........ remember with V6's the waterpump should have been changed along with the belt, tensiors and pulleys.
......

Why's that?

Not so critical on the V6.
On the 4 pot the water pump is driven by the cambelt so it is critical to change the pump with the belt. A water pump failure there will cause severe damage!

On the V6 the water pump is driven off the aux belt.
It is, however, wise to change the water pump at least every other cambelt change.
You strip down to it to do the cambelt so it is simply 5 mins extra work (and £25)  for the total piece of mind.

Because if the water pump fails....so does the cambelt! (i think?) - Its not expensive and worth doing with a belt change.

I cannot remember the exact technical reason why you replace it, but someone who knows more will be along in a min....

** edit. oh they have! lol

I must change mine with my next belt change...

Not the case on the V6, it would need to be a catastrophic failue to take the cambelt out as its driven by the aux belt.

The water should be changed every time on the 4 pots as its cambelt driven....

v6 water pump is NOT driven by cambelt. 4 pot one is.

For sake of £20 + VAT on v6, when doing the cambelt, do water pump seeing as its stripped down that far. On 4 pot, change water pump coz it is driven by cambelt.

I had a feeling that's what the answer was going to be!  ::)
But I already knew my water pump was 'fan belt' driven and not cam belt driven.

Just to add to Dave's warning on 4 pots.....my 4 pot had its cambelt done at 42k when i bought it (vx dealer i bought it off didnt do it, but then paid me for having it done at another vx dealer) About 10k miles later i had a 'cracking' noise coming from engine compartment, turned out to be water pump bearing going.....so needed new water pump and a new cambelt again.....make sure tensioner is changed as well.....not sure if mine was changed at cambelt change..but i had to have the tensioner changed shortly afterwards.....which meant another new cambelt. Supplying dealer paid for the orig cambelt change and all the rest of the changes were done under warranty....woulda cost me mega bucks at vx prices to have it all sorted if not.
