Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Refrigerant Capacities
The capacity of the refrigerant R1234yf can be found in the vehicle-specific repair information. Refer to REFRIGERANT R1234YF CAPACITIES .
When charging the high-pressure side of refrigerant circuits, always use maximum amount of refrigerant (some of the refrigerant remains in the charging hoses).
Make sure the A/C service station is on the same level as the vehicle (maximum difference 50 cm) when charging the refrigerant circuit. If a difference in height is too large, a difference between the amount of refrigerant displayed on the service station and the actual amount filled in the circuit may result (depending on the version of the A/C service station). The filling precision of the A/C service station may change.
