Auxiliary water pump for all NCV3 Sprinter vans, including the V6 3.0L and I4 2.1L models.
This pump pushes coolant through the heater core and typically runs whenever the ignition is on. The pump is most important when idling when coolant flow from the water pump is low. A failed pump can result in weak or no interior cabin heat.
