Water pump must change with timing belt?

It's a very good idea to do so.

Doesn't the timing belt drive the water pumps on these? Water pump fails, timing belt fails, engine is toast, new water pump is cheap insurance.

If I were changing the timing belt I would make the customer sign a waver that I am not responsible for engine damage due to a water pump failure if they opt to not have it changed.

Thanks for the opinions guys. I'll check with my garage next Monday. Since I'd rather have a peace of mind, unless the extra cost of water pumping changing is substantial (>$100), I think I'll elect to do it. The next time I do timing belt change the car will be 180kmi or close to 200kmi, I *guess* the odd for an original water pump to fail before it is high (correct me if I'm wrong). Doing it now is probably a safe and possible money saving measure for the long run. Well hope I'm right.

Best regards,

I don't know how good quality the water pump on the S70 is, but if it fails before 100K i would think that is strange. The water pump on my 91 940 is the original and it has 166K on, no leaks or sounds. I'll guess i'll ghange it on my next timing belt change at 200K. Perhaps the water pump on newer volvos is not so long lived.

A 940 drives the water pump with the accessory belts, much better design IMO, I wouldn't change it until it leaks or gets noisy.

Well I have both timing belt and water pump replaced yesterday. They cost me about $390 with factory parts. Not bad I guess...
