change water pump at time of changing timing belt?

Standard procedure is to check if its ok and if no wear on the bearings or leaks are spotted its not changed.

Greetings Niels

It makes sense to do both jobs at the same time IF the pump shows signs of wear. The work necessary to do the belt is essentially the same as to replace the pump but I would be inclined to wait until the next belt change and do the pump then regardless of what it looks like. But I'm kind of a cautious guy.

Water pumps on the whole last week- certainly past 100k. You may wish to check it carefully and perhaps leave it. Tensioner rollers and idler are much more important- they dont last quite as well.

Personnally, for the exta £60 I always change the lot given that you dont get any 'slack' if the belt comes off / fails on the 5 cyl. It will lunch the engine entirely.

I changed the pump as well, at the 140K miles service, just to be on the safe side... The old pump didn't show any signs of wear at all, but a new original Volvo pump cost me around $100 ( in Denmark ) and that's a cheap insurance against pump failure if you ask me....

Since it is driven from the timing belt and it's failure could cause serious problems elsewhere I would follow common practice and change the pump.
