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.
If you must remove the pressure relief cap or
radiator cap (depending upon engine application),
follow these steps to avoid personal injury:
1. Before you remove the cap, turn the engine off
and let it cool.
2. When the engine is cool, wrap a thick cloth
around the cap. 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.
