- Open the filler cap on the left radiator.
- Position a drip tray beneath the oil/water pump.
- Disconnect lead (arrow) for water pump temperature sensor (1).
- Remove water pump temperature sensor (1), drain off coolant.
- Knead the coolant hose between the coolant outlet and the left radiator (arrow) to force out the remaining coolant.
- Loosen the vent hose fastener (arrow), pull off vent hose.
- Position a drip tray beneath the coolant expansion tank.
