Squeaky belts

Doesn't say to much for the cat house that worked on it 1st... Glad you got it figured out.

I change my belts every 2 years, and check everything else. But I broke a tensioner this year. Six year old truck. So I'm thinking changing the pulleys and tensioner might not be a bad thing. Every 5-6 years.

 

That would have been easy to miss.

 

A noisy belt what I do is take a pry bar works great put it on the Idler pulley center bolt , the squeal is the bearing cage is broken and the balls are rubbing together, the alternator just put it on the housing, the AC put it on the housing, the fan hub put it on the mounting bracket. Some times if you take soap and water especially on an idler pulley if it is bad and you spray the belt before the pulley the offending pulley will actually stop. I have never seen belt dressing do anything positive.
Every trucker should have an infered temp gun, after an hour or so of running the offending pulley should be hotter, the alternator the back end would have been hotter.
If it is your truck you should do tests every so often on what things are when normal then when something is becoming a problem you will notice the difference. Finding some problems like a wheel hub may save an accident.
Just a thought!

 

Replace the belt. My friends chevy 7500 v8 gas squeaks when it starts.

 

Brake fluid in a squirt bottle will will shut a squeaky belt up every time, but nothing helps a bad bearing except a new one. Glad you got it fixed.

 

Did you even read the whole thread? Maybe half of it?
This is apparently where you went wrong Jason......You didn't buy a Chevy 7500!

 

I had to fix the hydraulic system on that chevy 7500.

 

Just curious...how old are you?

 

20, planning to get cdl this month.
