DOHC models
6Disconnect the battery negative lead.
7To provide additional clearance when
removing the cooling fan shroud assembly
(which is removed from below the vehicle),
apply the handbrake, then jack up the front of
the vehicle and support it securely on axle
stands (see “Jacking and Vehicle Support”).
8Disconnect the wiring plug(s) from the
motor(s), and where applicable, unclip the
wiring from the fan shroud.
9Unclip the expansion tank hose from the
fan shroud.
10Unscrew the two nuts securing the fan
shroud to the top of the radiator, then tilt the
top of the shroud away from the radiator, and
lift the shroud to release the lower securing
clips. Withdraw the assembly from below the
vehicle.
11To remove the fan blades, prise the
securing clip from the end of the motor shaft.12The motor can be separated from the fan
shroud by unscrewing the three securing nuts
and bolts.
13Where two cooling fans are fitted, both are
secured to the shroud in the same manner.
14Refitting is a reversal of removal, but
when fitting the fan blades, ensure that the
drive dog on the motor shaft engages with the
slot in the rear of the fan blades.
On CVH models, the cooling fan switch is
located on the right-hand side of the
thermostat housing (see illustration). On
DOHC models, the switch is located in the
end of the thermostat housing.
Removal and refitting of the switch is as
described for the temperature gauge sender.
Removal
1With the engine cold, slowly unscrew the
expansion tank cap to release any remaining
pressure from the cooling system. Remove
the cap.
2Place a suitable container beneath the
expansion tank.
3Disconnect and plug the upper hose.
4Where applicable, disconnect the coolant
level sensor wiring plug. 5Unscrew the expansion tank securing
screws, and tilt the tank so that the coolant
runs to the sealed end.
6Disconnect and plug the lower hose.
7Drain the expansion tank into the container
and remove the tank.
8Where 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).
Renew the seal if necessary. Note that the
sensor can only be fitted in one position (see
illustration). Refitting
9Refitting is a reversal of removal.
10On 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.
Removal
1On SOHC models, the temperature gauge
sender is located on the front left-hand side of
the cylinder head, just in front of the inlet
manifold. On CVH models, the sender is
located on the front face of the inlet manifold,
next to the thermostat housing. On DOHC
models, the sender is located at the front of
the inlet manifold (see illustration).

pressure from the cooling system, then refit
the cap.
3Disconnect the wiring from the sender
terminal (see illustrations).
4Unscrew and remove the sender, and
temporarily plug the aperture.
Refitting
5Refitting is a reversal of removal, but smear
a little sealing compound on the sender unit
threads before fitting.
6On completion, check and if necessary top-
up the coolant level.
Removal
1Disconnect the battery negative lead.
2Remove the securing screws and unclip the
lower and upper steering column shrouds.
3Remove the four securing screws and
withdraw the instrument panel surround. Note
that the bottom right-hand screw is covered
by a plastic panel which must be prised out.
4Remove the passenger side lower facia
panel.
5Where necessary for improved access,
detach the two vent hoses from the left-hand
side of the heater, then detach the lower ends
of the two control cables from the heater by
removing the retaining screws (see
illustration).
6Unscrew the three securing screws, and
remove the heater control panel by sliding it
through the facia panel and withdrawing it
downwards. Disconnect the wiring from the
control panel illumination bulb.
7If necessary, the bulb can be removed with
its holder.
Refitting
8Refitting is a reversal of removal, bearing in
mind the following points.
9When reconnecting the wiring to the control
panel illumination bulb, wrap insulating tapearound the wiring loom over a length of
approximately 330.0 mm (13.0 in) starting
from the bulbholder. Route the loom, ensuring
that it is located in the two retaining clips,
bend it over and secure it to the bulbholder
with insulating tape as shown (see
illustration). This procedure will prevent the
wiring loom from chafing against the heater
control levers.
10When reconnecting the control cables to
the heater, move the control levers on the
control panel to the fully up position, then
attach the cables to the clips on the heater.
The cable ends should project from the clips
by between 0 and 4.0 mm (0 and 0.16 in). The
cables are adjusted automatically by moving
the control levers fully downwards. It is
possible that considerable resistance may
have to be overcome when moving the control
levers.
Removal
1Disconnect the battery negative lead.
2If the coolant is still hot, release the
pressure in the system by slowly unscrewing
the expansion tank cap. Place a thick rag over
the cap to prevent scalding as the pressure is
released.
3Note the location of the two heater hoseson the engine compartment bulkhead, then
disconnect and plug them (see illustration).
Alternatively, the hoses can be secured high
enough to prevent the coolant from draining.
4To prevent unnecessary spillage of coolant
when the heater unit is removed, blow into the
upper heater pipe until all the coolant has
been expelled through the lower pipe.
5Remove the two securing screws and
withdraw the heater pipe cover from the
bulkhead (see illustration). Recover the
gasket.
6Working inside the vehicle, remove the
passenger side lower facia panel.
7Disconnect the ends of the two control
cables from the heater by removing the two
retaining screws.
8Detach the five vent hoses from the heater.
9Unscrew the two mounting bolts, and move
the heater to the rear until the pipes are clear
of the bulkhead, then withdraw the heater to
the left. If necessary, remove the lower facia
bracket (see illustration).
Refitting
10Refitting is a reversal of removal, but
adjust the control cables by moving the levers
on the control panel to the top and then the
bottom stops. Considerable resistance may
be encountered when moving the levers
towards the bottom stops, which should be
overcome.
11On completion, top-up the coolant level.

remove the front bumper.9Disconnect the fan wiring connector at the
side of the condenser.
10Remove the three securing bolts and
withdraw the fan assembly. Turn the frame to
position the fan wiring on the dehydrator side
to avoid damaging the wiring. Take care also
not to damage the condenser fins or tube.
11To remove the fan blades from the motor,
remove the retaining nut and circlip. The nut
has a left-hand thread, ie, it is undone in a
clockwise direction.
12With the blades removed, the motor can
be unscrewed from the frame.
13Reassemble and refit in the reverse order
of dismantling and removal.
