Vertex Gaskets 21-23 Gas-Gas EX450F Water Pump Rebuild Kit

This water pump rebuild kit from Vertex Pistons uses a high-quality mechanical seal, a critical component for preventing leaks and ensuring your cooling system runs efficiently. It's designed to get your Gas-Gas EX450F's water pump back in top shape, addressing common wear points that can lead to coolant loss or overheating.

Inside this kit, you'll find everything needed for a thorough overhaul: all the necessary gaskets to seal the housing properly, o-rings for dynamic sealing points, the mechanical seal itself, oil seals to protect bearings, and the bearings that allow the pump shaft to spin smoothly. This makes it a straightforward way to repair your existing water pump instead of replacing the entire unit, offering a cost-effective solution.

When you're rebuilding the water pump, pay close attention to the cleanliness of the mating surfaces for the gaskets and seals. This kit is a direct replacement for your original equipment, meaning it's made to fit right and function as the factory part did, but at a much better price point.
