Expansion tank and coolant level sensor - removal and refitting
Removal
1 With the engine cold, slowly unscrew the
expansion tank cap to release any remaining
pressure from the cooling system. Remove
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.
8 Where applicable, the coolant level sensor can be removed from the tank by unscrewing the collar from the sensor, then withdrawing the spacer, sensor and seal (see illustration).
15.8a Removing the coolant level sensor from the expansion tank

15.8b Fitting the coolant level sensor
Refitting
9 Refitting is a reversal of removal.
10 On completion, top-up the coolant level to the maximum mark, then refit the expansion tank cap and run the engine at a fast idling speed for several minutes. Check the expansion tank for leaks, then stop the engine and if necessary top-up the coolant level.
