So the AC compressor siezed today and took out the serpentine belt on my 93 Taurus with the 3.8 and I'm wondering if its possible to bypass it with a shorter belt or if I have to either buy a new compressor or an idler pulley to fix it. Any help would be greatly appreciated as its my only car and is now not driveable.

Check on the underside of the hood or near the front of the engine bay for a belt diagram. They will usually show if you can just use a smaller belt to delete the AC. I searched napa and autozone and they seem to only show one belt size. Napa does have idler pulleys to take the place of the ac unit for around $30.

Just because the compressor seized doesn't mean you have to swap belts. If the compressor pulley seized, then you will have to bypass it. The pulley is only connected to the compressor when the clutch is engaged, so if the pulley still spins free, just unplug the compressor.

Yeah its the pulley thats siezed and took out the belt, the pulley does not spin free even with the compressor isn't engaged.

hmm...that kinda sucks. I honestly don't know of a belt that can work to bypass it, but I know the aftermarket has A/C bypass kits available...

Hello,

I have the AC delete pulley I bought for my 95 Taurus with a 3.8. I ended up repairing the AC and never did use the pulley. It is brand new I would sell it for $20.00 plus shipping. I paid about $40.00 for it.

Email me at brn2fsh@bresnan.net if interested.

The sticker under the hood shows a dotted line as if you can get a smaller belt to bypass the AC compressor. I don't know if these belts are actually available though. I think the best bet is to go to the parts department at a Ford dealership and find out for sure.

I got it all sorted out, thanks guys! The pulley now spins without the compressor engaged, I went out the next day and tried to spin it after it cooled down and it does so I just threw a belt on it and have been driving it for 2 days so far with no problems.

On the 3.8L (Essex) engine (at least in my 1994 Taurus GL), I'm not sure how one would install a shorter belt to bypass the compressor pulley, since the belt would rub mightily against the hose that runs from the water pump to the bottom of the radiator, and I can't see a practical way to re-route that hose. So it seems on the 3.8L anyway, if you want to do without a compressor that has a seized pulley or clutch, you'll have to either fix the pulley/clutch (and just let it freewheel if that doesn't get the AC working), or remove the compressor and install a bypass pulley.
