Where do you put the r134a refrigerant in your 2007 Chevy Impala?

To add R134a refrigerant to your 2007 Chevy Impala, locate the low-pressure service port, which is typically found on the larger diameter aluminum line running to the evaporator. Remove the service port cap and attach the refrigerant hose from your can of R134a, ensuring it's securely connected. With the vehicle running and the AC on, follow the instructions on the refrigerant can to add the correct amount of refrigerant. Always check for leaks before concluding the refill process.
