Coolant shut‐off valve
| | |  | NOTE: - 1. Coolant shut‐off valve
- 2. Solenoid valve
- 3. Vacuum pump
- 4. Brake servo connection
- 5. Connection to exhaust gas recirculation system (EGR system)
- On vehicles with air conditioning, the supply of coolant to the heater radiator is cut off by means of the coolant shut‐off valve when the air conditioning is in operation.
- The system operates by vacuum which passes to the coolant shut‐off valve by means of a solenoid valve. The vacuum is taken from the line to the brake servo.
- The solenoid valve is controlled by the EPIC control module.
