My AC stopped working a few weeks ago.
Where does the antifreeze go?
Does the car even take Antifreeze for AC?
I wanted to check if it's low and I couldn't find where it goes. I've looked everywhere[&:].

 

FYI, I don't have a service manual.

 

You won't be able to check the level. The AC is a closed system because of environmental laws. If you are losing fluid then you have a leak and would need to get it fixed and then recharged. And it isn't anitfeeze that you use for the AC. You should have the AC refrigerent recharged about every three years.

 

It takes a refrigerant.....I don't remember what one...I'd have to look in my service manual. Like tech said...its closed system so you have a leak somewhere.

 

Well, I've had my car for about 3 years and I can't remember having the AC refrigerent recharged. My car isn't leaking though. About a year ago, my AC stopped working and I took my car to Ice Cold Auto Air and they had to repair my clutch wires. It's a possiblity that is broke again. I just wanted to check the levels incase nothing's broken.

I use to take my car to Jiffy Lube and on one of the invoices they said they refilled the Anti Freeze Coolant. Is that the coolant for the engine?

 

The anti freeze coolant is what goes into your radiator

 

Why would it benefit the enfironment by having a closed unit for the AC? Don't some cars have open units? When u say open unit does that mean u can add fluids to the AC?

 

because the refrigerent that is used, though better then what they used to use(which was better because would freeze your **** off with that AC unit) is bad for the environment. And not 100% sure, but I don't thgink there are any considered open units by law. A closed unit means you can't just drain and add. very easily anyways.

 

FYI......you can buy refrigerant service cans at walmart or autoparts stores. it is recommended (by law) that you have it drained or repaired at a certified mechanic. but if it is low then you can add some yourself it is R-134A. the kit comes with a bottle of refrigerant, a valve, and a quick connect hose with a gage on it.....the gage is very important. the car must be turned on, and when you hook it up make sure that you hook up the unit to the LOW pressure side........when you say clutch wires i hope you mean your a/c compressor clutch. and if your wires broke then you wouldn't have to check your levels........does your a/c not work or does it work and just blow hot air.

 

All units are basically sealed units. Yes there are connection points to service the system. You cannot check your level easily. You could if you have an appropriate guage set check sytem pressures. This would give you an idea what your charge is if you know what you are looking at. If not to check your level you ave to actually recover the R134 refrigerant into an EPA approved recovery machine and then you can see how much your sstem had then after checking for leaks and removing water and noncondensable gases. Then you could recharge the system with an approved machine you can put in the appropriate amount of refrigerant (should be on your hood via a sticker) and do not add a coupla ounces thinking it will help. Modern R134 suck just as bad with 2 extra or 2 missing onces. So you need a good scale to measure your charge. So whether you can buy the can of R134 at the store or not (Suppose to still need a card to buy, not policed well at all) it is best to have it professionally done as the you can't do it right at home.

Oh, watever you do---DO NOT USE R134 WITH SEALANTS---basically AC AIDS!!!

The real key is to get the air, water, and non-condensable gases out. Then put in a the correct charge. Time to visit a shop and get it done right. If you just let fly you can do more harm then good. The air and oil I think it was will combine under heat of compression in the compressor toform acid. Cool stuff.
