How to replace the air conditioning compressor and power steering pump drive belt on Cadillac CTS?

The first task in changing the air conditioning compressor together with the power steering pump belt starts with removing the generator and water pump Drive Belt. After you should detach the air cleaner outlet duct from the system. The Drive Belt tensioner requires clockwise rotation to let go of tension so the Drive Belt can be successfully extracted from the power steering pulley while the tensioner is released gradually. The required step is to extract the Drive Belt from the accessory drive pulleys. The new Drive Belt installation process requires first positioning it on the Crankshaft Pulley and idler pulley together with the A/C Compressor before rotating the tensioner clockwise to put the belt around the power steering pulley while releasing the tensioner slowly. The Drive Belt needs to be correctly positioned inside the accessory drive pulley grooves. After finishing installation complete the procedure by putting back the air cleaner outlet duct together with the generator and water pump Drive Belt.
