TPR010W Full Flow Water Kit for Billet Valve Cover (Polaris RZR)

Protect your engine and improve cooling efficiency with the TPR010W Full Flow Water Kit, designed specifically for use with the TPR010 billet valve cover. This system addresses one of the most common causes of engine failure—air pockets in the cylinder head water jacket, which are responsible for up to 80% of head gasket failures.

This kit creates a constant flow of coolant through the highest point of the cylinder head, eliminating trapped air or steam and ensuring consistent cooling performance. By routing coolant through the top of the water galley, this system helps maintain proper temperatures and significantly improves engine reliability in high-performance applications.

It easily integrates into your system by plumbing into the radiator return hose at the thermostat housing, giving you a convenient and effective way to bleed coolant from the rear of the vehicle.
