Motorcycle coolant should be changed at least every two years because its performance deteriorates over time. When a bike is purchased that has an unknown or questionable service history we always recommend changing it to have a known basis. Aluminum corrosion or changes in the fluid-to-coolant ratio are the usual causes for this. The solution should be kept as alkaline as possible, which is why most coolants include specific ingredients to help achieve this. However, these become less effective over time.

Ensure you choose a coolant made for aluminum alloys, since all motorcycle engines are made of these. Most bikes have a coolant capacity of about one gallon, although this can vary. Most coolants are pre-mixed and ready to add, we recommend Engine Ice for all bikes.
