Can be added with refrigerant check can contents
System pressure will run abnormally high, the AC system will vibrate, and you won't get proper cooling.
The AC system will vibrate, and pressure throughout the system will be extremely high.
The amount of oil charge required for an automotive AC system is specific to the car. There is not standard amount for all cars.
FYI most refrigerants already have oil that is proportionate to the amount of refrigerant in the can. If you are using straight refrigerant and all you need is to add oil to your system, then there is product out there that is straight oil that can be added to the low side port in your ac system. IDQ , QUEST , and AC PRO are some companies out there that have many of these products. You can also find them in the web at www.idqusa.com along with helpfull information about your vehicles ac system.
Ac oil helps to keep the gaskets in the ac system from drying out. The oil can be added separately or can be bought mixed into Freon from the store. Most importantly the oil lubricates the ac compressor, the only moving part in the ac system.
Under the hood, on the passenger side, just next to the firewall is a silver can-looking thing that has AC lines running in and out. The can, called a 'receiver/dryer' may, or may not, be wrapped in black foam. The AC line coming out of the receiver/dryer has the low pressure side port, that's where you add refrigerant and/or oil. Don't add oil unless you KNOW that it's low. Too much refrigerant oil can destroy the AC system.
You have a system performance test done on your AC system.
By buying an AC charge hose and a can or 2 of R134a freon (depending on how much your car needs) Attach hose to the low pressure side & charge system. Do not overcharge, or you may destroy the AC system.
The AC condenser would effect the performance of the AC system in the car.
To properly add refrigerant to an AC system, you need to first locate the low-pressure port on the system. Then, attach a refrigerant gauge and hose to the port. Start the AC system and slowly add refrigerant until the pressure reaches the recommended level. Be careful not to overfill the system.
To add refrigerant to an AC system, first locate the service valves on the unit. Connect a refrigerant charging hose to the low-pressure service valve. Turn on the AC system and slowly add refrigerant until the pressure reaches the recommended level. Be careful not to overfill the system.
There are several pressure switches in a vehicle. The engine has an oil pressure switch that sends a signal to the oil pressure gauge oil or light for you to monitor. Some oil pressure switches can shut down the fuel pump if no oil pressure is detected. The AC system has both a low pressure and a high pressure switch to protect the AC system from self destruction.
