98 v70 xc unusual waterpump issue and tensioner failure

[cn90]

Believe it or not, the Volvo dealer sells the Timing Belt kit (TB, mechanical tensioner, and idler pulley) at a cheaper price than online vendors. Volvo sells the kit for about $120.

So it is a win-win situation when buying Volvo OEM parts, especially in this case.

I use online Volvo in Lisle, IL (suburb of Chicago). They have good price and shipping is quick.

I strongly believe it because I buy from them all the time. Most often than not, the online vendors' loudly advertized 'savings' simply do not compute

I received the new tensioner today and it is virtually the same as the old one except the new one has volvo stamped on it. Still made in slovakia. My question now is the actual adjustment. I understand the procedure, but was wondering the following:
1. There seems to be a discrepancy over which direction to turn the allen wrench. I understand it needs to go past the window and then reenter from the right side and set at the proper temp. I've read both start turning 'clockwise' and 'counter-clockwise' in different posts. Which one is it? I would normally just give it a go, but having one dead tensioner makes me nervous that I'll kill the next one also.
2. Is the steel tab with the allen hole supposed to rotate around the bolt or is it supposed to remain at the same 10 oclock position with the tensioner readjusting as the wrench is rotated.
I thought the belt part was going to be the difficult thing, but this tensioner is my stumbling block and I'm going to try to give it a go between rain storms. Unfortunately no garage here and the car is a Swedish brick right now.

cn90-- I hadn't thought of looking for an all-in-one kit from the dealer... that's a great idea. The price looks great. Is there a specific part number for the kit or a weblink you could point me to for ordering please? Thanks!

@Clockboy

The basic procedure is for the arm to rotate clockwise beyond the correct set point and then adjust the arm to the correct temperature by moving the arm counter clockwise.

To allow the arm to move, you tighten the bolt by hand. Once you set the arm in the correct window, you tighten the bolt with a ratchet.

Thank You. Will give it a go. What could possibly go wrong? Oh, besides blowing up the motor....

To jreed:

Goto http://volvopartslisle.com/ and then find by YM (any part you need)

After adjustment and BEFORE starting your engine. Rotate the motor with a ratchet first to make sure the arm stays where you set it and push on the belt to ensure it moves. I put a bit of anti seize on the bolt so I can remove it easily next time.

That was in the plan. I think I also read run it for 5 minutes and then double check bolt torque and movement. Theoretically since it is a temperature influenced tensioner shouldn't the spring loaded arm creep slightly to the right as the engine bay warms up?

[regent]

Theoretically, yes (I would not sweat it)
If you want to be 110% precise, you could always use a IR Temp Gun and then interpolate the anticipated offset

If you don't have the procedure, see the attached (it's for a S60 but the picture and basics are the same)
You need not worry about femto-inch accuracy
Hope this helps
