Find a different rebuilder or your belt is to tight. Check tensioner and belt size.

Something sounds like it is out of alignment. Usually it's electronics that fail in them not mechanically. Could also be cheesball rebuilds without new bearings that could cause a mechanical failure.

Well, it turns out my tensioner pulley was dangerously loose, called most stores in the area, my mechanic said he called most stores in the area, and no one had it in, is there a certain kind I need, or could I interchange from a different car? As I need this VERY soon. Also, would it be a good idea to change the belt at this time, and does a regular '87 Regal belt work?

A new tensioner pulley is available aftermarket for $13. Doesn't look exactly stock but the thing works fine.

Make sure the bolt and mount is good. Don't want the new one to go fubar on ya.

Belt is also available in parts houses and I don't think it fits regular Regals.

I like the GM belt when I think of ordering them.

Do you mean any parts store, or one specific like kirbans that sells them?

I think you'll find that you can replace a bad bearing in the pulley with a new one.Just unscrew it,press out the old bearing,press in a new one,and reinstall,nice and tight.The bearing number is 6203,I believe[you'll see it when you pull the bearing].It's easy and relatively cheap.If you don't want to do the bearing,Dayco makes a replacement pulley.

The bearing is common as da Kid said. If you have the tools and press just replace the bearing.

However I was in a hurry and just went and got the pulley with new bearing for $13 which didn't really help my squeak but is still on my car. Turned out to be the belt in my case.

Just ask any parts counter they will have it or can get it quick enough for you.

Don't buy ANYTHING from Dayco! They screwwed me good on my park avenue. I bought a supercharger and accessory belt for the car and in less than 1000miles the supercharger belt came apart and tore a huge hoel in my hoodliner.

After some arguing Advanced Auto replaced the belt, only to have it fail again. I replaced it with a Kelly Springfield and have had no problems. Come to find out the Kelly Springfield belt was a 1/2" longer. When I took the supercharger blet off I found that the main accessory belt had done the same.

Dayco had refused to replace the hoodliner on my car because I got the parts store to replace the belt. What a bunch of crroks! They refused to contact their vendor to confirm the situation or take any action involving compensation. Now that I've got two more of thier belts that have made like weedwhackers on my hoodliner, they are still refusing to compensate me, and now with no good reason.

Yeah my pulley is a Dayco and works ok.

I have given up on their belts however, they kinda suck.

No that is a complete tensioner.

Dayco sells a replacement pulley with a new bearing in it.

Not the whole mount just the pulley.

If your problem is the pulley itself the Dayco should fix it. I would check the bolt that holds the pulley to the mount for sure too. You don't get the bolt with the pulley for the $13. All you get is the round pulley with a bearing in it.

The whole tensioner assembly is available from GM at big $$$. That would be the mount and the pulley assembly.

OK, thanks alot, the problem is going to require the bolt, and maybe the whole assembly too, as it no longer keeps tension on the belt. My mechanic said the spring was sprung, so I think I may need the whole assembly. ;(

Personally for a daily driver I would go to GM and pay the $200 or so for a brand new one and also a new bolt.

For a part time car I would email Brian Weavy and Mike McCoy and check out pricing on a good used one. Make sure you specifically tell them you need the bolts too!

Good luck.

Actually I figured you had it fixed already anyway. This might save a few bucks.


Don't forget to tell him you need the bolts or you prolly won't get them! Very important for you with your problem.

Good luck!
