Engine Coolant Refill Procedure - Ford SVT Mustang Cobra Owner's Manual

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 avoid 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.

Engine coolant refill procedure

The following procedure should be used when
refilling the cooling system after it has been drained
or become extremely low.
1. Remove the pressure relief cap from the engine
coolant reservoir as previously outlined.
2. Slowly add a 50/50 mixture of engine coolant
and distilled water to the engine coolant reservoir
until the coolant level is at the "cold fill level" as
listed on the reservoir.
