So my AC belt popped off one day during driving and ended up somewhere down the road....yay.......

so i went and got a new belt and put it on, and i have done everything i can to tighten this belt, and reguardless when i first start up, it just continually slips....and the belt feels tight when i press on it, thats the problem....

done everything i can think of, now i figured i'de see if you guys can help...

i've tried belt dressing, when i sprayed it on the belt, it actually made the compressor slip and start screaming again...go figure...

well any advice is appreciated! thanks!

Did the belt just slip on or did you put slack in the tensioner to put it on?

how did you run the belt over the tensioner or under
i think you ran it under

well thats what happened the first time i changed the belt i put the belt under the tensioner, thats why it ended up somewhere down the road, so when i finally looked at the pics i went OOOpppsss and switched it around with a new belt....still slipping like crazy though

also i slacked the tensioner to put it on and then tightened it to where there was a little play as i could possibly get out of the belt

Maybe your AC compresor have a bearings problem....

Maybe it's the wrong size belt.

And make sure you're using belt dressing that's designed for a serpentine belt. Some belt dressings are only designed for use with v-belts and will cause slipping when applied to a serpentine belt.

definetly the right size belt, went and checked the smaller belt and it wouldn't fit

thanks for the idea on the belt dressing, but the belt for the compressor is a V belt

does it look like the picture here? I think that's not typically called a v-belt even though that's what realoem calls it. I'd refer to it as a serpentine belt...

From what I remember of my 1st Scirocco, the pulley was locking up because the compressor was seizing. In the end the mechanic bypassed the AC pulley.

it rotates, but its tough, how hard should it be to spin it?

remember that the ac compresor have a cluth, it was to spinning, the best test is put the belt, star the car with the ac in on and look to find the slipping cause, if you put wax in the pulleys you can find it more easy because you see with smog in the slipping pulley

how do you do this wax in the pulley thing, never heard of that......

and if necessary i would be interseted in your compressor....how much, and does the TI have the same Comp as the Is?

First i star the engine then use a piece of wax or a cnadle and push it to the drive belt for about a one half of minute... i use this to check for sliping in my blower

well i went out last night after the car cooled down and soaked the clutch with PB blaster, then went out first thing in the morning and hit it with a bunch of lithium grease, and no screaming....i'm sure it's temporary fix, but i'm having my mech look at it tomorrow, if he says it needs to go i'll get in touch with you on the comp.

thanks!

looks like i'm going to need that compressor after all.....

can't get it now due to funding issues, however i will need it eventually. when it comes to the compressor after having someone evac the system it's just a matter of loostening and taking out right? or is it something that i should most definetly have a professional do?

i'de rate myself a 6 in my mechanical abilities, couldn't rebuild a head or an engine but i'm sure i could take one apart, get me?
