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.

SOURCE: shorter serpentine belt on 2001 jetta tdi

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.

SOURCE: 1999 dodge durango 5.9 v8 loud squealing noise

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).

SOURCE: noisy water pump pulley,alternator pulley..timing belt tensioner

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??????

Is there anyway to by pass the AC unit, when installing a new belt ?


There may be a compressor eliminator pulley kit for your car. Or if your compressor is locked up, replace the compressor with a used or rebuilt just for the sake of bearings. Or if a belt will clear with the compressor gone (or installed) , measure from your mark on one apex to the next pulley/ idler with the tensioner compressed more than halfway and add that distance to the remaining belt length between the marks and ransack the earth for one. Start with Graingers. Or try your parts supplier who took an oath not to try to match anything up. Here you'll have to ask to use the bathroom, and while in the back start measuring belts.

Can i use a smaller serpentine belt if i bypass the air conditioning unit?


In some cases this can be done-but you do not mention the engine you have-also, there are bypass pullleys that some sellers have for just such circumstances, google bypass pulleys for your engine-you sometimes can do this yourself if you keep in mind the rotation of all pulleys has to remain the same,

Talk to your automotive supply. My understanding is that a Non-AC belt will run right thru the area where the AC pulley is. You can get a bypass pulley that will allow you to avoid the AC and it's pulley and a specific belt for that setup.

Serpentine belt, correct? You'll need to find the correct belt size for an Exploder w/out AC. You may need to remove the AC compressor, if the pulley is in the way.

Could it be the pulley on the AC that's squealing? Use a mechanic's stethoscope to locate the squeal. If it is the AC, you can get a belt that is shorter, and bypass the pump, since it doesn't work anyway. Try some belt dressing first. When the engine is running, just spray it on the inside of the belt.

Have a 1990 Jeep Laredo w/I6 4.0 and AC. Need Replacement belt.


The compressor has become an integral part of the system to the point that there is no listing for optional no a/c. Looking at the pulley/belt arrangement, the only way you could do this would be to remove the compressor and replace it with another idler pulley. Eliminating the compressor, not using an extra idler and using a shorter belt would cause the water pump to run backwards (won't work that way). If the clutch on the compressor is OK why not disconnect compressor from the harness and just let the clutch freewheel without engaging?

Alternator Belt


TAKE A ROPE AND RUN IT AS IF IT WERE A BELT ALONG THE ALTERNATOR AND CRANKSHAFT. MEASURE THE LENGTH OF ROPE THEN GO TO PARTS STORE TO BUY A SMALLER BELT. THE IDEA IS TO BYPASS THE AC BEING A 94 IM SURE IT HASN'T WORKED IN QUITE SOME TIME, I'VE BEEN A MECHANIC FOR 8 YEARS AND WE BYPASS THESE ALL THE TIME, THE TENSIONER ON THAT CAR I BELIEVE IS ON THE ALTERNATOR, HONDA MADE THE AC OPTIONAL.. BELTS ARE USUALLY NAMED AFTER THERE SIZE (IE 4060934 IS 93.4 INCHES LONG) IF NEED BE REMOVE THE AC COMPRESSOR.
