If You Must Remove The Pressure Relief Cap Or Radiator Cap - Ford Mustang 2001 Owner's Manual

• 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).
If equipped with the 3.8L V6 engine, to
avoid scalding hot steam or coolant from
being released from the engine cooling system,
never remove the radiator cap from the radiator
while the engine is running or hot. Failure to
follow this warning may result in damage to the
engine's cooling system and possible severe
personal injury.
If equipped with the 4.6L V8 engine, to
avoid scalding hot steam or coolant from
being released from the engine cooling system,
never remove the pressure relief cap from the
engine coolant reservoir while the engine is
running or hot. Failure to follow this warning may
result in damage to the engine's cooling system
and possible severe personal injury.
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.
