Question about 1994 Ford Taurus
First thing: Be extremely careful! Secondly, I'm not sure what year that all the auto manufacturers switched from R-12 refrigerant to the R-143a, but if your car came with a system that used R-12, you need to buy the conversion kit that includes the modern retro-fittings (adapters) because on an outdated system, both service fittings on the car's service ports will be too small for the modern updated attachments R-134a refrigerant charging attachments (they made the fittings between the two systems different on purpose). R-134a is not compatible with R-12 at all and if the two are running in the same system, it can cause irreparable damage to the refrigerant (A/C) pump and can even potentially cause the pump to seize, throw the accessory belt and then cause the motor to overheat and seize because the water pump no longer has a belt to turn it.....This is what I mean by BE CAREFUL. Check the tags under the hood because they will specify which refrigerant was used. If it IS an R-12 system, you need to take it to a qualified A/C Technician who can evacuate the lines of all the R-12 (freon) in the system. Not only is it more thorough to go to a qualified Tech. for this, but R-12 is not environmentally friendly and causes damage to the ozone layer.....Most people either don't know or don't care and will just evacuate the lines them selves with a valve stem core remover or a nail to depress the pin on the valve... I don't recommend that method but it is up to you.
If your system IS in fact an R-134a system, then just add the O-ring oil and the refrigerant as directed.
At any rate, your original question was where the low service port was located and I'm sorry about the novel I wrote you, but I'm just I'm just trying to be thorough and look out for you at the same time.....BUT the location varies by manufacturer and model but just find the A/C pump then follow the two "send and return" lines going back towards the passenger compartment. You will eventually find a service port on one of the lines. The other line goes to the accumulator which looks like a big aluminum canister. The other service port is located here and should be on the side of the accumulator towards the top. Good luck!
