2024-2025 Jeep Coolant Leak From Thermostatic Valve Gasket TSB

Introduction

Jeep has issued Technical Service Bulletin (TSB) 07-002-25 REV. A and Rapid Service Update (RSU) 25-063 to address a common issue of engine coolant leaks. This bulletin, dated May 2, 2025, supersedes a previous version of TSB 07-002-25 from April 15, 2025. It specifically targets certain 2024-2025 Jeep Renegade and Compass models equipped with 1.3L I4 Turbo MAir DI engines.

Symptoms

Owners of affected vehicles may notice a Jeep Compass coolant leak or a similar leak in other models. The primary symptom reported is "Coolant is leaking at the thermostatic valve." This indicates a potential failure of the thermostatic valve gasket, leading to visible coolant loss.

Diagnosis

To diagnose a Jeep Compass coolant leak or a leak in other affected models, technicians will first verify the vehicle's VIN against the Rapid Service Update (RSU) VIN list. If a coolant leak from the thermostatic valve is confirmed, the repair procedure is initiated. For vehicles not on the specific VIN list but exhibiting the symptom, a diagnostic procedure is followed:

• If equipped, remove the under engine protection cover. Detailed service procedures are available in DealerCONNECT/Service Library under "Service Info> 7055B54 - Under Engine Protection - Removal/Replacement."
• Start the vehicle and allow the coolant temperature to reach 90 °C (194 °F).
• Inspect the thermostatic valve and its surrounding area for evidence of leaking coolant. Figures in the TSB illustrate the inspection area and examples of a coolant leak.

Repair Procedure Summary

The repair for the Jeep Compass coolant leak involves inspecting and, if necessary, replacing the thermostatic valve gasket. If a leak is confirmed during diagnosis, the technician will proceed with the following steps:

• Remove the existing thermostatic valve.
• Replace the thermostatic valve gasket.
• Refer to detailed service procedures in DealerCONNECT/Service Library under "Service Info> 1088C40 - Thermostatic Valve - Removal/Replacement - Including necessary procedures" for precise instructions.
• If no leak is found after inspection, an Inspection Labor Operation (07-40-10-91) is used to close the active RSU, and the under engine protection cover is reinstalled.
