How to change the tensioner pulley on a 2004 Jeep Grand Cherokee

There is a star bolt on the left side of the tensioner. Does removing this bolt remove the tensioner? Is the tensioner under pressure (are springs going to go shooting everywhere when it is removed)?

The opposite direction the pulley turns. However, if you are trying to get the serpentine belt on or off, this will help. It's easy and doesn't require a prybar.

  • Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
  • Get the belt around all the pulleys except the A/C compressor or Alternator.
  • The tensioner pulley is near the Alternator toward the center of the engine. It's on a spring loaded arm. Get your socket on the center nut of this pulley.
  • Slowly pull the ratchet toward the center of the engine. The pulley will pivot on the arm allowing you to get the belt on the final pulley.
  • Slowly release the tension.
  • You're done

How do i adjust a serpentine belt on a 96 jeep cherokee


You don't. If the belt looks frayed or otherwise damaged you replace it. There is however a belt tensioner which kind of automatically applies tension to the belt which removes the need to adjust belts like the old v belts with the adjustor brackets. You shouldn't have more than 1/2 to 1" or belt play otherwise if so your tensioner may be going out and need to be replaced.

Can't find serpentine belt tensioner on 97 Jeep Grand Cherokee


right, for the 4 liter,
  1. Loosen the rear power steering pump mounting bolts using a ratchet and 13mm socket or a 13mm box wrench.
  2. Loosen the pump upper pivot bolt, lower locknut and the pump adjusting bolt using a ratchet and 13mm socket or a 13mm box wrench.
For the V8
  1. Attach a socket or wrench to the pulley mounting bolt on the automatic tensioner and rotate the tensioner assembly clockwise until the tension has been removed from the belt.
  2. Remove the belt from the idler pulley first and then from the vehicle.

Must i remove the radiator, the grill, and the fan, in order to change the fan (serpentine) belt on the 1996 Grand Cherokee Laredo?


Absolutely not.. It will come out by releasing tension on the belt and working it around the pulleys..It's tight but it will come.

How do I replace pulley bearings on my jeep garnd cherokee? Is there any settings in tensions I need to know?


Hi Josh,
I'm glad you were able to diagnose it as a pulley. For pulleys you don't replace the bearings. Replace the complete pulley. Just remove the
bolt(s), take the old pulley off, bolt on the new pulley and put the belt back on. Nothing technical you need to do here. Just tighten the bolt(s) to about the same tightness they were before you removed them.
I hope this helps.

Does the power steering pully need to be removed to replace the alternator on my Jeep Grand Cherokee?


If for any reason the pulley is in your way, remove the pump not the pulley. Alternator is on the other side of the engine...why remove it? The pump is the adjustment for the belt. (loosen bolts and use the transverse bolt underneath to adjust tension)

I need to replace my serpentine belt. Which


For a 94 Jeep grand cherokee, the tension is controlled through a long bolt on the power steering bracket. The bolt is about 6 inches long, located underneath the power steering on the driver side. Lossen the lockbolt holding it in place, as well as the Power steering attach bolts, and turn the long bolt to tighten/loosen. I believe these are all 13 mm bolts.

How do i change a Timing Belt Tensioner on a 1995 jeep grand cherokee v8 5.2 my belt burned in 2 it and i need 2 take it off n replace it


You really need a repair manual for your model. Most Auto parts stores carry these. However, If your timing belt has been broken (burnt) while the vehicle was running, then you'll need to check for bent valves or cracked pistons. If you are not one, you may need a mechanic.

2000 jeep grand cherokee 4.0 liter engine timing belt replacement


If you have the same pulley arrangement that most 4.0 engines have that pulley is an idler not a tensioner. Your power steering pump has a pivot bolt, and a slide under the pump. You adjust belt tension using the pump.
