Where is the A/C low-pressure A/C recharge port located?

The low-pressure A/C recharge port on a 2017 Fiat 500L is located on the A/C line that runs from the A/C compressor to the condenser which can run inside the fender well. The port is located on the line that runs along the driver's side of the engine compartment.

To access the low-pressure A/C recharge port, you will need to open the hood of your car and locate the A/C lines. The low-pressure line is the larger of the two lines and will have a blue or black cap on the port. The high-pressure line is the smaller of the two lines and will have a red or black cap on the port.

When adding refrigerant to your A/C system, it's important to use the correct type and amount of refrigerant as specified in your owner's manual. Overcharging or undercharging the system can lead to poor cooling performance or damage to the A/C components.

Hello,

On the Fiat 500 the high-pressure port is located next to the coolant expansion bottle. see image 1
The low-pressure port is located on top of the AC compressor.
To access this port, you will need to remove the air filter housing.
It is located at the rear of the engine, passenger side, covered with a grey cap. see image 2
