Idler Pully Replacement
Hi
The Idler pully is shot on my 2003 5.4L 4x4 Off road model. The question I have is, can I replace this pully without removing the serpentine belt? The belt does not go around this pully, it only rubs against it.
I am thinking I can have a helper relieve the belt tension, while I remove the old one and replace the new one. Does this sound like a plan? Will the belt fall off any of the pully's when I relieve the tension?
On another note, is there a special tool I need to replace the belt just in case I do need to remove it?
Thanks

Take the tension off of the belt.
I use a breaker bar for that.
Slip the belt off of the pulley.
(This is when I would go ahead and change the belt too.)
Replace the idler pulley.
Reroute the belt into place.

Idler Pully Install
There is not much to slip off, the idler only rubs up against the belt on this 5.4L motor.
This is why I think this may be possible with a helper holding the breaker bar.

It's simple. You just have to remove a little tension off the S- belt and the idler pulley can be swapped out. There is no need to remove the S-belt unless your removing the tensioner and replacing that, then you will have to remove the S-belt. Getting that serpentine belt on an off with just two hands is a little tough though.

Although I donʻt have this particular tool, I created one to do this task.
BTW, having this special tool whether bought or made helps on different model cars and trucks.
Removing a serp belt on an older Taurus or a Windstar needs this type of tool.
Once you take tension off the serp belt, the rest of the job should be a snap.
Just keep you hands clear from in between the belt and pulleys when replacing the belt.

Take a 1/2 drive bar loosen and remove the belt and replace the stock bearing with a $ 2.00 6203-2RS bearing (think that's the number) and reuse your Idler wheel. Pop out one of the rubber seals and pack it with a good synthetic grease replace and way to go, 20 min done.
