How to refill air conditioner

Preparing to Add Refrigerant

• Purchase the correct type of refrigerant for your
  vehicle
• The easiest way to determine the correct type of
  refrigerant for your vehicle is to check the year
  it was made. All vehicles built after 1995 use
  R134a. If your vehicle is older than that, it
  likely used R12.
• You cannot refill R12 refrigerant on your own.
• If your vehicle uses R12, you should schedule an
  appointment with an auto repair specialist to
  convert it.

• Check a thermometer for the ambient temperature
•  In order to read the gauge on the refrigerant,
  you need to know the current temperature in your
  environment. Refrigerant occupies a different
  amount of space within the can and air
  conditioning system at different temperatures,
  causing the gauge to read differently at
  different times.
• Knowing the ambient temperature will allow you to
  effectively read the gauge on the refrigerant
  can.
• When refrigerant expands to take up more space,
  it increases the pressure in the can.

4

• Locate the low-side service port for the air
  conditioning
• Your air conditioning system will have two
  service ports a low side and a high side port.
  When recharging your air conditioner, you will
  need to locate and identify the low side service
  port.
• You can find the low side service port by
  following the lines from the A/C compressor until
  you find a nozzle near the bottom of the car.
• Refer to your vehicles service manual to help
  you locate the port if you are unable to.

5

• Use a rag to clean the area around the service
  port
• Make sure you dont clog the service port with
  any grime or debris by wiping off the port, cap
  and area around it with a rag. Wipe the cap and
  the line first, then remove the cap and wipe off
  the port itself.
• You can spray brake cleaner onto the line to help
  you clean it if need be.

6

• Attach the charging hose to the low side service
  port. Take the hose that comes with the
  refrigerant refill kit and connect it to the low
  side service port you identified earlier. Make
  sure the opposite end of the hose is connected to
  the nozzle on the can . If your can came with a
  gauge, the hose should be connected to the nozzle
  on the gauge and then to the can.
• The hose should be long enough to allow you to
  connect it to the port without placing the can
  all the way into the engine bay.

7

• Use the ambient air pressure chart on the gauge
  to determine pressure
• Read the gauge display while taking the ambient
  temperature into account to determine what level
  the refrigerant is currently at. Once you begin
  spraying, you will need to keep an eye on the
  gauge to determine when the system is full.Keep
  an eye on the gauge throughout recharging the
  system to know when to stop.
• Read the instructions on the can if you are
  unsure of how to read the gauge.
