I have done a few alternators and one on a cavalier before. The parts are about 100 dollars and the beer is about ten...the rest is pretty easy. The hardest part is holding your beer! Just use your 1/2" breaker bar(might have been 3/8") and release the belt...after that you are talking 3-4 bolts. Reverse to get it back on. Shouldn't take more then 1/2 hr 45 minutes.
