If it doesn't make any noise when AC is off, and your o.k. with that, just unplug the connector going to the compressor & it won't engage the clutch anymore.

    By the looks of the belt routing, you may be able to by-pass the AC compressor without it rubbing anywhere. The big question is, does the part store have a listing for your vehicle without AC. Here's what I would do if not. With belt on obviously, I would mark the belt & pulleys at the power steering pulley & crankshaft pulley, in a location that I could get a straight across measurement, and record that measurement. Then I'd remove the belt & measure the distance of my marks on the belt, and subtract the distance I measured straight across. Then subtract the difference, and go shopping for a belt that much shorter than the original. The autoparts store has belt measurement gauges if necessary but usually the belt length is marked on the belt or package. Now install the new shorter belt, without going around AC pulley. Make sense?

Not very easy to change- you have to evac the a/c system- then all your work is underneath. they may sell a bypass pully to put in place of the compressor- but i dont beleive you can just put a shorter belt on. hope this helps and good luck

    02 and 04 shouldnt be much difference- you shouldn't have to modify anything to take the compressor out- they really are not easy to get out tho. if you dont want to put another compressor in you need to find a pully kit to put in place. napa usually has them

What size serpentine belt do i use to bypass the ac in a 2000 ford windstar

Hi Jenni,

If you have a bad or locked-up A/C compressor, you do not have to change the belt at all unless the clutch bearing is bad. Otherwise, the belt will simply ride on the clutch pulley without any problems. All you have to do is to disconnect the A/C clutch wire connector to keep the clutch from engaging and destroying your belt.

On the other hand, if the A/C clutch bearing is the reason you are wanting to "bypass" the A/C, it would be best to just replace the clutch bearing. The bearing is available by itself. This will work to solve your problem even if your compressor is locked-up (see above).

The SANTECH part number for your compressor clutch bearing is MT2024. You should be able to grab on to one of these for arond $15 US (lots cheaper than a belt)

I don't recommend messing with trying to find a different belt to try to "bypass) the A/C compressor, because you will be opening a whole can of worms that will be aggravating and EXPENSIVE to deal with. The method described above will ensure that your belt will fit correcly and will have the correct amount of tension to prevent slipping, squealing, or damage to other bearings or pullies.

I think my a/c clutch pulley is bad on my 05 trail blazer and broke the belt can i bypass the compressor with a shorter belt

Yes you can, many TB's owners have done this. I'm in need to do this also. Does it make a horrible sound when the A/C is turned on? Probably the bearings which are welded in the compressor. Cheapest way to fix this, is to use a dremel tool to cut the welds and replace the bearings. But you can also, get a different compressor.

It makes a rattling noise when i turn on and it keeps going on when im driving. People toll me it could be the A/C Compressor.How can i fix it myself?

Actually, any belt driven accessory could be the cause of the rattling noise, A/C compressor being one of them.

Maybe try to remove the belt, and then spin and check for side to side play of each of the pulleys.

The bearings in one of the turnable pulleys may be going bad.

Rattle noise coming from belt

this could be a bad pulley or alternator, you will need to remove the belt and spin the pulleys by hand to see which one is making noise, it could also be the ac compressor pulley, start there.

The AC compressor bearing making ugly and loud noise

You must replace the Air Conditioning Compressor or replace it with a bypass pulley. If you remove the belt, you will lose power steering, cooling ability and the ability to charge your battery with your alternator. Remove the belt, crank the heat and drive it to where you'll be repairing it. You only get one shot!

Sounds like a bearing going bad where do i look first

a rod bearing makes noise when you are just barely pulling .. it likely will quiet down as you accelerate and decellerate .. you can rev the engine up a bit then let up on the gas just enough to keep that rpm ..a rod bearing will rattle a lot then ... if a thud like noise happens when you are accelerating . then it could be a main bearing .. if the noise is there all the time and sounds like a rattle then its more likely a valve problem .. old oil can cause the lifters to stick and rattle continuously .. if the noise you hear is a squeal then you could have a bad bearing in the idler pully (for fan belt) or alternator .. if thats the case you can put a drop of oil on the bearings one at a time until the squeal goes away .. that will identify which part is going bad .. there are other less likely bearings that can go bad .. like the cam, distributer, air compressor and water pump .. each have their own type noise ..
