hi im new to the site, and i have a problem. My 2002 GT is getting old in the mileage department and the engine has began making a hissing/knocking sound...though i dont think its the engine but the compressor for the air conditioning....im not even sure if its called that but the culprit is below the front pulleys on the bottom left hand side of the front of the engine.

has anyone else experienced this..is it common? and more importantly does anyone know what i can do to fix it?

How many miles are on the car?

Take the belt off and see if the idler pullies spin freely.

A likely culprit is the idler pulley.
