Cascadia, DD15 coolant contaminated with oil and how to fix it.

Common problem with the DD15 and DD13 is oil will start to contaminate the cooling system. The first place you will notice this will be inside the coolant surge tank (expansion tank). The tank will start to get dark and stain with oil.
This will most likely be the seals at the oil cooler. This will require the complete oil/coolant module to be removed in order to gain access.
The job will take about 6-10 hours, after which the coolant system will need to be flushed (cleaned).
Oil that is removed, must be replaced with new motor oil. New oil filter and coolant filter must be used.
Oil seals will need to be replaced, oil cooler can be used but you must pressure test before reinstalling. Oil cooler must be torqued to 22 ft lb, new mounting gasket must installed and torqued.
If you have any questions, please consult a professional or your manual.

Hi, Pedro. Another great video. Ive done this on mine. Btw there's a drain plug for the coolant in the module. I'd still changed the oil just in case. Ive just done injector cup seals because my truck mixed fuel in coolant and it stinks. Im interested in what kind of product you use for the flush and what procedure you prefer.

So i was running little bit hot than engine was used to and also running really hot when hauling 38-44k lbs. noticed less than inch of oil over coolant in coolant tank. Oil dipstick "seems" fine with just oil in it. So my question is what are chances that my head gaskets is out? Or is it this issue you showed us? I do leak coolant somewhere that i can not figure out. Also i can see that drivers side of engine is wet.

[@stilliraise9201]

So why seals get cracked. That is why people are saying DPF is overheating the engine

[@le3ch90]

Would the EGR cooler be a possible culprit for the oil in coolant? Maybe even the transmission cooler that’s on the radiator?

[@CarlosDieselElectric]

Coolant goes through the cooler to cool off the exhaust gases. So oil in the coolant would be coming from a different source. Not likely from the radiator, although might be possible. The seals on the oil cooler are usually the source of the problem. How many miles are on the truck?

[@le3ch90]

@@CarlosDieselElectric ahh that’s right. I was thinking it was like a Cummins. They got a big problem with the seals for the egr cooler. I think the truck has like 300k maybe. I replaced the seals 1 time already and the oil cooler. Gotta get some time to check it out again

[@CarlosDieselElectric]

@@le3ch90 The seals over time get hard and that is where the leaks start. I would start there, least expensive place to start. Mostly labor, try doing it when the truck is due for service.

Is there any recommendation when we should replace it or is it one of those things when it breaks you fix it.

[@keepitreal8804]

My detroit 60 series has oil in coolant resevoir and coolant level has been going down very rapidly as well. Is this head gasket issue? Or a transmission cooler or an oil cooler issue?

[@CarlosDieselElectric]

I would lean towards the oil cooler. Most likely culprit

[@steveerpelding6415]

Is this the only place oil will get into the water system? Or was there a diagnostic test you didn't show ?

[@CarlosDieselElectric]

This is the only place I have found where coolant can be introduced into the cooling system unless possibly the cylinder head but unlikely. The oil cooler, seals or the module itself. I have only seen the cylinder head be the issue one time and that was because mechanic that overhauled it prior to it coming to my shop installed an EPA 10 block with a GHG 14 cylinder head. They are not compatible.

[@CashNYC]

you what's crazy I replace the gasket on that oil module if I had known while I was there I could have replace those gasket to not have that problem in the future. My next oil change I'm gonna pull it back down and drain coolant and replace those two gaskets. I rather that than oil and coolant mixing then be force to do it.

[@abdiqaniadan2349]

How long did you have this issue before you fixed it and where is the shop

[@CarlosDieselElectric]

The issue can take time to present itself. The driver needs to looking at the coolant tank to see if there are any changes. Once the customer saw the issue, he brought it in right away. The job takes around 10 hours, plus you will need to flush the entire cooling system several times in order to get as much of the oil as possible. The flushing of the system takes 4-5 attempts

I have coolant loss a gallon a day no external leak is it possible that I have same issue or it might be leaking inside egr cooler?

[@CarlosDieselElectric]

I would look into the EGR cooler being the issue. Check the cross over hot pipe, remove and inspect it inside. It should be dry and soot should only be present. If it is wet, then most likely you have and EGR cooler. Try checking this after you run the truck.

Can I reuse the engine oil And coolant

[@CarlosDieselElectric]

I would not. Once I remove motor oil I always add new. I personally won’t run the risk of damaging the engine because of debris or something in the oil (or container) that was removed. Coolant, if you have contaminated coolant then it gets dumped and go with new.

[@kelvingonzalez2774]

Hey anyone know why the coolant goes down on the surge tank when you accelerate DD13? Than when you let go of the throttle the coolant rises back in the surge tank? It literally goes below min and than back to max when you let go of the petal... once a week we have to add half of gallon...No egr leak... Please help anything ideas helps

[@CarlosDieselElectric]

You may have an internal problem. Could also be the surge tank. Try having your mechanic pressurize the coolant system. How many miles does the truck have? What year is the truck?

How much is it cost to replace

[@CarlosDieselElectric]

Parts are not that expensive, you will need to change the oil, flush the coolant system. That is where pricing will change depending on how dirty the system is. It may require multiple times before most of the oil is out of the cooling system.

When we supposed to adjust valves. My freightliner 2019 has 300k

[@CarlosDieselElectric]

The interval Detroit recommends is at 100,000 miles, 250,000 miles and then at 500,000 miles. I don't completely agree with this interval because I have seen valves need adjustment every 100,000 miles. So there are different factors that come into play when it comes to valve adjustment intervals.

My coolant in 2012 dd 13 going straight to oil pan

[@CarlosDieselElectric]

Sounds like a liner is leaking coolant directly into the oil system. You will need to remove the oil pan, apply some pressure to the cooling system and look for the leaking liner. This is most likely the issue.

[@tonybrown8692]

@@CarlosDieselElectric recommended way of doing this without the oil pan

[@CarlosDieselElectric]

@tonybrown8692 in order to see which liner is leaking, this is the only way. Unless you have a cracked block or cylinder head issue. But coolant going directly into the oil most likely a liner seal that has let out. This will need to be fixed, not just by replacing the seal on the liner but finding the root cause.
