How to Put Refrigerant in Your Car
Putting refrigerant in your car is an important step to maintain a comfortable climate inside your vehicle. Refrigerant works by cycling through the air conditioning lines and evaporator of your car’s system, releasing cold air. Doing it yourself is more cost-effective than having somebody do it for you. Here are the steps you need to take:
Tools and Materials Needed
- Socket wrench
- Socket extensions
- Socket set
Step 1: Locate the Air Conditioning’s Low-Pressure Port
Your car’s air conditioning system has two ports, a low pressure and a high pressure, that refrigerant flows between. You need to locate the low pressure port first. It is typically labeled on the compressor or near the compressor. It’s usually the largest, most visible port.
Step 2: Loosen the Port Cap
Using your socket extension, loosen and remove the port cap. This will give you access to add the refrigerant. Put on your safety gloves, goggles and clothing to protect your skin and clothing.
Step 3: Attach the Refrigerant Can
Attach the refrigerant can to the low pressure port and tighten it with a wrench. Be sure to wear gloves and goggles while handling the can, as refrigerant can be dangerous. Make sure the can is securely attached before moving on to the next step.
Step 4: Let the Refrigerant Flow
Once the can is connected, carefully open the valve on the refrigerant can. The refrigerant will then begin to flow through the lines of your car and start cooling the air. Monitor the pressure gauges on the can to make sure that the correct amount of refrigerant is being added.
Step 5: Close the Valve and Detach the Can
Once the pressure has stabilized, close the valve on the refrigerant can and detach it from the low pressure port. Make sure to tighten the port cap to prevent any leaks.
Now that you have put refrigerant in your car, you are all set to enjoy a comfortable and cool ride. If you have followed the steps carefully, you should have no problems with your car’s air conditioning system.
