RE: CM870 ISX EGR Cooler and Oil Cooler
If the oil cooler was leaking, then you would have oil in your coolant.

If you suspect the EGR cooler leaking then pull off the egr pipe where it meets the intake and crank it up. See if steam and coolant come out of it.


I would suggest pressurizing your coolant system to 20-PSI with a coolant pressure test kit and find where the coolant is going.

Have you done any oil sampling and sent it to a lab so that it can be checked for coolant getting in the oil?
