The factory composite plastic thermostat housing is one of the weakest links in the BMW cooling system! The plastic thermostat housing becomes very brittle over time and can break causing your car to overheat. The robust Aluminum thermostat housing is much stronger and your best chance in preventing more costly repairs by addressing this common failure before it happens to you!
