• Do not add/mix extended life coolants such as Motorcraft
Specialty Orange Engine Coolant, VC-3 (U.S.) or CXC-209
(Canada), meeting Ford specification WSS-M97B44–D, with the
factory-fill coolant, Motorcraft Premium Gold Coolant meeting
Ford Specification WSS-M97B51–A. Mixing Motorcraft Specialty
Orange Engine Coolant or any equivalent extended life engine coolant
with this factory-fill coolant can result in degraded corrosion
protection.
• A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
• Do not use alcohol, methanol or brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant). Alcohol
and other liquids can cause engine damage from overheating or
freezing.
• Do not add extra inhibitors or additives to the coolant. These
can be harmful and compromise the corrosion protection of the engine
coolant.
• Do not mix with recycled coolant unless from a Ford-approved
recycling process (see Use of Recycled Engine Coolant section).
To reduce the risk of personal injury, make sure the engine is
cool before unscrewing the coolant pressure relief cap. The
cooling system is under pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (an opaque plastic bottle).
Slowly turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above). If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full.
