nhang Posted October 6, 2010 Report Share Posted October 6, 2010 I have a 02 Caddi. The AC belt start making noise (flapping). One day the tension broke and ever since every new belt that installed break in a few days. BTW, the flapping noise seems to cause the belt to break. Anyone experience this problem? HELP!!

BodybyFisher Posted October 6, 2010 Report Share Posted October 6, 2010 Check your idler pulley wheel and tensioner pulley for looseness, if they are bad, your belt will be thrown off and damaged Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
KHE Posted October 6, 2010 Report Share Posted October 6, 2010 The Escalade uses the same belt drive as the Chevy trucks - there is a separate belt and tensioner for the A/C compressor. The Denso compressors from 2000-2003 are notorious for locking up when they are about to self destruct. When they lock up, they snap the belt. You need to replace the compressor, accumulator, and orifice tube. If the orifice tube does not have any shavings, you should be good. If it has shavings, the condenser and rear expansion valve need to be replaced and the lines, front and rear evaporators will need to be flushed prior to replacing the components. All seals/o-rings for the connections that are opened will need to be replaced as well.
