Radiator Fan Control

The radiator has a single cooling fan, with a two speed motor. The fan is controlled by the Powertrain Control Module (PCM) which energizes the fan relay. Fan operation is accomplished three ways:
^ When air conditioning system pressure reaches 210 psi, fan will operate.
^ Coolant temperature reaches 215° F. fan will operate.
^ Models equipped with automatic transmission, a fluid thermistor may have some influences on fan operation.
^ Refer to image for fan operation.
