Number one idea, Listen to what Camoit said and do not over heat these trucks. They are notorious for cracking the heads and do it with a slight over heating. Watch the temp gauge, if there is not one, Get one. I run a 180 degree thermostat. Lets them run cooler and gives a little extra time if you see a rise in heat out of the ordinary. Flush out radiator when replacing a thermostat.
I cringe when someone says their truck is over heating and didn't pull over immediately or seen fumes from heat off engine cause it reminds me of my over heating experience. I watch gauges and still couldn't catch it in time, next thing I know, I am making milkshakes in my oil.
