Mercedes OM642 Oil Cooler Seal Replacement
E350 CDIOil Cooler Seal Replacement9 Oct 2026
A common shortfall of the OM642 is the oil cooler - Two seals that stop oil and coolant from leaking the engine are common to fail on these engines, worse yet they're hidden at the bottom of the V style engine requiring complete stripping to access.
