- This is an in-depth of how to diagnose excess pressure build up in your cooling system. This gives a general idea of everything that can be the cause of the issue and steps you can take to pin point what your true issue is which in turn will eliminate a lot of time wasted and money getting to the bottom of the issue. Bear in mind I'm not a mechanic but willing to work on my own truck and these where my findings that my air compressor was bad. #headgasket #egrcooler #aircompressor

My man, thank you for your videos. They save us so much money.
This is a much more informative video than 90% of mechanic videos out there on how to narrow over pressure down
Damn I appreciate that!
Very helpful, i thought i had a blown head gasket until i watched this science video. Enjoying your content brother again very useful.
I’m glad the videos are helping 🙏👍
You know, if you had taken your truck to a shop, they would have told you exactly that, just to make more money.
@LEGEND04131 Mine ended up being the air compressor, actually.
Hello Sir ! I just wanted to thank you for your knowledge ! I watch your videos when I have a problem like you and I find that you are pretty darn smart ! So with that being said I subscribe to your channel and gave you a thumbs up ! Thank You so very much for all your videos and may you have a wonderful blessed day Sir!
I appreciate this so much cuz honestly it motivates me in a big way because I myself is trucking and I always think these videos aren’t helping anyone. So again thank you and Just Keep Trucking!!! ✌️🫡
Well I really appreciate what you do and to be honest I’ve been watching your videos a lot because when I have a problem with my Truck I go to your page and see if that was something that you had worked on !! lol ! But for real thank you again for all you do for us drivers that appreciate someone like you !! God bless you my friend and keep Trucking 🙏🙏🙏✝️
@@lauriemckernan7369 Thank you for the support and comments like these makes me want to share and help as much as I can when I encounter an issue and resolve it. Thank you for watching and Just Keep Trucking!!!
This is my last hope, I have been to several repair shops, some said there is no problem, some said the head gasket and asked me to go to the dealer for engine repair. But I don't think so because I have driven more than 1000 miles since the problem appeared, and there has been no change in the oil. The power has not decreased. Recently a mechanic replaced the expansion tank, but the problem remains. When I said the air compressor all the mechanics said that the air compressor is working well and does not need to be replaced. Thanks for sharing brother. I really don't have money for engine repair
There are multiple test to see if your compressor is bad and the main one is.
1. With your hood open, take off your overflow reservoir tank cover
2. Bleed your air tanks to 0 or empty
3. Whilst looking at your overflow reservoir, start truck and let air pressure build
4. If coolants starts to rise and even overflows, your air compressor is pressurizing your coolant system. Turn your truck off and then you’ll know what your specific issue is.
5. You can also use a clean rag or paper towel around mid section of truck where your air dryer is and if it blows off excess air into the towel and it’s not clear but same color as your coolant, your air compressor is the issue.
Great video!! especially the example of the exhaust gas test. Excellent process of elimination!
I appreciate it. Imma just try and record as much as I can. Just Keep Trucking!!!
Oil will not always be creamy when a head gasket blows, it requires that the gasket blows between a oil and coolant jack which isn’t common, when a head gasket blows on a paccar it actually has a weep hole built into the head gasket will that build up and will leak behind the turbo indicating a blown head gasket
@@Heated_Diesel Thata sone good information. Appreciate it
Much blessings and always thankful for your help. U did a video on the air dryer filter and purge valve. I went ahead and attached mine because it was showing signs of needing maintenance. Let me just say damn!!!! It was embarrassing to see the build up of crap. In the end, everything turned out looking good. All systems back on track and working perfectly. Much thanks, Bredrin 🙏🏾🙏🏾
It’s always a good thing when I see that my videos helped someone cuz there aren’t a lot of helpful videos. Thank you for watching and Just Keep Trucking!!! 🫡👍
Another great video brother. Kept it up. When these engines get so many Mike's on them, it's just one thing after the other isn't it...
Stay safe brother!
Once that odometer hit 520k miles, it’s been pick and pull 😂🤣😅
Thank you my brother. Good video & very good explanation.
Thank you I appreciate it 🙏✌️👍
Thanks
No Problem.
Really good work,I'm learning a lot from this guy,thank you
That’s awesome and I’m glad it helped. Just Keep Trucking!!!!
Well done! Very informative video! Had this problem with my paccar 2018 close 650k miles. Did install coolant hoses, flush coolant, changed coolant thermostat and new radiator due to the nipple hose cracking. Will test the air compressor! Thanks again.
There will be tell tale signs for example if you go to your purge valve and there’s coolant coming from it when it purges.
@@dentrizzleim check that today! Thanks
@@dentrizzle I’m having same problem now, dealer wants to spend 6-9 hours to find the problem. I don’t want to spend too much labor for nothing. I want to cut down the chase. lol did you air compressor have problem with air previously or it was working normal? Mine is working fine, but maybe just minor problem that cause the pressure to coolant. How much did they charge you to replace labor and new compressor
@@isseacn Air compressor worked fine. Coolant system was being pressurized and it will be obvious with coolant literally blowing out of the system and also every time I stop the low coolant light would chime. I didn’t pay labor nor anything because I had replaced it myself. There’s a video on my channel. Hold this helps.
I check the purge valve, it feel slippery but clear water. Does that mean coolant is in it. Thanks 🙏🏾
My Renault truck (10tonne) keeps blowing the head gasket.
What could be the problem?
O
From what I’ve learned most blown head gasket is due to overheating. This would also caused the head and block to warp so they have the machine both to get a flat surface. If they are warp and they keep replacing head gasket, it will break again. This is all I know. Hope it helps.
If the block has a crack , would I need to buy a new one ,or can it be repaired?
Am in Zimbabwe
Or a dropped liner@@dentrizzle
@@kingjames7273 yeah that’s what I found out as well. Even a cracked cylinder head. Too much variables in all honesty.
Amazing research.
@@salvadornevarez7934 I Appreciate It!!!
Great detective work there my friend.
@@winginitwithjohn8451 thank you I appreciate it!
Love the video. Thanks, keep the content coming
More to come 😅
Awesome video, nice to add to my knowledge base!
I appreciate it. Just Keep Trucking!!!
Hey my friend, I have a low coolant light and stop message appear on dash but coolant level is fine. Sensor and reservoir tank have been changed. No leaks. What could it be? Only comes on when running up hill but sometimes goes off before I even pull over.
Had those symptoms and that’s when my air compressor went out.
Have the same problem now. Already replaced thermostat, water pump, and radiator. I guess from the pressure. Truck is not running hot at all and I see no signs of coolant on dipstick or oil. It’s using coolant and pushing out. Recently I have to add coolant as there’s a leak somewhere. Could the compressor be using coolant. What do you think?
Thanks for your videos. Learned a lot in your videos.
That was also some of the symptoms of a bad air compressor when mine was bad. The compressor actually pushing coolant through your air system. You should see it where your air blows off around the back.
Im doing those tests, today. I've been having to buy coolant. Since I left texas, to Cali. Where did you get that tool?
It’s called a head gasket leak kit which you can get at any parts store.
Thanks brother I don’t know maybe I am also facing same problem.thanks a lot brother
Ok no problem. If there’s coolant at your air dryer is your air compressor.
Hey like your videos. Have helped me a few times already.
Hey did you just replace the compressor gasket or did you replace the whole compressor
@@johnrkrahn5827 I’ve replaced the entire air compressor
I do have the same issue coolant was blowing out of the relief valve sometimes. Also when I fill in the reservoir and go down hill I get check engine light on and low coolant light. As soon as open the reservoir cap it comes back to normal level. Do you think it’s the same issue?
There’s a possibility because what you explained were the very same symptoms I had. Got to check it out or let someone check. This video may help.
I dropped the truck off at Kenworth today. Hopefully they will be able to fix the issue.
@@alwaleedabdullah5153 Did they got your truck fixed up already???
Did they find your issue yet?
@@alwaleedabdullah5153did they fix the issue if so what was it ?
Did you replace compresor?
Did it fix the problem?
Yes I did and everything was fixed. I have a video on my channel for reference.
ruclips.net/video/gLVwu7MrSS4/видео.htmlsi=0Q5N1bf0kSFsn9Xs
How is a failing water pump or thermostats not something to check?
Because I wasn’t having overheating issues. Coolant was pushing out of the relief valve so some sort of pressure was introduced into to cooling system. Thanks for watching 👍
I've got a d13 engine with overheating issues. Changed waterpump and thermostat. Had pressure coming out overflow as well. Changing compressor now for my last option. If not back to company driving I go
@@jaynorris21 I know how much that must sucks but usually there are tell tale signs leading to the main issue. I would check thou.
I think you saved me some money today
That’s what I like to hear comparing to others tearing me down in the comments. Thank you!!! 🙏
Thanks bro! Very helpful!
I’m glad it helped you. Just Keep Trucking!!!
Thank you Sir❤
No Problem 👍
Good video well detailed 💪🏿💪🏿💪🏿
@@heavypressureinc Thank You 🙏
Thank you
Your Welcome 🙏
I'm having this same issue. My coolant cap is all creamy. But i have no cream in my oil
A component with oil may be the issue. I would look at your air compressor
Im having the same issue…why can you just replace the air compressor head and gasket (the top part of air compressor)?
I think you can as long as you get it inspected and it’s actually the gasket that’s broken or something like that. At the time when I discovered my issue I just replaced it cuz I was cut against time and it was my first time.
Oh ok thanks very helpful info I appreciate it…
@@pedroquijada6818 No Problem
@@dentrizzlewhat was the problem with your truck? Was it the compressor that was bad ?
@@isseacn it was the air compressor head that was bad but I went and replace the entire thing. Haven’t had the problem since.
I noticed the water seperator filter was creamy white.
Sometimes they are like that cuz diesel is oily based and it separates water and when they mix it’s a lil bit creamy hence we have to check our filters out and replace. Your keen to observe, I like that 🫡
Thanks for your video
@@ynadsuyanolacse995 Your Welcome
My 2020 pete 579 was low trans air every so often yesterday while driving wrench light came on and truck immediately shut off like 5 seconds after light i pulled off road truck will crank veey well but not start had to get towed. Call peterbilt 800 number they say egr low pressure code..waiting on dealer to check monday...any thoughts
@@bronxbredboxtruckerb7521 I would have used my scan tool and figured it out from there. Crank no start can be several things like not enough fuel, bad unit pump, air entering fuel system or even fuel filters are clogged.
Called Pete hot line Saturday was told that earlier wasn't circulating on 1 code then another code that it was closed still waiting to hear from dealer with their diagnosis
Eerlier= ECR
@@bronxbredboxtruckerb7521 did you get a diagnosis???
@@dentrizzle truck is at peterbilt being told today truck will be diagnosed unreal how they take so long to read codes at dealer
Great video brother. I am on process buying a Peterbilt or T680 with Paccar engine. So far how is the MX13 performing on your truck? About mileage per gallon? Any big issues?
Thank you for sharing this information.
Cheers from Calgary, Canada 🇨🇦
@@WolfNathan All in all it’s has been a pretty reliable motor no matter what you may see or hear others say as long as you keep up on maintenance “as you realize I do my own.” I have the Mx13 EPA 17 and it’s not the fastest or strongest but it gets the job done. A Freightliner Cascadia out pulls me every time up a mountain lol. The major problems for these are DPF and I haven’t had any except sensors which will eventually go bad on any vehicle. Again I maintain as I should. As in issues I record almost all of them on the channel and I wouldn’t say they are major problems but more common issues. All in all if you maintain the truck as you should it will last. Bought at 300k and now at 770k. I 👍would buy another Paccar. Mileage range from 5.8 to 7.4 at average 76k pounds depending on mountains or flat lands. Hope this epistle helps 🫡👍
@@dentrizzle I appreciate your reply. You are right, maintenance will be the key. I sold my Volvo with 1.3 million miles. All original, only replaced the Ishift clutch. I am a little bit skeptical about the Cummins or Detroit. Last week I was working with a Peterbilt with a Paccar 510, pulling a B-train tank, I was impressed with the performance.
Thanks again…

@@dentrizzle u seems like a big mechanic me genna....what u thing about the paccar vs cummins x15?
@@dweettbigg8422 Both are good engines and both will have flaws. I’ve never driven the X15 but heard they’re real good and most ppl swap the paccar to the X15. Been driving paccar since 2019 and I don’t mind it at all. It’s a very lazy engine but it gets the job done. Heard X15 pulls way stronger and faster. Freightliner out pulls me every time 😂😂😂😂
@@dentrizzle ohh kl lol.....once you know how to work on it you good
I'm having the same problem RIGHT NOW
A good diagnostic can help save you the big worry
Did you find out the problem

My kenworth is have the same problem, how much did you get the air compressor for?
Think it was like $4000 give or take but I had to drive like 20 hours total to get it that cheap. They are overpriced at the moment due to back order.
@@dentrizzleI got lucky KW charged me 3000 CAD 1300CAD for the part and rest on labour
@@sanampreetbajwa2645 I think for that job they charge between 5-8 hours at $250 per hour at the dealership. I may be wrong but sometimes you have to take matters into your to your own hands. They didn’t have time to work on my truck so I just replaced it myself. Thanks for watching and Just Keep trucking!!!
@@dentrizzle you’re right they had my unit for almost 2 weeks there, you definitely saved time and money!
@@sanampreetbajwa2645 I do most repairs when I’m home on the weekends 🥲😁
Why you dug a hole in you exhaust pipe dude , im wondering if its just for the test😂.
No that’s how those Paccar exhaust are. Just check other trucks and you’ll see 😂😂😂😂
If the air compress was the problem shouldn’t it have some different asymptomatic like no fan running?
It was my air compressor because there was coolant in the air system. I already replaced that air compressor for some time now and the issue was fixed. I just haven't edited the video and posted it as yet.
@@dentrizzle did you have coolant coming from the intercooler tube?
@@A.M.E-K-87-10 no it was pushing out of the coolant relief valve.
@@dentrizzle I had something similar and did check my oil and nothing there… I think I’m having this problem because I over filed the coolant.
Hey bud, happy new year, there is anyway I can talk to you on the phone or fb messenger? I have something going on and we have the same engine, thank you

That's bro
I appreciate it!
paccar ?!
Yeah it’s a Paccar MX13 EPA 17
I have the same issue replaced egr
Next month replaced compressor the cap pressure
Truck work fine for few months them pressure on coolant again
Take to dealer open valve cover there was coolant inside engine the funny part the oil stick and cap no signs of coolant decide to rebuilt engine
I got lucky it was my air compressor. I replaced it and everything was back to normal but that air compressor was way too expensive than it should be. Demand and supply. I’ve video the removal and install. May edit it and post it so it may potentially help someone. Appreciate you watching.
@@dentrizzle definitely post it brother. That resilience of yours is contagious. I’m an owner with a MX also. It’s nice to see the content.
