7 Remove the three securing bolts and
withdraw the water pump (see illustrations).
8 A leaking, noisy or otherwise defective
pump must be renewed.
9 Clean the mating faces and obtain a new
gasket for reassembly (see illustration).
10 Refit by reversing the removal operation,
tightening all fastenings to the correct torque
(where specified).
11 Refill the cooling system.
DOHC engines
12 Disconnect the battery negative lead.
13 On fuel-injection models, for access to the
water pump, remove the air inlet hose, plenum
chamber, and air cleaner lid as an assembly.
14 Drain the cooling system.
15 Remove the water pump/alternator
drivebelt.
16 If the pump pulley is to be removed, it is
easiest to do this with the pump in position as
follows. Prevent the pulley from rotating using
a strap wrench (which can be improvised
using an old drivebelt and a large socket and
wrench), and unscrew the four pulley securing
bolts. Withdraw the pulley.
17 Position a suitable container beneath the
water pump to catch the coolant which will be
released as the pump is removed, then
unscrew the five securing bolts and withdraw
the pump from the housing in the cylinder
block (see illustration). Recover the O-ring
seal and discard it; a new one must be used
on refitting.
18 Refitting is a reversal of removal, bearing
in mind the following points:
a)
Ensure that the mating faces of the water
pump and cylinder block are clean and fit
a new O-ring to the pump (see
illustration).
b) Tighten the water pump bolts and where
applicable the pump pulley bolts to the
specified torque.
c) On completion refill the cooling system.
19 Note that on models up to May 1990, the
coolant hoses were connected to the water
pump housing as shown (see illustration).
20 On models from May 1990, the heater
hose (A) and the expansion tank hose (B)
connections were swapped over.
21 If the hoses are disconnected on earlier
models, such as during engine removal, they
should be reconnected as on later models, ie
connect the heater hose to connection B and
connect the expansion tank hose to connection
A. This will reduce the possibility of noises from
the heater matrix due to air in the system.
V6 engines
22 Disconnect the battery negative lead.
23 Drain the cooling system.
24 Remove the fan and viscous coupling.
25 If not already done, remove the pump
drivebelt(s), then unbolt and remove the water
pump pulley.
26 Disconnect the radiator bottom hose and the
heater return hose from the thermostat housing.
27 Remove the three bolts which secure the
thermostat housing to the water pump.
Remove the housing and the thermostat.
28 Remove the twelve securing bolts and
withdraw the water pump. Note that on some
models it will be necessary to remove the
crankshaft pulley and damper to gain access
to the lower water pump bolts (see
illustration).
29 A leaking, noisy or otherwise defective
pump must be renewed.
30 Clean the mating faces and obtain a new
gasket for reassembly. Use a new thermostat
housing gasket also.
31 Refit by reversing the removal operation,
tightening all fastenings to the correct torque
(where specified).
32 Refill the cooling system.
