3. Close the drain plug and refill the radiator with soft or demineralised clean water. Leave the
radiator cap off. 
4. Run the engine with the heater set on HOT for at least 2-5 minutes (ensuring the thermostat is open).

soft potable water or preferably demineralised clean water 
8. Follow air-bleeding procedures as per vehicle manufacturer’s instructions.
