alternator belt keeps falling
 

Alternator belt also runs to the AC compressor. That is where the problem is. The bolt that holds the compressor in place keeps falling out. I dont know why, but once it does there is no more tension in the belt and off it comes. I dont even want to bother with the compressor anymore. I just want to know if anyone knows of a belt that I can run from the engine straight to the alternator. By the way, its an '87 944na. Thanks.
