Cannot get serpentine belt to stop squeaking.

Two napa belts and replaced idler and both pulley's. It will stop for a day with new belt, but will start back within 24hrs? Any suggestions! I will not drive my truck with a squeaking belt. I even put the old factory belt back on and for a bit it did not make a noise.

Some will undoubtedly disagree but my advice is to get a GM belt

^ thats what i would do. if the factory belt dont sqeak then use a factory belt. i had the same issue with mine. i replaced everything up front when i did the water pump and it has a little sqeak now when its cold

Well that is the only thing I have not done yet! Might as well. Lol

Put some dielectric grease on the belt. That should stop it from squeaking.

OEM tentioner has ridge on both sides of belt to help hold it centered. After market tentioner does not have ridge. My oem tentioner got weak replaced it with a after market Canada made one that just had belt grooves all the way across it. After 3 belts I ordered a oem tentioner and problem solved $70 verses $49. Just what I found on mine.

There is a TSB out about the LLY and LBZ belts squeaking. The alignment can be off with the PS pulley but this was not my case. It was the belt. Removed old belt and recleaned all pulleys with alcohol. New belt part number is 98035628.

Do you have the TSB # & date? im having the same problem on my LBZ.

Belt replacements-

Had problem with different brand belts [GM-Dayco Gates] used for replacement on Duramax, but found that Goodyear GatorBack belt took care of problem, if can you find dealer near you !

The belt is working good for now! I'll give it 24hrs... Then buy a gatorback belt

 

[gassux]

does anyone know what the book time is to replace the belt at the stealership? I did it once and it's just a PITA with the shroud in the way.

Stock belt routing should take 5 minutes. Take off and put on.

 

[dirty_max]

did the oem belt take care of your squeak?

Yes
