Just paid 750.00 to R&R the timing belt, water pump, tentioner.

I did mine (1998 S70) myself this past spring. I had only done one other timing belt, on my old 1993 940(that was easier because of the engine layout).
On the S70, I used IPD parts with the Continental belt. I also replaced the roller and tensioner just to be sure, because the car had 138K miles on it. You need some larger sized Torx bits for these, can buy them individually at the parts stores. Because I didn't use the old tensioner I didn't have to go through the process of compressing it.
I took me a long time(6 hours or so), mostly becasue I'm inexperienced and was worried about the interference-type engine. Two significant things:
1)I followed the online instructions where you line everything up, but don't actually remove the cranshaft pulley - you just sneak the belt through a small gap down bwlow. It is doable, but was a real pain.
2)I didn't let my tensioner expand enough after putting it on and before trying to turn the engine by hand to check belt/pulley marks line up. The belt slipped and the two cam pulleys and the crank pulley were no longer aligned - worst nightmare. I panicked a little before realizing that you can just turn them back individually until you get them lined up, then put the belt back on and turn the engine very, very slowly by hand at least several rotations to see if you have it right or you feel it stop or bind. I had my wrong, had to remove the belt, turn the crank pulley and try again until I got it right.

Hi,
I've done 2x2 times the Tbelt on two 850. First round with Tbelt only, second time Tbelt+idler and tensioner pulleys. Latest I also changed the water pump as had sqeeking sound with cold starts in winter but couldn't find anything suspicious in the original one.
The hardes piece of cake has been the new Sbelt installation, last time I had to loosen the tensioner bolts to get get the belt over the pulleys, after some days the belt had stretched noticeably. So the new ones are over tight.

If you have the proper tools, the Tbelt is a pain but doable in your garage. The old style hydraulic tensioner needs to be slowly squeezed down, a bar clamp will do the trick. The Sbelt is a one hour job. The Tbelt can be 3 hours or so.
Call your garage and ask for their rates. FCPGroton uses a Continental belt and OEM is Gates.
For the top engine mount bracket, try the salvage yards.

Please answer, we need to know if the advice is good or bad. The 164 has a new home, all I am left with are 2 turbos :)
