Well I certain saw different life on water pumps on the other posts than was my experience with my 82 245. I generall only got about 50K out a water pump but that could be due to the fact that I had two belts on the water pump and alternator and this put alot more strain on the bearings and seal. There is only one belt on the water pump on each of my 940SEs so I hope to have a longer life on these water pumps. Water pumps are cheap go ahead and change it. That's my $.02.

Replaced waterpump on my -77 B19A at 200,000km (started leaking through the axle gasket) , -89 B230K has now 270,000km (170,000 miles) and original waterpump. I'd leave the pump, although the change job is not very hard either...

A lot of water pumps on a lot of car makes go out at about 60 to 70,000 miles. Volvos may last longer than average, I don't know.

I had a water pump on my daughter's Mazda that did not leak, but the car was running hot and losing coolant. Pulled the pump and the rotor was completely corroded away! So you never know from appearances.

Water pumps are cheap and easy to replace. I would do it while I was in there for peace of mind.

My opinion: If it isn't leaging, wobbling, or screaming, leave it alone.
When you change the timing belt, see if it has any play in it. If so, replace it.
Now, if someone other than you will be driving, and you want to make sure they don't have a problem, then replace it. Or if you are about to embark on a trip, you may want to replace it.
Water pumps usually leak or make noise before they give up.

I second mudduck's approach. The original water pumps on my '88 and '92 245's lasted well over 150K each. Unless you have known leaks or other W/P problems, just get a pump and gasket to keep on hand for when it *does* start to go on you. If you're really proactive, wait until your next timing belt change to throw the new pump in.

But - before you put the new rad in, do a thorough flush of your cooling system.

Remember to replace those two little hoses at the rear of the engine which go to the heater core... miserable to get at, but they are definitely life-limited parts. Change 'em before you need to.

Replaceing the radiator does not make changing the water pump THAT much easier a little granted... but to me not enough to warrent spending the money on a water pump that is not leaking...of course I'm very cheap...

You've heard "if it ain't broke don't fix it"?...my motto is "if you can get by with it broke... run it till you can't"....unless it's the wifes car... (whole other set of rules for the wifes car)

well...the car has 11 years on it so i suppose you could change it. On the other hand if it's not leaking...and it's running fine...then really no reason to change it.

the answer would be it depends on what you think the water pumps condition is in.

I personally would leave it alone until it started at least leaking a bit or something....it may take you easily to 100k or more

If it's the original pump, replace it while you're doing all the rest. It's probably living on borrowed time.
