Disconnect the cable from the negative battery terminal. Remove the drivebelt. Push back the protective cover from the alternator's battery terminal, remove the nut and disconnect the battery cable from the alternator. Disconnect the electrical connector from the alternator. Remove the alternator mounting fasteners and remove the alternator. If you're replacing the alternator, take the old one with you when purchasing the replacement unit. Make sure that the new/rebuilt unit looks identical to the old alternator. Look at the electrical terminals on the backside of the alternator. 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 or printed on a tag attached to the housing. Make sure that the ID numbers are the same on both alternators. Many new/rebuilt alternators DO NOT have a pulley installed, so you might have to swap the pulley from the old unit to the new/rebuilt one. When buying an alternator, find out the store's policy regarding pulley swaps. Some stores perform this service free of charge. If your local auto parts store doesn't offer this service, you'll have to purchase a puller for removing the pulley and do it yourself. Installation is the reverse of removal. Tighten the alternator mounting bolts securely. Reconnect the cable to the negative terminal of the battery. Check the charging voltage to verify that the alternator is operating correctly.

This alternator is 110 amps
