Thats great thanx very much for your help im definitly going to change the water pump when i do the cambelt
Changing water pumps when you change the cam belt is more applicable to 4 pot cars where the cam belt also drive the water pump. You have a 'fan belt' to drive your water pump on a V6
So, at 80k miles do I need to or should I replace the pump when I change to cambelt on my 3.2 V6?
If its not been changed already, at 80k you should generally change it. Only costs 25 quid and if you later need to do it you'll have a couple of hours additional labour on top.
(In the case of 4 pots it is more critical though, as if the pump fails, it will likely take out the cambelt resulting in serious engine damage)
