the mileage?
Riaz $1500, 189k miles.
@@realrandomcarstuff Most honest mechanics will do head gasket at about $1000 including machining the head and checking the valves.
@JP JP yes, if you find good independence mechanics, not Dealership. I paid total $1k for the head gasket on my Altima 02 back in 2008. Not that different than Prius besides more pipes on EGR since older car have no EGR, just valve overlap for the same purpose.
Do you still have the second Prius?
I sold it to my sister. It still runs fine.
Hey dude, did you changed the head gasket !
Now your going to need a new water pump, head gasket, radiator and heater cole
Nah why ? Why would he put that in to fuck up all that main come on
@@pono321 you don’t understand how this stuff works huh, noob
@@pono321 THIS IS FOR QUICK FIX
YOU KNOW ANYTHING "QUICK" IS NOT PERMANENT
SO YOU USE THIS STUFF WHEN YOU TRY TO SELL YOUR CAR
@@21boxhead true i was just going to sell the car hahaha but didn’t end up using it and just sold it like that. It was just that when u turn the heater on had a sweet smell, it had a heater core leak but I left like that not worth it. It was for a pt cruiser haha
its liquid copper very simple but effective.
IT'S NOT DUDE IT'S SNAKE OIL
Actually it's a ceramic like a pottery clay and it hardens with the heat of the engine cylinder where it's leaking with some copper particles for added support
It is designed for very small leaves 1/32nd of an inch. That's the smallest line on the ruler. Tiny
It's most effective if you catch it very early we're just starting to become problem then it's a permanent fix. Kseal remains in the coolant to plug up any new small holes that arise.
I've used it a few times on different cars. It is always worked. So far.
My leak is on a line on backside of engine what toyota told me. They said I need to replace the line. Whatever that is
Sounds like it might be the transmission coolant line
Head Gasket Leak u need Blue Devil not K Seal its not really for that
Is it safe to put in the inverter coolant?
J D I would not put it in there.
THAT'S DUMB
NO REASON TO PUT IT THERE
Did that fix it in the longrun
Angel Calderon our 2012 had the same issue and we found out the problem is head gasket. It wasn’t not worth having it done. We decided to add a mix solution for sealing the head gasket (motor purr) it works for almost a year. Add the solution directly to the radiator hose never add it to the coolant reservoir.
@@fancypaul3372 Hows the vehicle doing now?
John Ammann it lasted almost two years. We could have re-applied the mix again but at this point, the car reached 300k adventuresome miles and just sold it last week for a local mechanic. He plans to replace the engine.
@@fancypaul3372 what product did you use?
John Ammann MOTOR PURR SEAL UP RADIATOR HEATER CORE STOP. Bought on eBay
if you clean the egr cooler this would never happened. my prius has 290,000. I had started to get misfires around 245,000. Cleaned the egr and the misfiring went away.
Manuel Salinas man I have 163000 miles in mine. It just started doing this in the mornings. What is the first thing I should have done?? Please give me advice. My cylinder 3 is now misfiring.
Do you have late 2013 or newer model ? They have different head gasket that Toyota revised at that period. Everyone knows 2010-early 2013 models are using old-style head gasket that commonly leak at around 150k miles if you drive in city a lot.
@drew michael Just wait and be passion when it will definitely come back in the BIG way. Most likely you will pay way more than you fix it properly from the first time.
@drew michael Well if it is 10 years old 300k miles car that worth no more than $3000, fixing head gasket properly may cost $1000 and you can use it for 4 or more years until new battery is needed. But if you put this Bar's leak, trade it in in any crooked dealer and let them swallow it.
@drew michael I got those suggestions from more than 3 mechanics when I had exact same problem and quoted for proper fix. We know all dealers are stabbing buyers from the back. I ended up fixing the head gasket and renew valve stems with Felpro Head gasket sets for $1000. It last another 60k miles before I sold it without anymore problem with head gasket.

Simple. If the car has high miles like 250,000+ then a head gasket replacement probably costs more than the car is worth. In that case, there's nothing to lose.
@@frossbog HEAD GASKET REPLACEMENT COSTS ABOUT 1000+ BUCKS
OR DO IT YOURSELF THERE IS LOTS OF VIDEOS SHOW YOU HOW TO REPLACE THE HEAD GASKET
Because while replacing head gasket you might get into other fixes. By the time this issues occur cars usually have low compression and other things to do making it useless to replace gasket, when it needs entire engine rebuild.
@@arthura7442 you are right. But if it is known when it starts having head gasket leaks, it is still worth to do. You can also check the cylinder wall using endoscopy camera first. It is Toyota known problems on Prius. Toyota updated head gasket on 2013 and piston and piston rings on 2015 that reduce oil consumption problem significantly and much less head gasket issues.
@@21boxhead
1,000? You'd be lucky. Anyway it's pointless if your car is old and has high mileage because just about everything else in your engine is probably worn out too. The only thing to do at that point is to remove the engine and have it completely rebuilt. This job is only worth doing if your car is rare or increasing in value, otherwise scrap it or keep using something like kseal until it claps out.
Lol now your problem was someone else’s. Not cool
Lasted 15k
this piece of junk causing massive heater core clogging problem, dont ever think about using it!!!!!!!!!!!!!!!!!
moral of story here! dont buy used cars! for realz
Worst video ever, DO NOT USE HEAD GASKET REPAIR, they absolutely wreck your engine and car, I used kseal for 2 years because I thought, whats the big deal since I planned on replacing the engine, well turns out kseal also plugs your radiator amd your heater core, and possibly it catalytic convertor
Be careful when you use this KSeal shit. I put this stuff in my van's cooling system and it hasn't run since February of 2020. Where do I begin?
I began to have intermittent stalling problems. Everything that looked like either a fuel blockage or lack of spark etc. I even bought a new $93.00 MAP sensor and STILL the problem was there.
So now my engine is essentially running poorly. However I maybe used too much by accident. The head gaskets are a main point of failure if your leaks are else where. The cooling jackets are rather wide BUT the head gasket has small slits that restrict the flow of coolant to prevent over cooling. KSeal CAN stick to your head gasket and slowly DAMAGE your head gasket!!!!
So if you use KSeal my STRONG recommendation is use the absolute LEAST amount of it as possible and when your leaks are sealed CHANGE YOUR COOLANT!!! Or take it to a respectable mechanic within a month. Don't make the same mistake I did!!!
Sigma XIII I use blue devil gasket sealer, that seams to work for me. My pt cruiser is notorious for having bad head gaskets. Since I used it I’ve never had a problem with the head gasket since. If you do plan on using it. Do not add to reservoir, add directly to the radiator. Either by the radiator cap or through the upper radiator hose connected to the radiator. That’s if you so choose to do this again. I am so sorry about your van tho. Hopefully this will help in the future!
Also run the car for an hour or so, if it starts to overheat then turn it off and try again later if you didn’t reach the hour limit.
Nuclear Gaming did you take out the thermostat b4 you installed the blue devil?
Samuel Thurmand III nope, everything still works fine as well
