Condition

Some customers may comment about an engine oil leak.

Cause

Engineering suspects an oil leak may be developing in the area of the A/C compressor bracket and would like to get further information. If a vehicle comes in to your dealership with an engine oil leak, complete the following steps:

Clean the side of the engine where the oil appears to be leaking from.
Install engine oil dye and run the engine or test drive the vehicle until you are able to identify the source of the oil leak.
If the oil leak is detected in the area of the A/C compressor bracket, contact engineer Brad Clark at 248-857-2708. If Brad is unavailable, contact Larry Szlachta at 248-255-7649. For oil leaks detected in other areas, repair based on information in SI.
