Airducts Removal using 10MM Socket and simply slide out the plastic to get some space

try to find that bolt on the belt tensioner

use the 14MM wrench heavily “belt tensioner” turn the drive socket haha i call it the “wrench” right to tighten up the bolt than the pulley should lower down for the belt to be removed

after the removal of the belt, if its greasey and dirty clean it up =]

got this @ a local auto part store it works for 4.0 and 4.3 etc…

This diagram should have it in the engine bay.. my camera phone is blurry

follow the diagram starting from top sides then to the bottom and where the last bottom pulley cant be tuck in, you would have to use that 14MM Drive socket wrench, where the bolt was to loosen it up than tuck it in

dont worry near the end .. but yeah .. now its inspection time after the new belt is in. MAKE SURE DO NOT START THE ENGINE RIGHT AWAY!! inspect make sure all the pulleys and belts in correct order inside the walls of the pulley

and at last after making sure the belt is in place, and re install the air duct plastic and all good =] it litallerilly took me about 15 mins for the whole job.. and yes i was doing it in the COLD weather it was about 20 something chills blowing around haha

hope it helps out
