I have 30+ years working on cars in Phx 4 years of which was in a radiator shop.. The faster and the more turbulent the air/water flow inside or outside an exchanger, the more exchange occurs. This is why some racers install flow restrictors in place of the thermostat. Use an old washcloth or paper towels to soak up the excess antifreeze. There are those, including hose manufacturers, who believe you don’t need an anti-collapse spring in the lower radiator hose. It seems like if you controlled the temperature going into the engine, it would still cool the engine about the same as a higher temperature switch on the hot side. Like motor oil, radiator fluid and transmission fluid, antifreeze can leak from an engine or escape from the container, leaving an unsightly stain on the driveway. And even on the open road, coolant never has a chance to park in the radiator long enough to give up heat energy to the atmosphere. I was just about to correct them also and saw your comment first. Cooling is a function of the change in water temperature multiplied by the flow of the water multiplied by the specific heat of the fluid: http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/spht.html. Choke isn’t acting reliable, fuel economy is deplorable. What we want is for the air to be able to take more heat out of the radiator. But that isn’t completely true, either. If you’re going racing, double up hose clamps with two at each end of the hose. Though the engine does not smoke. The third point is taken out of context. Is there a convention on the order of multiplication of the weights with the inputs in neural nets? Why can't coolant dry inside the engine during engine operation? The point people are saying about coolant not having enough time to cool without a thermostat-in laymans terms-picture the radiator as a heat exchanger, which I think it is basically, lets say coolant is flying through the radiator really fast well the air is not going to cool off the coolant dramatically in a quick time so the hot coolant goes right back in to the block and heats up some more. Crossflow radiators became more common around 1970 and have been commonplace ever since. In addition to the absorption potential of the coolant, and its flow rate, and the radiators capabilities. The truth is, you must have an anti-collapse spring in the lower radiator hose if you have an older vehicle with a conventional cooling system. Using the reentry of the space shuttle as an example of the reaction of air flow makes me wonder how much you understand what is going on. This is the Flex-a-Lite 15-inch 3,000cfm electric fan for a wide variety of radiators in the 20-inch range. But so does the temperature of the radiator. To achieve and maintain optimum temperature range, a good cooling system needs the right-sized radiator and fan combo. IF there was ever a place to test any of this, that would be the place (could be why several manufacturers choose to have proving grounds there… Carl is largely correct… except for the fact that removing a thermostat will decrease pressure in a system that needs pressure to help prevent DNB (Departure from Nucleatic boiling)… this basically means that nucleatic boiling (small bubbles on surface) is ok, but the moment it becomes film boiling, the steam creates an insulated surface of the block or head that is not in direct contact with the liquid coolant molecules any more.
