Cooling System: Description and Operation

Engine Cooling

CAUTION: Some vehicle cooling systems are filled with Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specification ESE-M97B44-A (green color). Others are filled with Motorcraft Premium Gold Engine Coolant VC-7-A or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Always fill the cooling system with the same coolant that is present in the system. Do not Nix coolant types.

The cooling system components are the:
^ block heater
^ engine coolant temperature (ECT) sensor
^ fan blade, fan motor and fan shroud assembly
^ radiator
^ pressure relief cap
^ radiator draincock
^ water pump
^ water temperature indicator sender unit
^ water thermostat
^ oil filter adapter
^ radiator overflow hose

The radiator allows excess engine heat to be transferred to the air.

Radiator tanks cannot be repaired.

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 Ford Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specification ESE-M97B44-A (green color), or Motorcraft Premium Gold Engine Coolant VC-7-A or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Do not mix coolant types.
^ Do not add orange-colored Motorcraft Specialty Orange Engine Coolant VC-2 or equivalent, meeting Ford specification WSS-M97B44-D. Mixing coolants may degrade the coolant's corrosion protection.
^ Do not add alcohol, methanol or brine 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 Ford specification ESE-M97B44-A or WSS-M97B51-A1. Not all coolant recycling processes meet these Ford specifications. Use of such a coolants may harm the engine and cooling system components. Do not mix coolant types.
