The coolant expansion tank on your Mercedes-Benz is used not only as a coolant reservoir, but also a vessel for additional coolant to flow to once the engine warms up, and the coolant expands.

Being made of plastic though, this coolant expansion tank will eventually become brittle and crack due to numerous heating and cooling cycles. Once this tank cracks, it must be replaced in order to hold the pressure generated by the cooling system.

If it is time to replace the coolant expansion tank on your Mercedes-Benz, be sure you have everything you need to do the job correctly. Euromotiv carries a full line of cooling system components, as well as the correct coolant for your car.
