How much freon does my car take

Seek the medical attention of a doctor immediately! The workplace must be well ventilated for working on refrigerant circuits. Breathing in high concentrations of gaseous refrigerant can cause dizziness and even suffocation.

Do not work on the refrigerant circuit from an inspection pit. As gaseous refrigerant is heavier than air, it can collect in high concentrations there.

Do not smoke! Refrigerant can be broken down into poisonous substances if it contacts cigarette ash. Do not introduce an open flame or hot metal in the immediate vicinity of refrigerant.

Doing so can cause lethal gases to form. Never allow refrigerant to leak out into the atmosphere. If the refrigerant reservoir or air-conditioning system is opened, its contents will escape under high pressure.

The extent of the pressure depends on the temperature. The higher the temperature, the higher the pressure. Do not expose any components of the air-conditioning system to heat.

If this cannot be avoided, drain the air-conditioning system beforehand. When removing the service tubes from the vehicle, do not point the connections toward your body.

Refrigerant residues may leak. When cleaning the vehicle, do not point the steam-jet cleaner directly onto parts of the air-conditioning system. How many cans of Ra does my car need? How much Ra does my truck need? What should gauges read on A? What should the suction pressure be on a A refrigerant? What should a C gauges read? How do you tell if you overcharge your AC? High energy bills. Air coming out of vents isn't very cold.

There's ice on your refrigerant lines. Note: Don't forget to fix the leak. One can of Ra typically holds 12 oz. If the system needs more refrigerant after adding one can, you can add a second can. Asked by: Mahir Voelchert home and garden indoor environmental quality How much freon does my truck need? Last Updated: 20th July, Most vehicles need 25 to 35 pounds per square inch of Freon on the low side if the vehicle is running with the air conditioner on its coldest setting and fastest fan speed.

The amount of Freon a vehicle uses is measured in pounds per square inch, or psi. Natascia Kanwar Professional. What should the gauges read on a? For a low pressure gauge , a reading of 25 pounds per square inch psi to 40 psi is optimum. On the other hand, a high pressure gauge should read between psi and psi. Volusiano Neuberger Professional. What are the symptoms of an overcharged AC system? In summary, there are seven symptoms or telltale signs of a system that has too much refrigerant.

High discharge temp. High subcooling in the condenser. High pressures in the condenser. Higher condenser splits. Normal-to-high evaporator pressures. Normal superheats. High compression ratio. Ebru Dickhans Explainer. Especially if you're topping your air conditioning system off yourself, this method might be cheaper than evacuating the system and refilling it completely, but the EPA warns that many auto shops charge the same fee for both services, so if you're having someone else do it, it might not be cheaper after all reference 1.

If you decide to extract all the Freon from your air conditioning system, you can charge the system with the precise amount of Freon that your car's manufacturer suggests. While the standard auto air conditioning system needs about three pounds of liquid Freon, the amount does vary, so check with your manufacturer or have your mechanic check.
