276 MAINTAINING YOUR VEHICLE service attendant of this. As long as the engine operating temperature is satisfactory, the coolant recovery bottle need only be checked once a month. When additional coolant is needed to maintain the proper level, it should be added to the coolant recovery bottle. Do not overfill. Points To Remember NOTE: When the vehicle is stopped after a few kilometers (a few miles) 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 accumulation on the radiator and being vaporized when the thermostat opens, allowing hot water 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 coolant freeze point in the system. • If frequent coolant additions are required, the cooling system should be pressure tested for leaks. • Maintain coolant concentration at 50% HOAT ethylene glycol engine 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 has air conditioning, keep the front of the condenser clean, also.
