MAINTAINING YOUR VEHICLE 333 When additional antifreeze/coolant is needed to maintain the proper level, it should be added to the coolant bottle. Do not overfill. Points To Remember NOTE: When the vehicle is stopped after a few miles (kilometers) of operation, you may observe vapor coming from the front of the engine compartment. This is normally a result of moisture from rain, snow, or high humidity accumulating on the radiator and being vaporized when the thermostat opens, allowing hot antifreeze/ coolant to enter the radiator. If an examination of your engine compartment shows no evidence of radiator or hose leaks, the vehicle may be safely driven. The vapor will soon dissipate. • Do not overfill the coolant recovery bottle. • Check antifreeze/coolant freeze point in the radiator and in the coolant recovery bottle. If antifreeze/ coolant needs to be added, contents of coolant recovery bottle must also be protected against freezing. • If frequent antifreeze/coolant additions are required, or if the level in the coolant recovery bottle does not drop when the engine cools, the cooling system should be pressure tested for leaks. • Maintain antifreeze/coolant concentration at 50% HOAT antifreeze/coolant (minimum) and distilled water for proper corrosion protection of your engine which contains aluminum components. • Make sure that the radiator and coolant recovery bottle hoses are not kinked or obstructed. • Keep the front of the radiator clean. If your vehicle is equipped with air conditioning, keep the front of the condenser clean, also. • Do not change the thermostat for summer or winter operation. If replacement is ever necessary, install 7
