Hey guys, recently I came across a product from a company called Redtek. It's supposed to be compatible with R12 and R134.
I live in Canada, this product costs 80 bucks up here, which is about $63 U.S dollars. It sounds worth it. It is manufactured in Tennessee and avilable to both Canada and the US.
Has anybody heard or used it before? You can check it out at www.redtek.com Up here, you can buy it at a store called Parts Source.

My 91 Z has AC but it hasn't worked since I bought it (month ago)
I'm thinking of trying it out.
The problem is, I don't know if the clutch engages on my system, how can you tell? Can you physically see a clutch mechanism?


Thanks

 

you could always get some Freeze-12 from 'Reids if you still have and R-12 system... its only like $7 a can and it takes i think about 5 last i checked

 

It's a hydrocarbon refrigerant, which basically means it's a blend of propane, butane, and isobutane. Some people have had good results with it. Just be aware it is a flammable gas. This is what can happen with it.

If your system is in good sound shape, your condenser is clean, and your fans work, you can get good cooling performance from R134a. Most of the people who've had poor results from R134a got that from retrofitting a system that was in poor condition to begin with.

How much of it do you get for $80? I would hope more than enough to charge one car, for that price.

 

Alright. I bought the Redtek kit. It came with 3 R12 tp R134 adapter nozzles, 1 oil checker, 1 can of stop leak and two cans of Redtek coolant. I tried it one can my 94 GrandPrix and........
10 minutes later, it was blowing nice cold air. This stuff is awsome. I tried one can on my cmaro but then I noticed what appears to be a leak on the side of the Condenser. IT hisses pretty good. I see a little cloud of what looks like smoke coming out of that side. Bloody Hell, I bought this car just over a month ago and all kinds of crap keeps going wrong.

 

Did you know you can use Propane

 

I'm not sure what you mean.
Would you mind explaining?

Thank you

 

Propane has many refrigerant qualities.

Ever notice a 20 pound propane tank get frosty on the outside when there's a large gas appliance hooked to it? That's the propane absorbing heat as it evaporates inside the tank.

There are problems preventing propane from use in a MVAC though. It's illegal in most states, it's flammable. Also, it's pressure/temperature curve does not work for MVAC. The pressures are too high. With some improvisation, it could be made to work, but that doesn't make it a good idea.
