Engine Cooling

The cooling system components are the:

• block heater
• fan blade
• fan clutch
• fan shroud
• radiator
• degas bottle
• pressure relief cap
• radiator draincock
• coolant pump
• coolant thermostat
• oil filter adapter
• upper radiator hose
• lower radiator hose
• degas bottle supply hose
• vent hose(s)
• fan stator - 6.0L
• engine appearance cover - 6.0L

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 distilled water.

To maintain the integrity of the coolant and the cooling system:

CAUTION: With the engine cold, fill vehicles without a yellow fill level decal on the degas bottle only to the MIN line. The correct fill level on these vehicles is between the MIN line and 15 mm (0.59 in) below the MIN line. Fill vehicles with a yellow fill level decal to within the yellow cold fill range shown on the decal. These fill levels will allow for coolant expansion. Overfilling the degas bottle may result in damage to the pressure cap, which can cause the engine to overheat.
• Add Motorcraft Premium Gold Engine Coolant VC-7-A (in California and Oregon VC-7-B, in Canada VC-7-C) or equivalent meeting Ford specification WSS-M97B51-A1 (yellow in color). Do not mix coolant types.
• Do not add/mix orange-colored Motorcraft Specialty Orange Engine Coolant VC-2, meeting Ford specification WSS-M97B44-D. Mixing coolants may degrade the coolant's corrosion protection.
• Do not add alcohol, methanol, 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. Use of such coolants may harm the engine and cooling system components. Do not mix coolant types.
