DESCRIPTION

The climate control system for models with T. Spark 16V engine is substantially the same as the one installed on the model with turbodiesel engine.

The main differences of this system are:

• the adoption of a minimum pressure switch.
• the adoption of a compressor with variable displacement which makes it possible to "follow" the load required by the system without engagement/disengagement of the compressor joint. In fact, the change in the flow rate of the coolant fluid in relation to the pressures involved makes it possible to compensate the change in the number of revolutions of the compressor (connected with engine rpm) to adapt the amount of "cold" produced according to the requirements of the system.
• a different position of the system components in the engine compartment.

NOTE: BELOW WE ARE GIVING THE DIFFERENCES OF THIS SYSTEM CONCERNING THE DESCRIPTIONS AND PROCEDURES COMPARED WITH THE TURBODIESEL MODEL.
