Raven997's belt misaligned topic led me to start this. Ever since I did the motor/trans. swap my AC belt has been squealing. The motor/trans. came out of an 01 Tib and I used my original compressor and a new belt. After I got everything together and fired it up, the AC belt squealed constantly with air on or off.
So I put on a new belt, same problem.
So I put on a new compressor, same belt, same problem.
New belt, same new compressor, same problem.
I went through 3 compressors and 4 belts.

You get the idea. I absolutely hate it and cannot get it to stop. Any ideas. Belt dressing hasn't helped either.

 

Does the AC Compressor belt have a tensioner bearing?

and what about the AC Compressor clutch?

And are you using the correct belt? I do not know, but it is possible that Hyundai Changed the mounting bracket for the later engines and the old belt is too long.

 

There is a tensioner and I have replaced it also. I bought a belt for a 98 and then one for an 01 also. The compressor's clutch started as my main area for inspection. But three bad clutches in a row seemed odd. I don't if somehow something came out of alignment maybe. Don't know what would have though. The reason I thought that is because on the 3rd compressor it was quiet but then after driving it for about 2 days it started up with the squealing. mad.gif sad.gif

 

i had a/c belt squeeling for about two weeks.
i changed the belt still squeeled.
i tightened the belt even more and walla no more squeel.

try tightening the belt more. fing02.gif

 

if you go to tight then you will blow out your ac clutch and the tensioner bearing

if you must tigten it slowly over time see if that work or use soap on the belt, bere the korean use wd-40 on the belts laugh.gif

 

That doesn't make it slip?

 

i have heard wd-40 is good for belts, it's what i clean under the hood with, hoses and everything

 

it more or less conditions the rubber makes it alittle softer so it has more grip, i been doing it for years on my rides and the Gov lmao.gif
