A change in pressure of 1 psi results in a 3-degree change in temperature” says Cochran, “If your engine calls for a 15 PSI cap, but the one that is actually on the radiator is only holding to 7 PSI, you can see engine temperatures 27 degrees higher than you should.” The opposite is also true, as water boils at 212-degrees at sea level, but at 6200 ft, it boils at 200, this is the difference in pressure. While a higher-pressure cap will push the boiling point higher, the pressure inside the system can reach unsafe levels. Remember, the hoses, pump, and gaskets are under the same pressure and temperature, ballooning the hoses with higher pressures is a recipe for disaster.
Most radiators were downflow until the mid-60s, when OEMs began using crossflow designs, though many trucks kept the downflow design into the 1970s. A downflow design has tanks on the top and bottom of the radiator. Water flows from the pump to the top of the radiator, filling the tubes and flowing downward to the bottom tank, where it is pulled back into the engine.
The simple answer is absolutely not. There are so many different styles and types of engine radiators, it can get confusing, but there are a few styles that are the most common. Prior to the 1980s, pretty much every radiator was made from a copper-brass alloy, which offers the best heat transfer rate.
