CRUSADER LOWER THERMOSTAT CARTER
Lower thermostat housing for Crusader engine.

The thermostat housing holds the thermostat in place and ensures a sealed coolant flow between the engine and the cooling system. It's a crucial link in engine temperature control.
Made from aluminum, brass, or reinforced plastic, the housing resists saltwater corrosion and temperature extremes, making it ideal for demanding marine environments.
We supply housings compatible with Volvo Penta, Mercruiser, OMC, PCM and other major marine engine brands. Easy to install and essential for engine protection.
