Spark Plug Replacement

I need to replace my spark plugs on my 98 4.0 Liter. I'm not very familiar with these engines just yet, but after looking at it, it looks like I will have to take the a/c compressor out of place to replace them. If so which one of the pulleys is the a/c belt tensioner pulley? I'm just trying to find everything before i start on it. It looks pretty simple after that. Is there any easier way or do i need to remove the a/c compressor? Thanks

I also have a 98 TJ and have replaced my plugs a few times. You can get them all out without taking anything apart, but you do need to use an extention and universal joint to get to some of them.

thanks so much for that advice, that will definitely save me a lot of time instead of taking everything apart. I do have plenty of extensions and a universal joint.

One more question as well, is there any other regular maintenance that is needed with these cars? Like, for example, on mitsubishi's, the timing belts and water pumps have to be replaced every 60K miles. Thanks again.

Jeeps need:
Coolant: 30k
Oil: 5k
diffs: 10k
air filter: 10k
lube suspension: every oil change

Mud: every chance you get

Anyone know a quick way to replace the #1 plug on the 2.5 with a/c? That thing is buried.

Update..Just took off the Intake crossover and used an extension with universal. Pretty sure they were original plugs. They had worn to a
.050 gap. 83K miles.
