The Mopar tensioner assembly automatically adjusts the belt. Check belt alignment and look for wear on outer edges.
I would try a new EPDM serpentine belt.
You may need a new tensioner ?
Always add the correct, specified amount of fluid first.
To get a more accurate reading, drive the Jeep at highway speed for 30 minutes and check fluid level again.

Just my Luck..
Rains heavy for 2 days, & I pump $25 and the next thing I know jeep is bucking & throwing misfire P 0300 codes.
I highly recommend keeping a water remover product in the Jeep. I used Star Tron fuel treatment & the water remover. Problem Solved !! :)
Please reply back how the Jasper install goes. What was the total quote? Jasper has a good warranty 2 years or mileage?
I wonder if Jasper can summarize what all it needed to rebuild.
Unfortunately a Late 2007 KJ is going to be problematic, when it comes to finding the correct parts.
It's known as a cross over year, as the factory made many changes, just before the KK.
I would recommend that you obtain the free Factory build sheet at any dealer, or use the Mopar VIN Decoder...
The KJ's are more fuel economical & get the job done well.
However, The solid front axle Wrangler's have major traction advantages with 35" + tires & more articulation.
Coil packs got wet with coolant probably. Use compressed air to dry inside coil pack & top of spark plugs, see if that helps.
When was the last time you replaced the spark plugs? Change them every 30k miles anyways.
