Engine Cooling 303-03C-3 303-03C-3 DESCRIPTION AND OPERATION Engine Cooling 1 2 E129078 Item Description 1 Radiator 2 Cooling fan motor and shroud 3 Coolant expansion tank 4 Coolant pump 5 Thermostat 6 Coolant pump pulley 3 4 5 6 CAUTION: If the coolant concentration is insufficient, low temperature protection and corrosion resistance will be impaired. NOTE: Providing the coolant has not been contaminated with other fluids or foreign material, the robust corrosion resistance properties of this coolant means that it can be reused after changing an aluminum cooling system component. The concentration should always be checked and maintained within the specification.

Engine Cooling 303-03C-4 303-03C-4 DESCRIPTION AND OPERATION Coolant concentration should be checked through the neck of the coolant expansion tank with a hydrometer. The acceptable range of specific gravity (sg) must be maintained. The coolant used is an orange colored Motorcraft Super Plus 2000 engine coolant. This is a non silicated organic acid technology (OAT) coolant that must not be mixed with other coolant types. For cooling system top up, only use coolant which meets the correct specification.
