I drove my truck for appx 30 mins today and its been sitting for 2 hours now. I went out side and popped the hood to load test my batteries. The engine is still very hot cant touch alternator or radiator. I pulled the coolant cap off and the water/coolant was still real hot. Is this normal? I just deleted my egr cooler, changed coolant to zerex elc-1 coolant, 5w 40 rotella syn. I put 3 gallons of concentrate coolant and the rest distilled water. My ficm is going out also. It's not like i dont have other things to be paranoid about !!!!Oh, the oil looks like it should also. I also just put in a brand new thermostat and the temp gauge on truck is normal.
