Aisin has developed the electric water pump for engine cooling as a pioneer in Japan. It has been necessary to downsize the pump and reduce cost to install the electronically controlled components into the engine. But Aisin has accomplished it with sufficient reliability for engine installation by developing various ways as follows.
