Remove the hood.
2. Find the refrigerant fill port on the system’s low pressure side. A little plastic lid with a L printed on the top will be attached to this. To access the port, unscrew this lid.
The low pressure side fill port is often found on the left side of the engine bay on most cars. It frequently takes the form of a short metal pipe with two lengths of rubber hose emerging from either end. Look at the “firewall” at the back of the engine compartment. There should be two pipes or hoses sticking out from the firewall, one bigger than the other. The low pressure side fill port can be located by following the longer hose. The photographs show where the fill port is on two various late-model engines.
DANGER! Never handle anything you’ve never handled before. Nearly everything in the engine bay is in motion or becomes warm. Do not touch the high pressure side’s tiny pipes; they become quite hot. The low pressure side hoses can be touched, and they should be at room temperature.

What type of refrigerant does Nissan employ?
All automobiles produced for US sales beginning with the 2021 model year must feature R-1234yf A/C systems. The performance of Nissan’s new R-1234yf system, which it replaces, is designed to be comparable to that of R-134a systems, making the transition easy.
Does AutoZone inspect the AC?
You may find out if your AC unit is receiving electricity and whether the compressor is operating properly by having AutoZone test it with a digital voltmeter.
Depending on the make and model of your car, AutoZone could also be able to supply new parts for your AC unit.
To identify the appropriate parts for your automobile, we advise speaking with an AC specialist or the owner’s manual for your particular vehicle.
How long does it take the air conditioning to cool down after a recharge?
Soon after the recharge is complete, your air conditioner should begin to blast cold air. Even though certain systems might take longer, the time after the recharging process shouldn’t exceed two hours. Any of the following causes could be the issue if the air conditioner doesn’t get cold after being recharged.
1. The AC and the automobile compressor are not connected.
Refrigerant troubles in a car air conditioner are frequently caused by compressor problems. This could be the cause if you discover that the AC is still blowing frigid air after being recharged. That will require you to visit a mechanic so the AC may be checked out.
Why isn’t the AC functioning in my Nissan Versa?
A refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor are the three most frequent causes of an AC failure in a Nissan Versa. Before the air conditioner quits blowing cold, you might not be aware that there is a refrigerant leak.
My automobile can I install Freon at AutoZone?
Check out our list of recommended stores in your neighborhood for assistance if you need assistance with this or any other AC recharge or service. Alternatively, AutoZone has all the equipment and refrigerant necessary to service your R-134A or R-12 car if you choose to handle the work on your own.
How can you tell whether your automobile requires Freon?
If you pay close attention, you can hear a “click” when you turn on the air conditioning in your car. This is the clutch engaging. There won’t be enough refrigerant for the compressor to pressurize if the Freon levels are too low because the clutch won’t engage. In other words, there is nothing for your air conditioning system to operate with!
Can I fill my own air conditioner with freon?
You shouldn’t ever have to add refrigerant to your air conditioner yourself, as you are unable to do so. Before being dispatched to retailers, air conditioners are either factory-charged with the appropriate amount of refrigerant, or they are dry-charged during installation. A low refrigerant charge indicates that it was either charged insufficiently at the manufacturer (very improbable) or by your installation professional (not if you worked with us), as refrigerant is not consumed by your air conditioner at any stage in the system’s operation. maybe there is a leak.
Unfortunately, the majority of homeowners encounter that last issue. One of the most serious issues with your air conditioning system that you might experience is a refrigerant leak. Low refrigerant charges put your comfort and your finances in danger, and using an air conditioner with little refrigerant can seriously harm your system. If given the chance, it might potentially damage your compressor. In these situations, a complete AC replacement is frequently the outcome.

Is 134a and R134a different from one another?
According to a search on the Dupont website, 134 auto can be applied in business settings.
What, if any, differences exist between the two?
Tetrafluoroethanes (1,1,2,2) and (1,1,1,2) are the two different types.
Where on the Dupont website did you find this? I looked, but I couldn’t find anything about CHF2-CHF2 being utilized in refrigeration systems.
The two are basically different in how the atoms are joined to produce the chemical molecule.
Due to the symmetry of the way the atoms are connected (CHF2-CHF2), R134 does not have a letter following the number designation.
The letter “a” is used to identify R134a, which is the only other isotope in this situation. The atoms are employed in the identical type and quantity; they are simply connected differently (CF3-CH2F).
According to my study, R134 is mostly employed as an expansion agent in foam applications. It appears that R134 really performs far better than R134a in this kind of application.
Why R134 is not used in refrigeration applications is something I’m unsure of. Perhaps it is related to the boiling point difference between R134 and R134a.
What I did learn is that R134, along with R134a and a few other refrigerants, was actually tested as an R12 replacement many years ago. As a prospective replacement refrigerant, R134 did not “pass the test,” but I was unable to pinpoint why.
I have a suspicion that finding a jug of R134 would be difficult for us wrench jockeys, but I could be mistaken.
What distinguishes R12 from 134a?
Many people wonder what kind of refrigerant is used in their cars, regardless of whether they are newer or older. Even though it could initially appear to be confusing, it isn’t once you understand the differences and what to look for. You can determine what kind of refrigerant is in your automobile with a little detective effort, too.
The refrigerant used in vehicle air conditioners comes in two varieties. R12 is the name of the first one, whereas R134a is the name of the second. Even if they have similar sounds, there are significant variances between them. R12 was initially the one that was on earlier cars. It goes by the brand name Freon, and after researchers discovered that it contributed to the ozone layer’s thinning, it developed a negative reputation.
Some older vehicles still use R12, particularly those that have not been upgraded to a more contemporary and ecologically friendly system. Prior to 1995, R12 refrigerants were utilized. Therefore, if a car featured air conditioning, this was a standard feature. Since then, some people have upgraded their air conditioning systems, and all automobiles made after 1995 come equipped with R134, a refrigerant that is thought to be environmentally friendly.
Does your vehicle AC have 134a refrigerant Here is how to tell
Start by thinking about the year of your car to see whether it has R134a. You should have R134a in your car if it was made after 1995. R134a may still be in an older vehicle; it all depends on whether it has been converted. Look for a sticker identifying the under-hood unit as R134a to determine whether it has been converted. Additionally, keep an eye out for R134a adapters, which are typically found on the charge components.
If so, does it use 134a refrigerant? Here’s how you can tell. Why not visit a store if you’re still unsure about the refrigerant type you have? You’ll discover what kind of refrigerant you have in a matter of minutes. Also included are your options if you require any services. Alternatively, if you have an older model and would wish to convert it. You can quickly travel to the refrigerant that is better for the environment!

What occurs when a car runs out of refrigerant?
Low Freon levels in your car can frequently be detected by obvious Freon leaks. In its liquid form, freon resembles grease, but it also contains a small amount of oil, which enables it to lubricate the compressor. Check all of the system’s components if you think your car’s air conditioning system is leaking Freon. Make careful to check the compressor’s pressure lines, service ports, front shaft, accumulator, condenser, and all fittings that connect to it. You can have a Freon leak if these components start to form a film or liquid stream. If this film or stream reappears, your car most likely has a Freon leak or is low on Freon. Wipe it off to be sure.
Depending on the amount of freon present, the car air conditioner will either blast cold or hot air depending on the setting you choose. One of the most obvious symptoms that the Freon levels in your automobile are low is when the AC blows warm or hot air when it is set to blast cold air. The absence of Freon prevents the system from being pressurized and circulated.
Quick disconnect fitting for AC recharge charging port
Some recharge kits have this fitting that quickly and securely connects to the AC recharge charging connector.
Your air conditioner probably lost some refrigerant during the winter if it was blowing ice-cold air last year but is now hardly cooling. When aging seals shrink and some refrigerant leaks out, that occurs in older automobiles.
Typically, turning on the automobile air conditioning will send you back to the freezing cold. If your car was built after 1993 and is filled with R-134a refrigerant, you can complete that task by yourself (to make sure, check the label under the hood or the specifications section of your owner’s manual).
Restrictions may apply to the sale of R-134a refrigerant to consumers in several states. The cans may occasionally be designed differently, necessitating various charging techniques. All AC issues won’t be resolved by charging the AC. However, if you’re willing to risk $50 on a rechargeable ac kit, you could become a cool dude in less than an hour. By performing the auto ac recharge yourself, you can save roughly $100 on labor.
Pick up an R-134a A/C recharging kit at any auto parts store. Because it included a quick-connect fitting and reusable gauge, as well as a seal conditioner ingredient in the refrigerant, I used the A/C Pro product you see here. For an AC recharge for a car, however, any brand will work. A word of caution: Many commercial recharging kits utilize oils and seal conditioners that are incompatible with the electric AC recharge compressors in hybrid vehicles. A fatal electrical shock might be caused by using the incorrect auto ac recharge kit. Before making a purchase, verify that your hybrid vehicle is compatible with the car ac recharge product on the label. Consult a professional if you’re unsure.
