2 The control lever mounting platform can be
removed after extracting its fixing screws.
3 The coolant control valve can be removed
after extracting its fixing nuts.
4 Unscrew the screws which hold the heater
matrix in the casing and then slide the matrix
from its location.
5 If the matrix is leaking, do not attempt a
repair, but obtain a new one. These are
usually obtainable on an exchange basis from
radiator repairers.
6 The heater casing can be separated after
prising off the clips and removing the bolts.
The blower motor/fan can then be lifted out.
7 Reassembly is a reversal of dismantling, but
set the cables to give complete range of travel
between open and closed positions of the flap
valve or coolant valve concerned.
