If you're referring to the 4.0 I-6, there is an idler pulley located directly under the air conditioning compressor pulley.
However, tension is adjusted through the Power Steering pump. You will have to loosen the two bolts behind the power steering pump, two or three bolts which attach to the power steering bracket, as well as the one under the front of the pulley.
There is also another bolt under the driver's side of the power steering pump. This one actually controls the belt tension.
The tensioner pulley is off course located in line with all the other pulleys on the front of your engine block and will be the only pulley that isn't connected to another device such as your air conditioning compressor, alternator or fan. A large screwdriver can be used to lever tension off the belt or you can use a socket of the correct size on the nut on the front of the pulley. Typically there is a belt routing diagram in the form of a sticker perhaps on the shroud covering the radiator/fan that will be helpful in locating this pulley as well.
hi, here's what you need to do-----
1995 I have a 1997 and recently figured this out. Look behind the top right pulley that operates the power steering pump. On the left side of the pump down about 3 - 4 inches at a 45 degree angle you will see the head of a bolt. if you begin to loosen this it will relieve the pressure on your serpentine belt.
the pulley is under the power steering pump, the adjuster is a bolt on the top left of the mount. but be careful when adjusting, over do it and it will break like mine did.
Right underneath the power steering pump. It is the only pulley without anything attached to it. You tighten with a bolt.
Unbolt, slide off. Slide on new part, bolt back on.
Use a prybar to release the belt tensioner. This will allow you to slip it off. To install, you may need to remove a bolt from the alternator. That is one way to do it but not on my 1992 Cherokee Limited 4.0 HO. The power steering pump was actually the the tensioner pulley. You have to loosen the base then loosen the adjusting bolt under the pump. Prybar and removing bolt from alternator would not work. In a 94 GCL I used a 10mm(?) socket on the tensioner pully and pulled right. Slack was immediate. No need for removing anything except the belt.
Loosen the mounting bolt for the power steering pump, then loosen the tensioner bolt on the bottom of the power steering pump. (It's a long bolt that pushes the power steering pump away from the engine, which tightens the belt. Loosening this bolt will releive the tension on the belt.) When the tension is off the belt, it will slip free of the pulley and you can remove it. Install the new belt by following the same path that the old one did. (There should be a sticker on the frame inside the hood that shows you the routing for the belt. Remember that the belt needs to pass under the pulley for the fan. Once you have the new belt in place, tighten the tensioner bolt on the power steering pump to snug up the belt. Make sure it's good and snug; you don't want more than 1/4 inch of total play in the belt. Tighten the mounting bolt for the power steering pump, then start the engine and watch the belt to be sure it's centered on the pulleys and not slipping. Run the air conditioner and make sure the belt doesn't squeal. If it does, shut the engine off and tighten the tensioner some more. (Remember to loosen the mounting bolt first, and tighten it back up after you've adjusted the tensioner.)
Sears has a good repair site on the web. The model number must be entered and it has good pictures. Bacically those belts went over the top of the drum to a spring loaded tensioner pully on the front bottom right side then up to the motor pully and back up the right side. Remove the front panel of the dryer with a yellow handle nut driver or 3/16 socket to access the belt.
If you've got a 4.0 litre engine than you've got a Automatic belt tensioner on the engine. Sits to the right of the alternator. If your belt is loose, than you need to check that the belt is on properly on all the pulleys, or if you have the right belt. If the belt was made for a motor with A/C and yours doesn't have that, then the belt will be to long. Check with your local auto part supply store. Hope this helps...... For info on how to route the belt, get a chiltons manuel and it will have a diagram.
Where is the tensioner pully on a 1992 Lexus sc300
It is called an Idler pully and is not there to tension the belt.
yes there is a idler pully and bracket that gose in place of the compressor a little hard to find
With a self adjusting tensioner pulley, there is no adjustment for tension.
Unbolt, slide off. Slide on new part, bolt back on.
There is no tensioner pully. The Power Steering pump has a moving bracket that adjusts the belt tension. It has a long adjustment bolt. You have to remove the air cleaner and housing to reach it successfully. Funny, mine has a belt tensioner pulley under the power steering pump, which is tightened by a long adjustment bolt. So does every other 1996 Cherokee I've worked on!
Power steering and everything else on the Cherokee is controlled by a single serpentine belt. On the XJ (non-Grand Cherokee) the belt has a tensioner pully located under the power steering pump. The bolt on the pully must be loosened and then the long adjuster bolt (found on a 45-degree angle towards the middle of the engine) can be easily turned to move the pully and allow for slack to put on a new belt. The belt can only go one way, must touch all pullies. smoth side to smoth pullies and groved side to goroved pullies.
The tensioner pully is just to the left of the alternator. It is an arm with a round pully on the end of it. It has a square 3/8 ratchet attatchment. It is about 7 inches long.
CHECK THE IDELER PULLY OR BELT TENSIONER PULLY.
its on the left side. its the easyest pully to see.
Replace tentioner pully on 2.8 multiport
The tensioner Pulley is located and the tensioner. if you look at the front of the engine (or from the right side of vehicle) the tensioner will be kind of down in front of the motor mount, its the only on that will move in a pivot motion. Looking from the front, the belt goes over the Alterantor, down under the tendioner pully and then back up to the Powerstering pump.
