The pully on the compressor is bad can i just leave off the compressor and bypass it with a different size belt

They sell a by - pass pully .take A/C compressor off all together , uses same belt that's on .

How did they disable the ac if they didn't bypass the pully that is why the belt shredded. The compressor is probably locked up thefore unless the pully is bypassed the belts will continue to shred

If you are going to bypass it then you need a different sized belt or a different pulley and believe me that's guess work till you find the right one

use a smaller belt use a pice of cord to measure

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.

• Under the hood in the relay panel will be a relay for the compressor. When you locate the relay box look on the underside of the lid for the legend (layout) of the relays. Pulling that relay will stop the compressor from turning on.
• You can also just unhook the connector on the compressor and secure it to stop the compressor from turning on.
• If you need the compressor clutch to not turn at all, like if the bearings are bad, then you need to buy a smaller belt to bypass the compressor all together.

• Hope this helps and thank you for using FixYa.

Why would you want to do that?

If the compressor is bad or frozen, just disconnect the wiring or pull the A/C fuse and leave it on the pully.

well it depends on the year and size of motor, on most cars you cant bypass some you can, if you go to parts store and have them look up that car without ac and see if they have a listing, what i do is theres a pully and bracket you buy, you remove the a/c compressor and it bolts up there and it uses the same belt, it costs about $40.00 for the part and most part stores carry or can order for you.

You will need what is called an idle pully and be fitted instead of the compressor the same belt will fit. This is the correct way. An alternative way is to take the bely off the compressor pully and leave it on the other pully's pull it hand tignt holding the excess of the belt in your hand. Now check the belt won't rub on the engine or component's. If the belt has fully cleared all then Release the tensioner all the way and measure the length of belt needed to go around all pully's except the compressor. Take the measurement and the old belt to an autofactor's the old belt is important to have because the dimentions of the belt depth and width are also important. They will be able to check for a belt to suit your need's. Belt dosent need to be the exact length of your measurement 1 to 3 inches longer should be adjustable. cheers

yes, there could be an "a/c delte" pulley out there that would go where the compressor was. double check that you are routing the belt right. all other pullies are the same. maybe your diagram is wrong or you are misinterpreting. (it happens to everyone) if you still can't get it, you can wrap a peice of string around all the pullies, measure the string, and ask for that size belt.
