cooling problem from hell, part duex!

[withamc]

FIVEOFPATROL - Sorry to hear about your problems. I had something similar to this happen when I put the cam in a few weeks ago. I had put a Stant heavy duty/high flow 180 therm in, took it out Friday night and it got real hot real fast, upper hose got hot, but the radiator was still cool to the touch. I seem to remember having problems with the heavy duty/high flow therm before. Went back to the store and just got the normal 180 therm (Stant also), but before I put it in I drilled a tiny hole on the flat part of the thermostat (Jeep sells them this way) and made sure that hole was at the top when I installed it. Supposed to help in filling the cooling system and getting air bubbles out. Also I poured in a bottle of Water Wetter. It's been OK since.
