Thermostat: Specifications

TYPE 

The engine cooling thermostats are a wax pellet driven, reverse poppet choke type. 

OPERATING RANGES 

Warm up 
They are designed to provide the fastest warm up possible by preventing leakage through them and to guarantee a minimum engine operating
temperature of 88 - 93°C (192 - 199°F). 

Fully Warm Engine 
They also automatically reach wide open so they do not restrict flow to the radiator as temperature of the coolant rises in hot weather to around
104°C (220°F). Above this temperature the coolant temperature is controlled by the fan, the radiator, and the ambient temperature, not the
thermostat.
