Yes it is called A/C Compressor Bypass Pulley. It bolts directly to the AC Compressor bracket.

Bypass serpentine bell 2000 Ford Expedition 5.4 l


I am assuming you want a belt that provides a bypass for the A/C pulley. Unfortunately, newer vehicles don't give you the option of getting A/C anymore like in the old days. Used to be you went to the auto parts store and just asked for one w/o A/C and got it. Some later models did offer no A/C, but put idler pulleys in place to keep the same belt length. If there is no second option for a belt, you will need to get real creative if you want to bypass anything. It is important that you ensure that any bypass belt you install doesn't cause a change in the rotational direction of any of the critical pulleys (water pump, power steering, alternator). Some folks just buy a junk A/C compressor from a salvage yard that has a good pulley bearing, mount it but don't power it up or charge it.

Bypass ac compressor with shorter serpentine belt 2001-02 Mercury Sable LS


Because in most cases the routing will not work without the pulley for the compressor being in use. That's why some engines have a dummy pulley available to use in place of the compressor.
Not using the compressor pulley can cause the belt to drive a pulley the wrong direction, or not have the grooved side of the belt on a pulley.

At Auto Zone, ask for part number 34223. It is a bypass pulley that you can replace the a/c compressor with so you can use the original belt without issue.

My compressor is bad on my 2000 pontiac sunfire 2.4, i am wanting to bypass the belt with a new (smaller belt) can u please tell me what size i will need


Hi,

Improve the Fixya.com experience for everyone by voting!

What you are looking for is called an 'air conditioner compressor bypass pulley'. Most chain auto parts stores have them in stock.

All you do is install the bypass pulley and use a shorter belt.

The only downside is the cost of $25-$40. That's about one-third the cost of a remanufactured unit and the labor is compatible.

All the best

My air conditoning compressor is making a grinding noise and it hasn't worked for years. Is there a way to change the pully on the water pump and just put a new serpantine belt on to bypass the compressor?


What engine?

They make a pulley adapter to install in the place of the a/c compressor for vehicles that the a/c con not be bypassed. You local auto parts store will have them. Sometimes they cause more problems than they solve.

The best solution is to replace the compressor with a new or even a used compressor.

A good possibilty is the compressor will lock up and either burn the serpentine belt off or a no start condition because it will not allow the engine to rotae.There is a less expensive alternative many of these trucks have an ac bypass kit available from auto zone or advanced that replaces the compressor with a bracket and a pulley in place of the compressor.

On a 2001 saab 93 turbo can can you bypass the ac compressor or is there a bypass pulley


You can bypass both the AC compressor and the middle serpentine idler pulley with a 6PK1790. The middle pulley is bypassed by running the belt straight line from the upper rear serpentine idler straight to the power steering pulley, then over the water pump (the smooth pulley powered by the back side of the belt) and down to the engine drive pulley (harmonic balancer), bypassing the AC compressor) This works fine. On 9.5 models, the same basic idea, but a slightly different sized belt.

A/c mount broke off the actual compressor, no way to attach to engine mount, has a serpentine belt , can i get a belt shorter that will bypass the ac.


You can buy an A/C bypass pulley from an O'reilly auto or anyone that supplies Dorman parts. the pulleys are cheap and allow you to mount things and use the stock serp belt. You will have no AC ,though. The kit is designed with the intent of eliminaing the compressor, which is very expensive to replace.
