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.

The Cadillac CTS specifically pertaining to the Drive Belt is extremely important since it interconnects the engine to essential parts like the alternator, A/C compressor among other things. Usually a serpentine belt is used, encircles these elements and connects them to the crankshaft pulley. This design enables power to be transmitted effectively with most Drive Belts expected to last for about 100000 miles albeit to some they may wear off early. For the last few years Cadillac CTS has used various types of Drive Belts, which are V-belts and multi-groove belts both having their own benefits. V-belts improve the belt/accurate traction and long working life while multi-groove belts offer flexibility and high effectiveness for complicated power transmitting processes. Drive Belt type has implications on performance and frequent replacement and Cadillac CTS owners have to keep an eye on its condition to avoid major problems with the engine and parts.
