valve and free the cable outer from the
retaining clip.
24 Slacken and remove the bolt securing the
heater valve mounting bracket to the engine
compartment bulkhead.
25 Either drain the cooling system or clamp
the coolant hoses on each side of the coolant
valve to minimise the loss of coolant.
26 Slacken the hose retaining clips, then
disconnect both hoses from the coolant valve
and remove the valve from the engine
compartment. Mop up any spilt coolant
immediately.
Refitting
Heater unit
27 Refitting is a reverse of the removal
procedure, noting the following:
a)
Ensure that the heater ducts are securely
connected to the unit so that there are no
air leaks or gaps.
b)
Check the operation of all heater cables
before refitting the facia, ensuring that the
relevant component moves smoothly from
the fully open to the fully closed position.
If necessary, adjustments can be made by
releasing the relevant retaining clip and
repositioning the cable outer.
c)
Ensure that the heater hoses are correctly
reconnected and are securely held by the
retaining clips.
d)
Tighten the heater lower mounting nut to
the specified torque setting.
e)
Refill the cooling system as described in
Chapter 1.
Heater matrix
28 Refitting is a reverse of the removal
procedure.
Heater blower motor
29 Refitting is a reversal of the removal
sequence, noting the following:
a)
Ensure that the foam rubber seal is
refitted correctly so that the blower
motor-to-bulkhead aperture is closed off.
b)
Tighten the blower motor mounting bolts
to the specified torque setting.
c)
Ensure that the air recirculation cable and
flap functions correctly before refitting the
glovebox. If necessary, adjust by releasing
the cable retaining clip and repositioning
the cable outer.

31 Refitting is a reversal of the removal
procedure. On completion, check the heater
cable operates smoothly and replenish the
cooling system.
11 Heater ducts and vents -
removal and refitting
3
Removal
Facia ducts
1 Remove the facia.
2 The ducts are mounted on the facia
assembly and can be removed individually,
once the retaining screws have been
removed.
Heater unit ducts
3 The left-hand heater unit to blower
motor duct is removed as described in
paragraphs 15 to 17 of Section 10.
4 To remove the right-hand duct, first remove
the facia. Slacken and remove the retaining
screw which secures the right-hand end of the
duct to the mounting bracket and release the
radio aerial from the retaining clips on the
underside of the duct. The duct can then be
manoeuvred out of position.
5 Removal of the lower ducts which supply
air to the rear passenger footwells is a
complex job, requiring the removal of the front
seats, centre console and the various trim
panels so that the floor carpet can be peeled
back, and is therefore not recommended.
Centre console vents
6 Remove the centre console.
7 The vents can then be unclipped from the
rear of the front console section and removed.
Facia vents
8 The adjustable face-level vents can be
removed by prising them gently out of the
facia until the clips are released, taking care
not to mark the facia.
9 The door window demister vents, fitted to
the sides of the facia, can also be prised out
of position once the relevant door has been
opened.
Refitting
10 Refitting is a reverse of the removal
procedure.
12 Heater controls - removal,
refitting and adjustment
3
Removal
1 Remove the heater unit.
2 Disconnect the heater control cables from
the heater unit and unclip the control panel.
Remove the panel assembly complete with
cables (see illustrations).
Refitting and adjustment
3 Refit the heater control panel to the heater
unit and reconnect the necessary control
cables to their original positions.
4 Check the operation of the control cables,
ensuring that they operate smoothly and
move the necessary component from the fully
open to the fully closed position. Adjustments
can be made by releasing the cable retaining
clip and repositioning the cable outer.
5 Once the necessary control cables are
functioning correctly, refit the heater unit.
