To find the precise amount, you must consult your vehicle's owner's manual. The capacity will be listed in the section dealing with air conditioning maintenance or specifications. Alternatively, you can look for a sticker under the hood, often near the radiator or on the HVAC components themselves. This sticker may specify the refrigerant capacity.
Without that information, providing a number would be inaccurate and potentially lead to overcharging or undercharging your system, which can damage your AC compressor.
