For V8 engines, disconnect the wiring from the alternator and move the wiring harnesses out of the way. If you are replacing the alternator, take the old one with you when purchasing a replacement unit. Make sure the new/rebuilt unit looks identical to the old alternator. Look at the terminals-they should be the same in number, size and location as the terminals on the old alternator. Finally, look at the identification numbers-they will be stamped into the housing. Make sure the numbers are the same on both alternators. Many new/rebuilt alternators do not have a pulley installed, so you may have to switch the pulley from the old unit to the new/rebuilt one. When buying an alternator, find out the shop's policy regarding pulleys; some shops will perform this service free of charge. Installation is the reverse of removal. Tighten the mounting bolts.
