Re: refrigerant capacity ?
You need about 30-36 oz of r-12 or convert it to r134 the red tek product is terrible, one of my business friends here in colorado is actually the co owner of the company (and you guessed it .... his name is red :) )
i have never had the stuff work worth a dang but the retrofit kit (35-50 $) that you can buy at any walmart or auto part store always works awesome and comes with a guage to tell you when it is full :)

If you mean "how much does it hold" there is a sticker in the engine compartment or on the compressor that gives the capacity. On that kind of car, I would say total capacity would be around 4 cans or 3 lbs. That is if the system is empty and has a vac when it is filled.
The A/C Fill port is the low pressure service port on this diagram;
It is located on the larger diameter aluminum tube coming back from the evaporator and firewall, to the A/C compressor. The fitting will have a taller skinnier cap on it, that may be blue or black. Not red. The R134a refrigerant cans will not connect to the high side port. This is good since the can could potentially explode/vent causing a sort of instant cryo frost bite to exposed skin. I recommend wearing gloves when recharging A/C sytems, especially if you are new to refrigeration systems.
Total PAG oil capacity is 8 ounces if completely empty Total Refrigerant charge is 1.6 pounds oil replacement with just changing certain items as follows. Compressor Replacement add 2oz Condenser replacement add 1oz Evaporator Replacement add 3oz Remember to rate my solution and give testimonial this is how i earn my achievements here on FixYa.
First of all, the AC has nothing to do with the coolant in the radiator, they are two different systems. You need to have an AC technician check for refrigerant leak in your AC system. As far as getting rid of the water you added to the coolant, depending on how much of the total capacity you filled, you may have to drain the entire system and refill with a 50/50 mixture.
Most likely due to low refrigerant... Need to have the ac refrigerant refilled to capacity.
You should also check all your fuses. Since the 30amp A/C fuse may have blown or burnt out.
Fortunately the vehicles warning system seems to have stepped up and did it's job..., but this may have been after a fuse was blown..
Be sure to refill your A/C refrigerant in accordance to the proper level defined by the ambient air temperature (outside air temp where your vehicle is located).
Most common cause of your problem is a leak in the AC system. This causes loss of refrigerant. There are AC kits to refill refrigerant but unless you find the source of the leak and repair it, a refill kit will only work temporarily.
If the refrigerant is low /the coolant is low then AC will not work. But the heater will work.In this case the refrigerant needs to be refilled from car ac service center.Its not advisable to fill the refrigerant manually.So getting it done by a professional is very much advisable.
But refilling the refrigerant should solve the problem.If there is no refrigerant leak.At the ac service center,they will confirm this before refilling refrigerant.
Keep updated for any more queries.Thanks.
Find the A/C compressor. You will see a large line and a small line. Follow the larger line all the way back to the firewall. You will see what looks like a tire valve stem with a cap on it. That is you low side refrigerent service port.
In most cases, the problem is the system is low on refrigerant. The AC compressor requires a minimum of 20psi of refrigerant to turn on. There are refill kits available at the auto parts stores. If doing this yourself, select a kit that includes compressor oil, and a refill hose.
RECHARGING AC SYSTEM
Turn the truck on and turn AC on HIGH
Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
Insert the other end of the refill hose to the low side valve
Puncture the R-134A can with the screw on the refill hose
You should feel the system suction the refrigerant out of the can
Check for frost on the AC lines and the air blowing inside the truck
If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Hopefully this answers your question and you're able to get your AC working again. Best of luck.
