Next, remove the drivebelt and the heater hose pipe retaining bolts from the alternator support bracket.

Disconnect the cable from the negative battery terminal. Remove the drivebelt. On six-cylinder models, unbolt the air conditioning line mounting bracket located at the engine lift hook. Remove the right engine lift hook and the alternator mounting bolts, then remove the alternator from the engine. Disconnect the electrical connectors from the alternator. On V8 models, disconnect the output wire and the electrical connector from the alternator. Remove the mounting bolts and remove the alternator from the engine. 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 Id 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 to the specific torque. Install the drivebelt. Check the charging voltage to verify proper operation of the alternator.
