LIQUID INTELLIGENCE WATERLESS COOLANT 1.5 LTR
This Amazing Dirt Bike Coolant Will Stop Overheating Dead In Its Tracks. Here’s Why…
Most dirt bike owners have found that it’s hard to keep their cooling system from boiling over when going slow on tight trails or in steep rough country. Our Liquid Intelligence 115 Waterless Motocross Coolant may help prevent that. This synthetic waterless coolant will double the thermal capacity of a dirt bikes cooling system and prevent overheating on demanding high torque low speed rides.
When dirt bikes are manufactured they come off the production line with a 50% solution of mono ethylene glycol based antifreeze anti-boil in their cooling system. A traditional glycol solution of this activity has a boil point of about 128°C to 132°C. In theory this level of anti-boil protection should be more than adequate to prevent any overheating issues. But as we all know it’s hard to keep a modern dirt bike from overheating, especially when riding at low speed with high torque in steep rough country.Most bikes will overheat and sometimes boil over under these kinds of riding conditions.
It wasn’t until we tested the boiling points of different glycol based coolant concentrations in a laboratory pressure vessel at 15psi that we fully understood the physics of heat dissipation in traditional coolants. What we found was that a coolants ability to dissipate and transfer heat within a cooling system is disrupted at a temperature much lower than its stated boiling point. We called this the vapour blanketing point.
We think that the vapour blanketing point has far more significance and importance to the performance of a coolant than a boiling point has. The vapour blanketing point of a coolant is the point at which it starts to fail…. whilst the boiling point of a coolant is when it has completely failed.
The vapour blanketing point of a 50% solution of mono ethylene glycol based coolant in a radiator using a 15psi pressure cap is between 93°C to 95°C. When a 50% active coolant reaches this temperature it starts to boil on the internal walls of the water jacket forming a layer of fine vapour. This insulating blanket of vapour reduces the efficiency of the entire cooling system to transfer heat from the block. When this happens, heat that it is still being generated in the block is not being dissipated and transferred through the cooling system as fast as it’s being made. So the cooling system temperature and the block temperature become out-of-sync with each other. The block temperature will continues to increase exponentially beyond its normal safe operating range. Once the engine is shut off and the coolant is no longer circulating through the radiator the greater block temperature transfers into the coolant. If the block temperature has exceeded the boiling point of the coolant it will boil over.
Most bike owners after a demanding ride have experienced boil over. Their coolant temperature would have gone beyond 140°C > for that to happen.
A dirt bikes normal running temperature is about 90°C. On hot days with low airflow on steep rough trails the engine temperature will always have the potential of reaching or exceeding the vapour blanketing point of about >93°C. A Conventional 50/50 glycol water coolant with a vapour blanketing point of between 93°C to 95°C does not always provide enough extra thermal capacity to prevent overheating under these types of riding conditions.
The Liquid Intelligence 115 Waterless Motocross Coolant has a boil point of 245°C and a vapour blanketing point of about 190°C which will double the thermal capacity of a dirt bikes cooling system. Under similar extreme riding conditions when the coolant temperature has exceeded 93°C our waterless coolant will not vapour blanket. It will continue to maintain contact with the internal walls of the water jacket, dissipating the heat and dumping it through the radiator efficiently… well after a conventional 50% coolant would have started to fail.
The main difference between using a conventional water glycol coolant and our Liquid Intelligence 115 Waterless Coolant in a dirt bike could be summarized this way:
A water glycol 50% coolant has less than half the thermal capacity of a waterless coolant and can allow for huge differences to develop between the block temperature and the radiator temperature. Whilst a waterless coolants greater thermal capacity ensures that the cooling system temperature and the block temperature remain in sync with each other… thus maintaining normal running temperature parameters in both the cooling system and the block even under demanding high torque low speed rides.
