MAINTAINING YOUR VEHICLE 307 bugs, leaves, etc. If dirty, clean the radiator core by gently spraying water from a garden hose at the back of the core. Check the coolant bottle tubing for condition and tightness of connection at coolant bottle and radiator. Inspect the entire system for leaks. With the engine at normal operating temperature (but not running), check the coolant pressure cap for proper vacuum sealing by draining a small amount of coolant from the radiator drain cock. If the cap is sealing properly, the coolant will begin to drain from the coolant bottle. Do not remove the pressure cap when the cooling system is hot. WARNING! You or others can be badly burned by hot coolant or steam from your radiator. If you see or hear steam coming from under the hood don't open the hood until the radiator has had time to cool. If you open the hood and see steam or hot coolant escaping from the radiator, don't touch anything. Get away quickly. Never try to open a pressure cap when the radiator is hot. Cooling System Maintenance At the intervals shown in the Maintenance Schedules section of this manual, the system should be drained, flushed and refilled. See your authorized dealer for proper cooling system maintenance. 7
