I refer mostly to his "myth" section in this coolant article.He claims that you cannot run coolant through a radiator too fast. I call WRONG on that.I AM interested to hear others inputs on his "theory" of faster is better no matter what else on coolant flow. I fall to the "heat takes time" to transfer and it can go through so fast it goes back into the engine TOO HOT.Also his if you do not run a thermostat you should not run a restrictor. This would only work if the radiator was far to large. Heat up time would take forever.
He is 100% correct on this. Restrictors are complete crap and should never be used.
If the fluid is staying in the radiator longer it is also staying in the block longer collecting more heat. This can lead to hotspots and boiling/steam pockets. Once you get a steam pocket your heat transfer goes to zero and things go down hill very quickly.
With higher flow, your temp rise may not be as much, but you flow rate is much higher effectively removing the same amount of heat without the risk of steam pockets.
What I have used for years on race trucks is an umbrella style thermostat with 3-3/16" bleed holes in it and no bypass hose. This allows for some flow restriction to aid with warm up but still allows for full flow at race temps.
Higher flow rate removing the same amount of heat? ?? Not sure I follow that. Care to elaborate?
