How to Replace the Alternator in a Chevy Camaro. The Chevy Camaro uses an alternator to run electrical devices in your vehicle while the engine is running. A voltage regulator maintains a constant voltage level and is frequently integrated into the alternator assembly. If your battery continually runs down or your headlights become dimmer while the engine is running, you may need to replace the alternator.

Determine which alternator your Chevy Camaro will need. You'll want to be sure the new alternator is compatible with your Camaro's engine. Models made from 1967 to 1969 were available in a variety of engine sizes including 3.8 L, 4.0 L, 4.9 L, 5.4 L, 5.7 L, 6.5 L, 6.6 L and 7.0 L.

Look at engine sizes for additional Camaro models. The second generation Camaro covers the years 1970 to 1981 and was offered with 3.8 L, 4.1 L, 5.7 L, 6.5 L, 6.6 L and 7.4 L engines. The third generation was made from 1982 to 1992 and came with 2.5 L, 2.8 L, 3.1 L, 5.0 L and 5.7 L engines. Models made from 1993 to 2002 had the option of a 3.3 L, 3.8 L or 5.7 L engine.

Position your vehicle over a hoist and raise it. Disconnect both battery cables with a socket wrench and remove the accessory drive belt.

Slide down the boot on the alternator to access the positive terminal stud and remove the nut on the stud with a socket wrench. You will now be able to remove the cable.

Remove the mounting bolts for the rear bracket of the alternator with a socket wrench and disconnect the cooler lines for the transmission oil. Unscrew the mounting bolts of the front of the alternator and take off the oil cooler clip. Remove the alternator from the vehicle.

Install the new alternator assembly by reversing the removal process. Tighten the mounting bolts on the front of the alternator with a torque wrench to 37 foot pounds and torque the mounting bolt on the rear bracket to 18 foot pounds. Torque the nut on the alternator stud to 16 foot pounds.
