Adhere to all directions on the tag, consisting of additional suggested safety gear.
- Locate the reduced stress line port, which will have thicker tubes. There are two ports on your ac unit. You will add the refrigerant to the low stress line port, not the high pressure line port. The reduced stress line has bigger tubes than the high pressure line, making it very easy to distinguish between the 2.
Often they are labeled with “H” for high and “L” for reduced. In some vehicles, the reduced pressure line port will be lower than the high port, yet this is not constantly the case.
Most kits have a connection that only fits onto the low stress port, making it easier to pick the best port.
- Get rid of the port cap by loosening it. The cap is the little plastic cover that seals the shutoff. Once it’s off, make sure you place it somewhere safe to ensure that you do not lose it.
- Hook the pressure scale hose to the port. Merely click the gauge adapter over the open port. You can shake it gently to see to it it’s attached.
If it’s loose or comes off, attempt to connect it again.
It’s ideal to choose a recharge package that comes with a pressure scale. This enables you to conveniently add even more refrigerant without overcharging your ac system.
- Check the analysis on the pressure scale. The gauge will certainly supply a reading in psi. It ought to have colored areas to show if it remains in a secure variety. Eco-friendly means excellent, yet your degrees can still be lower than required to cool your vehicle if it’s low in the green zone.
Your suitable pressure will certainly be figured out as soon as you check the outdoor temperature. You’ll do this when you evaluate your system later in the recharge process.
- Wage the recharge if the pressure gauge reading is above 0. A reading of 0 ways that there is no refrigerant left in your air conditioner, which will certainly need a repair by a specialist technician. Or else, you can bill the system yourself using your charging package.
Testing Your System.

If it’s not rotating, after that you can add half a container of refrigerant and inspect it once again. If it’s still not rotating, after that you’ll need to take your auto in to an expert service technician.
- Set the refrigerant temperature level scale to the ambient temperature level. The gauge will tell you what your refrigerant pressure need to seek you complete your recharge. This is your recommended pressure level. As you recharge the ac unit, you can keep track of the pressure on your stress scale.
It’s alright to round up or down to the local 5 degrees.
- Examine the pressure gauge to see to it remains in the white or eco-friendly zones. The current pressure level must be listed below the suggested level you simply figured out, based upon the temperature level gauge reading that you took. If it’s over the advised level or at a loss area, you need to take your car to a professional due to the fact that another thing is wrong.  Do not add even more refrigerant if the levels aren’t reduced. This might harm your vehicle.
