97 wrangler fan upgrade is possible

Awhile back Chris142 posted a fan upgrade for the 2000 and newer fan upgrade. Someone may have touched on this already, but I wanted to share my experience. Since I did my engine swap from the 2.5 to 4.0 I was running a flex a lite 485 electric fan kit. Well the kit works great for city driving and off roading, but not on the highway in Arizona. My coolant temp would get to 235 degrees. Well I swapped in a new fan shroud, fan clutch, and fan. Heavy duty hayden (2737) fan clutch, oem fan shroud, and a dorman 620-112 fan, which is a 9 blade. It was 100 degrees out today and my coolant temp stayed at 198 the entire time. I am pushing 32" all terrains, 3 inch lift, a/c on, and cruising at 70MPH. Like I said, before my coolant temp would climb high and make me extremely nervous. For us older tjs', you can do this swap to your jeep.
