Q: How to replace an alternator in a Chevrolet C1500 and K1500?
A: Remove the cable from the negative battery terminal. Caution: On models equipped with Theftlock audio system make sure to turn off the lockout feature before you perform any procedure that requires disconnecting of a battery. Take out the wires from the alternator. Remove an alternator drivebelt. Unscrew mounting bolts and separate an alternator from the engine there is one more particular case to consider though at this point If you replace alternator, take old one to shop with you when purchasing new ones Be sure that your new/rebuilt unit looks identical to your older one First look at terminals- they should have same number, size, and location as on old alternator Look at identification numbers stamped into housing or printed on tag attached thereto Finally, ensure that both of these numbers are similar for two models Many new/rebuilt units don't have a pulley in them so you may need to switch it from old unit to new/rebuilt one Ask about policy regarding pulleys while buying an alternator because some shops can do it for free Reverse earlier procedures for installation Check tension of drivebelt after you put back everything Test charging voltage using check light or voltmeter.
