Specific features of the heating and ventilation system on the Mehari
Unlike the 2CV, whose heating system has undergone a number of changes over the years, including the evolution of its heating tubes, the heating system on the Méhari has remained unchanged.
While the Citroën Méhari was fitted with a single 602 cm3 twin-cylinder engine throughout its production run between 1968 and 1987, the 2CV went through 3 generations of engines, going from 425 cm3 to 435, then to 602 cm3, which in turn led to changes in the heating system.
The design of the heating circuit in the Mehari differs slightly from that of the 2CV. The hot air from the engine is channelled in 3 separate directions through special heating tubes: the front wings, the passenger compartment and the windscreen. The Mehari also has 2 additional fresh air tubes running from the radiator grille to the dashboard air vents. The flow of fresh air is provided by the cooling fan positioned in front of the radiator, providing ventilation on board the vehicle.

The various components of your Mehari's heating and ventilation system
Our online shop gives you access to the full range of 2CV Méhari Club Cassis products for the Méhari heating and ventilation system, including our best-sellers at attractive prices, such as the Méhari heater tube set. This kit includes all the different types of tubes required for the system to work properly. It consists of 2 long tubes (1140 mm long) to ventilate the passenger compartment, 2 short tubes (165 mm long) to evacuate hot air to the outside at the front wings, and 2 side tubes (left and right) to supply hot air to the interior of the vehicle via the heat exchangers. Note that each of these tubes can be purchased separately.
Also on sale: our two exchanger references (left and right). Positioned at the level of the exhaust pipes on each side of the engine, they are operated by cables connected to the heating control and allow the hot air flow to be directed either towards the outside at wing level, or towards the passenger compartment via the long tubes. These converge on the heater control unit, which regulates the warm air to the air vent at the bottom of the windscreen, at the top of the dashboard, or at foot level.
Various accessories are also available, including heat exchanger foam seals, heater tube rubber seals and air inlets. A range of heating controls for regulating the flow of cool or warm air are also available, including heater control levers, dashboard side air vent outlets, control cables and various brackets for attaching these components.
How do you check the heating and ventilation system in your Mehari?
If there is a fault (reduced performance, strong exhaust or engine smell in the passenger compartment, etc.), don't hesitate to visit one of our partner garages or to carry out your own diagnosis. These malfunctions may be linked, for example, to a loss of efficiency of the heat exchanger foams present in each heat exchanger, or to the puncturing of one or more
heater tubes in the circuit. In both cases, the defective parts will need to be replaced.
