Cooling System

A personal watercraft's cooling system works by passing liquid, either buy coolant (closed-loop system) or draws from the water it rides on (open-loop system), that continuously passes through the engine block. Powered by a water pump, the liquid is pushed through the engine block channels, absorbing heat from the engine. PWC Fanatics has a variety of cooling system components for all your Sea-Doo, Yamaha WaveRunner & Kawasaki Jetski needs!
