How do you release the tension on the AC compressor belt on a 1998 4 Toyota 4 Runner?

Answer 1

4 cyl and 6 cyl are different. The 4 cyl has an idler pulley on the under side of the engine and you must remove the skid plate to gain access. Once you gain access,loosen the nut on the idler gear a turn to a turn and a half is all. Then loosen the nut that tightens the pulley until you can remove the belt. On the 6 cyl you need to remove the battery and loosen the nut and mounting bolt that attach the AC to the engine. Just loosen them enough to let the unit flex up and down. Then move in the direction necessary to get the belt off.
