How do you remove termostat housing?

To remove the thermostat housing, first ensure the engine is cool and disconnect the battery. Drain the coolant from the radiator and remove any components obstructing access to the housing, such as hoses or brackets. Unscrew the bolts securing the thermostat housing and carefully lift it off, taking care not to damage the gasket surface. Clean the mating surfaces thoroughly before installing the new thermostat housing.
