Currently, I am not having any overheating problems. But I'm getting ready to change the coolant on my 05 6.0L with 189,000 miles on it. I added a coolant and oil filter systems then added a new blue spring kit las week. Truck sounds a lot less noisy and seems to run better overall. At the 190k mile mark I want to change the coolant as well as the coolant filter. I read a PDF I found on this site regarding the procedure. 1. After I drain the system and refill with water do I drive the vehicle for 60-120 minutes to flush it all through or do I just let the truck idle for that period of time? 2. Are people using the Fumoto Valves on their engine? 3. Are others doing the chemical flush and reverse flush or just one type? 4. My transmission and coolant temperature gauges register about equal and at mid way on their gauges but I know the temperature because my truck only has idiot gauges and lights, how are others determining temperatures? Thank you.
