Replacement of 98 Wrangler Sport (W/ A/C) Serpentine Belt

I'm going to try to replace my serpentine belt this weekend, and would appreciate guidance.

I've not owned the Jeep long, but the belt has alot of small cracks, and I suspect it's original (Jeep has 59K miles).

After looking at the configuration, I thought the approach would be;
1) loosen the belt tensioner pulley using the long 'adjustment' bolt, which is on a 45 degree angle on the right side facing the Jeep.
2) Replace the Serpentine Belt.
3) Tighten the 'adjustment bolt. with the same number of revolutions , but in the opposite direction.

I don't know whether loosening is clockwise, or counter-clockwise.

Is it this straightforward?

Thanks fpr the help.

TC

The rule is "lefty loosey righty tighty".In other words counter clockwise to loosen and clockwise to tighten.

Remember that you have to loosen the tension pulley bolt before you attempt to adjust the tension adjustment bolt. The pulley bolt locks down your adjustment on the tension bolt.

Draw a picture of the belt while its still on. Youd be suprised how long it takes to figure out where the new one will go without something to look off of.

Check your private mail, I sent you some info you'll need.

You might consider getting one of these from your local NAPA
http://www.napaonline.com/MasterPage...+Tension+Gauge

With the info I sent you and the gauge, you are golden.

Don't forget to retighten the belt after 100 miles.

I use the 90 degree method. The belt should be tight enough that it can be twisted 90 degrees at the longest straight line.

Check your mail. Compare the diagram to what you have to be sure.

Does the tensioner work the same on a 4.0 on a 2002. Never done this before but that's the fun of a Jeep

I don't believe so....(going from memory).....I think the tensioner is near the alternator....it is one of the spring loaded types. I believe a 3/8" or 1/2" square ratchet end can be used to gain mechanical leverage to move it to get slack in the belt.

Or I could be completely wrong and this is for yet a newer TJ.

i always just remember smooth pulleys to the smooth side of belt, ribbed to ribbed...it should only fit one way.
