Jeep Liberty: Cooling System Pressure Cap

Jeep Liberty / Jeep Liberty Owner's Manual / Maintaining Your Vehicle / Maintenance Procedures / Cooling System / Cooling System Pressure Cap

The cap must be fully tightened to prevent loss of coolant, and to ensure that coolant will return to the radiator from the coolant recovery bottle.

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 engine 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 engine damage may result.
