R-12 Freon

R-12 Freon, also known as CFC-12, was widely used in older vehicles. However, it’s been phased out due to its harmful effects on the ozone layer.

If you own an older Nissan Altima, you might find that it uses R-12. In such cases, it’s advisable to retrofit your AC system to accommodate R-134a or R-1234YF for a more eco-friendly option.

Older Freon Types: What You Need to Know?

R-12 Freon

R-12, also known as CFC-12 or Dichlorodifluoromethane, was the standard refrigerant used in automotive air conditioning systems until the early 1990s.

It was effective in cooling but had a significant downside: it was extremely harmful to the ozone layer. The release of R-12 into the atmosphere contributed to ozone depletion, leading to increased UV radiation reaching the Earth.

R-22 Freon

Another older type of Freon is the R-22, commonly used in home air conditioning systems but occasionally found in older vehicles. Like R-12, R-22 is an ozone-depleting substance and is being phased out.

If your older vehicle uses R-22, you should consider retrofitting your AC system to use a more eco-friendly refrigerant like R-134a or R-1234YF.

Retrofitting Older Systems

If you own an older Nissan Altima that uses R-12 or R-22, retrofitting is an option. Retrofitting involves replacing specific components of the AC system to make it compatible with newer, eco-friendly refrigerants.

It’s a one-time investment that not only benefits the environment but also makes your AC system more efficient and cost-effective in the long run.

How To Check Freon Levels In Nissan Altima?

Step 1: Safety First

Before you begin, make sure you’re wearing the proper safety gear, including gloves and eye protection. Freon can be harmful if it comes into direct contact with your skin or eyes. Ensure that your vehicle is parked in a well-ventilated area, away from open flames or sparks.

Step 2: Locate the Low-Pressure Port

Open the hood of your Nissan Vehicle and locate the low-pressure port of the AC system. This port is usually found on the larger of the two aluminum pipes that come out of the AC compressor. The port will have a cap that you’ll need to unscrew.

Step 3: Attach the Gauge

Take your AC pressure gauge and attach it to the low-pressure port. Make sure the connection is secure to get an accurate reading. Most gauges are color-coded or have a dial that indicates if the Freon level is low, optimal, or high.

Step 4: Start the Engine

Start your vehicle’s engine and turn the AC to the maximum setting. Allow it to run for a few minutes. This will give the compressor time to engage and circulate the Freon.

Step 5: Read the Gauge

After a few minutes, check the gauge reading. If the needle is in the green zone, your Freon level is optimal. If it’s in the red zone, you have too much Freon and may need to release some. If it’s in the yellow or white zone, you’ll need to add Freon.

Step 6: Adjust Freon Levels

Based on the gauge reading, you’ll either add or release Freon to bring it to the optimal level. If you need to add Freon, connect a can of the appropriate type to the low-pressure port and release it slowly while monitoring the gauge.

Step 7: Recheck and Disconnect

After adjusting the Freon levels, remove the gauge, replace the cap on the low-pressure port, and close the hood. Run the AC again to ensure it’s cooling as expected.
