How do you adjust the serpentine belt on your 2000 jeep wrangler?

Answer 1

I have a 1992 Dynasty with the 3.3 Liter engine. The serpentine belt has a tensioner pulley that is spring loaded... it puts tension on the pulley automatically - if the belt is in place correctly the way it is supposed to go. You probably want to know how to get the belt on or off... I put a box end wrench around the nut in the center of the tensioner pulley. With the wrench over the nut, push back on the other end of the wrench with something long and thin. There isn't much room around that area but I found that a three foot piece of 1 X 4 wood board works well. You should feel the spring tension of the pulley when you push back on the wrench... it will move a couple of inches or so. It might be a good idea to have someone else push back on the wrench while you remove/istall the belt... just easier that way and probably safer too. Anyways, with everything in place correctly, no further adjustment is needed. If you have the serpentine belt off, it might be a good idea to check the idler pulley. The bearings don't last forever... ha! Mine lasted maybe 175,000 miles before it siezed up. The pulley, mounting bracket, new belt and tow truck expense was about $450 at a Dodge dealer. I think the bad bearing did make some noise occasionally before it went out but I ignored it. It finally went out on a cold winter morning on my way to work. Live and learn, I guess. Anyways, try not to ignore warning noises from your Dynasty and it will give you many more miles of fun. Gary... Princeton, MN.

Answer 2

Should have a spring loaded tensioner and no adjustment is necessary unless tensioner is bad

It actually has a tension pulley underneath the Power Steering. Use a 15mm socket to loosen/tighten the bolt right beside the power steering. That is how you adjust the tension on the belt.

Answer 3

you do not adjust a serpentine belt. the adjustment is done automatically by the tension pulley if belt is loose, purchase a new belt . also check that all pulleys are in good shape before installing new belt

Answer 4

Loosen the pulley below the power steering pump. Then locate the bolt to the left aiming at the pulley. It goes through the nut on the backside of the pulley. This is how it moves the pulley along the slot tightening / loosening the belt tension. Once you get it set tighten the pulley bolt back down to lock it in place.

Answer 5

It uses an automatic tensioner- no adjustment is provided, or required.

Answer 6

Automatic tensioner- no adjustment required, or provided. If the tensioner is out of limits, replace the tensioner.
