Product Overview

The coolant water pump, OEM number 2742001407, is an electrically driven pump that circulates coolant through the engine, independent of engine speed. It runs whenever the cooling system calls for flow, including when the engine is off or idling, so its motor and seals work under near-constant duty, which makes it a regular replacement item in the engine cooling category.

A failing electric water pump can cause poor coolant circulation and engine overheating, so a reliable, precisely made replacement matters. GSK Auto manufactures this water pump to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm the OEM number match before shipping.

What Is a Coolant Water Pump?

Function: The coolant water pump circulates coolant through the engine block, cylinder head, and radiator, carrying heat away from the engine to keep it within its safe operating temperature.

Working Principle: Unlike a traditional belt-driven pump, this electric water pump uses its own motor to turn the impeller, so the engine control unit can run it at variable speeds or even when the engine is stopped. This allows coolant flow to be matched precisely to cooling demand, including after shutdown to manage residual heat.

Importance: Reliable coolant circulation is essential to prevent localized overheating and to protect the engine under all operating conditions, including idling and stop-start cycles. A failing pump can lead to overheating and potential engine damage.

Common Failures & Signs: Engine overheating, including at idle. Coolant leak from the pump housing or seal. Whining, grinding, or humming noise from the pump. Coolant warning light or high temperature gauge reading. Reduced heater output from the cabin. Pump not running when checked electrically.
