I have a 93 yj 2.5L. It has a 4 inch lift, 30 inch
tires(i know i need bigger ones) and thats about it. Recently the jeep has been getting hot when i go on the freeway and go around 60mph for 15 mins. If i go 55mph i can go forever. I got the notice in the mail to get the jeep smoged for registration. I had to get a new catalytic converter to get this done. Since getting the catalytic converter, my jeep has been overheating when ever i go down the road, whether it is 40mph or 55, it doesnt matter. I have checked the radiator and it has antifreeze and enough water, what else could be the problem? I am in the dark at the moment. THanks.
