SYSTEM CHECK-OUT
After completing the installation, the fan can be tested for function by
starting the engine with no air in the system. The fan should operate
immediately after the engine is started and should stop as the air
pressure builds up over 80 psi. As soon as the air system reaches
governor cut-out pressure, before the engine reaches operating
temperature, shut off the engine and check for air leaks. If it is
desired to check the fan at operating temperature, it may be
necessary to cover the radiator temporarily and run the engine at fast
idle until operating temperature is attained.
Thermo-Pneumatic Control Valves
Used in all fan clutch installations and
controls the fan clutch. Closing temperature
should be 10° higher than the engine
thermostat (fully open position).
