Does it still have R-12 in it or did someone convert it?

If you have r-12, you really should get it evacuated by someone who can recover it. Best for the enviroment. They shouldn't charge you, as they can reuse that crap I belive. I know I wasn't charged when I took my honda in when I converted it.

You COULD just evacuate it into the air, but that isn't great for mother nature.

If this is for a track car, then do it. Before you disconnect the entire A/C, just unhook the belt. Once its out, there is no turning back and you may regret it during hot summer months.

This is VERY true. Wait till June/July to pull it and decide it the weight loss is REALLY worth it.

On that note, I need to find a shop here in town to add some freon to my system. Have a few cans I found in a garage. Those things are like gold and I dont' want to waste it by doing it myself.

there are schraider vavles (same as car tire vavle stem) & you push them down to evacuate it... if you dont want the hassle of taking it somewere & your not a nature nut... but reusing it does sound like a good bet, if its r-12.. as for weight, the compressor weighs about 20 pounds, about 5 in all the lines, 10 in the evaporator box, and about 5 for the condenser. o and i'd guess 5-10 for the steel compressor mounting bracket. those are all estimates, so it adds up to about 50. not too much, a little bit. does make the engine bay look alot better. but not worth it if you hate being hot, lol. have fun

To vent is easy. Just push in the little button located under the black caps.


And yes, I will ship it to whoever wants it.
