I just had a new belt put on and in the morning it would squeal for just a minute then calm down. When I took it in to have it serviced the mechanic put some kind of belt spray on the belt. Well let just say that did not work because now it has amplified the problem. It squeals constantly when the air conditioner is turned on. I've tried putting baby powder on the belt but it doesn't work. Any suggestions?

TIA

You probably need a new belt tensioner. How many miles and has it ever been replaced to your knowledge?

 

I talked to Disco Mike by email and he seemed to think that may be the problem too. I'll be checking that this evening.

 

hello mate
i had the same prob,sprayed loads of lube on tensioner, no change, got worse when under load ,the prob got solved in 5 mins when i took it to a landrover mechanic to have the cats cut, he opend the bonnet and said (hay another belt running the wrong way!) this also made the waterpump run backwards,i didnt think of checking asit was on the car when i gotit . anywaymay be a bit obvious but hope it helps..........

 

Sparky,
There really isn't much to test on a tensioner. I would suggest you go buy a new one along with a idler pulley and you'll be fine.
By the way, never let anyone put belt dressing on a noisy belt, it will build up a film on the pulleys that will come back and haunt you for years.

Quick follow up on this: Do you consider "Belt Conditioner" (I'm using CRC belt conditioner) the same as "belt dressing"?

Also, if you get something like that on the belt, and it's a bad idea, how to remove? Brake Cleaner?

 

A quick follow up on a 7 year old post, timely very timely

 

Thanks for the help @drowssap! j/k

for anyone caring - don't ever use the "Belt Conditioner" - left crap on my jockey pulley

new Gates belt from O'Reilly's solved it - now she purrs...
