AC charge

[abodybill]

My 66 Valiant wagon needs an AC recharge so has anybody bought any of the kits that are on the ebay?

There's nobody within 75 miles of my place that can do it.

Don't even know if anybody in the city can or will do it.

Was on Ebay and they have alot of DIY kits.

Just wonder if they work?

They work to varying degrees, & can be purchased at any auto parts store. If you are converting to R134, the best way is to remove as much of the old R12 refrigerant oil as possible. The most effective way to do this is to remove components and dump the oil out. There will be some in the compressor crankcase, some in the dryer, some in the evaporator, lines, etc etc. This is not mandatory, it just makes for a more efficient system. The R12 oil does NOT mix with the R134 oil. It (the R12 oil) simply settles into low-lying areas and stays there. The down side, is that it takes up space in the system rendering it less efficient. The other way is to simply go through the evacuation process which will remove some - but not all - of the old oil. This is what most folks do. Once evacuated, you hook up the conversion kit and recharge. You can do this yourself, you just need a good vacuum pump. The cost of which may be prohibitive if you're only using it once. But it is a neat gizmo to have. I always recommend a new dryer as well.

Craig nailed it right on the head. I used to do A/C service back in my former life before I became a rich Saudi oil Baron. :acme:

I don't have to go thru the above if I'm going to put R12 back in it do I?

Reason I ask one of the farmers at church said he has about 15lb. of R12 left in the 30lb. bottle and said I can have it if I want.

Let me know.

Also Chris I'm also a oil baron but mine is all used oil :lmao:

Unless you are converting to 134A, there is no need to drain and change the oil. Pull a vacuum on the system, and if it holds over night, you should be good to go with the R12.

I was assuming that you may be converting, since you were talking about kits available on ebay...If you have access to good ol' R12, go for it! Once evacuated though, a small amount of oil will be removed. Probably less than a couple ounces, but still measureable. Finding R12-specific oil may be difficult. If it doesn't come in one of the kits, I have some if you need it.

I was going to convert but,after church this morning I was asked were's the wagon at and I told acouple fellows about the air and what I was going to do and the one told me I got what ya need and the best part he told me come and get it.

One of the guys I drive his truck for doing the sugarbeet harvest.

So I will pick it up this week and charge it up.

If staying with R12, the oil follows the refrigerant. So make sure to pull it into a vacuum for at least 2 hours and replace the receiver drier and then add the recommended amount of oil and refrigerant. If you don't ad the oil then it will wreck the compressor. R12 is less sensitive to over oiling than 134a.
