This valve uses a single inlet and single outlet, both measuring 18 mm outside diameter, and features a female connector for the electrical interface. The plastic/stainless steel design supports the demands of coolant control service while matching the original equipment layout for the listed BMW Z3 fitment.

What It Helps Solve

• No cabin heat or inconsistent heater output
• Temperature control that stays stuck hot or cold
• Coolant flow issues through the heater core
• Faulty electric heater valve operation on BMW Z3 models
• HVAC performance problems tied to worn coolant control components

Installation Notes and Tips
