recharge AC?

roll the windows down and don't stop moving

If it has r12 the service ports well be the size of a tire stem. If its r134 then the ports well be twice the size. You can still do r12 but very expensive unless you have a friend in the auto repair that gets the r12 from the wrecking yard from recycled cars.

the easiest way to tell is that the ports will be different sizes. and will be quick couple system.

Also the oil from R-12 is not compatable with 134a, so you might as well flush your system replace the orings and pull a vacuum test to see if there are any leaks. then put new oil in and when you retro 134a from R-12 you only fill to 80% capacity because 134a expands so much more than R-12 did. I just wish we could use R-12 cost effectively. cooled better.

Donen't R-134 require a different pump?

If it has been updated to the new refrigerant, you should see a sticker under the hood.

All in all, unless your camaro is a collector, it will cost more than the car itself...

no the compressor should work fine, but every year or two he might have to top it off because the 134a molecule is smaller than the R-12. and if the hose is old enough 134a can escape through a hose that held R-12 just fine.

my gawd man the sky is falling !!!!!

Just trow a couple cans in and see how she works...I mean it's an 84 camaro after all. How long since it's worked? Seals might be all dried up and shot if too long. Get the big 22 OZ can with 134 and leak sealer and has a gauge on it. Get another can with oil charge and 134. Chances are you don't have any thing left in your system to bother purging it or bother draining the old oil. Probably take awhile before the compressor will kick on and run more than a few seconds. I been running several old un-converted R-12 junkers that way for for many years and they still cool fine. If I lived down south that would be a different story, but up north you don't need all that much cooling. Throw another can or two in next summer and run it some more. Not the "right" way to do it, but it'll work good enough for MN.

Watch what you're buying if you're jamming a can or two of that replacement crap in a can that a lot of places will try to sell you. I know Red-Tek uses propane as a propellant and it's dangerous because of the flammability. We've got a bulletin from Occupational Health and Safety here at work on it.

Take it to someone that knows, and get a quote. This is the best way.

I agree. Try to find a leak by checking the hoses and front of the compressor for spots with dirt built up. If theres a leak don't fix it with the can of freeon with a sealer. Just gonna give you troubles down the road. Get it fixed the right way. Got any buddies that work at a car/truck/tractor shop? See if they'll give you a hand.
