How do you get a 1986 Volvo to take freon?

Answer 1

Everyone will tell you it's better to take your car to the shop to have AC work done. It can be dangerous and illegal to vent the freon into the atmosphere. But first of all, we need to know if the AC has been converted to R134A? If it's R12 you're going to have to convert it to the readily available R134A. If it is already R134A and by "to take freon" you mean add freon, then you add it to the low pressure side port. It's said that the hose that connects the can to your AC system won't connect to the high pressure side, but do not even attempt to do this. Thus the dangerous part earlier. I have heard it can explode. The low pressure side fitting is usually under a blue cap. And the high side is under the red one. Also do not overfill. This can be dangerous as well. If you have added a can and it's still not getting cold inside do not continue to add any more. Something is probably broke and adding more freon won't help it. But once again it is recommended to take it to the shop.
