Heater Control Water Valve for BMW

The heater control water valve controls coolant flow into the cabin heater core, letting the climate system regulate cabin temperature on BMW models such as the 528i, 535i, 550i, 640i, 650i, 740i, 740Li, 760i, and 3L applications.

Overview

This heater control water valve manages the flow of hot coolant to the heater core so the cabin warms up as commanded and shuts off when it is not needed. It fits BMW 528i, 535i, 550i, 640i, 650i, 740i, 740Li, 760i, and 3L models, replacing a failed valve that causes no heat, constant heat, or coolant loss. It is intended for owners and technicians servicing the cooling and climate system on these BMW vehicles.
