A/C refrigerant by vehicle: R-134a or R-1234yf, from the owner’s manual

By Car Spec Sheet · Updated Oct 18, 2026 · Every example is checked against the owner's manual page it links to. How we work

Which refrigerant each vehicle’s air conditioning uses, from the 8 manuals on this site that name it. Each entry links to the vehicle’s refrigerant page, which gives the charge amount where the manual prints it.

R-1234yf and R-134a systems are not interchangeable: the service fittings differ on purpose. A/C work involving refrigerant should be done by a certified technician.
