Dual Solenoid Coolant Heater Control Valve

This dual-solenoid coolant heater control valve acts as the core electronic component for BMW air conditioning heating systems and directly replaces OEM parts 64219310349 and 64119119164. Two independent solenoid actuators integrate into one valve body and control cold and hot coolant circulation at the same time. The unit perfectly fits multiple BMW chassis models including E60, E66, F02, F18, X5 and X6. Original vehicle pipelines and wiring plugs match the valve dimension precisely and require no drilling or cutting modifications during installation.

Glass fiber reinforced engineering plastic forms the valve housing and resists corrosion from high-temperature antifreeze. Fluororubber internal seals eliminate coolant leakage and dripping issues. Heat-resistant insulated solenoid coils receive stable signals from vehicle ECU and avoid spool sticking or temperature control failure in cold weather. Separate dual valves adjust water flow independently and deliver steady outlet air temperature without fluctuating heat or weak heating during cold-warm mode switch.

Every finished unit passes full hydraulic pressure and electrical continuity tests before shipment. We copy original factory assembly standards to extend service life. The complete set includes original positioning brackets and standard pipe connectors, and technicians finish damage-free replacement of old valves within ten minutes. This valve fully fixes common heater faults such as temperature imbalance, no warm air and pipeline leakage, and delivers consistent cabin temperature control for long-term driving.
