Totally off topic for the thread but when I refreshed my cooling system I went with the lower bar pressure cap and a 90c stat and have had zero issues since. Truck runs CONSIDERABLY cooler than stock and I have had no issues at all reaching closed loop even living over here in Ohio where we definitely get cold winters. The difference that I did notice was that prior to the upgrade it was at operating temp by the time I got to the freeway, about 2 miles or so from my house, I now let it warm up for about 60\90 seconds before I back out of the garage and if I don't hurry to the freeway she's just hitting temp as I roll onto the on ramp
