To change the alternator on a 1987 to 1990 Chevy Celebrity V6:

First disconnect the ground cable from the battery.

Use a 3/8" breaker bar or ratchet in the square on the end of the belt tensioner to release the tension and take the serpentine belt off of the alternator drive pulley. There should be a routing chart on the belt guard between the water pump and the power steering pump.

Remove the three bolts that attach the alternator to the mounting bracket.

Pull the alternator up and disconnect the plug and use a wrench to disconnect the battery wire.

Reverse the process to install the new alternator.
