47-55.1 Radiator question

[e015475]

Running a 160 degree thermostat is going to hurt you, not help you. It may take the engine a while longer to overheat, but you're reducing your cooling capacity with this thermostat. A low thermostat isn't doing your engine any good either.

The rate of heat transfer out of a radiator is always a funtion of the temperature difference between the radiator and the outside air. To maximize heat transfer you want the radiator as hot as possible relative to the air going over it.

6000 cfm of fans is likely overkill and your truck is going to sound like a vacuum cleaner going down the street, especially if they're in front of the radiator. Doubling or tripling the flow through the radiator isn't likely to make it cool much better and will just make it noisier - cooling capacity isn't linear with flow velocity

I'd suggest that you install a PWM fan controller with a temp sensor to slow the fans down and match demand.

Also, water has better heat transfer than antifreeze. I'd only use as much antifreeze as was necessary to protect from freezing in your area and no more. The ideal situation would be water and some Lubeguard for corrosion protection, pump lube and some wetting agents.

Just my 2 cents...............
