Alfa Romeo GT Bertone Heating and Ventilation Spare Parts

The heating and ventilation of the Alfa Romeo GT Bertone supplies the closed coupé interior with warmth and fresh air and keeps the windows clear in cool or damp weather. As the Bertone is a closed body with a larger air volume and its own ventilation paths, the air distribution differs from that of the open Spider. As a manufacturer, supplier and spare parts specialist for classic Alfa Romeo parts, we carry the heating and ventilation components for all versions of the Bertone coupé. The correct assignment to the series and the engine is important, as above all the air duct hoses and the routing differ depending on the version. Ordering by the Bertone name alone easily leads to unsuitable parts and avoidable returns, whereas stating series, year and engine allows a reliable selection. The following overview shows how the product groups relate. Since the coupé was built over more than a decade in several engine versions, different development stages also meet in the heating and ventilation, which show in valve, heater core and air routing and demand careful selection.

Model and series reference

On the GT Bertone the heating is offered in a first and a second series. The first series uses a metal heater valve with two hose stubs and a matching heater core, the second series a plastic valve with a changed connection and a heater core tuned to it. The changeover concerned above all the connections and the routing of the hoses, so that parts of the two series do not readily fit one another. This division concerns the early Sprint GT and the 1300 to 1600 versions as well as the 1750 GTV and the later 2000 GTV, so the series should be known before selection. With the air distribution it should be added that the 2000 GTV and the Junior Unificato have their own air duct hoses, which differ from the earlier 1300 to 1750 models. Anyone who knows the series, year and engine of their Bertone and whether a metal or plastic valve is fitted can compile valve, heater core, blower, hoses and control precisely and without wrong orders. As valve and heater core match each other depending on the series, they should always be regarded as a coherent unit.

Shared across the range or model dependent

The Bertone shares several heating parts with the Giulia, such as the heater blower motor, the seal of the heater box and individual control parts. Here the centre console plays a role, as the bezel and fixing depend on it. Coupé-specific, however, are the air duct hoses to the dashboard, which are offered in their own lengths depending on the engine, as well as the side air hose to the dashboard vent. It would be wrong to assume that the whole system is identical between Spider, GT Bertone and Giulia. Commonalities exist with blower, valve and seal, but the air routing in the interior follows the closed coupé shape. Anyone wishing to use parts from a Spider or saloon stock should therefore check carefully whether the air duct hoses and the routing suit the coupé version, since the ventilation in particular is tied to the closed body. The blower motor, valve and seal can indeed be shared with the Giulia, but the air duct hoses and their routing follow the coupé shape and the respective engine.

Part types and product groups

The range for heating and ventilation is divided into several groups. These include the heater box with seal, the heater core in the first or second series version, the heater valve and the heater blower motor. Added to this are the cooling water hoses between valve, intake manifold and water pump, the heater controls with knob and bezel, the air duct hoses for centre and side, the air vent cover as well as the related seals and fixings. There are also small parts such as screws for the bezel and control levers, which are easily overlooked during a repair but are important for a clean function. The control knobs in a black or chrome-plated version also belong here and depend on the year and the centre console. These groups represent the path from the heat source to the air distribution in the coupé and can be selected by series and engine, so that a step-by-step repair of the system remains easy to plan and individual components can be renewed one after another. As the Bertone, being a closed coupé, has a larger air volume and longer ventilation paths, an effective air distribution and a reliable heating are particularly important.

Differences by year, series or version

The most important difference lies between first and second series at the heater valve and the heater core. With the air distribution the centre air duct hose of the early 1300 to 1750 models differs from that of the 2000 GTV and the Junior Unificato, which has its own length. The side air duct hose to the dashboard vent is also Bertone-specific. With the control parts it must be noted whether the vehicle has a centre console, as bezel and fixing depend on that. Anyone ordering parts should therefore state series, engine and the presence of a centre console so that valve, heater core, hoses and control match. Even with apparently similar parts a close look is worthwhile, because small differences in length, connection and fixing decide whether a part fits without adaptation and the system is in the end tight and reliable. Anyone overhauling the heating should therefore choose the coherent parts of one series rather than mixing components of different versions.

Notes on selection

For a reliable selection it is advisable to determine the series and the exact version of the Bertone before ordering and to check the existing heater valve for metal or plastic. A photo of the valve, the hose connections and the air vents eases the assignment and avoids queries. With the 2000 GTV and the Junior Unificato the own air duct hoses should be noted, as the centre hose has a different length than on the earlier models. Seals for the heater box should be ordered at the same time, as they are needed in several places and ensure a tight ventilation. Anyone fully overhauling the system should plan valve, heater core, blower, hoses and seals together from the start and select them to match the series and the engine. As a manufacturer and spare parts specialist we advise on the correct assignment and supply original parts as well as high-quality reproductions, so that even older systems can be fully restored. If there is uncertainty about the series, the engine or the control, it makes sense to check briefly before ordering, so that the right parts are chosen from the start and unnecessary repeat orders are avoided.

Frequently asked questions

How do first and second series differ?
The first series uses a metal valve with two hose stubs, the second a plastic valve with a changed connection, each with its own matching heater core and routing.

Are the air duct hoses the same for all engines?
No. The centre air duct hose differs between 1300 to 1750 and the 2000 GTV or Junior Unificato, and the side hose is also Bertone-specific.

Does the blower motor also fit a Giulia?
The heater blower motor is offered for Giulia and GT Bertone, there are clear commonalities here, as with valve and seal.

Does the centre console matter?
Yes. Bezel and fixing of the heater controls depend on whether the vehicle has a centre console.

What details do I need for a reliable order?
Series, year, engine, valve type and the question of the centre console, if needed supported by a photo of the valve and the air vents.

Do you offer reproductions?
Yes. Alongside original parts we carry high-quality reproductions, such as valves, hoses, bezels and seals.
