Expert Pro-Tip: With these Polaris 900 engines, always pay attention to your cooling system during a rebuild. A failing water pump impeller or clogged radiator can cause heat spikes that will ruin your new top-end quickly. Since this kit includes a water pump rebuild component, make sure you take the extra time to flush your radiator and cooling passages thoroughly before firing the engine for the first time.
