Ever since I installed the Alum head the car runs hotter. I have a 2 row 1 inch alum radiator with the stock fan. I alsoinstalled an overflow tube. I installed a 3.5" fan shroud yesterday and it still running hotter then before the Alum head. Yesterday after getting off the interstate and sitting at a light it peaked at H and would come back down a couple of times. It was about 100 with heat index. My temp gauge does not show temp just C- H. Before and after the shroud it runs just below halfway between C-H. Could it be a bad sensor or does the V8 sensor read hotter. I am running about 3/4 gallon of coolant, water wetter and distilled water to fill it. Not sure what else to do. I thought it would run cooler with the new head. Any ideas.
