Does a Chevy Venture require more than one can of R134 refrigerant to recharge if it is empty due the motor having been taken out and replaced after repairs?

A Chevy Venture's AC system capacity is typically around 2-2.5 pounds of R-134a refrigerant. One 12-ounce can of R-134a is roughly 0.8 pounds. Therefore, yes, it will almost certainly require more than one can to fully recharge if the system is completely empty. You'll likely need at least three cans, possibly more, depending on any leaks that may have occurred during the engine removal/replacement process.

It's also crucial to remember that simply adding refrigerant isn't the right approach. A proper recharge involves:

* Vacuuming the system: This removes air and moisture which can damage the compressor.

* Checking for leaks: A leak detection is crucial to ensure the refrigerant doesn't escape immediately.

* Adding the correct amount of refrigerant and oil: The system needs the proper amount of PAG oil to lubricate the compressor.

Attempting to just add refrigerant without these steps will likely damage the compressor and be a waste of refrigerant. It's best to take your Venture to a qualified AC technician to have the system properly evacuated, inspected, and recharged.
