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.

Caution
If used incorrectly, refrigerant can result in frostbite and severe eye damage. Wear gloves and goggles when doing the process, and pay close attention to all the warnings in the package instructions.
Which side of the AC charge do you use?
Find the low side service port as the initial step in charging your device (or low-pressure port). There are two service ports on each auto air conditioning unit: one on the side with high pressure and one on the side with low pressure. For safety reasons, you should recharge with AC Avalanche refrigerant using the low side service connection. Never use the high side port to charge.
So, how do you find the low side service port?
Well, it’s typically found on the bigger diameter air conditioning line between the compressor and the evaporator. Find the compressor first. It is driven by the fan belt, which is located close to the radiator up front. A common auto air conditioner compressor looks like this:

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.
Is R134a compatible with HFC134a systems?
R134a and HFC134a are two distinct compounds, as can be seen from the information above, yet they can be used interchangeably because of their similar physical characteristics. The ODP values of R134a and HFC134a are both zero. Because of its low toxicity, it is a very efficient and secure replacement for the CFC-12 used in the refrigeration sector. The principal applications for R134a and HFC134a are industrial and commercial refrigerators, small stationary refrigeration equipment, medium-temperature refrigeration in supermarkets, and vehicle and home appliances.
How can I tell whether the AC in my car needs to be recharged?
Air from your AC is warm. Warm air blowing from your AC’s in-cabin vents is a warning sign that it needs to be recharged.
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.
What occurs if a car has too much Freon in it?
A refrigerant used in automotive air conditioners is called freon. On warm days, it is what keeps your car cool. However, a car with too much freon in it could have major issues.
The air conditioner blowing heated air, a hissing sound coming from the air conditioner, ice accumulation around the air conditioner vents, hazy windows, and a strong chemical smell emanating from the air conditioner are common signs of having too much freon in a car.
All of these are indications that your car’s freon system needs to be serviced as soon as feasible. In this article, we’ll go through the signs and symptoms as well as a solution, saving you money by preventing the need for costly AC compressor repairs and restoring your air conditioner to peak performance.
What should the AC pressure be in my car?
Run the AC system and start the engine. Visually inspect the compressor to see if it is operating.
- Was there a click when the AC was on? The central hub is it rotating?
- Watch the pressure meters. Does the high-side pressure begin to rise and the low-side pressure begin to decrease?
- Increase the RPMs to roughly 1,500 after the system has been operating for a time.
- The system should have a low pressure of 25 to 30 psi and a high pressure of 200 to 250 psi. The pressures will change in accordance with changes in the ambient temperature (70 to 80°F), which may be greater or lower than usual.
In my car, where do I place the Freon?
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.
How can I check my car’s Freon level?
It might be upsetting to discover that your air conditioner isn’t functioning properly. If you think the heat may be to blame, it’s a good idea to check the refrigerant level before visiting a mechanic.
You need the following to check the refrigerant:
- Thermometer
- AC meter
- security glasses
When you have your materials:
- Examine the air conditioner. Visit the mechanic as soon as you notice any worn-out parts or loose clamps.
- Once the pressures have stabilized, check the gauges. Between 25 and 45 psi should be read on the low port, and between 250 and 400 psi on the high port. You most likely have low refrigerant levels if both are low.
- If the temperature on the thermometer is 40F or less than the outside temperature, your air conditioning is operating as it should.
- Both the high-pressure service port and the low-pressure service port should be equipped with gauges. Between the accumulator and compressor on the passenger side of the firewall is the low port. The high port is located on the firewall’s line that connects the condenser and evaporator. Refer to your owners handbook if you are unable to locate the ports.
- Put the thermometer in the vehicle’s center vent, and then let it run for a while.
- Once connected, turn on your vehicle’s air conditioner and, if it has one, adjust the temperature to the lowest level while using the recirculating air function.

In a 2008 Nissan Altima, what kind of freon is used?
Our most well-liked Interdynamics Refrigerant & Chemicals items for a 2008 Nissan Altima include: R-134a PAG 46 Refrigerant Oil From Interdynamics Certified A/C Professional With ICE 32 (8 fl. oz.)
What happens if you charge your car’s AC on the high side?
You would suffer harm if you attempted to charge too strongly, not the system. It is highly possible that the pressure would build up within the container and cause it to explode like a grenade. Please, if you have no idea what you’re doing, ask for assistance. Always connect to the low side of the body.
How long does it take for the AC to start cooling off after a car 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.
