Where does freon go in a car?

Question

I dont even know where the opening is supposed to be!! Doesn it look the same on all makes and models?

Answer 1

It varies from car to car. But it goes in the low pressure side of the coolant line.

I would also say to let someone else take care of this. You don't want to mess up the system, or possible get injured.

good luck.

Answer 2

It doesn't. Freon, a DuPont trade name known generically as R-12, was banned years ago as an automotive refrigerant because of some controversial environmental concerns. Unless you have a special permit, you cannot buy or add R-12 to a vehicle's air conditioning system. It is extremely expensive now, and generally replaced by R134a. They are not compatible, meaning you cannot add R134a to a system that is currently running R-12. As far as where it goes, there are ports that are located in the air conditioner plumbing. If it is a vehicle running R-12, the port will look like an oversize threaded tire stem, if it is R134a, the port is a quick-disconnect. On both, the refill port is located on the low-pressure side of the system, and is generally the larger-diameter port. They are idiot-proof, so you can't accidentally put the refill hose on the high-pressure side. If you run the air conditioner for a few minutes, the low-pressure hoses of the system will become cold, wet, and possibly frosted over. The good news for you, though, is that since you cannot buy R-12 without a permit nor can you readily find the tools to work with it, your chances of a can of R-12 exploding in your face are non-existent. However, since you can readily buy R134a and all the tools you need to convert or refill your own vehicle's system, there is still the chance that you will hurt yourself. So, to answer your question, if you really DO need R-12, and not R134a, it goes from the mechanic's machine into your vehicle without you being involved. But frankly, the mechanic will probably recommend converting your R-12 system to R134a anyway, because it's much cheaper than refilling with R-12. I would strongly suggest that you determine what is in your system now. Vehicles built after about 1994 run R134a.

Answer 3

usually there is a little spout near your A/C Compressor, which would be the large black thing that has a belt on the end of it that says something like "A/C Compressor" or something do with A/C. it's nto all the some for every vehicle since most older vehicles will use R-12 coolant ( i think that's what it's anyway lol) but all newer vehicles (say 2000 and up; but some later 90's will use it too) use R-134a coolant, there's a big difference in the two and if you use the wrong one then the coolant will literally dissolve your A/C hoses and fry the compressor. What's the make/model/year of your vehicle?

Answer 4

Are you sure Freon and not Antifreeze?
Freon is for your A/C.
Antifreeze is for cooling your engine.

Antifreeze goes in your radiator. Up by the front grill on most cars, VW Jettas have a bubble looking reservoir.
You should have a qualified mechanic do the Freon.

Answer 5

Fallow the lines (Tubes) coming out of the AC Compressor. You should see a valve that looks like the tire air valve but slightly different. There are two kind of freons, it depends on year, make and model. You need to know which one goes in your vehicle before buying it.
Good luck!

Answer 6

taking air-conditioning and refrigeration in school. where you put the freon in is called the low-side. there are two sides to a typical systems, high and low. the low side is less pressured, it is where you add the freon. it's easy to find, from the compressor when it's running you will see the low-side sweat and is cool to the touch. the valve to add the freon is on the same lime. i hope that helps.

Answer 7

DO NOT BUY A RECHARGE KIT AND DO THIS YOURSELF BECAUSE WILL HAVE NO IDEA OF THE HIGH SIDE PRESSURE AND BY PUTTING A THERMOMETER IN THE VENTS AND READING IT WILL NOT TELL YOU IF YOU HAVE SLIGHTLY OVER-CHARGED THE SYSTEM.

HAVE A TRUSTED INDEPENDENT A/C REPAIR SHOP FIRST CHECK IF YOU EVEN HAVE FREON IN THE SYSTEM AND ONCE THAT IS DETERMINED THEY CAN PERFORM A COMPLETE A/C SYSTEM LEAK CHECK.

Answer 8

It goes it the service inlet and looks a little like a metal valve stem on a tire. only bigger. It can be in many places on different cars based on hose routing and component placement.

Answer 9

Just pay someone that is qualified to handle the stuff.

Answer 10

What kind of car is it?
