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

  A: Before the compressor clutch assembly replacement requires the compressor removal during which the three adjustable dowels from the j 37872 universal spanner wrench (J 37872) must be replaced with three 5/16 x 1 inch bolts. While holding the compressor clutch plate immobile with j 37872 discard the compressor clutch plate bolt before removing the clutch plate. The process starts with using j 6083 snap ring pliers (J 6083) to remove a compressor pulley snap ring before finally taking out the pulley. Use j 6083 snap ring pliers (J 6083) to extract the snap ring from the compressor clutch coil. First clean the clutch plate bolt threads using an m6x1.0 tap before blowing out debris with compressed air prior to compressor clutch coil installation. The j 6083 will help you replace the clutch coil snap ring then you can install the compressor pulley and its snap ring with the j 6083. Put a drop of oil onto a 0.4 mm (0.016 in) air gap shim then place it between the clutch drive plate and clutch plate while ensuring the plate remains free of contact with the pulley. Use shims to create an air gap measurement of 0.3-0.6 mm (0.012-0.024 in) between the pulley and drive plate. The j 37872 should hold the compressor clutch plate while you tighten the new clutch drive plate bolt with colored adhesive on at least 5 threads to 12 n.m (9 lb ft). The compressor installation requires a leak test on fittings by using the j 39400-a before finishing the work.
