Basically there are two possible issues with this part. The first is the cooler internally fails which fills the cooling system with engine oil. This can cause the engine to overheat, damage the cooling system components and then leak coolant and water.
The second fault is far more common. This fault is the failure of the oil cooler gasket between the manifold and cooler itself. When this gasket fails the engine empties itself of oil and coolant very quickly. This fills up the valley and then leaks out the end all over the top of the transmission.
To access this requires the removal of the inlet manifold. It is advised to replace the manifold gaskets at the same time.
It is also advised that the entire cooler be replaced regardless of the the issues. Replacing just the gasket is an option however with the cooler internal failure fault being so common we advise replacing it whilst there. The risk of not replacing this is you may be up for the labour all over again if the cooler fails in the near future.
The cost of this part from Jeep is not as expensive as the Grand Cherokee option. A capable technician should be able to carry out this repair in around six hours.
