Jeep Wrangler TJ Cooling System Overhaul FAQ

I’ve got a question and I feel this is a good spot to ask it. I’ve got a question about overheating. I’ve got a 97 TJ with 168k miles I’ve got a new motor, with low gearing. I’m on 35s and I believe its 4.56 gearing or lower. It’s a manual. I’ve got a winch.

When I drive on the freeway at 65-70 uphill or on a medium incline at 70 degrees or Warner outside my temp gauge pushes up to 250 and eventually gets to 260 and I pull over to let it cool. I’m not expecting to get over 55 going uphill because of my gearing etc, but I’d like to upgrade something on my Jeep whether it be good louvers or a high powered electric fan.

Anyone have any recommendations?
I’m good on all my fluids and my fan runs well when it gets hot. I got a new radiator when I got my new motor and no leaks.

I had overheating issues before and after replacing the cooling system.

It turned out to be a leaking head gasket.
