Use extreme caution when working near the blades of the coolant fan so that you are not injured by a rotating fan blade. As the engine coolant temperature decreases, the fan will automatically shut off. This is a normal condition. 5. Start the engine, top off the radiator with water and then add coolant to the reservoir until the level is between "LOW" and "FULL". 6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fully closed and not leaking. Your engine was originally equipped with platinum-tipped spark plugs. Platinum-tipped spark plugs will last longer than conventional type spark plugs and can be identified by blue lines on the ceramic shell. NOTE: Do not clean or regap platinum-tipped spark plugs.
