just to let you know that princess auto has the air conditioning recharge kits on sale bought 2 and installed them in 2 81 LC's really easy takes about 15 to 20 min. now we can make ice again.

sale cost is $59.00 reg is $99.00 and it not princess auto junk it same one you buy from anywhere ells.
 
Thanks for the tip - picked up the kit a couple weeks ago - great deal. Anyone have a link to a step by step, one banana two banana write up? Never messed with AC systems before - replacing my AC clutch but no idear on how to drain and recharge the system properly...

cheers.

The main thing is to clearly identify your high pressure and low pressure line. Both may have factory or aftermarket valve taps. You put a can on the high pressure line and you could be seriously hurt when the can explodes. If you are using the F12 replacement which requires your system to be drained, best have a pro do it. Actually, it's the law. Unless you have a drier and vacuum pump, you will have to have a pro do it anyways. I believe there is a newer F12 replacement which can be mixed with F12 but haven't really paid much attention to it. My father was a refrigeration man and I still have enough to last me a lifetime. I actually ended up paying to dispose of some of his freon refrigerants a few years ago <before I learned about the black market value of them>. Of course, there are other considerations like the condition of the seals in you compressor.

the 2 valves are different sizes the tool only fits the one.

Must be newer models. The high and low pressure line valves use to be exactly the same - they are the same on my Safari. In fact, I think I have a box of refrigerant valve line taps lay around somewhere, if anyone needs some. They are pretty simple - just like a tire air valve.
 
The instructions on filling are straight forward but not a word about draining - guess I'll let someone with the right equipment evacuate the system for me.

Anyone mind grabbing an AC belt part # from their 1HD-T?

Thanks

To drain it properly, the system needs to be hooked up to a vacuum pump so all the old freon is evacuated to a larger gas tank for disposal. Even if you vent to the atmosphere (which is an environmental taboo), you need to vacuum the system before adding the new refrigerant. Also, if you vent to the atmosphere it now needs to be dried because the moisture in the air has now entered the system. I recommmend you let a pro handle change the exchange refrigerants. In the future if you need to top up, you can then do that yourself.

Tips:
1) To coax the last bit of gas out of the coolant can, you can put it in a bucket of warm water.
2) Freon gas is not poisonous but converts into a poisonous gas in a reaction with an open flame. Not sure about the new refrigerants.

I saw those canisters...I'm not too keen on them being that they are highly flammable. BOOM! :D

Are they propane? Propane does make a decent refrigerant. Although it does have a down side if it leaks around an ignition source - but not as bad as natural gas or gasoline.
 
I'm not sure...didn't take a close look at it but propane is the usual suspect, isn't it? The fact that propane makes a good refrigerant is readily evident when using a camp stove and the propane cylinder runs low...there's usually a nice layer of frost on the ouside of the cylinder.
