It's a T-40 size, but I removed the bolt by first removing the bracket holding the pulley--I assume you're talking about the alternator idler pulley, the one right below the alternator. The bracket is held in place by three 14 mm bolts which I was able to reach from the top of the engine (after removing the black plastic air tube). I then put the bracket in a vise and "buzzed" off the 14 mm nut using an electric impact wrench ($30 +/- from Heartland of America). Be careful when putting the nut back on--the impact wrench will likely be too much torque!

My idler pulley on my 96 ford explorer is grinding on the bracket that holds it in place and creating a loud grinding noise, what steps would I use to resolve it??


change the idler pulley . its held on by a bolt in the center of the pulley. the bearings are sealed so you can't grease them. but first you have to take the tension off the serpintine belt. that is also another pulley located below the idler.don't know what size bolt on a ford but use a long wrench grab the bolt on the tensioner push to the right like you were tightening it. that will release the tension on the belt. don't take the belt all the way off just off the idler pulley. change the pulley and do tha same to reinstall the serpintine belt. if the belt comes all thr way off under the hood or on the front around the top of the radiator there will be a schematic that shows you how the belt should go around everything. let me know what happens. sometimes the tensioner pulley will grind also so be sure your changing the right pulley

The idler pulley has a nut in the middle of it. You loosen that, then there is a tensioner bolt at about 4 o'clock, turning that will move the idler pulley away from the belt.

The tensioner pulley has a nut in the center of it that you loosen, then behind the pulley is a tensioner bolt that when you turn it, it moves the pulley away from the belt in a slot on the tensioner bracket.
