5 Disconnect the top mountings, as
applicable, then lift the radiator, complete with
cooling fan, from the car - taking care not to
damage the matrix (see illustration). The
base of the radiator incorporates pins which
locate in rubber mountings.
6 If necessary separate the cooling fan, with
reference to Section 6.
Refitting
7 Refitting is a reversal of removal; fill the
cooling system as described in Chapter 1 on
completion.

removal and refitting

Removal
The radiator cooling fan may be removed
with the radiator, as described in the
preceding Section, and then separated.
Alternatively it may be unbolted or unclipped
(as applicable) from the radiator after having
removed the front grille and crossmember,
and disconnected the wiring. The motor can
be unbolted from the frame and then the fan
removed from the motor (see illustrations).
No spare parts are available for the motor.
Refitting
Refitting is a reversal of removal.

Radiator cooling fan
thermoswitch
Removal
1 The thermostatically controlled switch for
the cooling fan is screwed into the radiator
side tank.
2 Drain the cooling system as described in
Chapter 1.
3 Disconnect the switch wiring and unscrew
the switch from its location.
Refitting
4 Refitting is a reversal of removal, but use a
new sealing washer if necessary. Fill the
cooling system as described in Chapter 1 on
completion.
Coolant temperature sensor
Removal
5 The coolant temperature sensor may be
located in the left-hand end of the cylinder
head, on or beneath the thermostat housing,
or below the distributor, according to engine
type (see illustration). On some engines, two
sensors may be fitted, one for the temperature
gauge and another for the engine
management system. Testing should be
carried out by an auto-electrician or by
substitution with a known good unit.
6 Partially drain the cooling system (see
Chapter 1) to below the level of the sensor
unit.
7 Disconnect the wiring from the sensor and
unscrew it from its location.
Refitting
8 Screw in the new unit, using a smear of
sealant on the threads or a new sealing
washer, as applicable. Reconnect the wiring.
9 Top-up the coolant level (see Chapter 1 and
“Weekly checks”).
Coolant level sensor
Removal
10 The coolant level sensor is located in the
radiator right-hand side tank on XV, XW and
XY series engines and in the expansion tank
on all other engines (see illustration). The
switch is float-operated and actuates a
warning lamp in the event of a low coolant
level.
11 The sensor is removed by unscrewing it
from its location after disconnecting the
wiring.
Refitting
12 Refitting is a reversal of removal using a
new sealing washer where necessary.
