DESCRIPTION AND OPERATION
Engine Cooling
CAUTION: Vehicle cooling systems are filled with Motorcraft Premium Gold Engine
Coolant VC -7-A (in Oregon VC -7-B) 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 mix coolant types.
NOTE: The addition of Motorcraft Cooling System Stop Leak Pellets, VC- 6, darkens Motorcraft
Premium Gold Engine Coolant from yellow to golden tan.
The 4.6L cooling system components include the:
zblock heater
z engine coolant temperature (ECT) sensor
z fan blade, fan motor and fan shroud assembly
z radiator
z pressure relief cap
z radiator draincock
z coolant pump
z coolant thermostat
z oil filter adapter
z radiator overflow hose
z upper radiator hose
z lower radiator hose
The radiator overflow hose circulates the coolant.
The coolant thermostat:
zcontrols the engine coolant temperature.
z allows for quicker engine warm- up.
The degas bottle/coolant expansion tank:
zprovides a location for service fill.
z contains coolant expansion and system pressurization.
z provides air separation during operation.
z replenishes the engine coolant to the system.
The engine coolant flows:
zfrom the lower radiator hose to the coolant pump.
z from the coolant pump to the engine block and the cylinder heads.
