V45 SWITCHES THERMOSTATIC SWITCH The cooling fan motor is actuated by the thermostatic switch located in the left tank of the radiator. Run the engine until coolant temperature reaches 88-92°C (191-197°F). The fan motor should start running. The fan motor should stop when the coolant temperature drops to 83-87°C (182-188°F). THERMOSTATIC SWITCH If the fan motor does not start, disconnect the black and green leads from the thermostatic switch and short them together with a jumper wire as shown. Turn the ignition switch on. The cooling fan motor should start running. If it starts, replace the fan thermostatic switch and retest. If it does not start, check for battery voltage from the black lead (positive) to black/blue (negative) of the fan motor coupler. If there is no voltage, check for a blown or faulty fuse, loose terminals or connectors, and an open circuit.
