Mine never got hot unless I was towing, regardless of how I was driving it after the mods. Hang a 3.2T van on the back and it got pretty hot going up big hills at speed, and I mean proper big long hills. From here I put in new fluid, hoses, thermostat (standard one), UFI fan and hub and a 3 core copper/brass Rapid Cool radiator, problem solved. Going up the same hills that saw temps skyrocket and me backing off, I can now stay in it.
