Engine Ice Hi-Peformance Coolant ✨ 

Engineer here. I have to give props to Engine Ice's Marketing department. They are very good at misleading people into believing they have a better performing coolant, and are making millions off pure marketing and consumer ignorance. The cooling performance increase of engine ice vs regular coolant is just due to it being ~60% water, 40% Propylene glycol (PG), where normal coolants are 50/50 Ethylene Glycol (EG)/water. Water is a better coolant than both PG and EG, and pretty much any other liquid. So with these coolants, the higher the water concentration, the better the coolant mixture. Engine Ice is just a watered down coolant. A 40/60 mix of EG/water would actually be slightly better than 40/60 PG/water (Engine Ice). The boiling point of these coolant mixtures is only a few degrees above just water. That 256F they advertise is not at atmospheric pressure, where water boils at 212F, but instead this 256F is under pressure of a radiator cap, likely around 1 barG. Straight water at that pressure would have a boiling point of 250F (@ 30 psia), so really not much difference there, Tricked you! Equal mixtures of EG would have a slightly lower freezing point than PG mixtures, making them slightly better; or you could say, for the same freezing point, you could have a slightly greater water concentration using EG, and a better coolant. The biggest difference between EG and PG is the viscosity, where PG is higher viscosity (thicker), taking more energy to pump through the system, and providing a lower heat transfer coefficient than equal EG mixes. EG is also a non-polar molecule, which makes it slippery and a good lubricant, where PG is polar and not slippery. This is one reason PG mixes like engine ice became popular as they are polar molecules like water. When EG (non-polar) spills on the track, it is a slippery hazard, where PG will not be so slippery. For spill safety, some tracks only allowed PG, (or pure water) so people began to associate PG coolants like Engine Ice with: race tracks, racing, and high performance, when really it was only about slippery spills on the track, not anything to do with performance of the coolant, which is actually lower for the same mixture ratios. As far as Deionized (DI) water, that makes zero difference vs distilled. I have DI water systems for power supply coolants, and you have to constantly de-ionize the water by flowing it through DI resin beds, else it becomes regular ionized water within minutes. So that De-ionized water becomes ionized in no time, which is actually good because DI is also very corrosive as it steals ions from the piping walls/radiator etc. So the marketing of DI water in Engine Ice being a better water than other waters is just BS, they tricked you again! The real benefits of PG coolants like Engine Ice are 1.) It is non-toxic. 2.) Spills on the track with PG are less slippery than EG. But in every other way, EG and PG and quite indistinguishable, with EG having a slight advantage in freezing point, and a clear advantage (besides price) in viscosity, meaning lower pumping power, and higher heat transfer coefficient. I use full strength automotive EG, and mix it with distilled water myself to achieve the desired freeze protection I need, where 40/60 EG/water gets down to -10F, and 40/60 PG/water (Engine Ice) would only be around -7F. At operating temp, the EG mixture would have about 15% lower viscosity than the PG mix. EG is the way to go unless you care about toxicity or spill slipperiness, don't get tricked by the Engine Ice marketing.

Mine is oil cooled ,so can't verify what i'm saying here. Instead of stock coolant ,try ready to use coolants,after flushing radiator with distilled water only(those who have heating issues) and do this in your presence ,so that the mechanic wont add water in the coolant. If the ready to use coolants get diluted,the character is lost and it becomes ordinary water

Does it work well for you ? I have a rc390 and I have tried it a couple of years ago. And it was worse the stock. The bike was overheating and shutting down. I got it checked 2 times. No air and the system was properly cleaned but still I faced this issue.

Not work
