I am planning on doing the timing belt change this weekend. What other items might I want to have on hand while I am doing this? Tensioner pulley? Water pump?
Of course if anyone has a good tip about the job, I'd be grateful.
Thanks,
Kirk

At a minimum, I would replace the timing belt and the hydraulic tensioner. For a little extra peace of mind, if you don't mind spending a bit more, also replace the water pump, the tensioner pulley, and the idler pulley. No harm to replace the serpentine belt also.
I did my belt last summer (at 70k), and also replaced the hydraulic tenioner and water pump, but not the pulleys. Next time, I'll do the pulleys also. My original water pump looked fine, with no play in the bearings at all. In fact, I was tempted to put the original pump back in, as it looked more robust than the replacement part (made by HEPU - non OEM). Next time, I'll probably also get the OEM water pump for a few dollars extra.

Should check all the pulley and tensioner to ensure that they are still in good shape until the next t-belt change. I recently replaced the t-belt and the t-belt tensioner. Water pump in 850 is not an issue unless it leaks. Otherwise, no need to change it.

Hi Ho, Did you replaced the t-belt yourself ?

Ken,
I did not do it myself. This is the only item that I still don't have the gut to do it myself. I have done most of the work on my 850 but this one. I wish that I can do it someday by then I will be totally free from the dealer. I asked dealer to check the belt tensioner and pulley. They replaced the t-belt tensioner along with the serpentine belt too. This is my 2nd t-belt change, almost 140k miles.

There have been posts to this site indicating that others have had water pumps seize and then had to pay big bucks for an engine rebuild...

Not as often as the t-belt tensioner gone bad. Moreover, before the seize happening, there are sign of losing coolant via the water pump.
However, this is all personally decision to replace which component along with the t-belt. At least, from my experience, 850 water pump is much more durable that others. Many posts from the Volvospeed.com indicated that there is not necessary to replace the water pump along with the t-belt change. Final decision is still on the hand of the car owner.

My Indy (exclusively Volvo) shop did the idler pulley and hydraulic tensioner but not the water pump with the second (140,000 mile) change. As noted, the Volvo water pump is extremely robust. The car is no Honda.
I also asked for a new serpentine belt since it has to come off anyway and it's only a few bucks more.

Don't know what your mileage is, but my Indy tells me it is a good idea to replace the water pump every other timing belt change. If the water pump seizes, there goes your timing belt and then valves and pistons try to occupy the same spaces...
