If you prefer to talk verses type then please use the phone call option.** Hello, if the orings are missing, the green dye in the freon is what you see leaking out of the expansion valve. You will need to replace the seals and evacuate and recharge the ac system.

Can I do that without using a vacuum pump?
Automotive Expert
No, the system must be evacuated or it will not blow cold air.

Ok thank you. I also have another question. Yesterday, my car wouldn't start, so I tried resetting the fuses and then it started fine. Today, It turned on and then turned off a few seconds later. I would love to know why
