How to Clean an ATV Radiator

A clogged ATV radiator can cause the engine to overheat, creating damage to other engine components. Four-wheelers are often exposed to weeds, brush, mud, water and other debris in far greater amounts than other off-road vehicles, so they are more prone to developing a clogged radiator. If you lack mechanical ability, cleaning an ATV radiator is likely best left to a professional, but if you are handy with a wrench, you can clean your four-wheeler radiator yourself.
