492 MAINTAINING YOUR VEHICLE Cooling System Coolant Checks WARNING! • When working near the radiator cooling fan, disconnect the fan motor lead or place the ignition in the LOCK position (OFF position for Keyless Enter-N-Go™). The fan is temperature controlled and can start at any time the ignition switch is in the ON position (RUN position for Keyless EnterN-Go™). • You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you see or hear steam coming from under the hood, do not open the hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the radiator is hot. Check the engine coolant (antifreeze) protection every 12 months (before the onset of freezing weather, where applicable). If the engine coolant (antifreeze) is dirty, the system should be drained, flushed, and refilled with fresh OAT coolant (conforming to MS.90032) by an authorized dealer. Check the front of the A/C condenser for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the condenser. Check the coolant recovery bottle and/or the supercharger coolant recovery bottle (if equipped with the 6.2L Supercharged engine) tubing for brittle rubber, cracking, tears, cuts, and tightness of the connection at the bottle and radiator. Inspect the entire system for leaks.
