Mines wobbling back and forth,could this be the pulley or tensioner or both. I know the 12 mm bolts to remove it. How do I put the new one on?. Is there any torque or anything I need to know about. It's all one piece. 94 Volvo 850. hi i done mine recently its easier than it looks esp if you have sm...

here is link,btw i do not think the tensioner ever wears out its just a big spring on a pivot so last pretty much forever,link https://www.ebay.co.uk/itm/FOR-VOLVO-850-960-C70-S70-V70-Fan-Belt-Tensioner-Pulley-V-Ribbed-Belt-Idler/133163449598?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749....

The springs do break and the bearing do seize. If you see the tensioner bobbing up and down when engine is idling it has failed. Replace it ASAP unless you want to toast the motor (serp belt jumps or snaps and takes out the timing belt cover and timing belt). Some of the older tensioners have a Torx...

loveMy850 - post a picture. You may be able to replace the pin or just hard wire a bypass. Picture will help with the best solution. As to the O2 sensor extender - I had a set on the shelf so I tried them out on my X5 while I waited for my replacement cats to arrive. It didn't work. When I put the n...

Model year changes often occured mid-year. This wasn't to do with the countries, just happened to be when the tooling and changes were implemented in different factories. My Belgian made 850 was manufactured September 95, but is a MY96 car - because the equipment and tooling for the MY96 facelift ar...

I bought an ABS module for my '01 XC70 from Ebay, the only place that had the exact same module for less than what the car is worth...works fine

If they have the same Bosch numbers on it and have the same color...it's a direct swap.

But....if they were unprotected all those years....they will need cleaning before install.

Serpentine belt tensioner have nothing to do with timing belt.
It is held with 2 bolts,BUT you need to remove the tension first and slide the serpentine belt from tensioner pulley before you undo those two bolts.

You will need to make a tool for serpentine belt tensioner arm.

In that case....i wouldn't install them.
You will need injectors with same Bosch numbers and color.
They may have higher or lower flow rate...different resistance....and engine would not run properly.
