Despite our evolution towards Cooling Systems with more electronic control, at Cojali Parts we remain committed to our beginnings by manufacturing more than 150 references of aluminium fans for older commercial vehicles from Pegaso, Renault, Mercedes, DAF, Iveco, MAN and Volvo brands.

The electrical connection between a vehicle and the electromagnetic viscous clutch of its cooling system takes place through a connector, in which some pins are assembled. These pins enable the transmission of the electric signal emitted by the control unit.

There are several components involved in the assembly process of a viscous clutch. These components can be obtained through different manufacturing processes depending on the geometry and properties of the materials they are made of.

Currently, it is necessary for new commercial vehicles to meet the Euro VI standards, which deal with restrictions regarding fuel consumption. For this reason, all vehicle components that affect fuel consumption directly must achieve a performance as optimal as possible. These components include the fan clutch of the cooling system.

One of the most important parts of a cooling viscous clutch is the main shaft. The rest of parts are assembled upon this component, which is in charge of transferring the movement of the engine to the clutch and bearing its weight. For that reason, the main shaft is the component more prone to mechanical failures or breaks.

When we are at the final development stages of a new viscous clutch model, it is essential to carry out performance tests in the vehicle itself in order to verify that the clutch behaviour meets the cooling needs of the vehicle under real conditions.
