• Q: How to replace the A/C Clutch assembly on 2007 Chevrolet Impala?

  A: One needs to obtain several tools before replacing the compressor clutch assembly: a compressor clutch holding tool (J 37872) together with snap ring pliers (J 6083). J 37872 compressor clutch holding tool and j 6083 snap ring pliers are required. Start by taking out the compressor and three adjustable dowels from the compressor clutch holding tool (J 37872), then install three 5/16 x 1 inch bolts. Discard the compressor clutch plate bolt and position the j 37872 compressor clutch holding tool to secure the compressor clutch plate during removal procedures. The compressor pulley snap ring can be removed using snap ring pliers (J 6083) before removing the pulley itself. The technician should use snap ring pliers (J 6083) to remove both the compressor clutch coil snap ring and coil itself. Through the installation process first use an m6x1.0 tap to clean clutch plate bolt threads before applying compressed air to clear remaining debris. Use snap ring pliers (J 6083) to install the compressor clutch coil followed by installation of the compressor clutch coil snap ring using the same tool. To begin installation use the snap ring pliers (J 6083) for attaching the compressor pulley and its snap ring. Place a 0.4 mm (0.016 in) air gap shim inside the clutch drive plate using small amounts of oil before putting on the compressor clutch plate. Normal compressor pulley rotation should not trigger drive plate contacts with the pulley. Utilize the measurement tools to check pulley-drive plate air gap distances and readjust the shims to yield between 0.3 to 0.6 mm (0.012 to 0.024 in) air gap distance. Tighten the new drive plate bolt to 12 n.m (106 lb in) after first making sure the bolt shows colored adhesive on at least 5 threads. Perform this operation while using the compressor clutch holding tool (J 37872) to stop the clutch plate from rotation. After compressor reinstallation complete a leak test on all fittings by using the leak test tool (J 39400-A).
