I have a 1996 850 gle with 210k miles on it. I have done the timing belt before, no problem. This time I am wondering what else I should replace. I am more familar with the 700/900 series issues.

Should I replace the seals, tensioner or water pump? Any other "while your at it's"?

Thanks.

Thanks to all for the advice. I recently had an timing belt idler pulley go on my 740. The belt cut completely through the housing. Some glue and tape, a new belt and off I go. Thank goodness for non-interference engines.

I suspect I would have had a different experience with my 850 as the valves cut through the pistons. I will replace it all.

If tensioner, pully and roller were replaced at 140K miles, then it's still good. If not, then replace all of them. If in doubt, go ahead and do them. This is peace of mind- if one of these goes, so can the TB. Check condition of seals. If they look good with no weeping, then don't worry about them. If water pump has never been replaced before, you're lucky it lasted this long. It Needs replacing now. You'll need the water pump with it's gasket. Also, the Serp. belt has to come off anyway for the TB. When was the last time it was replaced? Every other Serp. belt replacement, you should replace its tensioner as well. If this hasn't been done, then go for it too. All in all, Serp. belts are lasting as long as TB's, so if you go ahead and replace it, it won't have to be done until 280K miles with the next TB. Good luck!

Thanks, man that sure ups the cost. From FCPGroton the pulleys, tensioner and water pump would be an additional $260.00. Any other vendor suggestions?

I would not suggest 3rd party parts when it comes to water pump. Most pumps only last for 180K miles, you got a bonus!
If you went to a dealer for that list, ouch! Thank goodness FCP is around.

That's about the best I've found. Much cheaper than a busted belt.

Made in Japan's recommendations are pretty much right on the money on that one. You can purchase all of the parts you are looking for from the OE manufacturer for Volvo so there is no reason to either pay top dollar or compromise on quality. At list prices you are in the area of $600.00 for what you are looking at, I just did this entire job yesterday. The only thing that I would not consider replacing at this point is the serpentine belt tensioner. It is two stinking bolts to change that thing out yourself and they always make noise before they go. I have see one tensioner let loose and had the serp belt get into the timing belt and destroy a motor. That was the customers story at least and that is one instance since the white engines came out in '92. But, if you do not want to screw with it then step up and buy a serp tensioner and change it out while you are in there, you're going to have it off to change out the idler pulley anyhow.
