Brand Denso
Vacuum Solenoid Assembly for the heater control system on V8 petrol models.

This electrically operated solenoid valve controls the vacuum supply to the heater and ventilation control actuators. When energised by the heater control switch, it opens the vacuum circuit that operates the air blend and distribution flaps inside the HVAC housing, directing warm or ambient air to the selected vents. A faulty solenoid typically results in loss of heater function or fixed vent positions regardless of the control setting.

Frequently asked questions

What does the vacuum solenoid assembly do?
The vacuum solenoid assembly is an electrically operated valve that controls the vacuum supply to the heater and ventilation actuators on Land Rover V8 petrol models. When the heater control switch energises it, it opens the vacuum circuit that moves the air blend and distribution flaps inside the HVAC housing.
What are the symptoms of a faulty vacuum solenoid?
A faulty vacuum solenoid typically causes loss of heater function or vents stuck in one position regardless of the control setting. Because it drives the vacuum to the blend and distribution flaps, a failure leaves the HVAC unable to switch air between vents or change temperature.
Which models does this Denso vacuum solenoid fit?
This Denso solenoid fits the Discovery 1 (to VIN MA081992) and Range Rover Classic 1992-1994 (to VIN MA647645) with V8 petrol. Both applications have a VIN cut-off, so check your chassis number against the fitment notes before ordering.
