Because a/c has become pretty much "standard" on most vehicles instead of an option, belt routing without the compressor is generally a nightmare if not impossible. BUT there is a company (Pretty sure its Dorman) that makes a bracket with an idler pulley that is configured to fit right where the ac compressor was...Thet way, routing remains exactly the same and you can even use the same belt #.

SOURCE: By-passing the a/c compressor with a shorter belt

The best way to do this is first ask the parts house to see if this car came with out air and get a belt that way. I dont think that year had the option of not havnig A/C. The other way is take a piece of rope and put it around the pullys just like you are puttin on the belt but by pass the A/C you might have to make a few trips or get a few different size belts but its the only way

SOURCE: I need to know how to route the serpentine belt to

you will have to buy a new tensioner that pushes in the opposite direction as the one that is on there now, and there should be a diagram right under the hood on a yellow sticker that show a solid line for the routing with the airconditioner and a broken line without. I had to do the same thing last year!

3.0L And 4.0L Engines

  1. Disconnect the negative battery cable.
  2. With the vehicle in neutral, position it on a hoist.
  3. Remove the splash shield.
  4. Rotate the accessory drive belt tensioner clockwise for 2001-2004 models and counterclockwise for 2005-2006 models. Remove the belt.
  5. To install, reverse the removal procedure.

Serpentine Belt
All Navajo and B Series Pick-up engines utilize one wide-ribbed V-belt to drive the engine accessories such as the water pump, alternator, air conditioner compressor, air pump, etc. Because this belt uses a spring loaded tensioner for adjustment, belt replacement tends to be somewhat easier than on engines where accessories are pivoted and bolted in place for tension adjustment, such as the MPV. Basically, all belt replacement involves is to pivot the tensioner to loosen the belt, then slide the belt off of the pulleys. The two most important points are to pay CLOSE attention to the proper belt routing (since serpentine belts tend to be "snaked" all different ways through the pulleys) and to make sure the V-ribs are properly seated in all the pulleys.

Although belt routing diagrams have been included in this section, the first places you should check for proper belt routing are the labels in your engine compartment. These should include a belt routing diagram which may reflect changes made during a production run.
  1. Disconnect the negative battery cable for safety. This will help assure that no one mistakenly cranks the engine over with your hands between the pulleys.
Take a good look at the installed belt and make a note of the routing. Before removing the belt, make sure the routing matches that of the belt routing diagrams. If for some reason a diagram does not match (you may not have the original engine or it may have been modified,) carefully note the changes on a piece of paper.
  1. For tensioners equipped with a 1 / 2 inch square hole, insert the drive end of a large breaker bar into the hole. Use the breaker bar to pivot the tensioner away from the drive belt. For tensioners not equipped with this hole, use the proper-sized socket and breaker bar (or a large handled wrench) on the tensioner idler pulley center bolt to pivot the tensioner away from the belt. This will loosen the belt sufficiently that it can be pulled off of one or more of the pulleys. It is usually easiest to carefully pull the belt out from underneath the tensioner pulley itself.

  1. Once the belt is off one of the pulleys, gently pivot the tensioner back into position. DO NOT allow the tensioner to snap back, as this could damage the tensioners internal parts.
  2. Now finish removing the belt from the other pulleys and remove it from the engine.
To install:
  1. While referring to the proper routing diagram (which you identified earlier), begin to route the belt over the pulleys, leaving whichever pulley you first released it from for last.
  2. Once the belt is mostly in place, carefully pivot the tensioner and position the belt over the final pulley. As you begin to allow the tensioner back into contact with the belt, run your hand around the pulleys and make sure the belt is properly seated in the ribs. If not, release the tension and seat the belt.
  3. Once the belt is installed, take another look at all the pulleys to double check your installation.
  4. Connect the negative battery cable, then start and run the engine to check belt operation.
  5. Once the engine has reached normal operating temperature, turn the ignition OFF and check that the belt tensioner arrow is within the proper adjustment range.

Hope helps (remember rated and comment this).

I don't know of any way to by-pass the A/C compressor or any component in a serpentine belt system; but, you can unplug the compressor clutch (at the nose of the compressor, behind the pulley), then the compressor will not turn and the pulley just acts as an idler.

I am hoping to by pass the ac compressor on my 2000 sebring convertable until I can get the money to replace the compressor

if the clutch wheel turns freely, then you can leave it as it is, it won't try to engage unless you put the selector to ac, if thats what you needed to know, other wise,, you would need to check with either the dealer or parts store to get a belt that will fit that make , model, motor size, and year , without ac.. be sure that the routing can be accomplished so that all the belt driven parts travel in the correct direction,

I need a serpentine belt routing diagram to eliminate A/C compressor that is bad. The vehicle is a 2003 Ford Taurus with DOHC V6

A company named MOTORMITE makes a pulley assembly (by-pass kit) just for this purpose. You simply remove the compressor and the pulley bolts in where the compressor was. This way, you can use the same belt and belt routing as the original. (see picture)

The part number for this by-pass kit is 34166
It is available at AutoZone and other parts retailers for around $40.

Need to bypass ac compressor

Hi yotaguy,
You will need to buy a By-Pass pulley, due to the placement of the other pulleys you will not be able to eliminate the ac and still run the correct routing of the belt.
I will research the price of the pulley and post it here.
Please rate this solution, the only compensation I receive for my time is the knowing I have helped and the rating I receive here on Fixya.

1993 buick century ac by pass

If the comprtessor itself is bad, you can unplug the activation wire located up fron of the unit, this will allow the clutch bearing to turn separate of the compressor. If the clutch bearing is the cause you will have a problem, these belt systems are so crazy that it would be almost impossible to select a belt to do what you want.
