NEED TO TIGHTEN FAN BELT ON 1997 JEEP WRANGLER

loosen the altanator to tighten the belt. pull belt tight then retighten the bolts

If a 6cyl, from the front of engine, loosen the idler pulley with a 15mm wrench. It's on the left side of the engine. Then from the top, use a 15mm socket on a 6 inch extension, and tighten the adjustment bolt that is mounted diagonally just behind the idler pulley. takes alot of turns to tighten the belt. Then retighten the idler pulley bolt with wrench.
