Question about AC Cars & Trucks
We've tried replacing another pulley
Vehicles are produced with and without AC units. Accordingly there are several length belts available for this purpose.. You may have to get the part number from the dealer spares department.

Yes you can get a shorter belt and bypass the ac. It may be as simple as going to the parts store and tell them you have 2001 jetta no ac. Just keep the receipt.
You should also disconnect the a/c compressor connectors/wires/plugs also, try doing this before you bypass the ac first incase doing so gives you warning lights on the dash board.
Also know that the defrost setting uses the a/c so it will take longer to get the condensation off the inside of the window.

Ignore smart a$$ comments.
Disconnect negative battery terminal.
Remove front right wheel.
Remove splash guard.
Place jack under engine.
Remove left engine support bolts from body.
Remove engine support plate bolts from engine.
Unbolt air conditioner pump and move it out of the way.
Get under vehicle and remove steering pump bolts and move it out of the way.
Remove 6 crankshaft pulley bolts, should be 12mm.
The engine support bracket shoud come off now.
Remove the main crankshaft bolt.
Remove crankshaft dampener.
Remove the timing cover bolts and take off the covers.
Take off the old belt & replace with a new one, don't use a previously used belt.
Make sure the belt tensioner is installed correctly.
Put all the stuff back on.
Get a Haynes manual, pages 3-41.

You didn't mention the alternator, power steering pump, or water pump. In fact, any pulley other than the crankshaft one can have a bad bearing or dry seal. Remove the belt and spin each pulley while listening for any rough noise or squeal. If it was the crankshaft, it might be time to check the oil. Start the engine with the belt off to see if it does squeal. Make sure the noise isn't coming from the radiator fan(s).

I have a 1995 xj6....same problem. I replaced the belts, water pump, and the alternator. Still does it. As I play with the tension on the belt (belt that drives water pump, alternator) it goes away and comes back. If I remove the belt, the metal to metal screech stops. I then, with just the belt, turned the main pulley on the front of the engine, and there was the sound! The main pulley has 2 belts that run on it. Also, 2 pulley tracks. They SHOULD move simultaneously and be super meshed. But the rear one moves on its own under tension until it warms up and I guess, the bushing maybe expands. Now.....how do I fix it??????
