Replaced my radiator the other day. No leaks. All hoses are good. Thermostat is good and working but NOT brand new. It starts out cold and moves to normal operating temp position which is about a hair under half mark. This has always been the normal position and it will go up when temp starts getting too high.
Today was the first real hot day to test. I drove a little over 100 miles in 93+ deg weather. Some stop and go. Had a shoot that lasted about 2 hrs so it a got a break. The whole day I ran with the AC on purposely to test the cooling system. On my way home the temp gauge started to climb. I waited 'till it got just a little past the half mark and I chickened out and put windows down, shut AC off etc. In about 10 seconds or so, needle went back to normal position just below half. What gives? Is this normal. When is it too hot? Should I have let it climb? I stopped at my sisters house. Turned the AC back on and let the truck sit in the driveway for about 5 min. Never went up. Checked for leaks again. None. Checked coolant level-it was perfect. Has my previous cooling system woes scarred me for life with this RRC?
