Simple auto repairs, like charging the air conditioner in your Toyota Corolla, can save you money, give you a greater understanding of how your car operates, and, most significantly, are simple.
Although adding freon to a Toyota Corolla is a fairly simple process, you’ll need to add R-134a instead because freon has been phased out due to environmental concerns. To refuel the air conditioning in your car, you should:
- Locate the low-side pressurized service port on the aluminum pipe leaving the condenser by opening the hood.
- Coupler for the recharge kit should be installed onto the service port without turning the valve.
- Roll all of the windows down, turn on the air conditioning, and start the engine.
- Allow the air conditioning to go as cold as it can while allowing the engine to warm up to its normal operating temperature.
- Turn the recharging canister’s valve while keeping an eye on the pressure gauge.
- Once you’ve reached the recommended pressure shown on the gauge, usually between 25 and 40 psi, close the valve and leave the canister connected for one minute.
- Continue watching the gauge and add refrigerant as needed, pausing one minute between spurts.
- After removing the coupler, give the air conditioner around ten minutes to operate.

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.
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.
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.
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.
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.
