These add in cooling products are a marketing ploy that makes the manufacturers a lot of money and do not do anything to cool your engine.
Every element on this planet, both liquid and solid has a boiling point. It just takes the right amount of heat to turn the liquid and solids into a gas. I will leave solids out of this as no one puts solids in a radiator.
The bubbles you see when the liquid boils are part of the elements that make up the liquid, which boil at the lowest temperature, turning into a gas and separating from the remaining element/s of the liquid. The remaining element/s would eventually turn to gas also if the correct temperature is reached.
Our common fresh water will boil at 100 degrees C at a pressure of approximately 14.7 psi. Which is the pressure considered to be at sea level.
If you reduce, the pressure by moving higher than sea level the water will boil at lower temperatures. So if you ride your bike say 1500 meters higher than sea level your water will boil at about 95 degrees C.
The coolant you add to your radiator will increase the boiling point for the mixture somewhere between 110 to 120 degrees c dependant on the mixed ratio you use, as it has a higher boiling point than pure water.
You can even make those boiling point temperatures higher by creating more pressure in your radiator against the gases by sealing the system with a radiator cap that has a higher-pressure rating than 14.7 psi. However, this doesn’t cool the fluid in your radiator. It just stops it from boiling at that pressure and the temperature of the fluid goes up to whatever the radiator cap relief valve will allow the fluid to boil at. Therefore, that higher fluid temperature is less able to take the heat away from the metal components of your engine as the fluid is already very close to its boiling point and cannot absorb any more heat.
This means every component of your engine is subjected to this heat and heat will eventually destroy the motor.
Nothing changes the fact that the temperature of the coolant mixture, pure water or using the “ICE” type additives reaches a certain level due to the heat produced by the motor and the temperature of the air that is passing through the radiator and around the engine casings and is not controlled by the composition of the liquid.
The fluid circulating through the motor absorbs the heat and the fluid then carries that heat around until the fluid is cooled by some means.
The additives that make up the liquid in the cooling system have no way to remove the heat. They just carry the heat around until it is cooled.
That job is taken care of by the size of the radiator and the temperature of the outside air.
Therefore, the only way to make and engine run cooler is for cool air to pass through the radiator and around the engine casings.
The first thing you do to a high performance motor cycle racing engine is to fit a larger radiator.
You may have noticed in MotoGP that when they run the bikes in a hot country they remove the front mudguard and any other obstructions to the airflow. Conversely, when they run the bikes in a cold country they tape over some parts of the radiator.
These bikes never use anything but distilled water in the radiators. No additives are ever used.
