15.9 Inlet manifold pre-heater temperature
switch location
Inspect the heater rubber seal for signs of
damage or deterioration and renew if
necessary.
Refitting
8 Refitting is the reverse of the removal
procedure. Ensure that the heater locating
projection is correctly engaged in the manifold
recess. On completion, lower the vehicle to
the ground and refill the cooling system.
Pre-heater temperature switch
Removal
9 The pre-heater temperature switch is fitted
to the underside of the inlet manifold (see
illustration). Either drain the cooling system
or be prepared for some loss of coolant as the
switch is unscrewed.
10 Release the wire retaining clip and
disconnect the wiring connector from the
switch.
11 Unscrew the switch from the manifold and
withdraw it, then plug the opening to prevent
the entry of dirt. If the cooling system has not
been drained, work quickly to minimise
coolant loss.
Refitting
12 Wipe clean the threads of the switch and
of the thermostat housing. If a sealing washer
is fitted, renew it whenever it is disturbed to
prevent leaks. If no sealing washer is fitted,
apply a smear of sealant to the switch
threads.
13 Refit the switch, working quickly if the

cooling system was not drained, and tighten
it. Reconnect the wiring connector.
14 Replenish the cooling system.

removal and refitting 3
Note: The following procedure describes
removal of the manifold with the carburettor.
Access to some of the components
concerned is much improved if the carburettor
is first removed separately and if this is done,
the following procedure should be amended
as required.
Removal
1 Disconnect the battery negative terminal.
2 Remove the air cleaner assembly.
3 Drain the cooling system.
4 Disconnect the accelerator and choke
cables.
5 Slacken the retaining clamps and
disconnect the coolant hoses from the inlet
manifold.
6 Trace the float chamber vent hose and the
full load air bleed hose from the carburettor
down to their metal pipes then unscrew the
nut and bolts securing the pipes to the
cylinder block/crankcase.

disconnect the fuel feed hose from the
carburettor. Place wads of rag around the
union to catch any spilled fuel and plug the
hose as soon as it is disconnected to
minimise fuel loss.
8 Disconnect the vacuum pipe from the
distributor vacuum diaphragm unit and
disconnect the breather hose from the
cylinder head cover.
9 Slacken and remove the brake vacuum
servo unit hose union bolt and disconnect the
hose. Discard the hose union sealing washers
which must be renewed whenever they are
disturbed.
10 Disconnect the idle bypass solenoid
wiring, making notes of the connections so
that they can be correctly reconnected, then
disconnect the wiring from the manifold preheater
switch and heater which are situated
on the underside of the manifold.
11 Undo the single bolt which secures each
manifold support stay to the cylinder
block/crankcase and slacken the bolts which
secure the stays to the inlet manifold (see
illustrations).
12 Make a final check that all the necessary
fuel/breather hoses have been disconnected
from the carburettor/manifold then unscrew
the nuts and bolts securing the manifold
to the cylinder head. Manoeuvre the
manifold out of the engine compartment and
discard its gasket.
Refitting
13 Refitting is the reverse of the removal
procedure, noting the following (see
illustrations):
a) Ensure that the manifold and cylinder
