How to Flush Your Motorcycle Radiator

JJust like every other fluid on your motorcycle, your coolant needs to be changed periodically. At least every two years. Whats more, ist hat many trackday providers require that all the glycol be removed from your cooling system. We explain the differences in coolant, ethylene glycol, proplyene glycol and products with no glycol, then walk you step-by-step, through the process of flushing, cleaning and refilling the cooling system on your motorcycle.

The Products We Use

While Water Wetter by Redline is the most well known non-glycol coolant, we prefer Motul's MoCool. It's a non-glycol based radiator additive for use in racing/track applications where a glycol based product cannot be used. Engines run cooler up to 30°F (15°C). Improves thermal exchange and engine cooling system efficiency. For use in straight water or anti-freeze/water systems. Plus, it's legal in AMA, WERA, CCS, WRMMA and probably every other race club in North America.
