What refrigerant is used in a 1973 eldorado?
The original refrigerant installed at the factory in 1973 was R12 (Freon). If it has not been converted to R134a, I suggest you convert it now, if it is leaking and needs repair. R12 is no longer in production and the dwindling supply is very expensive. Much cheaper to convert it to R134a.
1996 Cadillac Eldorado...If msg reads AC low on refrigerant and AC compressor reads off will both problems be fixed by adding refrigerant?
Where can you get a wiring diagram for a 1973 Cadillac Eldorado with 500 V8 engine and auto transmission?
HELLO, I AM NEW IN THIS FORUM, I HAVE A 1973 CADILLAC ELDORADO CONVERTIBLE WHICH I AM RESTORING AND I HAVE THE SAME PROBLEM AS YOU DO. I FOUND THIS LINK, I DON'T IF IT MAY HELP YOU. http://www.tocmp.com/manuals/Cadillac/wiring/index-tt.html I BOUGHT THE SHOP MANUAL AND AT THE END OF IT I HAVE THE WIRING SCHEMATIC BUT IT IS ON A VERY BIG PAPER SIZE SO I DON'T KNOW HOW I COULD PUT IT ON INTERNET…
If you are having to add refrigerant, then this means you have a leak, and you will be adding refrigerant again in a few months. It is illegal to add refrigerant to a system with a leak without first repairing the leak. So, my advice is to take it to a professional and have the leak repaired and refrigerant added with the proper equipment, which you do not have.
You have a 2000 Eldorado and the low AC refrigerant light is on how do you shut it off so you can put in more freon you have done this before and have forgotten how?
Is it a new or an old window unit? Assuming your looking to refill it I will assume it is an old window unit which most likely uses R-22 refrigerant. R-22 is an ozone depleting refrigerant that is being phased out but should be available until 2010. There should be a label on the window unit stating which refrigerant is used.
Starting with liquid refrigerant: The pump pushes the refrigerant, under pressure, through an orifice The refrigerant sprays through the orifice into the low pressure side of the system The refrigerant flashes to vapor and absorbs heat from the coils of the evaporator The heat-laden refrigerant vapor moves into the condenser where the heat is dumped to the atmosphere and the refrigerant condenses to a liquid The liquid enters the pump and begins the cycle again.
It is R134a. Please under NO circumstances use the refrigerant that has stop leak added. If you have to take it to a repair shop and need repairs, it will ruin the equipment that is used to recover the refrigerant. Also, you need to be exact in the amount that is in the system. There should be a sticker under the hood with all of the information on it.
Check the refrigerant level. Your vehicle probably uses 134A refrigerant so it shouldn't be too expensive. If the refrigerant level is low, someone can add refrigerant for you or you can purchase the tools and do it yourself. Refrigerant is added with the engine running, and to the "low" side. Never allow the "High" side to be over pressure.
