Default Belt Tensioner Broke Off!

So my belt tensioner broke off, tore up my belt, and damaged my CV Boot in the process. Dealership says $1400+ to fix How difficult of a task is this? I'm mechanically inclined. Any special tools required? Any help would be great. Thanks!

Call up your local parts store. Everything you need is fairly cheap compared to the $1400 BS quote you got

That makes sense...that's why I can't find just the boot!

Didn't think about that...but remove the wheel well? I'll have to take a look when I get off. Thanks for the tips guys!

Right now I'm forced to drive my Skylark. Dirty, smudged up primer, with rust poking through and no A/C in 105 degrees!

nobody seems to be able to help me!!! I have a 2006 chevy impala SS with the 5.3 liter v8. I have the pulley to this part in your picture that needs to be replaced and I have no idea how to do it!!!!! I have at this point taken off the tensioner spring(doesn't appear to be compromised at all) took two 15 mm bolts to get it off this was of course after I had released the tension by taken the shredded belt off that led me to the damaged pulley in the first place. Now that I have the spring off I'm still just trying to figure out how to replace the pulley. Any info will help. Thanks in advance

The pulley bolts onto the tension bracket with a torx bit bolt. With the proper bit and a 3/8" ratchet wrench, the bolt holding the pulley just backs out, then take the pulley to a parts store and have them match it up.

What's the best way to get a stuck pulley off then tensioner besides cutting it?

Unthread the bolt holding the pulley to the tensioner bracket. If you strip the torx threads, then put a 3/8" or 1/2" nut over the torx bolt head, fill the center of the nut with weld, wait a couple of minutes after the nut stops being red, and use the nut to unthread the torx bolt.

Once the torx bolt in the center of the pulley is removed, the pulley should slide off the boss that it is resting on. If not a little penetrating oil, persuasion with a pry bar, or a pulley puller should help remove it - all the ones I have taken apart the pulley came right off once the bolt was out.

Yeah sorry that happened. Mine did too... and when the belt snapped it took a 3rd off my radiator. I get why the dealer charges what they do... its a rough job. Get a 6" hose clamp to secure the spring when you install to make the belt fitment easier. That hose clamp will allow you to keep the spring compressed without special tools and a 3rd arm. Works great when you need to do the belt or other accessories on the car as it makes belt movement easy. Just secure the belt with some painters' tape to make sure you don't loose your orientation around the pulleys.
Cheers.

Can I ask why you aren't just getting the whole belt tensioner as one assembly? When mine failed... I had to. It broke in half. I would suggest that... as they are prone to failure and you DO NOT want to go thru this again or loose your perfectly good radiator like I did.
