Description

The engine radiator and air conditioner condenser cooling system consists of two fans connected in parallel.

These are operated together at two different speeds by the same software.

• the first speed is activated at a first coolant temperature level or at a certain air conditioner coolant pressure.
• the second speed cuts in at a higher temperature or pressure threshold.

The fans are operated by means of three specific relays, one external and two located in the engine compartment junction unit. The fan supply line is protected by two specific fuses, located in the engine compartment unit.
