I have a 2015 ecodiesel and the coolant is turning black. I will do a combustion leak test this week to see if it is a head gasket. I looked on here and am seeing a bad oil cooler could be the problem. Is the oil cooler different than the EGR cooler? Where is the oil cooler located? Never started turning black until after they replaced the EGR cooler under the recall.

Thanks,

Greg

The oil cooler is also part of the oil filter assembly.

@Crash68 kool and thanks for the quick response. Was hoping to save some money but oh well. Guess I will have to take a weekend to fix the oil cooler and the intake manifold. Anything else that could be done for preventative maintenance?

Its a new post today. You both have a recent EGR replacement in common.
Look at that timing. Both of them having oil in the coolant after egr replacement.. 🤷🏻‍♂️ That sounds pretty suspect. I’d be questioning the repair job that could have led to this.

Before I tried fixing it myself I would absolutely be going back to the dealer who did my EGR.

How long since they did the EGR?

It has been around a year. They put new coolant in but now its starting to change. Ill keep an eye on it and probably change the oil cooler out when I do the manifold. Wish they replaced the manifold when they did the EGR but I didn't know much about the ecodiesel at the time I bought it.
