Case Number: S2009000004
Date: 11/16/2020
Symptom/Vehicle Issue: Oil Leak Between The Engine Oil Cooler/Filter Housing, And
The Engine Block.
Discussion: A small number of customers may experience an oil leak. Upon further
inspection, the leak may be traced to the area between the engine oil cooler/filter
housing assembly, and the engine block. Analysis of the returned oil cooler/filter
assemblies have all been deemed as Trouble Not Found (TNF). Further investigation
into oil leaks in this area have indicated two possible scenarios.
Scenario #1, Residual Oil from Engine Manufacturing:
When the engines are manufactured, the first oil fill is done through an access hole in
the oil filter housing assembly. During this first fill, it is possible for residual oil to be
spilled, and collect in the gap between the oil cooler and the oil cooler bracket. See
(Figure 1).

NOTE: Do NOT use any hydrocarbon based cleaners like carburetor or brake
parts cleaners to clean the residual oil. Damage to the surrounding gaskets can
result
Before replacing any parts, thoroughly clean the area using an isopropyl alcohol or
citrus based cleaner. Dry the area using compressed shop air for a minimum of 20
seconds. See (Figure 2).
Once complete, run the engine to see if leak is still present. If the leak is still present,
and if the location is verified to be between the oil cooler assembly and the block, refer
to Scenario #2.

Scenario #2, Active Oil Leak from the Oil Cooler/Filter Housing Gasket:
If Scenario #1 has been followed, and the leak is still present, then the issue may be
with the gasket between the oil cooler/filter housing and the engine block. Do NOT
replace the entire oil cooler/filter housing for a leak from the gasket. The gasket is
currently available separately through Mopar. Please refer to the current StarParts
catalog for the proper part numbers.
