Re: Will A.C. compressor pulley seize shear the belt? Posted by Ari [Email] ![]() ![]() In Reply to: Will A.C. compressor pulley seize shear the belt?, Ian Drury, Sun, 8 Jul 2001 13:59:56 Members do not see ads below this line. - Help Keep This Site Online - Signup |
When the compressor siezes, it stops turning, but the belt keeps turning. The AC system doesn't know there's a problem, so it engages the clutch. This causes the clutch to burn up - quite often with some pretty impressive smoke. This cooks the bearing in the AC clutch and compressor, quite often fusing everything together.
Reading down, if you have a 91, that has only one belt. Bad news - you need a AC compressor, or at least an AC clutch pulley, to run the car. If you try and run the engine, something will break. If the AC clutch is stuck, it won't move but the belt will, and the belt will break/melt/fail in a minute or two.
A cheap solution is to pull the old AC clutch, and just replace that. Then remove the wires to it. (And pull the fuse, but disconnect the wires just in case). That will give you in effect an idler pulley, and the car will be driveable, just without AC.
