• Q: How to replace the A/C Clutch assembly on 2008 Buick LaCrosse?

  A: Before replacing the compressor clutch assembly begin with accessory Drive Belt removal from the A/C Compressor according to the Drive Belt replacement procedures designed for engine types 3.8l (L26), 3.6l (LY7), or 5.3l (LS4). 3.8l (L26), 3.6l (LY7), or 5.3l (LS4). Start by removing the compressor and lower air deflector while removing three adjustable dowels from the j 37872 compressor clutch holding tool and installing three 5/16x1 inch bolts in their place. Remove the compressor clutch plate bolt after discarding it and proceed by attaching the j 37872 to firmly hold the compressor clutch plate during removal. The j 6083 snap ring pliers permits the removal of the compressor pulley snap ring as well as the compressor pulley and the compressor clutch coil snap ring followed by the compressor clutch coil. To prepare for installation work on the compressor clutch coil follow these steps: first use an m6x1.0 tap to clean the clutch plate bolt threads then blow away debris with compressed air before using the j 6083 to install both the clutch coil and its snap ring. Plug the compressor pulley and its snap ring into place before applying oil onto the clutch drive plate's 0.4 mm (0.016 in) air gap shim which then must be placed inside before installing the compressor clutch plate. As you rotate the drive plate verify that it doesn't scrape against the pulley then use the air gap measurement between pulley and drive plate to adjust the shims for a 0.3-0.6 mm (0.012-0.024 in) gap. Tighten the new clutch drive plate bolt to 12 n.m (106 lb in) while utilizing the j 37872 to hold the compressor clutch plate. The bolt requires colored adhesive to cover at least 5 threads. Expose the lower air deflector following installation of the accessory Drive Belt and specific engine type compressor reinstallation. Finish the work by conducting a leak test on fittings through the j 39400-a halogen leak detector.
