I'm a retired Ford master tech and I thoroughly enjoy you videos !! I'm sure you have more work than you can shake a stick at. I would have no problem with you working on my vehicles. Thanks again for quality content
This is so crazy!!! I’m a General Manager for Advance Auto and I’m working with a customer on figuring out what the issue is for his 6.4! You are giving me SO MUCH freaking information! We are second sourcing a mishimoto radiator for him and got him a new cap. You are saving lives out here!!!
No wonder Ford diesels had so many problems. It's really amazing how few mechanics take pride in their work. I had to quit the dealerships and go on my own to preserve quality repairs, and an affordable price. Since they made it necessary to pull the cab off the truck to access the engine, I have declined to work with any diesel, in spite of my qualifications. You are an honest mechanic, and this is so rare. Keep up the great work.
Sir, you are the single greatest thing to happen to the diesel community since the invention of the turbo diesel itself. The knowledge you provide in these videos, ESPECIALLY regarding the 6.0, is invaluable. I’m about to purchase a 6.0 King Ranch. Without watching these videos I never would have even considered the 6.0 over a 7.3 or a 6.4, but now I feel confident that I can bulletproof it and keep it in service for hundreds of thousands more miles. Thank you very much for your work.
@semloo The 6.7 is unique because it has two separate cooling systems, two water pumps, two radiators, two thermostats etc. One system for the engine cooling only and the other system for all the emissions systems. This way if the EGR cooler ruptures it wont destroy the engine. BIG PLUS. And YES the cooling caps are updated. It looks like a rats nest under the hood but it seems to work well.
People no matter what motor you have: gas, diesel.... No matter who made it. Listen to this man's words. He is 100% correct. I check all coolant caps every 6 months or before a long trip. Little things like this and proper maintenance (oil changes, etc) will save you a lot of money and make your motor last much much longer. I didn't get 200,000mi+ out of a Chevy 350 by letting things go. All it's ever had was a water pump and A/C compressor. Just by doing regular maintenance It still runs like new everyday. I drove semi-trucks for a living and just by doing good maintenance on them. I only had 2 breakdowns in over 2,000,000 miles. (Neither were major just more than I could fix on the side of the road)
Thanks, Bill. Absolutely correct with this. My 7.3 had a bad cap, and it was still on the reservoir AFTER I rebuilt my engine due to a damaged #8 cylinder.
I have now become a member, I checked mine ( 2006 F-350 6.0 58,000 miles ) right after watching this video, at Auto Zone using there tester, had top pressure of 5 PSI with slow leak to 0 PSI.Thanks and look forward to more information videos.
Just wanted to say thank you, I followed your advice and replaced my cap. I had an intermittent coolant leak on my truck since day 1. I put a new cap on, and found the leak! WATERPUMP! Replaced my waterpump using the video instructions you made, now my leak is gone! Thank you for all the videos you make, you certainly have saved me a pile of cash! Keep doing what you do!
I bough an 2008 power stroke and noticed some coolant underneath the truck a couple days later and decided to try and find out what was causing the problem myself before I took the truck back to the dealer or shop and had it repaired , After I did a search and watched the video I walked out to the truck raised the hood and removed the radiator cap and sure enough it was the old cap with the small spring , I replaced it as you instructed and have drove the truck almost 2200 miles and no more fluid leaks and the truck and I thank you , PS the truck had been into a Ford dealership the month before I bought it for service , I would have thought they would have checked the cap and replaced it since it was the dealership where the truck was purchased .
@TamiyaRunner The physics certainly apply to every motor vehicle that uses coolant. Your cap may still be good because gas burners don't create the heat and pressure that a diesel engine does. But it is a good idea to check it any way.
I have a 2000 E-350 7.3; I had some fuel issues.The last thing I have to do is the # 8 injector that's not shooting oil and is causing a miss and loss of power .Thanks SO MUCH for your videos; They have help me so much, and I have saved so much money doing it my self. Me and my family thank you so much for your time and your videos.
this is great advide and as someone who did a lot of his own mechanical work on his vehicles i found that radiators were also important, i have a 289 that started to overheat on the highway so i changed the head gaskets three times in one week thinking that was the problem, i ran my hand across the rad and the fins turned to dust, changed the rad and problem solved, my dad bought a dodge car and it was set up for towing a trailer and he went on a trip and it cost him over a thousand dollars to have his engine fixed because of overheating, when he got home i changed his rad and he never had a problem again, cooling is so important along with regular oil changes that most take for granted. i love people like you that do these type of videos for do it yourselfers like me.
Absolutely perfect Video.. Being a 20+yr mechanic the first thing I do is go get a radiator cap and fully flush the cooling system the day I buy a Ford .. and I always tell my customers I will not diagnose any cooling problems until it's been done on ANY vehicle as I have seen too many gm vehicles with the exact same cap on them.
hi Bill, love the videos, tons of info sharing here. I relate so much to many of your videos. I have a 2002 7.3l, 6 inch lift with 40 in tires, 3.73 gears. I'm on my 4th transmission and recently 2nd motor due to the Coolant bottle having Crack in it. I was 20 when I bought the truck and have been learning the hard/expensive way. everyone is quick to take my money but lack the knowledge and or professionalism to help me solve root problems. thanks for taking the time to create so many informative videos! not once did someone say you should change your gearing to stop eating transmissions, just install a new one, tell me everything's all good, then I'm back in the shop 2 years later, they love me. even the cracked Coolant bottle, they replaced the motor but never replaced the bottle, setting me up for another engine failure. I'm from bc canada and it just seems like a lot of guys lack the specific knowledge to work on my truck. maybe one day I can road tripper down and have a bulletproof done! thanks again, cheers!
Aha another smart man ...some people just don't think of the main cheap easy updates.. all these car dealerships are not here to save us money they want to do the maintenance in the rebuilding on our trucks...thanks Ron....)
Its not just Ford trucks . Its basically screw on caps for all manufacturers that use that style cap . I have changed many even on GM small cars . It seems the radiator cap is the most visible & yet the most neglected item under the hood . Just last week someone asked why is my upper hose collapsed ? I said, radiator cap & they looked at me like I was an idiot . I took off the cap & showed them the deformed rubber seal & reccommended a new cap . Good video good advise !
IT IS IMPORTANT ON ANY VEHICLE WITH A COOLING SYSTEM FOR THE CAP TO WORK CORRECTLY. The 7.3 does not generally make as much heat as the 6.0 so it is less of a problem.
Just wanted to thank u for the help as soon as the vid was over I went next door to the auto parts store an paid $5.70 for my cap. Thanks for the great vid an all the great help!
It's like you were in the truck when we were towing up the grade out of Needles, CA and the fan clutch went out and engine overheated. That $5 cap was $3K in repairs while stranded in Havasu! Fan clutch, new turbo unit, hoses, labor.....1 Ford dealer on a Holiday weekend. Great videos, thanks!
Less of an issue because the 7.3 doesn't run at as high temperatures. But it is a good idea to check the cap, there is no excuse for having a poorly working coolant system on any vehicle.
Man u r so unbelievably right when I get a vehicle I always replace all the caps no matter if they look new or not so I give u 4 thumbs up bro good lookin out for everyone thanks for being such a cool cat later.
@JustJoshinY It should be OK. Just drain the gas and fill with diesel. Put a quart of trans fluid in fuel. It may run rough for a while. Run it almost empty before filling up again.
@gbh559 Yes there is a lot of confusion surrounding coolant. It seems like every time there is some management change at Ford they HAVE to change the coolant. But physics of water and glycol will never bend to the will of a corporate committee.
Thanks Bill, I'm brand new to the diesel world. I bought a 08' F250 with 127,000 on it, a month ago, and read some stuff on the coolant and fuel filters. So had them both change last week, and tomorrow I'm heading to down to get a new coolant cap. I'm glad I've found this on youtube. Thanks again.
Thanks for the vid. I was having some issues with my 6.0 overheating while pulling a trailer and four-wheel, and ascending a hill. Put the new cap on, and the issue went away.
Thank you I will get one today I try to watch all your videos this is not the first video of yours that has helped me if my truck breaks I am bringing her to your shop
As a non-trained mechanic, woman, I liked the simplicity of this video. There's a lot I can't do on these new diesels, but I believe I can change a cap. I completely get it. I'm down for it thx.
@RyanDamo Cooler failure and radiator failure are two different issues. The radiators are faulty, the plastic simply gives under the pressure. The cooler failure is not from the coolant pressure. The failure is that the coolant is boiling at a low temperature due to lack of pressurization. SO the opposite is true. A working cap will SAVE the cooler.
I love your videos and appreciate what you're doing on your channel! With advice from "everybody and their mother", we bought a 2007 F250 6.0 Diesel XLT for our small remodeling business. So, I've been on a mission to learn what I can to be a good owner, and take this truck to 500K, if possible. We're fairly sure the previous owners didn't do much for the truck. We bought low, and will get this baby whipped into shape!
Great vid man! I'm not a Ford guy, but I've heard all the trash talk bout the 6 liter. You spoke very well, clear, no flubs! I wish I was that smooth. I'll mention your advice in my vids. Later... Andrew
good vid. i been say it for years. its the 1st thing i check when a car comes in.. has it got pressure.. never want engine at running temp with no pressure. with alloy heads its real bad. as soon as a boil happens you get steam pockets in high spots and then it can cause cracking. good to see you do this vid before you go into summer.
South bend clutch is the best conversion and worth every dime. The intercooler is a waste of time without addressing the crappy fuel pump. Unless you have converted to a electric fuel pump and regulated return, you will see little or no benefit from the intercooler system.
I put my new slant cap on today. Last little trip I made to Nashville, I came back home and raised the hood just to check coolant level and I could hear air leaking from the factory cap right after I turned motor off, so I'm gonna see how the slant does. Thanks Bill!
With the vast availability of aftermarket parts we get caught up in. We often forget the most important maintenance parts that keep our vehicles running. Thank you for this video.
@VIheavyequipment It sounds like a tired High Pressure Pump. But before I changed it I would remove the valve covers and run the engine to see if there is any oil leakage around the injector seals. You may just need to reseal the injectors.
im a gas truck guy, but a mechanic none the less, n u rock, most mech's arent like u n me, i love the numbers, the calculations, the science, the theorycrafting.
Well done Bill. Now you should do one on flushing and changing coolant. The old 7.3's running on green coolant actually required coolant additives that no one ever used. Ford later 2002 went to Premium Gold. No additives required. Now there using the Specialty Orange again, which is Ford version of DEXCOOL. in some engines. Coolant like oil and transfluid, DOES HAVE A SERVICE REQUIREMENT. People think, "Its filled for life" WRONG!!!
This is a great video. I watched it several times. I went and bought a new cap for my Powerstroke within 1/2 hour of watching it for the first time. Thanks for making it.
Possibly but more than likely the head gaskets are on the way out.The whooshing under the hood at speed is the cooling fan being kicked on and off in an effort to keep the engine cool. be careful not to burn up the engine. It only gets more expensive.
Not necessarily. First of all the gauge is crap. Second the overheating event is happening deep in the motor and the heat may have not circulated to the sending unit while pressure is being pushed out the cap.
Thank you for this info. I would bet a a dollar you’re right about why the head gaskets fail on the 6.0. I will be getting a new cap TODAY. Excellent video!
This guy is very smart when it comes to power strokes! Just had my fiancé watch this with me. We Subscribed. So fortunate to have this man sharing his mechanical intelligence with everyone!! 😀
This may seem simple to some People, But this Man is trying to teach you the simple things that can cause may problems. THANK YOU. FOR THIS BEING HONEST.
You have to appreciate a man that goes on the internet and gives out free advice to save you money at the cost of taking business from himself. Luckily there's quite a few people that ignore said advice.
@BuhlzI doubtful, I'd check everything very close on TOP of the engine especially around the oil cooler. The coolant will very often leak on top and flow down the back of the motor.
I hear ya Bill!!! The last several hundreds of coolant caps I've pressure tested on Ford, Dodge, Chevy, and many others have been total trash. It's clear that their suppliers have let them (an us) all down. The majority of caps are somewhat functional, but are typically functioning below their specified pop-off pressures by 3 to 4 psi. However, there have been many that have been totally worthless as well. It seems that modern vehicles are built so poorly, with inferior products. It's really sad. At one point I even checked my tester to make sure that it was still working correctly because it seemed unrealistic for such a high failure rate. Turns out, my pressure tester is perfectly fine and functional, but the vast majority of vehicle coolant caps really are absolute garbage.
It actually brings as much business than we can keep up with. There are over 4 million PSDs built from 94 to present. There is no way I can touch them all.
Low coolant pressures cause coolant to boil close to 212 F.. Nucleate boiling is happening in the cylinder heads near the exhaust valve jacket without system pressures in the 16psi to 19psi range.. This condition allows very high temperatures and cylinder head distortion, combustion destruction of the head gasket by clamping pressure reduction and then the fire rings burn out. When nucleate boiling is going on there is no cooling in that area and the rapid expansion of the coolant turning to steam is pushing liquid coolant away causing more over heat . Using a non H2O mix coolant will help .
Thats all fine IF you are not loading the engine. These later model engines like the 6.0 or 6.4 will push the coolant out of the system if they are not pressurized.
I'm so glad you posted this video! I just put in a new thermostat and did a coolant flush like you've showed. I just noticed two days ago that there is residue from the evaporated coolant around the coolant cap. I'm getting my new coolant cap TODAY!!!!
Every design has its strengths and weaknesses. I don't know much about dodge or chevy because I don't work on them. The newer models of all these trucks have a fit and finish that far exceeds the older models. Quieter, more powerful, and much much cleaner.
@Backwardsboi24 EVERY vehicle that has a pressurized coolant system needs the cap checked and replaced if faulty. The 6.0s and 6.4s were just more prone to failure,
Hi Bill I just came across your videos and immidietly subscribed, and I rarely subscribe to anything. Your videos are VERY helpful and I really appreciate the way you explain the procedures so thoroughly for those of us who have limited knowledge of these diesels. I'd like to say thanks and let you know that you are helping people with your videos. Jason from Arkansas.
I love your videos. As a new 6.0 powerstroke owner your videos are gold! Thank you. If i can ever afford to bullit proof my truck ill be bringing it to you! Mine is stock and the only mod is the blue spring. God bless.
Thanks for the tip... I noticed a cracked Coolant reservoir so I ordered the Dorman OEM replacement with NEW CAP from Amazon and installed it with PEAK 50/50 in my 02 F250 w. 7.3. I don't wanna end up in a diesel shop over a $50 fix!
Thank you for this channel! Bill is my go to guy for answers on my 6.7 powerstroke. Bill!, If you are listening. If I need heavy engine work, I will be bringing it to you sir. I consider you #1 in powerstroke knowledge. (Along with your sidekick of course) Amazing!
Just bought my first diesel since owning a POS 6.2L Detroit Diesel 30 years ago. I am now a proud owner of a 7.3L powerstoke I stole for $8,200!! Thanks for your videos.
Its true. The main reason they replaced the cap besides what you stated is that the old style warns the drive by whistling when cooling system holding pressure is exceeded. The new style cap doesn't whistle but makes more of a soft initial pop noise along with a hiss that can barely be heard when under WOT as opposed to the old factory style. This allows the driver to operate the truck longer with blown head gaskets or leaking EGR cooler without knowing until you're out of warranty. LOL.
Just noticed that my coolant reservoir on my 02 7.3 was empty after towing my new fifth wheel for the first time. I saw the coolant at the top of the lower tube though, so I figured I had a crack in the reservoir. After inspecting it I didn't see any cracks...further research led me to your excellent video and I ran right over to Advance for a gallon of 50/50 and a new coolant cap. So far so good, but I will keep a close eye on the coolant level. Thanks for posting this video, I believe that you saved me some dollars!
Your videos are outstanding,I'm getting ready to buy a 2004 250 6.0 And you have help a lot with your videos. I've never own a diesel just the Ford 150.The 2004 and 2005. I've always like. The 2004 I'm buying used to belong to my grandfather so looking forward. to fixing it up it has 183000 miles on it the body is good and run good so I just want to keep that way. Once again Thank for your help. Tim Lee from Lexington Ky.
It has nothing to do with the HPOP. You need to replace the Low pressure pump behind the lower belt pulley. The oil is bleeding back because the tolerances are too big. Melling makes the best unit.
I appreciate these videos... I have been planning on getting a diesel truck. I really started liking the idea a few months ago, and came across a video about the 6.4 stating the problems.. so I started to dig into the issue... thanks. I had even bid on on a Ford F-250 with. 6.4... I lost the bid thankfully... I won’t be towing really heavy loads... and I’m not into increasing the horse power massively... I will be towing a trailer jetter.. once or twice a week, locally, it’s a pressure washer basically, with a 200 gallon tank.. I just want a good truck, and I see lots of deals on the 6.4 .. all the others are twice as much...it’s scary to know you could spend 15k on a used older 6.4 and think you got a deal, only to have to spend that much again to fix it... I would not have known without these videos
Little details make a big difference, no matter what subject you want to consider in life. It's amazing how many people ignore the little details and how often. I'm guilty also. Thanks for bringing a seemingly little detail to our attention.

good vid. i been say it for years. its the 1st thing i check when a car comes in.. has it got pressure.. never want engine at running temp with no pressure. with alloy heads its real bad. as soon as a boil happens you get steam pockets in high spots and then it can cause cracking. good to see you do this vid before you go into summer.
South bend clutch is the best conversion and worth every dime. The intercooler is a waste of time without addressing the crappy fuel pump. Unless you have converted to a electric fuel pump and regulated return, you will see little or no benefit from the intercooler system.
When every I have issues this is my go to guy. I always check his videos before I do anything to my truck.
I put my new slant cap on today. Last little trip I made to Nashville, I came back home and raised the hood just to check coolant level and I could hear air leaking from the factory cap right after I turned motor off, so I'm gonna see how the slant does. Thanks Bill!
With the vast availability of aftermarket parts we get caught up in. We often forget the most important maintenance parts that keep our vehicles running. Thank you for this video.
@VIheavyequipment It sounds like a tired High Pressure Pump. But before I changed it I would remove the valve covers and run the engine to see if there is any oil leakage around the injector seals. You may just need to reseal the injectors.
im a gas truck guy, but a mechanic none the less, n u rock, most mech's arent like u n me, i love the numbers, the calculations, the science, the theorycrafting.
I have driven one that a customer brought by. HUGE power. Got to have the transmission to back it up.
Well done Bill. Now you should do one on flushing and changing coolant. The old 7.3's running on green coolant actually required coolant additives that no one ever used. Ford later 2002 went to Premium Gold. No additives required. Now there using the Specialty Orange again, which is Ford version of DEXCOOL. in some engines. Coolant like oil and transfluid, DOES HAVE A SERVICE REQUIREMENT. People think, "Its filled for life" WRONG!!!
As a New 6.7 Power Stroke Diesel owner - I'm grateful you make these videos, and I found them. Thanks! Gregg
Gregg Powell how is your truck doing ? I have a '16 6.7 and wondering if I should do the same
you sir are a Powerstroke God I have a 2002 F250 7.3 liter diesel 141000 miles on it unmolested with all your videos that truck will run forever
This is a great video. I watched it several times. I went and bought a new cap for my Powerstroke within 1/2 hour of watching it for the first time. Thanks for making it.
If I am not mistaken depending on altitude, boiling point should be between 145F and 150F.
This guy rocks. He is the Powerstroke Guru. Thanx for all of your great info over the years.
@cumminsbayou ANY VEHICLE with a closed cooling system is affected by a bad coolant cap. The problem is acute in a 6.0/6.4 PowerStroke.
Possibly but more than likely the head gaskets are on the way out.The whooshing under the hood at speed is the cooling fan being kicked on and off in an effort to keep the engine cool. be careful not to burn up the engine. It only gets more expensive.
This is like a V8 drink commercial, thank you for sharing!
after watching a few of his talks on a powerstroke... i subscribed .. i just got a 7.3 1997 f350 and it needs work so anything i need i watch this guy
Not necessarily. First of all the gauge is crap. Second the overheating event is happening deep in the motor and the heat may have not circulated to the sending unit while pressure is being pushed out the cap.
Thank you for this info. I would bet a a dollar you’re right about why the head gaskets fail on the 6.0. I will be getting a new cap TODAY. Excellent video!
This guy is very smart when it comes to power strokes! Just had my fiancé watch this with me. We Subscribed. So fortunate to have this man sharing his mechanical intelligence with everyone!! 😀
5:57 Five second pause to absorb the concept. Nice! I like the look on your face during that time. It's like, "Now you're getting it!" WELL DONE!
This may seem simple to some People, But this Man is trying to teach you the simple things that can cause may problems. THANK YOU. FOR THIS BEING HONEST.
You my sir are why I decided to buy my '06 Power-stroke and I put this cap on before I made it home with the truck.
This is legendary i award you 10 billion points for your vast knowledge.
You have to appreciate a man that goes on the internet and gives out free advice to save you money at the cost of taking business from himself. Luckily there's quite a few people that ignore said advice.
Ive been watchin your videos for a while now and I didnt even know it was possible for someone to know as much as you do. Your videos are awesome!
@BuhlzI doubtful, I'd check everything very close on TOP of the engine especially around the oil cooler. The coolant will very often leak on top and flow down the back of the motor.
I hear ya Bill!!! The last several hundreds of coolant caps I've pressure tested on Ford, Dodge, Chevy, and many others have been total trash. It's clear that their suppliers have let them (an us) all down. The majority of caps are somewhat functional, but are typically functioning below their specified pop-off pressures by 3 to 4 psi. However, there have been many that have been totally worthless as well. It seems that modern vehicles are built so poorly, with inferior products. It's really sad. At one point I even checked my tester to make sure that it was still working correctly because it seemed unrealistic for such a high failure rate. Turns out, my pressure tester is perfectly fine and functional, but the vast majority of vehicle coolant caps really are absolute garbage.
Bill the Powerstroke Preacher. I remember watching this video years ago. Probably 2014. I was blown away. He is an absolute genius.
bill i can not tell you how much i appreciate the fact that u exist brother....thank u
It actually brings as much business than we can keep up with. There are over 4 million PSDs built from 94 to present. There is no way I can touch them all.
Real quick wanna say thanks man for all your insight and technical support. I do appreciate it. Thank you again
Low coolant pressures cause coolant to boil close to 212 F.. Nucleate boiling is happening in the cylinder heads near the exhaust valve jacket without system pressures in the 16psi to 19psi range.. This condition allows very high temperatures and cylinder head distortion, combustion destruction of the head gasket by clamping pressure reduction and then the fire rings burn out. When nucleate boiling is going on there is no cooling in that area and the rapid expansion of the coolant turning to steam is pushing liquid coolant away causing more over heat . Using a non H2O mix coolant will help .
anonov1
Thats all fine IF you are not loading the engine. These later model engines like the 6.0 or 6.4 will push the coolant out of the system if they are not pressurized.
I'm so glad you posted this video! I just put in a new thermostat and did a coolant flush like you've showed. I just noticed two days ago that there is residue from the evaporated coolant around the coolant cap. I'm getting my new coolant cap TODAY!!!!
Every design has its strengths and weaknesses. I don't know much about dodge or chevy because I don't work on them. The newer models of all these trucks have a fit and finish that far exceeds the older models. Quieter, more powerful, and much much cleaner.
Still rocking my 07 6.0 all over the continental us thanks to this guys videos. Good truck.
@Backwardsboi24 EVERY vehicle that has a pressurized coolant system needs the cap checked and replaced if faulty. The 6.0s and 6.4s were just more prone to failure,
Hi Bill I just came across your videos and immidietly subscribed, and I rarely subscribe to anything. Your videos are VERY helpful and I really appreciate the way you explain the procedures so thoroughly for those of us who have limited knowledge of these diesels. I'd like to say thanks and let you know that you are helping people with your videos. Jason from Arkansas.
@kyfordfan You need to test the cap and make sure it is releasing at 15-16 psi.
Thanks Bill. Just bought my first Diesel and am as knowledgeable as a 9 year old girl. Getting educated. Thanks!
@VIheavyequipment Yes the Coolant flush procedure is the same pretty much for all vehicles.
I love your videos. As a new 6.0 powerstroke owner your videos are gold! Thank you. If i can ever afford to bullit proof my truck ill be bringing it to you! Mine is stock and the only mod is the blue spring. God bless.
BEST CHANNEL ON UA-cam HANDS DOWN! I will drive 500mi the second I need work! Keep the videos coming!
Thanks for the tip... I noticed a cracked Coolant reservoir so I ordered the Dorman OEM replacement with NEW CAP from Amazon and installed it with PEAK 50/50 in my 02 F250 w. 7.3. I don't wanna end up in a diesel shop over a $50 fix!
Thank you for this channel! Bill is my go to guy for answers on my 6.7 powerstroke.
Bill!, If you are listening. If I need heavy engine work, I will be bringing it to you sir. I consider you #1 in powerstroke knowledge. (Along with your sidekick of course)
Amazing!
The best video and advice I have heard on power strokes, and I have been messing with them for a while.
Just bought my first diesel since owning a POS 6.2L Detroit Diesel 30 years ago. I am now a proud owner of a 7.3L powerstoke I stole for $8,200!! Thanks for your videos.
Its true. The main reason they replaced the cap besides what you stated is that the old style warns the drive by whistling when cooling system holding pressure is exceeded. The new style cap doesn't whistle but makes more of a soft initial pop noise along with a hiss that can barely be heard when under WOT as opposed to the old factory style. This allows the driver to operate the truck longer with blown head gaskets or leaking EGR cooler without knowing until you're out of warranty. LOL.
Just noticed that my coolant reservoir on my 02 7.3 was empty after towing my new fifth wheel for the first time. I saw the coolant at the top of the lower tube though, so I figured I had a crack in the reservoir. After inspecting it I didn't see any cracks...further research led me to your excellent video and I ran right over to Advance for a gallon of 50/50 and a new coolant cap. So far so good, but I will keep a close eye on the coolant level. Thanks for posting this video, I believe that you saved me some dollars!
Subscribed, I love the enthusiasm he has for his trade and how knowledgeable he is when it comes to these trucks.
Your videos are outstanding,I'm getting ready to buy a 2004 250 6.0 And you have help a lot with your videos. I've never own a diesel just the Ford 150.The 2004 and 2005. I've always like. The 2004 I'm buying used to belong to my grandfather so looking forward. to fixing it up it has 183000 miles on it the body is good and run good so I just want to keep that way. Once again Thank for your help. Tim Lee from Lexington Ky.
They mustve sold a ton of them after this video.. they are $13.00 now lol
$2.52 at Walmart 10238 16psi; Nov 2019
MrGGPRI it’s the same part he is telling us about?
Not where I buy them. Lol
$7 and some change advance auto
I’ve tested 4 in store that won’t hold 16. Two held 0 and two won’t hold over 10.
It has nothing to do with the HPOP. You need to replace the Low pressure pump behind the lower belt pulley. The oil is bleeding back because the tolerances are too big. Melling makes the best unit.
I appreciate these videos... I have been planning on getting a diesel truck. I really started liking the idea a few months ago, and came across a video about the 6.4 stating the problems.. so I started to dig into the issue... thanks. I had even bid on on a Ford F-250 with. 6.4... I lost the bid thankfully... I won’t be towing really heavy loads... and I’m not into increasing the horse power massively... I will be towing a trailer jetter.. once or twice a week, locally, it’s a pressure washer basically, with a 200 gallon tank.. I just want a good truck, and I see lots of deals on the 6.4 .. all the others are twice as much...it’s scary to know you could spend 15k on a used older 6.4 and think you got a deal, only to have to spend that much again to fix it... I would not have known without these videos
Little details make a big difference, no matter what subject you want to consider in life. It's amazing how many people ignore the little details and how often. I'm guilty also. Thanks for bringing a seemingly little detail to our attention.
