Heating and ventilation components for classic British cars, covering heater matrices, heater boxes, heater valves, blower motors, heater cables, demister components and ventilation controls. Cabin heating on British classics from this period is typically a hot-water system drawing coolant from the engine through a heater matrix, with a small electric blower fan providing forced airflow and demister vents directing warm air to the windscreen.
Heater Matrices
The heater matrix is a small radiator-style heat exchanger mounted within the heater box, with engine coolant passing through it and cabin air drawn across it by the blower fan. Matrices are typically copper-brass construction in original specification, with aluminium-core replacements available for some applications. Failed matrices are a common cause of coolant loss inside the cabin and a heater that fails to warm the car, a leaking matrix should be replaced rather than repaired.
Heater Valves and Cables
Heater valves control the flow of coolant to the heater matrix and are typically operated by a Bowden cable from a dashboard control. Original Smiths heater valves are well-supported across the British classic range, with reconditioned and new replacements stocked. Heater cables are stocked in original lengths and operating configurations.
Blower Motors
Cabin blower motors are typically small DC motors mounted within or alongside the heater box. Original Lucas and Smiths motors are stocked across the major applications, with replacement brushes and complete units available depending on the level of repair required. Blower fan resistors that control speed settings are also stocked.
Demister and Vent Components
Demister vents, demister hoses, vent grilles and ventilation control flaps are stocked across the major applications. Original-pattern demister hoses in the correct diameters and lengths are commonly required as part of restoration work, where the original hoses have hardened or split. The MGOC Spares British Classic Car Parts Heating & Ventilation range encompasses heater matrices, heater boxes, heater valves, blower motors, heater cables, demister components, vent grilles and ventilation hardware for the British classics we serve. MGOC Spares is constantly expanding our range for these non-MG British classic marques, and new lines are being added to this section regularly.
