Outstanding video! Very helpful for my students to see diagnostics and R&R in one video!

Glad this came in handy for you. Hopefully more content on this channel proves useful to you. Stay safe out there and keep grindin.

Always appreciate that positive feedback. Caught me offguard for a min there. I was thinking oh shoot people are actually watching me and to top it off learning something from me. It makes a huge difference when I actually hear it. I hope to continue videos again hopefully my content proves useful on your journey. Stay safe out there and thanks for reaching out.

Thanks for watching. If your driving and coolant temp doesn’t get past 185 than I’d be leaning towards a thermostat. If it gets to 200 and drops low randomly I’d be looking at the wiring/ garage/ or coolant temp sensors. Hope that helps.

Appreciate your support with the channel.

You'all all your shop partners'owners keepin real genuine with the people

Thanks for watching and reaching out. Means allot to me when I hear from you all. Thanks for the idea on the next video. Stay safe out there and keep grinding.

Thanks for your positive feedback. Exactly what I needed to hear to keep this channel going strong.

I appreciate you watching and your support. Unfortunately I’m at a dealer and they are way too expensive even for me.

Thanks for the positive feedback. Anything to help get the knowledge across and save money in the process. For now just through youtube.

Plz code spn 175 dd15 thanks

Great question and thanks for asking. Loss of coolant and nothing external let me down this path. Sometimes driver will complain of excessive smoke from the tailpipe but not always as the DPF seems to collect most of it. And a simple check inspection of the EGR crossover pipe and you’ll be able to see if there’s a lot of coolant passing through. Hope that helps

Thanks for reaching out and watching. If your loosing coolant the best thing to do is have the system tested under pressure. Never just assume it’s one part or another. And always ask to see the part intill you trust the shop just to build that relationship.

Hope it helps for future repairs.

@@bustedknucklebydieseldr3228 Actually ordering one for my 2015 cascadia dd15 right now.

@@AkashG334 thanks for reaching out. I usually don’t replace dpf filters intill after the repair, if the regen fails for high temps out of range. I warn the customer before hand it may come down to replacing them. But majority of the time they pass. The safest and most expensive bet is to replace them but I don’t like to over repair. And egr cooler is 4 hrs to replace and dpfs are 4 hrs as well. Of course this doesn’t include any diag. But parts pricing would be the huge amount here.

@@bustedknucklebydieseldr3228 This dealer charged 8 hours to replace EGR and then finished the work in 1 hour. We saw on the ELd that truck was ready in an hour

Absolutely, along with many other possible leaks. There are so many areas that could cause coolant leaks on these engines. But egr cooler failures are very common on both detroits and Cummins.

Great question and thanks for watching. Where the cooler mounts to either side pipes , one of those might not be lined up properly. Clamps may be secure and tight but if the pipes aren’t set perfect it’ll make that noise occur. I would go though and check all those first.

Great question. I’m normal operation you’ll get small traces of EGR in the cooling system. But sometime to much will go into the system and show itself on that surge tank. I would have you EGR cooler checked for internal leakage. If it passes than change your surge tank and put new coolant.

Great question, if it’s leaking external than I would just know for sure nothing else is leaking on to it. There a few hoses or fittings that usually leak on it and could look like the cooler is leaking. If it’s just the cooler, than there are companies that clean or repair them. Since the cost Isn’t to bad for a new one I usually just get new instead of that route.

Thanks for reaching out. When it comes to batteries becoming weak I would start with checking connections and for excessive resistance such as corrosion. Those will cause you many issues. All the other tests would need a multimeter to start checking alternator voltage and excessive draws on the truck. It helps to be handy with electrical for these tests.

Shhhh don’t tell KZfaq. Theyll shut it down.

If your truck has deleted EGR/aftertreatment than you can remove/block off that EGR cooler or lines. If it’s leaking plug it off as it’s not needed. They do make block of plates for all the ports of you do decide to remove the EGR components.

@@bustedknucklebydieseldr3228 so I’m in a little bit of a no where and was thinking of blocking it off with some aluminum from some energy drink will that melt. And Man U just save my ass thanks and do I need to drained the coolant? What I did was I notice once the coolant got low I bypass the sensor and it wasn’t leaking no more do you think coolant is low enough where I don’t need to drain it don’t have no where to drain it into. Again thank you so much.

Got that good motivation music.

Great question yes there is. Although I’m a little confused on the back pressure in the reservoir as there should be a good amount of pressure 18psi ish. sometimes it’s too full and it has to find a way to leak out to the ground. If there’s fuel in the coolant then I would consider testing the injector cups. And if there’s no EGR gas or fuel in there I wouldn’t worry about anything contaminating it. Hope that helps some

A lot of times excessive cooling system pressure will be caused by your air compressor very common in older trucks or your head gasket failed more common in newer trucks.

@@bustedknucklebydieseldr3228 the compressor IS new , so i think and Hope IS only head gasket, this morning with cold engine i open the tap and had Big pressure, spit all coolant

@@kepasakolegi8871 if ur engine was cold and you had that much pressure built up. I’m starting to think your pressure relief coolant pressure ports in your coolant reservoir is plugged. That pressure should be going down through there. So if it’s plugged it’ll never escape.

@@bustedknucklebydieseldr3228 thank you for your answers , truck IS in garaje and the issue IS head gasket.

Great question. In your surge tank there are extra pressure sections built in. Coolant will be kept on these sections and flow to the main area where the level is and cause the level to read correctly. I would fill coolant to max mark cold and not worry about it till you start loosing coolant. Great quest though and thanks for reaching out.

@@bustedknucklebydieseldr3228 thank you so much for replying!! I love your channel👍

I drain the coolant from the block and that was good enough. Once everything is loosened the cooler is kind of stuck on there so I use a prybar to pry it away from the block. Some coolant will come out of the cooler but not to much.

If you keep loosing coolant I’d pressure check the system and check everywhere. Even on dash floor or sleeper floor. Those heater core like to leak. If there is nothing external at all it’s will be going in either the exhaust or the oil.

Thanks for reaching man. I could Deff see where your coming from here. But you Gta remember cars, trucks and semi trucks all were made to recycle exhaust gas. These semi trucks take the EGR and use it to there advantage and great power out of it. The only downside to the entire system is the aftertreatment which as well all know always have some type of sensor issues. The engine itself runs great with a combined mixture of fresh air and recycled air which infact brings up the temps for combustion and create more power. So I believe they stayed away from an Eng side def filter because they used this current method to the engines benifit. Hopefully that doesn’t sound to confusing. But. To clear it up the Eng we made to run as powerful and as dirty as it can and it’ll just get cleaned later in the aftertreatment so there not worried about soot issues.

Also I’d give two thumbs up if I could because that’s a well thought out idea.

I'm going to give it a try by welding few parts together and use old def filter and let you know what are the readings and again you make some of the best videos out their ,man thanks

With a coolant leak they should be able to fix fairly quickly. Guessing where it’s coming from could lead us in so many directions so my best advise is take it to the ones who did the rebuild or a mechanic you trust to put the system under pressure and see where all the leaks are coming from. There might even be more we can’t see without being under pressure. Those are great year trucks and I hope it brings you no issues and lots of $$$ in return.

Great question. If your losing that much coolant and your certain there is nothing external. Than it will either be a leaking egr cooler back into your intake or a leaking head into your oil pan. Check your oil level and see if it’s to high.

Great question. Either something is cutting the hose causing it to leak or the clamps are crap, or clamps need better positioning on the pipe.

@@bustedknucklebydieseldr3228 thanks 🙏

Nothing about the dd13 is easy. Everything is so hard to get to and we all dread when one comes in.

@@bustedknucklebydieseldr3228 And the DEF pump heater lines are always brittle and need to be replaced at the same time.

Great question man. I’m actually a little confused myself. If the def system is eliminated than I’m assuming you have a custom tune to stop EGR system from being used. If that is infact the case than you can block off your EGR cooler just incase it starts to leak and pushes coolant into your intake like in this video. I think that may be what he means by pumping water. But save your money and find a block off for it, that would be the best bet.

Thanks for watching and reaching out. A diag computer will be needed for this troubleshooting. Basically you’d be checking sensors to see if there reading wrong. Than check for any intake or exh leaks. If that’s good it would take you to the turbo and run a few tests on it to see if it’s keeping up. A lot of the time I’m finding the turbo is the issue. Hope that helps some.

On a Dd13 the cooler comes in two models. One like this which will add about 3 hrs and one even bigger model that incorporates the egr coolant collector which needs the exh manifold to be removed. This one adds about 10 hrs. What a pain.

@@bustedknucklebydieseldr3228 yeah my entire fleet is short nosed DD13s everything is a bitch on them! I get jealous watching him work on all the 15s lol

I would say replace it once a year. That’s long enough and under may be to soon. At a year mark is just right.

Just pulled the hot pipe off. Didn't see any coolant but saw some leaking around the reservoir cap. Gonna try the $15 fix before I try the $1500 fix. Thanks for the video.

Thanks for watching and great question. You know I can’t honestly recommend going any longer losing that much coolant. It is quite a bit. A failed cooler won’t cause hydro lock but if you start noticing your oil level rising due to coolant contamination than I’d stop running it right away. Than you’ll get locked up. When I do drain the system I drain it from the block so most of the cooler would be empty upon removal. When you do go to remove it maybe a 2 liters worth will come out. Not much. If you don’t drain the system than expect around 3 gallons to come out. Being the highest point shouldn’t be much more than that. Failed coolers usually lead to coolant just being burnt up in the intake but long term effects will definitely weaken the valve seats and cylinders. So sooner the better. Hope that helps and thanks for your support on this channel.

@@lightningguy4897 What is the $15 fix?

@@anonymoustrucker1782 it ended up being the reservoir cap. Leaking and not holding the proper pressures. Just when I see coolant loss and it's not on the ground or not going in my oil pan my mind goes straight to worst case scenarios.

@@lightningguy4897 Gotcha. I think my egr is bad though. I have a code for egr pressure . And i am losing coolant, not leaking anywhere

I put a hat on and been in hiding in plain sight. Like Superman wearing his glasses , you can’t recognize him.

Well that would be very strange. That color would be oil getting into your exhaust unburnt. Shouldn’t happen with your heater , should be happening all the time.

@@bustedknucklebydieseldr3228 Thank you love your tips

I Gta say damn. That took initiative doing it at a rest area. A radiator is no quick and easy job. If your reservoir keeps getting low than for sure your leaking somewhere. Either external or internal. A quick check for internal would be checking the EGR crossover pipe going to your intake. If it’s really wet you most likely found your answer. If not wet than something on the outside is not sealing. Usually those radiator hoses don’t seal well after so many miles once touched.

@@bustedknucklebydieseldr3228 kzfaq.info/get/bejne/ip-nd9KAtJPZhY0.html

Thank you for your reply. I will be keeping an eye on my coolant and if I continue to loose, I will inspect the crossover pipe. Thank you for making your videos.

Well couple of options. If there’s coolant in the pipe than your cooler gave out. If it’s fuel than your injectors are failing open. If it’s oil than get ready for a big bill, could be a head issue. Smart thinking just towing it, don’t want to hurt it worse.

@@bustedknucklebydieseldr3228 had it towed to freightliner they inspected the oil and it has coolant in it , they told me cylinder 1 is damaged and the crankshaft is damaged and also couple of bearings and both mains also damaged ,my psi for oil was right under the 60/or 70 psi I took it to freightliner a month ago and did the pick up tube for oil before it went out my brothers trucks engine just went like that so I wanted to prevented it happening to me and they also did bearings and mains and also a adjustment on top of the engine I was wondering is there any way they could of caused the damage with their work something they didn’t do right and now a month later this happens to me , also the egr went out also ,any help would be appreciated I’m trying to see see if they caused it at all

@@Wolfci man oh man I’m sry to her that. So it could just be bad luck and it’s time to give out. Or. They could of not primed the oil system after they did the oil suction manifold and that caused the bearings on the crank to prematurely wear out. That would be very hard to prove though but Atleast you have some knowledge to combat them with if you were to bring that up. With the the of the truck they will most likely just say it’s time.

@@bustedknucklebydieseldr3228 I understand it’ll be hard to prove it , just wondering how the engine just damaged the new bearings and mains when I did both of them less then a month ago could cylinder 1 damage cause all of that damage with multiple bearings being damaged

@@Wolfci if cyl 1 was the failure than one of a few things could of happened with it. And I get that , but I don’t see why other bearings would of been affected unless something went wrong with install. You were smart and got them replaced as a precaution. I would Deff ask to speak with a shop mgr to open an investigation as you were being safe on ur part. The end result my be the tech that touched it last.

Great question, loosing coolant and not finding any external leaks. Excessive smoke out of exhaust. Coolant in the intake.

Pretty good question man. I would lean towards no because when the cooler leaks the coolant goes through the intake and gets burnt up with combustion and goes through to the exhaust. I bet there is a cold water leak somewhere, you would just need a pressure tester and let it sit. After some time it’s bound to show itself.

@@bustedknucklebydieseldr3228 hey man thanks for the reply! I been scratching my head over it so I guess I'll get it pressure tested.

Labor is usually 4 hrs for just this repair. But an oil change is recommended and a cooling system flush would be a good time.

Great question. Both those answers work because with cold water leaks the engine can’t be running and with hot water leaks Eng has to be running so depending on which kind of leak you end up with. And then you Gotta be careful looking at it and making sure it’s not just condensation but actually coolant in there.

@@bustedknucklebydieseldr3228 thank you.

If you deleted your EGR system/DEF system then you can go ahead and block off the EGR cooler and go ahead and take it off because that’s just extra weight you don’t need.

@@bustedknucklebydieseldr3228 You always helper thank you so much

If your interested I’m at a dealer group in az But you gta be ready for those dealer prices.

Thanks for reaching out. If those would be the gaskets that go behind the cooler to the water manifold or collector than yes. I would recommend replacing them. They are forgiving but if you have many Miles than it’s best to change them out.

Great question,, yes. When the cooler leaks it usually leaks internally and goes through the intake and gets burned up in the cylinder. Anything that doesn’t get burnt up will go through the exhaust and to the dpf. Hope that helps.

@@bustedknucklebydieseldr3228 good morning there jd … so when I asked the question about the egr cooler coolant leak, I’m looking at my bill and it is saying cel with multiples after treatment fault codes? What does this mean?

@@goofycomic37 this just means that you came in for a check engine light and they repaired multiple fault codes that may or may not of been related to the same issue.

Your in luck I have a video on that to.

It’s best to to do a regen to smoke out all the crap in the dpfs that caused them to be contaminated.

Thanks for reaching out. Havent seemed to work out the kinks yet. Can’t blame them though. they make these things quick on a production line. What ever happens happens right. That’s why we have job security.

@@bustedknucklebydieseldr3228 hey I don't mind you guys having some jobs security I remember when this s*** first came out you guys dealership technicians hated it so did the dealers but most guys changed their tune now when they see their timesheet at the end of the week..... I wouldn't mind you know if it only cost maybe 1,000 or two here and there but when you start getting 5 to $10,000 bills every couple weeks to couple of months plus the down time it gets kind of aggravating

@@Jackknife-TV completely understand you there nothing is cheap on these trucks and dealership labor rates are crazy expensive. But technician skills are not going away anytime soon even with all those new electric trucks coming out.

@@bustedknucklebydieseldr3228 what would cause a smell of exhaust inside the cab of truck

@@dexterzacharie8668 thanks for watching. Any exhaust leak on the truck could cause the smell to get inside the cab. Especially at an idle where the vapors just go up. With this repair coolant was getting pushed into the intake. So the only thing you might notice is low coolant level, sweet smell in the exhaust , or smoke out the exh pipe. I would just start looking for soot signs on all the clamps.

All good man and thanks for reaching out. Sometimes they does occur and usually relates to a fuel issue. A lot of times I’ll find the fuel doser after the turbo plugged up and not delivering fuel to get temps up or the fuel shut off valve in the hydrocarbon doser block isn’t switching on. Both these should throw codes and lead you to part. When they don’t throw codes il run a low temp regen and watch the numbers. Usually will have a onebox sensor far off from the rest and there’s your problem. Hopefully one of these will be your answer.

@@bustedknucklebydieseldr3228 thanks for the reply I’m only getting one code SPN 3719 FMI31 and it says Dpf zone 2 I believe i clean the dozer by the turbo witch I switch 50k miles ago and clean the dozer by the one box witch. I change 20k miles ago someone told me ny turbo could be bad.

@@bustedknucklebydieseldr3228 and do you have any videos shown the low temp regen or just run the regen and look at those numbers also will a nox sensor been out cause this also?

@@cristoperodriguezgil8075 so I don’t believe I have any videos on it. Showing numbers and understanding them is very difficult to teach. If that’s the only code than it’s a bit strange it wouldn’t throw one for low temp or regen failed to get to temp. But either way looking at a log file of a regen would be best to figure out what’s going on. Those few options are most likely cause of failure but just as easy sensors go out all the time. Hope that helps some

What it takes and what it pays is very different. It pays around 4 hrs but if you hustle you can get it done in 1 hr.

@Busted knuckle by diesel dr I pulled the hot pipe and had trace amounts of coolant it looks like. Replaced the delta sensor and it fixed my problem of low power for now. Gonna delete it soon before it bankrupts me lol.

Great question my man. This usually occurres when the EGR combustion gas is going into the coolant by means of the EGR cooler. Usually not a head issue but I would Deff take off the hot pipe going to the cold boost intake and see if it’s wet in there. If it is you found your problem.

Got same thing in 2020 and EGR cooler has crack, replaced and solved problem.

Great question. Cust stated he was using coolant and no leaks were present. When that’s the case we always press test cooling system and see if any external leaks are present. After that we take a peek inside

Great question and thanks for watching. You should never have oil in that pipe. When failures occur it’s usually injectors with fuel in that pipe which could look like oil mixed with soot. Or coolant mixed with soot which could also look like very runny oil. If it’s infact oil then I’d be concerned with some type of head failure. Hope that helps. And don’t forget these vids can make great last minute gifts for the holidays.

@@bustedknucklebydieseldr3228 thank you for your help!!!! Happy holidays!!!

Seems like something like air might be leaking because every time I turn off I have to re gain secondary tank air pressure back up. Primary air tank stays at 125psi. I’m heading to the mountains but scared to even keep heading there till I figure it out. I have port haul to smock pa. 42000lbs on time schedule am I looking at major fix?

@@ricosantana100 thanks for reaching out man. Sounds like you Deff need to take it in for service. The air leaks will only get worse and you will have a hard time maintaining you pressure after a while As for the smoking you may of got someone else’s problem and they better offer you some good will repairs to help you out. If there’s any type of coolant leaks on the Eng than they’ll be smoke from up front. If it’s smoking from your tail pipe than either coolant from your EGR cooler is getting past, burning oil pst your piston rings, or dpfs are contaminated and need inspecting. But it’s hard to say without digging in. Congrats on the new truck and license and I hope things turn around for the better.

Watch this video. It shows different tests for coolant leaks and bubbling coolant fluid. I hope this helps you. kzfaq.info/get/bejne/pbRjg9aBsb-7oH0.html

Good question, a leaking EGR cooler will saturate the dpf filters and possibly contaminate them to the point of failure. For the most part they can be burnt out in a regen but in the even a regen fails than they would need to be replaced. As for the doc’s there shouldnt be an issue with smoking them out in a regen. But in rare cases yes it might cause docs to push out and not filter properly. Hope that helps.

@@bustedknucklebydieseldr3228 thanks for replying

Smart choice on both calls. They would of both of left you cash broke and stuck.

Great question abs I wish I had an answer to that. I don’t have my own shop yet so I can’t give that out but hopefully one of these days. As always I recommend any local dealer because they have the knowledge and specialty tools needed.

If your missing this much oil and your sure it’s not on the out side of engine. I would suspect it’s going out your exhaust. So failed head or head gasket.

How long does it take to put on it and is it possible that inexperienced person can do it instead of paying the dealership $200 an hour to do it and I have gotten quotes for $1200

@@Antoniotrotter1 you just saw how to be able to tackle it yourself. Parts are the expensive part. The rest is not hard at all.

If your asking of the EGR cooler is a warranty job, it can be. Usuall extended warranty is 500 k miles for these engines.

Thanks for watching and reaching out but as for part numbers for this specifically your best bet is taking your Vin and giving it to your local dealer and getting the part numbers from them because they’re always superseding and they’re different per ghg level truck you have.
