What to check when you find oil in coolant or antifreeze:
– if the engine block is cracked
– if you have a bad oil cooler gasket or damaged oil cooler
– damaged or bad head gasket
– cracked pistons
– compromised oil cooler

We have check the coolant and the fluid looks black and milky, so definitely the coolant is contaminated with engine oil. So, will start with replacing the oil cooler beacuse we think that is the problem.

Here you can see that we have a Mercedes-Benz oil cooler that we will install on the car instead of the old one.

The oil cooler is located on the left side of the engine, hidden under other engine parts.
To get to the oil cooler, we will have to remove several parts from the engine compartment.
