Oil cooler replaced, coolant leaking
Please help... 2012 ML350 Bluetec OM642
Replace orange seals with Viton Purple seals, installed turbocharge and everything in place. Car starts perfect...
but leaking coolant from down below. Not sure where from. Please let me know how to check where the coolant is leaking and what are my next steps.
Oil cooler was perfectly cleaned and installed with torque wrench.
Any help appreciated. Thanks.
