AC Belt


nhang

Recommended Posts

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!!

Check your idler pulley wheel and tensioner pulley for looseness, if they are bad, your belt will be thrown off and damaged

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.
