Electric Water Pump

Electric Water Pump

Overall Description:

Electrically driven Water Pump that operates on demand. The Electric Water Pump is not dependent on the engine as the ECU will activate the electric water pump and vary the pump speed and coolant flow rate based on the engine cooling needs. This minimizes the load on the engine which reduces fuel consumption and pollution.

AISIN Water Pumps provide optimal cooling without creating excess load to the engine. AISIN’s advanced aluminium die-casting technology allows for size and weight reductions without sacrificing cooling performance. The highest quality materials are used, creating stronger body design and resistance to corrosion. Advanced technological design produces smooth coolant flow channels, efficient rotors, ball bearings, and carbon ceramic mechanical sealing for optimum cooling performance and longevity.

Premium quality, ethylene glycol based antifreeze coolant concentrate, designed primarily to meet the stringent corrosion protection requirements of late model car engines which have a significant amount of aluminum their construction. With the anti-rust performance, AISIN Long Life Coolant is suits for the Aluminum Water Pump and to all material used cooling line of engine including Aluminum radiator. 

AISIN Super Long Life Coolant has an extended drain interval. It is recommended to replace the coolant after 4 years or 100,000 kilometers, which is double the interval or regular coolant in Japan. The demonstrates the AISIN Super Long Life Coolant’s durability and reliability in providing long-term protection for the engine.
