Anyone know if you can route the serpentine belt bypassing the ac compressor (It locked on me, the compressor), and if so anyone have a diagram or which way to route it?...And what size would be needed? Its a 1995 Crown Victoria (I figured if anyone knew, this would be the place)

These cars have always been sold with A/C...so to bypass the compressor you would need to find a way to shorten the belt or get a shorter belt.

here is my idea:


THe blue line is the factory belt routing, the green the revised route.


In this setup, the tensioner will still tension the belt, routing/direction on all accs. is correct.

However, this setup doesn't give a lot of belt wrap on the alt, nor can the tensioner work to its full extent (but it will work some though) so don't run this setup long IMO. Also, you will need to experiment with belt length. Grab your self one of those string-like 'tape' measures and route it on the new belt setup, while someone holds back the tensioner some. This will give you a close size as to what you will need so it won't be too loose and the tensioner can do some of its job.
Again, I do not recommend this setup for extended time, just till you get it fixed...

I think that you have to go the other side of the tensioner but then again I am just sitting in the chair thinking about it.

If the pulley doesn't turn, the compressor isn't locked. The pulley is. Replace it. $100ish for a complete new clutch kit at NAPA.

My first drawing was like that, but then I thought when i changed my belt the tensioner pulled upwards, so I re-did it with it on that side. Otherwise the tensioner would jsut go to its fully extended postion and be useless/bypassed.

Then again, I honestly cannot remember which the tensioner pulls
Ben, you wouldn't happen to remember would you?

On topic to bypass air-con aggregate:

Proposed (above pictorials) serpentine belt routing to bypass air-con unit is as entertaining as Arnold Hollywood flick. Technically speaking, it has serious engineering flows:

1. Serpentine belts are vehicle specific and are not available in any size one would need. Owner would face enormous waste of time to find one.

2. To thread the belt into the path is next "Mission Impossible". Old fashion way using the slotted alternator mounting holes and breaker bar is out of picture, it (the alternator) is firmly bolted to the bracket.

3. Tension arm is applying force vertically (up), therefore I don't see how it would help to keep the belt from squealing.


Summary:
If the owner is able to overcome tasks #1. and #2 successfully he will have to crank up his 200 watts stereo to mask terrible squealing belt noise.
Bypassing is not very good solution, changing that $100 pulley is the only way to go.

Actually, you CAN buy belts in the size you need. Any decent parts store, like a Napa, can get you the one you'll need.

Not sure why you think the belt would be impossible to install. The belt is slightly longer than the actual needed belt length, the tensioner makes up the rest.

THe tensioner WOULD apply force to the belt in those diagrams, not as much as desired, but it would.

Agreed, but if he cannot get one right now, and needs the car, this method will work short-term. We have doen basically the same exact thing on a truck of ours that had the a/c clutch seize, and thus shredded the belt and then the pulley disappeared. Doing the same thing as above, we were able to finish the work day and drive the truck home.

Again, I only recommend this setup for extremely short term use, alt and tensioner belt wrap are very low.

Its been awhile since I looked at this topic...I just noticed the comment that if the pully is frozen solid, its not the compressor?

Yesterday, my AC comp just went right at lunch and i'm kinda stuck at work and home is 80 miles away. The pulley would still spin but something with the clutch is locked and it's heated up, smelled like burnt brake pads, and flame up some of the material on the front. Talk about almost hyper ventilating trying to blow out the flame. Anyways after looking here for belt routing without AC, then taking a chance and driving it to Autozone, found out the without AC belt option in the AZ computer was the same for with AC. 2 hours later and many belt try outs, the one I have that worked is the Duralast belt #795K6. It squeaks until warm up. But the next size down is #790K6 which may fit perfect but they were out. FYI 99 CV P71 to run without A/C try these belt sizes from Autozone.#795K6 or 790K6

Thank you for your idea. Just tried it,and tested it for 190 miles on my 99 CV P71. Just had to find the belt for it. Autozone belt # 795K6 or 790K6.

Just a note; The 790K6 is the better fit.
