When combustion engines operate, they generate heat and there is liquid coolant circulating to keep it cool. Once the engine is heated, the thermostat opens and coolant is pushed from the engine’s hottest parts to the radiator to be cooled before returning to the engine. With cylinder and head internal operation temperatures in the hundreds of degrees, The boiling point of simple water can be swiftly exceeded by the liquid water and coolant combination. The pressurized radiator cap also aids in making it less likely to boil over.

How do i know it’s time to change the coolant

For recommended coolant replacement intervals, consult your bike owner’s handbook for the recommended service interval. Some motorcycles require replacement every few years.

If you don’t know when the coolant was last replaced and your motorcycle is more than four years old, change it immediately. Flushing is part of the cooling system servicing (draining, filling with water, and emptying again), but if you change it often, flushing is unnecessary.

When emptying the system to change the coolant, always inspect the radiator and heater hoses and replace any that are old, broken, or swollen.

Why is it important to change your coolant

The antifreeze/coolant in the engine keeps everything cool and, unlike water, will not freeze if you leave the automobile parked outside in the winter. Coolant is more resistant to both boiling and freezing, and it prevents interior corrosion. The antifreeze ingredients in the coolant degrade with time, especially if you fill off the coolant with water on a frequent basis. This might cause harm if the coolant freezes and expands in cold conditions.

The cooling system should be emptied, cleansed, and refilled on a regular basis to replenish the antifreeze mixture and avoid the formation of rust and corrosion, which can impede cooling system efficiency and cause engine damage. The lubricating ingredients in the coolant for the water pump and thermostat must also be supplied on a regular basis.
