Remove old R-12 for retrofit R-134 Kit

[ecmoteen2005]

Hello,

I have a 1993 Ford Ranger XL 2.3L with a 4-bolt air compressor with clutch. The current system is filled with R-12 but the clutch and compressor is bad, so I've bought another compressor from a compatible year model.

How do you remove the old R-12 oil from the system currently installed?

Are there certain procedures or precautions when removing the compressor, oil, etc?

Any information is greatly helpful! Thank you!!!

You take it to a licensed shop and ask for it to be recovered.

Trust me, it's A LOT cheaper than the EPA fine.

Most places won't charge you (my experience), or will only carge you a little....R12 is getting expensive!!! (I think a 30lb tank of reclaimed R-12 is listed for over $1500 now...)

Alternate refridgerant

Use Envirosafe available online. This is a Hydrocarbon (propane based) non-toxic, zero ozone depleting and compatible with almost any refridgerant and is 6.00 a can. It cools like R12. They even have an industrial version that is a bit more. It has a higher flash point than R134. R134 retrofits are crap. Don't even bother unless you get a new condensor and compressor. Envirosafe is the R12 of the future. It is used all over Europe and large corporations are looking into using this for cooling. It is much more efficient and has much lower high side pressures than R134. Read up on this before discounting it. Refridgerant is nothing more than a consumer scam. First R12 was cheap then they banned it and replaced it with cheap R134. Now R134 is expensive and being phased out. When will it stop?

Gee... if R-134 is such a big scam (that EVERY major vehicle manufacturer is using), it sure does seem to cool well

(converted from R-12 using the stock condenser, stock evaporator, stock (design) compressor on my '90)
Also, last I checked, a can of 134 was about $7 bucks

The biggest thing you have to do is make sure the system is completely CLEAN. If you had a compressor fail, chances are the condenser is contaminated with debris, and due to it's serpentine design it is basically impossible to flush out properly. You may have to replace that together with the compressor if you don't want the new compressor to fail too.

My post on converting my '90 to R-134a (should be almost exactly the same on your '93):

I've done a bunch of R134 retrofits. All worked very well. This isn't So Cal though. I have an R12 evacuator but, We haven't used it in a long time. I work on very few cars that are over 10 years old (at work that is).
