|WINNER: Small water pump helps engines warm up swiftly
What: Electro-hydraulic controlled flow water pump
Innovation: The pump restricts coolant flow on cold starts so the engine warms up faster, reducing emissions and boosting fuel economy. A small hydraulic piston inside the pump regulates coolant flow, enabling a 40 percent reduction in pump size.
