water pump, remove the air inlet hose, plenum
chamber, and air cleaner lid as an assembly.
14Drain the cooling system.
15Remove the water pump/alternator
drivebelt.16If 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.
17Position 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.
18Refitting 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.
19Note that on models up to May 1990, the
coolant hoses were connected to the water
pump housing as shown(see illustration).
20On models from May 1990, the heater
hose (A) and the expansion tank hose (B)
connections were swapped over.21If 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.
