When I put my temp gauge on I noticed that when the TC was locked and cruising at highway speeds the temperature was normally about 160. When running around town with very little air flow through the radiator and TC not locked I was easily getting temperatures up to 210. It seems that just idling with the transmission in drive will get the temperature up to what the engine is normally running, 190. All of this was empty. When I start towing I'm going to make sure I've got an additional cooler installed to keep the temperatures down.
