On the way to work this morning on the 202 just past dobson rd in chandler AZ and my coolant temp started climbing, and my warning light came on. I shut it off, and parked it on the side of the highway. Ive never had cooling issues, infact because i live in AZ i focused on engine cooling for a little while. 14 GT TP, with GT500 fan/shroud, boss 302S grill, boss 302 intake manifold, long tubes, hood vents. Car has 44k miles, factory coolant, factory thermostat. My first guess is thermostat failure. I opened the hood and had a slight slight hint of a coolant smell. But the engine wasn't radiating heat like i was expecting. I can lay my hand on the intake manifold and its not very hot. Any ideas on what this could be.
