Connect the special device for collecting the coolant to the port located on the compressor intake pipe, that can be accessed from the left rear wheel arch compartment.
Drain the system slowly to prevent the formation of ice inside the expansion valve and oil leakage from the
compressor.
After draining the system completely, bleed the air from the coolant charging cylinder and system.
A vacuum of approximately 0.5 ÷ 0.6 bars in the system is required according to the device used.Check system tightness for at least 15 minutes after eliminating all the air from the system. , I W K H V \ V W H P L V Q R W D L U W L J K W ¿ O O Z L W K D S S U R [ L P D W H O \ J U D P V R I F R R O D Q W D Q G O R F D W H W K H O H D N

•Disconnect the ground cable from the battery negative terminal before removing electronic components (carry out the operation on the battery disconnect inside the engine);
• electrical measurements on electronic components must be carried out only with adequate measuring equipment;
• make sure that electronic device cables (length, type of conductor, positioning, clamping, shielding continuity
where required, grounding, etc.) are correct for the system and that have been carefully restored to the original condition after service;
• never insert or remove the connector from the electronic control units while powered;
• in case of temperatures over 80°C (drying ovens) remove the electronic control units;
• when making connections, tighten the connector nuts (temperature, pressure sensors etc.) to the prescribed
torque ;
• electronic control unit measuring at plugs, plug connections and electrical connections of components are to be
carried out only using the appropriate equipment; never use improper tools such as metal wires, screwdrivers,
clips or suchlike; besides the danger of short circuits, these methods could damage the plug connections and subsequently cause contact problems.
