Abstract:

The thermostat mounting assembly is used to support a thermostat at a location between an engine block and a radiator. The housing has a fluid inlet port and a fluid outlet port with a support assembly used to rigidly fix the thermostat in place within the housing. A manually operable mechanism is connected to the housing to effect a continuous flow of coolant liquid to by-pass the position of the thermostat between the engine block and the radiator.
