How does the 70mm impeller affect cooling performance?

The 70mm impeller size determines how much coolant the pump can circulate per revolution. A properly sized impeller helps maintain the correct flow rate to the radiator and engine passages, supporting stable operating temperatures under load without overworking the water pump.

• 70mm impeller designed for factory-equivalent flow characteristics
• Balanced impeller profile reduces vibration and wear
• Materials chosen for corrosion and cavitation resistance
• Tested to ensure predictable coolant delivery under typical loads
