10 Water pump (V6 engines) -
removal and refitting
4
Note: Due to the layout of the V6 engine and
the limited space available in the engine
compartment, access to most components is
extremely limited and may present unforseen
difficulties. Read through all the relevant
procedures and familiarize yourself with
what’s involved before proceeding.
Note: Refer to the warnings given in Section 1
of this Chapter before starting work.
Removal
1 Drain the cooling system as described in
Chapter 1.
2 Remove the timing belt and timing belt
tensioner as described in Chapter 2, Part B.
3 Undo the nine bolts securing the water
pump to the engine front plate, noting that
two are of a different length than the rest (see
illustration).
4 Withdraw the water pump and recover the
large sealing O-ring.
5 Thoroughly clean the mating faces, locating
dowels and O-ring recesses.
Refitting
6 Refitting is a reversal of removal, but use a
new sealing O-ring, and tighten the retaining
bolts to the specified torque. Refit the timing
belt and tensioner as described in Chapter 2,
Part B, and refill the cooling system as
described in Chapter 1.
