On the passenger side, close to the condenser, will be the low side service port (silver aluminum-cylinder shaped piece attached to aluminum lines).

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.
When ought the AC in a car be recharged?
Most of us are spoilt by modern life. We are accustomed to driving with adjustable seats, automatic transmission, and GPS to ensure we never get lost. For ultimate comfort, we also anticipate a cooling system that we can regulate to the ideal temperature.
You likely take the air conditioning on your automobile for granted. That is, until it perishes in the sweltering summer heat of North Carolina. Then you understand how much you value it.
The air conditioning in your car might be disregarded until it breaks down. I hope this doesn’t happen on a long drive away from your go-to neighborhood mechanic.
Alternately, you might plan routine AC recharge services. Most likely once every year or two will be plenty. The time to accomplish this is in the spring.
Can AutoZone fill my car with Freon?
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.
Do AutoZone air conditioners require recharging?
Most of the time, this may be resolved by using a trusted stop leak additive to halt any leaks. Visit AutoZone for an AC recharge when the time comes. Along with other things, we sell R134a refrigerant, PAG46 oil, AC stop leak, and AC system cleanser.
How can you tell if the Freon in your car’s AC is running low?
If the air coming from your air conditioner is warm or at room temperature, this is one of the most clear signs that you have low Freon levels. As we previously covered, this compressed refrigerant is circulated to power the air conditioning system in your car. Performance eventually suffers when the amount is too low.
How much R134a is required for my car?
The average automobile can contain between 28 and 32 ounces of refrigerant, or roughly 23 12 ounce cans, although larger vehicles and those with rear air conditioning will probably be able to hold more. The system capacity for your particular vehicle can be found in your car manual.
How can I refuel my car’s R134a air conditioner?
To replenish or top off the refrigerant in your car’s air conditioning system, turn on the engine, set the air conditioner to the coldest setting, and open the doors to prevent the air conditioner from shutting off when it gets cool inside the car. Let the engine and AC system run for about five minutes before adding refrigerant.
Toyota uses 1234yf, right?
Global desire for a more environmentally friendly and sustainable refrigerant has been sparked by environmental concerns. As R134a will be completely phased out by 2021, the 1234yf productalso known as HFO-1234yf and Rwas created to replace it. As a result, you’re likely to see more and more of it being used. R134a has been completely outlawed in a number of nations, and U.S. regulations are headed in that direction as well. If you run a vehicle repair shop, you’ve probably noticed a rise in the use of 1234yf in a/c systems.
According to Honeywell’s June 2018 Auto Refrigerant Update, 30 million automobiles will employ HFO-1234yf by the end of this year, with approximately 50% of all new models being produced in 2018. According to estimates, 1234yf is used by GM, BMW, Fiat, Land Rover, and Jaguar at a rate of over 95%; Ford, Honda, and Volkswagon at a rate of over 70%; Toyota, Subaru, Hyundai, and Kia at a rate of over 25%; and Nissan, Mercedes, Mazda, and Volvo at a rate of barely any conversions in their new models.
Refrigerant Depot delivered a sizable contract purchase to one of the manufacturers in 2018 who presently has 0% of its models using the yf gas, so you shouldn’t assume that they won’t continue in that direction in 2019. Change will undoubtedly occur, so if our technicians and service centers haven’t done so already, we advise them to do so.
Although the pipes, hoses, and sealing rings used in the systems for each refrigerant are similar, HFO-1234yf requires extra safety measures since it is significantly more combustible. Technicians should use the same caution they would while working with flammable fuel systems if they are not using modern RRR machines or a specialist recovery machine for the 1234yf refrigerant. The Honeywell HFO-1234yf and R-1234yf are the identical product; the only difference is that we sell the Honeywell HFO-1234yf in either 10 or 25 lb cylinders and the R-1234yf in 8 oz cans.
Do you fill the high or low side with freon?
Check what type of freon your car utilizes first. A tag indicating this should be located under the hood or on the radiator cover cowl. Search for 134A. This Instructable does not apply to you if it says 12. Although conversion kits exist, they are outside the purview of this demonstration. Now look at the illustrations to see what an AC system’s fundamental components are. We won’t talk about the pieces you can’t see because they are not important to understand in order to charge the system.
A pump or compressor in the most basic AC system transfers low pressure gas to high pressure. It is termed a compressor because of this. The high pressure gas then travels to a condenser in front of your radiator. You may have observed that while the air conditioner is on, your fan runs frequently. To cool the hot compressed freon, that chilly air is forced into the condenser. Then something fantastic happens. After cooling, the heated freon transforms from a hot gas to a semi-hot liquid. Count on me for this. The liquid continues to be under high pressure and at a high temperature until it is utilized to cool the evaporator.
It is no longer a liquid as it enters the evaporator; instead, it is a low pressure, cold gas. As soon as it exits the evaporator, it travels via hoses to the accumulator/drier, which is just a sizable tank for collecting any liquid that could have leaked out with the gas. After that, the cold, low-pressure gas returns to the compressor to restart the cycle. You may have noted that the system has two sides with different pressuresthis is VERY IMPORTANT. You’ll just be working on the side with little pressure. Only the LOW PRESSURE SIDE receives the freon addition. Since the fittings on the high side and low side are different in size and shape for safety’s sake, the hose tool you purchased is only designed to hook to the low side.
Why isn’t the AC blowing chilly air in my car?
The requirement for a recharge is the most frequent reason why a car’s air conditioner doesn’t get chilly enough. You can replenish your refrigerant on your own, but scheduling an appointment with a neighborhood reputable auto shop will save you time and ensure the service is done correctly.
