how many quarter i can add if i want make oil change for cadillac deville sedan 1996
Take it to the a auot shop. you can not add freon
In honesty, please bring your car to a reliable A/C repair shop because the system is built to hold a certain amount of freon. Any extra beyond that point is useless. I hope that this helps?
You add refrigerant to the vehicle ac system through the low side port. All vehicle are so there is a website with helpful information about your vehicles ac system, including with the low side port is locateded www.idqusa.com
on the low side only
You add the refrigerant through the low side service port.
You add refrigerant at the low pressure port but you do not add Freon. You add R134/134a. If you are having to add refrigerant then you have a leak that needs to be repaired first.
It is either on or near the recievr dryer in the right rear of the engine compartment. To corrrectly add freon, you need gauges and a refrigerant recovery system
