How do you change the refrigerant in a Porsche Cayenne?
Luckily, replacing and topping off refrigerant is a relatively easy process. Begin by starting the car, turn on the A/C system and fan to full blast, and let the car run for about three minutes. Following the instructions included with the kit, connect a new can of refrigerant to the hose/gauge assembly.
