Description

The engine radiator and air conditioner condenser cooling system consists of two fans activated at two different speeds.

• 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 operation of the two fans is simultaneous with the ''series/parallel'' mode: supplied in series, both fans turn at a first speed; supplied, on the other hand, in parallel, they rotate at top speed.This particular operationis managed by means of a remote control switch located directly on the radiator next to the two fans.The two fans are operated by means of two specific relays located in the engine compartment junction unit. The fan supply line is protected by two specific fuses, located in the engine compartment unit.
