To the OP, ken72, my apologies for the thread hijack. Guess I should have left it at my 1st post on page 1.

No worries, I just ignore the other stuff. I got the info I needed. Realized I need to do some cooling system maintenance. BTW... learned quite a bit from your serpintine belt thread. Think I am going to change the belt, water pump, and t-stat all once when I do my belt change.

it's not difficult at all. even then, all fuel injected jeeps have an open system, and air will move it's way through the system and replace it with what's in the overfill bottle. you'll want to put some coolant in the radiator as well as filling the bottle, and run it until fluid starts moving through it and keep adding coolant to the bottle.
