Top Up of R134a Refrigerant: 

• 1. You need some tools, like a digital manifold gauge set, can of r134a, can tap, digital thermometer, r134a adapter

• 2. Using a thick solution of dish washing liquid and water to figure out whether leak-free

• 3. With the can tap connected to the can of r134a hose, turn on the can tap valve a little to get the air purged out, and then turn off the blue valve on the manifold

• 4. With the car started and AC compressor on, recirculation mode, blower fan on max, slowly opened the blue valve to allow r134a into the system. Keep an eye on the low-pressure gauge. Patience is needed here to add r134a and let the system equalize then add some more
