Jeep Grand Cherokee Oil in Coolant.

This fault applies to the WK2 Jeep Grand Cherokee with a 3.0 Diesel engine. Often People mistake the oil in the cooling system fault for a blown or faulty head gasket or cylinder head issue. Before going there, first you need to check and replace the engine oil cooler. Its a super common fault with these engines.

There is also an issue with the cooling hoses becoming problematic after the oil has entered the cooling system. Once this has occurred. we advise replacing the hose in the valley, the z hose and the turbo charger coolant hose.
