MAINTAINING YOUR VEHICLE 539 Cooling System Coolant Checks WARNING! • When working near the radiator cooling fan, disconnect the fan motor lead or cycle the ignition switch to the LOCK position. The fan is temperature controlled and can start at any time the ignition switch is in the ON position. • 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 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-12106) only according to Chrysler Service Manual procedure or by an authorized dealer. Check the front of the radiator 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 tubing for brittle rubber, cracking, tears, cuts, and tightness of the connection at the bottle and radiator. Inspect the entire system for leaks. 7
