I removed the alternator for my 2002 Jeep Grand Cherokee. I started by removing the belt, by placing a 1/2" ratchet in the groove on the belt tension pulley. Once the belt was removed I removed the two bolts holding the alternator in place and the wiring. The alternator bracket held the alternator tightly, it took a little persuasion with a heavy hammer and a piece of wood. The wood protected the alternator from damage. I also, had to remove the battery box and top radiator hose to get enough room to hammer the alternator out of the bracket. Putting the new one in also, took lite taps with a hammer to place it in the bracket.

How do I replace the alternator on my 4.7liter 2008 jeep commander


1. First you need to disconnect the battery. Negative terminal first and then positive. When refitting the cables, positive first and negative last. Do not reconnect the battery until the replacement alternator is fitted and wired up.

2. Now you will need to remove the serpentine belt. Locate the tensioner pulley and you will need to use a socket and wrench to release tension on the tensioner pulley so you can slip the belt off. Before you start work draw a diagram of the belt routing over the various pulleys so you know how to refit it. There is a video in the link below that shows you how to remove and refit the belt on your 4.7. But you will not need to remove it entirely from the vehicle as long as it is slipped off the alternator pulley.

3. Once the belt is removed you will need to disconnect cables connected to the alternator that are readily accessible. There should be one cable set on the rear that clips out and and one on top that must be removed by removing a nut.

4. You have to remove the alternator from its mounting points by undoing the bolts that are securing it which will be all visible and accessible. There should be one on the side rear and 2 on the front. Once the 3 bolts are removed, you may need to move the alternator up and down vertically to loosen and free it from one of its mounting points.

5. Now you can bolt the new alternator in place using the same bolts as you removed and connect the cables to it.
Refit the serpentine belt, double check the cable connections to the alternator and then you can reconnect the battery.

6. Start the engine and check that the serpentine belt is running freely over the pulleys and is properly aligned on the pulleys. There should be no alternator warning light displayed on the dash if you have fitted the wiring to the new alternator properly but check .

7. There is a photo in the second link below of the 2008 4.7 engine. Click on the photo in the article to bring it up.

If you need more details about youe Jeep ZJ Grand Cherokee, can check this documents about Repair Manual: Grand Cherokee 1993-1998 FSM

To get out, 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

Hope helps (remember to rate this answer).

How many labor hours will it take to install a new alternator in my jeep grand cherokee?


How to Replace an Alternator (DIY Time: 2.5 hours)
Complexity: Moderate

Parts:
1. Alternator - $151.95

Tools:
1. Combination Wrench Set
2. Screwdriver
3. Multimeter
4. Serpentine Belt Tool
5. 3/8 in. Drive Ratchet
6. Socket Set

Steps:
Step 1 Open the hood and locate your vehicle’s alternator.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
o Tip: Always make sure the struts on the hood can fully support the weight of the hood so that it does not close on you while working. The use of a hood prop can securely hold it in place.

Step 2 Using your digital multi-meter, check the battery voltage. A dead battery will usually have less than 9 volts. This would not be enough power to start most vehicles.

Step 3 To verify that your alternator is bad, make sure your battery is fully charged and can pass a load test.

Step 4 With the good battery installed, connect your digital multi-meter across the battery terminals with the engine turned off. A good battery should read between 12-13 volts.

Step 5 Start your engine and read the digital multi-meter’s output. The voltage should rise near 13.5-14.5 volts.

Step 6 Using an open end wrench, disconnect the battery’s negative cable.
o Tip: When disconnecting battery cables, be sure to always disconnect the negative cable first and do not allow it to come in contact with the negative terminal post while working on the vehicle.
o Tip: Wrap the battery cable with a shop towel and pull it away from the battery terminal.

Step 7 Disconnect the power and ground wires on the back of the alternator paying close attention to where each wire connects. Disconnect the wiring harness connector.
o Tip: Check for a loose wiring harness connector, cracked wire insulation, and corroded terminals. Replacing the wiring harness may be necessary.

Step 8 Loosen the alternator bracket bolts, and alternator adjusting bolts or alternator belt tensioner so that you can remove the alternator drive belt.

Step 9 Using the proper size socket and ratchet, remove the alternator mounting bolts, spacer (if equipped), adjusting bolt, lower pivot bolt (if equipped), and the alternator.

Step 10 Install new alternator.

Step 11 Using the proper size socket and ratchet, loosely install the alternator mounting bolts, spacer (if equipped), adjusting bolt and lower pivot bolt (if equipped).

Step 12 Install the alternator belt.
o Tip: When installing the alternator belt, make sure the alternator belt is fully seated in the groove of the pulleys.

Step 13 Pull the alternator until the alternator belt is tight.

Step 14 Tighten the alternator mounting bolts while gently moving the alternator unit to achieve proper alternator belt tension.

Step 15 Reinstall the power and ground wires to alternator. Install the wiring harness connector.

Step 16 Push down in the middle of the alternator belt to check belt tension. If the alternator belt moves more than a half an inch, it is too loose, adjust the alternator belt to proper tension before proceeding to next step.

Step 17 Now that the alternator belt has been installed and adjusted, reconnect the negative battery cable. Start the engine and check the battery voltage to verify proper alternator charging.

Step 18 Turn off the engine and recheck the alternator belt tension. Readjust the alternator belt tension if needed.


Good luck (remember comment and rated this).

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)

How do I release the tension on the belt to remove and replace the alternator on a 1995 Jeep Cherokee Sport?


Very simple....just loosen the mount bolt on the pivot arm and adjusting bolts....the bolts that mount the alternator....the slack will allow you to remove the alternator....installation....bolt on your replacement alternator and place your belt on the pulley. Pull on the alternator to give it tension and then tighten bolts at the same time...have an extra set of hands for this.

Hi i have a 1999 jeep grand cherokee laredo do i turn the screw counter clockwise on the tensioner pulley to remove


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
