What should I do if I suspect a leak from the new tank?

Immediately check all hose connections and the tank cap for tightness. Inspect the tank body for any visible cracks. If a leak persists, contact customer support.

Troubleshooting

Coolant level drops rapidly after installation.

Ensure the expansion tank cap is properly tightened and sealed. Check all hose connections for leaks. The system may require further bleeding to remove air pockets.

Engine overheating persists after replacement.

Verify the thermostat is functioning correctly. Check the radiator for blockages and ensure the cooling fan is operating. Confirm the expansion tank was the correct part for the vehicle.

Small leaks observed around hose connections.

Re-seat the hoses and ensure hose clamps are tightened appropriately. Replace any damaged or worn hoses.
