Evans Waterless Engine Coolant has time and time again proven to be an unbeatable coolant choice on and off the track, with many success stories from teams using Evans.  Some of the most striking comparisons between Evans Waterless Coolant and standard water-based coolant can be seen in the American Flat Track Series. Even though flat track bikes don’t get mud clogging up the airflow to their radiators like in off-road racing, they build a lot of heat from wide open throttle on the track. The trouble comes if there’s a crash and they stop the race to clear the track.

Afterboil happens when a hot engine is turned off. The pump stops moving coolant and the fluid that is sitting in the engine boils; this happens even if there is a radiator fan cooling the radiators down. Water expands over 1,200 times in volume when it converts to vapor so boiling within the engine will push vapor and liquid out of the vent. The vent has a small opening that can’t relieve the pressure as fast as it is built in the system so the system pressure can go well above the limit set by the radiator cap. This is when a hose can blow off.

At a recent flat track race in Georgia, USA, there was a great battle between Jared Mees on the #9 Indian factory bike and Sammy Halbert on the #69 air cooled Harley. The dogfight ended when they clipped each other and Sammy hit the ground on the front straight bringing out the red flag. All the bikes were sent to an impound area in the infield to await the restart. The rule is that if a bike has a mechanical issue that delays the restart, it must go to the back of the grid; this becomes a race to see who will be the first to overheat.

Jared, a long time user of Evans Coolant, wasn’t worried about his bike, but the riders using water or conventional coolant were all at risk. Many bikes boiled over, delaying the race. It was good to hear the announcer saying that they should be using Evans!

Although most teams are very mechanically competent, these types cooling system failures are no fault of the team, rather the failure of the coolant being used. 

Evans Waterless Engine Coolant does not boil until over 190 degrees C virtually eliminating any chance of overheating in the radiator. This high boiling point is responsible for a drastic drop in the metal surface temperature. This benefit is apparent not only when the engine is running but also during heat soak. This is defined as the period when a hot engine is shut off and since there is no liquid movement through the radiator the critical components rise in temperature. Due to the Evans product refraining from boiling more heat transfer occurs.
