    It is a 1997 V8 ...I'm not sure there is a GL or EX marked anywhere...Didn't even see it on the title or registration.the part that the assmbly is attached to has been eaten up. I do't even see where plley was attached to it. I'm not seeing where the part that the pulley is attached to is even bolted to.

2003 Mercury mountaineer high pitch whining sounds like front passengers side- just started today - worse when you accelerate - husband thinks it might be idler pulley bearing??

If it is the idler pulley for the accessory belt, it would make the sound at all times the engine is running, not just under acceleration. I would look to the wheel bearing or the brakes on that corner of the vehicle.

How to replace a idler pulley on a 1997 international 4700 series

Hi Melissa:
Nice truck!
I'm assuming that the bearings in the idler pulley are shot which is why you're replacin the pulley. Pulley's are typically attached by a bolt through their centre. Replacing the idler consists of getting the bolt out and exchanging new for old. Here's the route I would recommend:
SAFETY FIRST - Disconnect negative battery terminal.
- Make a diagram of belt routing.
- Slacken idler and remove belt
- Remove Idler retaing bolt (Watch for washers or spacers)
- Install new Idler with washers or spacers in same position.
- Tighten retaining bolt.
- Use diagram to re-install belt;
- Re-connect negative battery terminal.
- Check for stray tools or loose objects.
Test run.

Serpentine belt on '97 3.8 Mustang pops off idler pulley even though everything appears to be properly aligned after A/C compressor replacement.

If the idler and nearby pulleys are all in-line, not excessively worn and the axis is exactly at a right-angle to the belt run the belt should not pop off, therefore either the idler or other pulleys are worn tapered or sagging or it is possible the belt has become stretched on one edge.

You could try turning the belt around so it is traveling in the opposite direction and see if it makes any difference. Some idler pulleys will also turn round if required.

I hope this provides food for thought.

How to change alternator belt

alternator and air conditioning compressor
  1. Disconnect the negative battery cable.
  2. Loosen the idler pulley bolt.

The replacement of the inner belt on multi-belted engines may require the removal of the outer belts.
To replace a drive belt, loosen the adjusting and mounting bolts of the component which the belt is driving. Move the component inward to relieve the tension on the drive belt.
Slip the belt off the component pulley and match the new belt with the old belt for length and width. The old belt will be slightly longer. After a new belt is installed correctly, adjust the tension.
  1. Turn the adjustment bolt at the top of the idler pulley bracket. Clockwise rotation will tighten the belt; counterclockwise will loosen it.
  2. Keep the idler pulley bolt snug (but not tight) while adjusting belt tension. The adjustment bolt should turn with moderate force.

After adjustment is satisfactory, tighten the idler pulley bolt, and then tighten the adjustment bolt.

Reconnect the negative battery cable.

When replacing more than 1 belt, it is a good idea to make note or mark what belt goes around what pulley; this will make installation easier if you mix up the belts.

How do you change an idler pulley on a 97 mercury grand marquis

Using either a serpentine belt tool or a long ratchet and a socket on the tensioner pulley bolt, turn the tensioner to relieve tension and pop the belt off. Remove the idler pulley bolt and replace the idler pulley. To finish it up simply reinstall the belt.

How Do I Release The Tension Pulley To Change A Serpentine Belt On A 2000 Mercury Mountaineer? What type of tool whould I use. I need to take off the belt so I can swap out the altenator.

Hello there:
on the tension idler pulley look real closley and you will see a square slot
on it this is for a rachet wrench with a extension on it simpley insert it in the hole and push lt as if you were tightening a bolt and you will see the pulley start to move it takes a good amount of pressure to get the pulley to move and hold once it is loose so be carefull If you have a cheater bar that you can slide over the rachet wrench this will help you move the pulley a lot easier ok hop that this has been very helpfull
best regardds michael

1998 Saturn SL idler pulley broke off and bolt is stuck in engine

The idler pully can be removed without removing the engine. I have replaced mine in my 97 SL2. As to the bolt breaking off, that is strange. I assume that if the bolt broke off, then the idler pully also fell off. If I remember, the space is somewhat limited, so getting a removal tool in there could be very difficult, especially if the bolt is flush with the mounting hole. That doesn't sound like a fun project. If bolt protrudes, maybe you can get some vise-grips on it and turn it out.

there should be a torx socket that fits it pretty well. as far as being lefthand thread, I think that those are normal threads. usually its the idler pulleys on fords that have a lefthand thread design.
