What kind of coolant is used for dirt bikes?
Several types of coolants can be used in dirt bike engines, including water, ethylene glycol mixtures and propylene glycol mixtures. An effective coolant protects the dirt bike by transferring heat away from the engine block, lubricating the water pump and seals and inhibiting corrosion.WaterFor recreational dirt biking in a temperate climate, water is an adequate engine coolant. De-ionized water or water treated with special additives is necessary to prevent corrosion. Water will not protect the engine at temperatures below 32 degrees F. or above 212 degrees F. (at sea level), so better coolants are required for engine protection under extreme temperature conditions.Ethylene GlycolCoolants made with a mixture of ethylene glycol and water offer engine protection under more extreme conditions than water alone provides. A 50/50 ethylene glycol to water mixture has a freezing point of -36 degrees F. and a boiling point of 225 degrees F.Propylene GlycolPropylene glycol-based coolants are s
