Heater matrix - removal and refitting

Removal
1 With the heater removed from the vehicle as previously described, extract the two securing screws and slide the matrix out of the heater casing.

2 If further dismantling is necessary, cut the casing seal at the casing joint, prise off any securing clips and separate the two halves of the casing.

3 Remove the air flap valves. It should be noted that the lever for the air distribution valve can only be removed when the mark on the lever is in alignment with the one on the gearwheel (see illustration).

4 If the heater matrix is leaking, it is best to obtain a new or reconditioned unit. Home repairs are seldom successful. A blocked matrix can sometimes be cleared using a cold water hose and reverse flushing, but avoid the use of searching chemical cleaners.

Refitting
5 Reassembly is a reversal of removal. Take care not to damage the fins or tubes of the matrix when inserting it into the casing. Refit the heater with reference to Section 11.
