Converting an R12 to the R134a car A/C system is not a difficult task. In fact, it can be done in a few simple steps. Here’s a guide to ensure that your car’s A/C system is properly converted to the new R134a refrigerant.
Discard the R12
When you’re converting your car’s air conditioning system from R12 to R134a, it’s important to follow the proper procedure. First, you’ll need to discard the R12 refrigerant. While it may be tempting to try to do the job yourself, it’s best to leave it to a licensed professional. They will have the tools and experience necessary to properly recycle the old refrigerant. Taking care of this now will help you avoid problems down the road and will help protect the environment.
Retrofit the System
When you convert your car’s air conditioning system from R12 to R134a, you will need to retrofit the system. This involves replacing some of the parts in the system, such as the compressor, condenser, and receiver/dryer. You will also need to add an R134a adapter kit to the system. The steps for retrofitting the system are as follows:
- Remove the old compressor, condenser, and receiver/dryer from the system.
- Install the new compressor, condenser, and receiver/dryer.
- Add the R134a adapter kit to the system.
- Replace the fill port cap with an R134a cap.
- Check for leaks and repair as necessary.
- Test the system and adjust as needed.
Hook the Gauges
When you’re converting your car’s air conditioning system from R12 to R134a refrigerant, it’s important to hook up the right gauges. Otherwise, you could damage your car’s A/C system. The low-side gauge should be hooked up to the service port on the low-pressure side of the A/C system. The high-side gauge should be hooked up to the service port on the high-pressure side of the A/C system. Make sure that the gauges are appropriate for the type of refrigerant that you’re using. If you’re not sure, consult a qualified technician. With the right gauges in place, you can be sure that you’re safely and correctly converting your car’s A/C system.
Pump the R134a
In order to add R134a refrigerant to your car, you will need to connect the yellow hose to the R134a can. This oil should be included in the refrigerant already; however, if it does not, you will need to add oil separately. Once the hose is connected, open the valve on the can and hold the can upright so that the refrigerant can flow into your car’s system. Be sure to keep an eye on the level of refrigerant in the can so that you do not overfill your car’s system. When you are finished adding refrigerant, close the valve on the can and disconnect the hose.
How Much Does it Cost to Convert an R12 to the R134a System?
The cost of converting an R12 to the R134a system will vary depending on the size of your car and the amount of work that needs to be done. However, in general, the cost of conversion will be around $250. Remember that the R134a system is much more efficient than the R12 system. In addition, it is also significantly less harmful to the environment. The cost of conversion is well worth it for those who are looking to save money and help protect the planet.
