Failure Symptoms

The first sign of a failing expansion tank is often a visible coolant leak, typically around the tank's seams or hose connections. If left unaddressed, the coolant level will continue to drop, leading to increased engine operating temperatures. Continued operation with a compromised cooling system risks severe engine damage due to overheating.

Installation Tip

Ensure the cooling system is completely cool before draining and removing the old tank to prevent burns. Avoid overtightening the mounting bolts, as this can crack the plastic tank.

Service Note

Inspect all coolant hoses and the radiator cap for leaks or degradation when replacing the expansion water tank.
