How do you replace an alternator 1990 F-150 4.9?

here is the basic steps, I don't consider myself a mechanic but found this job to be pretty easy. 1. Disconnect battery 2. Remove belt from alternator (much easier with belt tensioner tool that most part stores will lend) 3. Remove 2 bolts holding on alternator 4. Wiggle alternator out of place 5. place new alternator back where old one was 6. perform other steps in reverse order. (it helps to start by putting back the long bolt 1st then the short one.) When changing out the alternator it may be a good time to change out your serpentine belt if it needs to be done.
