MAINTAINING YOUR VEHICLE 241 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 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 bottle. • Check coolant freeze point in the system. • If frequent coolant additions are required, or if the level in the recovery bottle does not drop when the engine cools, the cooling system should be pressure tested for leaks. • Maintain a coolant concentration of a minimum of 50% ethylene glycol Extended Life Coolant and high quality water with recommended antifreeze for proper corrosion protection of your engine cooling system that contains aluminum components. • Make sure that the radiator and coolant 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. • Do not change the thermostat for summer or winter operation. If replacement is ever necessary, install ONLY the correct type thermostat. Other designs may result in unsatisfactory coolant performance, poor fuel economy, and increased emissions. Hoses And Vacuum/Vapor Harnesses Inspect surfaces of hoses and nylon tubing for evidence of heat and mechanical damage. Hard or soft spots, brittle rubber, cracking, checking, tears, cuts, abrasions, and excessive swelling indicate deterioration of the rubber. Pay particular attention to the hoses nearest to high heat sources such as the exhaust manifold. Inspect hose routing to be sure hoses do not touch any heat source or moving component that may cause heat damage or mechanical wear. 7
