Cooling System: Description and Operation
Engine CoolingThe engine cooling system consists of the:
^ block heater
^ fan blade and clutch
^ fan shroud
^ radiator and cap
^ radiator coolant recovery reservoir
^ water thermostat
^ water pump
^ water temperature indicator sender unit
Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle.
When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable water.
To maintain the integrity of the coolant and the cooling system:
^ Add Motorcraft Premium Engine Coolant VC-4-A (CXC-10 in Canada, VC-5 in Oregon) or equivalent meeting Ford specification ESE-M97B44-A.
^ Do not add orange-colored extended life coolant VC-2 or equivalent meeting Ford specification WSS-M97B44-D. Mixing coolant may degrade the coolant's corrosion protection.
^ Do not add alcohol or methanol or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing.
^ Do not mix with recycled coolant unless it meets the requirements of specification ESE-M97B44-A. Not all coolant recycling processes meet this specification; use of such a coolant may harm the engine and cooling system components.
