Coolant Level & Quality Check
1. The engine coolant level should be between the " LOW" and "FULL" lines at normal temperature (20°C (68°F)).^ If low, check for leaks and add engine coolant up to the "FULL" line.
2. Remove the radiator cap from the reservoir.
WARNING: To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot, as fluid and steam can be blown out under pressure.
^ There should not be any excessive deposits of rust or scale around the radiator cap or reservoir filler holed and the coolant should be free from oil.
^ If excessively dirty, clean the coolant passages and replace the coolant.
3. Reinstall the radiator cap.
