Expansion tank and coolant level sensor - removal and refitting
Removal

the cap.
2 Place a suitable container beneath the expansion tank.
3 Disconnect and plug the upper hose.
4 Where applicable, disconnect the coolant level sensor wiring plug.
5 Unscrew the expansion tank securing screws, and tilt the tank so that the coolant runs to the sealed end.
6 Disconnect and plug the lower hose.
7 Drain the expansion tank into the container and remove the tank.
