Want this question answered?
I replaced the engine idler pulley that I bought from Autozone for about $17 and eliminated the noise. I initially thought the bearings on my alternator were going out but when I replaced the pulley all the whining noise disappeared. Good Luck!
Requires two person team. Step One: Look at serpentine belt diagram on front of engine. Arrow points to idler tension pulley. (Front Left side of engine) Loosen this 15mm bolt. Step Two: Loosen Idler pulley bolt - 15mm. Step Three: One person push down on idler tension pulley with tire removal tool or cheater bar on front left of engine while second person lifts belt off alternator. Step Four: Remove Idler pulley and replace with new one. Tighten bolt to idler pulley Step Five: One person push down on idler tension pulley with while the other fits belt on alternator and around idler pulley. Step Six: Make sure belt fits as noted on belt diagram and Tighten bolt on idler tension pulley (front left side of engine). Approximate time: 10 minutes
Are you talking about the "idler pulley"? They are quite simple to change. Loosen the serpentine belt by using a socket on the center of the tensioner pulley, slide the belt off the idler pulley, use a socket to pull the center bolt of the idler pulley and replace the pulley with a new one.
Take the belt off, un-bolt the idler pulley, bolt the new pulley on, and finally put the belt back on and Viola!!
Take the belt off, take the bolt off of the idler pulley, take the pulley off, put a new one on replace the bolt, and put the belt back on
I don't believe there is an idler pulley on that model, just a tensioner pulley
go to youtube and type in ericthecarguy and change pulley
First you would need to take the serpentine belt off of the engine, and then remove the bolt in the center of the idler pulley. I have included an instructional vieo of how this is done.
The idler pulley has nothing to do with the brakes. If the idler pulley is bad it could throw or break a belt, and then your engine will stop.
In an Inline 6 Jeep engine, the idler pulley is located to the right of the A/C pulley. It is a smooth pulley, not a grooved one.
idler pulley, the only one that will move
If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley. Pry the idler back and remove the belt.If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley.
