Hey all,

One of the projects I am going to be tackling with my truck is installing onboard air. I am going to swap my compressor for a York 210 but First I want to disconnect my current A/C setup and discard the extras I wont need, its not connected to the belt, but still has the coolant lines connected to the compressor.

How should I remove these lines?

Are they still probably pressurized?

Just cover my face and go for it?


Thanks Again,
Devin

 

it would be best to take it to a shop that services air conditioning on vehicles, and ask them to evacuate the system for you. they'll hook up a vacuum pump and leave the system empty for you.

but if you can't or won't do that, park outside somewhere, preferably away from people, loosen one of the lines until it starts to hiss, then walk away for an hour as the system drains. the refrigerant is toxic, so you really don't want to be breathing it. it sometimes happens that disconnecting one line won't be enough to fully drain the system, so don't be surprised if the second line you disconnect is also under pressure. if it is, walk away again as it drains.

 

You should be able to find a tire-like valve - with a screwdriver see if it's got pressure. If you do, and the truck is original, and you're in the right forum, most any small garage will be happy to draw it down for you to gain the R12.

Just venting it yourself is a bad idea, illegal, and a waste of good R12.

Cheers,

+1. Find the service port, remove the cap and depress the valve a bit. If gas comes out take it to a shop and have it evac'd. If no gas comes out carefully unbolt the lines. In the off chance that there is gas in there and it starts coming out just move away and let it vent. Freon is heavier than air and you definitely don't want a lung full of it.
