| Description and Operation 2.0L Duratec RS 3 - Cooling fan motor and shroud Engine Coolant WARNING:Disconnect the battery when working in the vicinity of the engine cooling fan. The fan is controlled by the engine management system and an increase in coolant temperature may cause the fan to operate even with the ignition in the OFF position. Failure to follow this instruction may result in personal injury. WARNING:Engine coolant contains monoethylene glycol and other constituents which are toxic if taken internally and can be absorbed into the skin after prolonged contact. Engine coolant concentration should be checked through the neck of the expansion tank with a hydrometer. The acceptable range of specific gravity (sg) of correctly balanced fluids is between 1.06 and 1.07kg/l, which represents an engine coolant concentration between 40% and 55%. If the concentration falls below 40% there is insufficient low temperature protection and the corrosion resistance will be inadequate. In such cases the concentration must be brought back to specification. The coolant used is Motorcraft Super Plus 2000. This is a non silicated organic acid technology (OAT) coolant, and must not be mixed with other coolant types. For cooling system top up, only use coolant which meets the correct specification and is compatible with the existing coolant.

Changing Coolant WARNING:When releasing the system pressure, cover the expansion tank cap with a thick cloth to prevent the possibility of coolant scalding. Failure to follow this instruction may result in personal injury. CAUTION:When draining the coolant or changing any cooling system components, it is imperative that no coolant comes into contact with the camshaft drive belt or accessory drive belt. If necessary the belt should be removed. Contamination of the belt may result in belt failure. CAUTION:Providing the coolant has not been contaminated with other fluids or foreign matter, the robust corrosion resistance properties of this coolant means that it can be re-used after changing an aluminium cooling system component, although the concentration should always be checked and maintained within specification. This engine coolant should be changed after a period of 10 years or 150 000 miles, whichever occurs sooner. Refill the cooling system with coolant which meets the correct specification and is compatible with the existing coolant.
