How to Remove the A/C Compressor Clutch in a Chevy Tahoeby Kyle Sanstrom
The A/C compressor clutch in a Chevrolet Tahoe is an electromagnetically-actuated unit. It is designed to engage the A/C compressor shaft when it receives the proper amount of current from the powertrain control module. As it wears, it loses its ability to properly engage the A/C compressor unit without slipping. Replacement compressor clutches are available from auto parts stores and automotive dealers. The A/C compressor clutch must be removed with a special puller designed to uninstall it without damaging the A/C compressor.
Turn off the engine and place the SUV in park. Apply the parking brake and disconnect the negative battery terminal using a battery terminal wrench.
Compress the serpentine belt tensioner with the serpentine belt removal tool and slide the belt off of the A/C compressor pulley.
Insert the male threaded end of the compressor clutch removal tool into the female threaded end of the clutch. Thread the removal tool into the compressor clutch until it becomes too difficult to turn by hand. Tighten it with a standard open-end wrench until it is completely seated.
Tighten the center screw on the clutch removal tool with a 3/8-inch ratchet until the clutch begins to pull away from the A/C compressor.
Tighten the center screw with the 3/8-inch ratchet until the A/C compressor clutch completely separates from the compressor unit.
