2025-2026 Jeep Compass/Renegade Coolant Leak TSB

This Technical Service Bulletin (TSB) 07-004-25, also identified as Rapid Service Update (RSU) 25-233, addresses a specific coolant leak issue affecting certain 2025-2026 Jeep Compass and Renegade vehicles. This bulletin is primarily applicable to South America markets, despite some market codes indicating broader applicability. The issue stems from a manufacturing defect in the water pump cover.

This 2025 Jeep Compass manufacturer_communication provides detailed instructions for inspecting and, if necessary, replacing the water pump cover to resolve the coolant leak.

Symptoms

Owners of affected vehicles may experience the following:

• "Coolant is leaking."

Cause

The root cause of the coolant leak is identified as a "Water pump cover injection process failure." This indicates a manufacturing defect in the water pump cover itself.

Important Warnings

Owners and technicians should be aware of critical safety and procedural notes:

• Coolant Reservoir Cap: "Do not open the reservoir cap when the engine is hot. Wait until the engine cooling system has cooled to avoid risk of burns."
• Battery Disconnection: If your vehicle is equipped with an Intelligent Battery Sensor (IBS), the negative terminal of the battery should not be disconnected. In this case, the "FALSE" pole must be disconnected from the battery.
• Post-Repair Reporting: After applying this TSB 07-004-25, "it is not necessary to send DID-I or DID-A."

Diagnosis

To determine if this TSB applies, technicians will first check the vehicle's VIN against the Rapid Service Update (RSU) VIN list or perform a VIN search in DealerCONNECT/Service Library. If the vehicle is on the list, the repair procedure should be followed. If the vehicle is not on the VIN list but exhibits the symptom of "Coolant is leaking," the repair procedure should still be performed.

Diagnosis involves visually inspecting the water pump cover area for evidence of coolant leakage using a flashlight, after bringing the engine to operating temperature.

Repair Procedure Summary

The repair procedure outlined in TSB 07-004-25 involves several steps to address the water pump cover issue:

1. Preparation: Open the hood, start the engine, and accelerate to 3000 rpm until the engine reaches its operating temperature (90°C/194°F) with coolant activated. Remove the clean air tube.
2. Inspection: Using a flashlight, check for coolant leakage around the water pump cover. If a leak is found, proceed with replacement. If no leak is found, the inspection labor operation (07-50-02-90) is used to close the RSU.
3. Disassembly: Disconnect the negative battery terminal (or the "FALSE" pole if equipped with IBS). Remove the engine cooling supply expansion reservoir cap (only when cold). Remove the right front wheel and the supplementary protection of the front right wheel arch. Then, remove the screws securing the water pump cover and remove the cover itself.
4. Replacement: Install a new gasket on the new water pump cover.
5. Reassembly: Assemble the new water pump cover to the engine, tightening the screws to 9 N·m (80 in. lbs.) in the specified numerical sequence. Reinstall the supplementary protection and the right front wheel.
6. Coolant Refill and Bleeding: If a Mopar® Essential Tools and Service Equipment Tool, U-View Airlift™ Cooling System Refill (399-550000) or equivalent is available, use it to fill and bleed the cooling system. Otherwise, open the air box hose bleed valve, auxiliary pump bleed valve, radiator bleed valve, and supplementary radiator bleed valve. Fill the coolant until bubbles stop coming out of the bleed valves, then close them and the expansion tank cap.
7. Final Checks: Connect the battery terminal. Run the vehicle to check for leaks. Turn off the vehicle, wait 5 minutes, and check/top up the coolant level. Reinstall the clean air tube.
8. Steering System Recalibration: After battery reconnection, the electric steering system must be recalibrated. This involves turning the steering wheel full stop left, then full stop right, and returning it to the center position. A road test at speeds above 12 mph (20 km/h) may be necessary until any steering warning indicators turn off.
