Before you start
- Remove the radiator cap only after the engine has cooled to room temperature to avoid steam/hot coolant burns
Procedure
- Close the coolant drain cock of the engine and water pump securely.
- Open the coolant filler and add a mixture of water and coolant at the specified concentration.
- Loosen the air vent plug on the upper section of the thermostat for absolute air bleeding.
- Check heat exchange equipment and other parts for coolant leaks; repair if found.
- Close the coolant filler securely when coolant reaches the full level.
- Crank the engine (pulling stop lever) for approx. 10 seconds, 2-3 times, to bleed the cooling system.
- Check the coolant level.
