MAINTAINING YOUR VEHICLE 397 WARNING! Exhaust gases can injure or kill. They contain carbon monoxide (CO) which is colorless and odorless. Breathing it can make you unconscious and can eventually poison you. To avoid breathing CO, follow the preceding safety tips. Exhaust System Rubber Isolator and Loop-Type Hanger - If Equipped Inspect surfaces whenever the vehicle is hoisted for rubber to metal separation or deep cracks. If, however, excessively deep localized cracks are present, or any part of the exhaust system abnormally contacts the underbody hardware, the isolator and/or hanger should be replaced. Cooling System Cooling System Maintenance At the intervals shown in the Maintenance Schedules Section of the manual, the system should be drained, flushed and filled. Inspection Check engine coolant (antifreeze) protection every 12 months (before the onset of freezing weather, where applicable). If coolant is dirty in appearance, the system should be drained, flushed and refilled with fresh coolant as specified. Inspect the entire cooling system for leaks. Check the face of the radiator for any accumulation of bugs, leaves, or other foreign matter. If dirty, clean the radiator core with a garden hose. With the engine OFF, gently spray water from the back of the radiator core. Check coolant bottle tube for condition and tightness of connections at coolant bottle and radiator. 7
