How much refrigerant does a Dodge Caravan / Grand Caravan A/C system hold?

The 2014 to 2018 Dodge Caravan / Grand Caravan (6 Cyl. 3.6 Eng.) holds 28.96 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.
