Automatic Transmission Fluid: 10 Engine Coolant: 1, 2 INSPECTION AND MAINTENANCE Engine Coolant Replacement EXAMPLE Open Close 66J191 66J151 64J191 1) When the engine is cool, remove the radiator cap by turning it slowly to the left until a "stop" is felt. Do not press down while turning the cap. Wait until any pressure is released, then press down on the cap and continue turning it to the left. WARNING It is hazardous to remove the radiator cap when the engine coolant temperature is high, because scalding fluid and steam may be blown out under pressure. Wait until the engine coolant temperature has lowered before removing the cap. 2) Remove the reservoir by lifting it up, and drain the reservoir completely. 3) Loosen the drain plug attached to the lower part of the radiator and drain the engine coolant into a suitable container. 4) Reinstall the reservoir and fill it with engine coolant to the "FULL" line. 5) Tighten the drain plug on the radiator, fill the radiator with engine coolant and install the radiator cap. 6) After filling, let the engine idle for about 2 - 3 minutes to get rid of air in the cooling system. Then, stop the engine. 7) Check the engine coolant level in the radiator again. If the level has gone down, add more engine coolant. CAUTION The engine coolant must be replaced with the vehicle on level ground. 7-15 79K21-03E
