432 MAINTAINING YOUR VEHICLE
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
recovery tank.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
• The warning words "DO NOT OPEN HOT" on the
cooling system pressure cap are a safety precaution.
Never add engine coolant (antifreeze) when the en-
gine is overheated. Do not loosen or remove the cap
to cool an overheated engine. Heat causes pressure to
build up in the cooling system. To prevent scalding or
injury, do not remove the pressure cap while the
system is hot or under pressure.
• Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
