How much refrigerant does a Chevrolet G Series Fullsize Van / Express A/C system hold?

The 2013 Chevrolet G Series Fullsize Van / Express (8 Cyl. 4.8 Eng.; w/ Rear AC) holds 56.44 oz of R-134a as a complete system charge. That is the amount for an empty, evacuated system, not for a top-off.

Can I put R-134a in a car that uses R-1234yf?

No. The two use different service fittings on purpose and different oils. Charging the wrong refrigerant can damage the compressor and is illegal in the US under EPA rules.

Can I recharge the A/C myself?

A DIY can with a gauge can top off a slightly low R-134a system. If the system is empty it has a leak, and adding refrigerant without fixing it wastes the can. A full charge needs the system evacuated and weighed in, which is a shop job.
