No sir they will not interchange. i worked at a transmission shop for 7 years. the inline 6 has a 500 trans in it and the v8 has a 518 trans in it. the bellhousings are different.

Your cabin filter is located beneath the cowl that is located under your passenger wiper arm. To get to your cabin filter, first you must remove your passenger wiper arm. Remove the wiper blade arm by pulling off the cap that is over the nut, and using a socket to remove the nut. Now pull up on your wiper arm, and allow it to pivot up wards. Push down at the arm, to force the female end off of the shaft of the wiper motor. It may help to have the hood open while removing the arm.
Once the passenger wiper arm is off, with the hood open, carefully begin removing the rubber seal from the plastic cowl. The seal becomes weaker as it ages, and can tear easily.
With the seal out of the way, you can begin to disassemble the plastic cowl. I believe comes off by pulling up/forward, carefully not to break the plastic clips underneath. Start from the outside, and work your way towards the center of the windshield. Now the cabin filter and housing can be removed from beneath the cowl. Reverse procedure to install.
Please let me know if I may further assist you. -TXTEXAN

To remove the front rotors,you first need to support the vehicle with a jack stand.Then remove the wheel.
Once the wheel is out of the way you need to take the two bolts off of the backside of the caliper, then compress the caliper and lift it off of the rotor.
Now you should be able to easily remove the rotor from the Jeep.

Well Bruno it sounds like you lost freon from your a/c system.The cabin filter wont restrict you from getting cold air.Check that your a/c clutch engages when you turn it on.if it dont you need freon and have to check for leaks
