1994 Ford Explorer idler pulley assembly

Hi - the bushing went out on the idler pulley. The pulley stayed inside the engine compartment, but the bolt, washers, whatever stayed on the road, and when I went back, I couldn't find them. I've been looking online and I can't find what size or type of bolt I need to put the pulley back on...when you buy the pulley, the bolts don't come with it. Can you help?

How to remove the idler pulley on a jeep grand cherokeen1994

which engine? we can not guess engines.
unless, stated, or show with a photo. (add photo)
open hood see EPA sticker and engine is clearly stated there. USA.

read the FSM
read alldata. com
do tell and we CAN answer.

idler on 4.0, just it, is IT bad, or just a belt swap, do tell.
serpentine belt.
the book says, engine with no power steering (you) do have
spring loaded, idler, but the other engines and with power streering
so is this a P/S free car" I must assume so this is the FSM quote for taht
special case: (ive never seen a P./s free GC) but here goes.
If the engine is equipped with an idler pulley, loosen the idler pulley adjusting bolt, insert a prybar between the pulley and the engine (or in the idler pulley adjusting slot), and adjust the tension accordingly. If the engine is not equipped with an idler pulley, the alternator must be moved to accomplish this adjustment, as outlined under Alternator Belt.

why not post a photo of the part that cant be removed.????

but if V8?? (it should not be, as that was introduced in 1994)(
it has a turn bolt CW to release tension, on V8 idler.
my book dont show how to remove said pulley
but I think yours is broken.

1996 Ford Mustang v6 coupe idler pulley and belt tensioner

I guess it depends on what failed.
The idler pulley is a simple pulley with a bearing held on by a large bolt.
If the bolt broke, or came loose, you may have problems keeping a new bolt in place.
If the bearing wore out and came apart, the bolt is probably still in the bracket. A failed bearing is common after 10 or 15 years, a loose bolt is somewhat rare.
The belt tensioner is another pulley mounted on a spring-loaded arm that keeps the belt tight. Same design but a different function.

How replace and put back on idler pulley n serpintine belt

Hi there,

Use socket wrench to turn serpentine belt counterclockwise at tensioner to get some slack.
Pull serpentine belt off topside of idler pulley and put it underneath idler pulley, and actually try to tuck it up inbetween engine block and idler pulley. Then close your engine hood.

Then crank engine a few seconds and the belt should flip that idler pulley right off.
Dont even need to start the engine. You can tell when the job is done by hearing a big thud, and seeing the dent pushing out on your engine hood. Turn your key off immediately after hearing the thud, or if the engine starts. You just want to crank it a second or two. Easier than using a puller.

If the idler pulley is really shot to bits, it may come off in pieces; if not, there should be one center bolt and a largish washer. Don't lose the washer or bolt since your new part does not come with those (mine didn't!). Replace everything in the same order. Make sure you follow the torque specifications for the bolt when replacing it.

For the dent on your hood, just whack it back down with a hammer, then spray it with white Rust-Oleum spray paint, or the color that matches your car color.

Hope these help.
