Symptoms

If your 2021-2024 Jeep Compass or Renegade is affected by this issue, you may observe the following:

• Oil leaks from the engine compartment.
• Oil leaks from the engine/transmission coupling.

Diagnosis and Trigger Conditions

When a customer reports a potential oil leak, technicians must first confirm the claimed fault. The diagnostic process involves establishing the precise origin of the oil leak. It is crucial to ensure the leak is not coming from the engine head, oil pan, or crankshaft oil seal. This Technical Service Bulletin (TSB) 09-021-24 should only be applied if leaks from other external engine components can be definitively excluded.

Before any disassembly, a dye relevant liquid should be added to the engine oil, and the engine should be run for 30 minutes. This helps to accurately identify the source of the leak after the flywheel has been removed. Technicians are advised to document the intervention with photographs to accurately identify the source of the leak.

Repair Procedure Summary

The repair for the Jeep Compass Renegade oil leak involves replacing the engine valley cap. The general procedure outlined in TSB 09-021-24 is as follows:

1. Add a dye to the engine oil and run the engine for 30 minutes to help pinpoint the leak source after the flywheel is removed.
