Oil Cooler Gasket Set – Mercedes W163 / W202 / W203 | OEM 1121840361 1121880401

The oil cooler gaskets on the Mercedes W163, W202, and W203 seal the oil cooler to the engine block. When they fail, oil or coolant leaks at the cooler mounting face — potentially leading to oil/coolant mixing. This complete gasket set restores a leak-free oil cooler seal.

Fits OEM #1121840361.
