CAUTION: Do not rotate the coolant pump housing once installed in the engine.
Damage to the O- ring seal can occur, causing the coolant pump to leak.
NOTE: Install a new O- ring seal and lubricate with the same clean engine coolant that is
present in the system. Do not mix coolant types.
To install, reverse the removal procedure. Klj . 3 ba

DESCRIPTION AND OPERATION
Supercharger 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 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.
NOTE: The air that is produced from the supercharger is cooled by the intercooler.
Walter C. Avrea, the owner of patents 3,601,181 and RE 27,965, has granted Ford Motor Company
rights with respect to cooling systems covered by these patents.
The cooling system components include the:
zintercooler
z intercooler radiator (8K226)
z pressure relief cap
z degas bottle
z electric water pump (8501)
The degas bottle:
zprovides a location for system fill.
z contains coolant expansion and system pressurization.
z provides air separation during operation.
z replenishes the intercooler coolant to the system.
The intercooler coolant flows:
zfrom the intercooler to the degas bottle.
z from the degas bottle to the water pump.
z from the water pump to the intercooler radiator.
z from the intercooler radiator to the intercooler.
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: SECTION 303-
