W124, freon issue.
I have a 1992 300ce, and i dont know what type of freon or where it should be put in from, nor the pressure.
Could anyone guide me to a good type of freon, where to put it and at wut pressure Thank you |

I humbly suggest that you simply take it to a shop and pay them. It is not as simple as buying the freon and putting it in. It also can be dangerous, high pressure gas, if you don't know what you are doing.
Highly likely that you have an R-12 system. You can't buy it unless you pass a test on the Internet, Federal Law. Why waste your time. You need to find out where your leak is. A shop will put in dye and try to find the leak. If it's your compressor, or evaporator then it's a task far about your tool and skill set.

He's right. If you have no clue about how to do this, you're gonna learn the hard way - and by that, I mean it's going to cost you a pile to fix what you did wrong.
You probably have R12, take it to an independent. First question is: why do you have no freon in the system? And once the leak is found (using a "sniffer" is the best way - garages have them), then you can fix the leak and refill the system.

Ditto the above.
I just had Enrique "top off" the freon on my 300CE. He did it while the car was in for a scheduled service and front brake pads. You really do need specialized equipment to do the job right. Incidentally, I just found out that the front brake pads for the 300CE are more expensive than the ones for the 300TE. Dang it!

I agree with the previous replies, that it may be best to have a specialist look at it if you aren't familiar with A/C work.
BTW, my '92 300CE uses R-134a; I think the M104 engined cars were changed over first in NA. To find out which Freon you have, mercmike, just look at the top of the upper radiator crossmember in your engine compartment. It will have one of two placards on it, specifying which you have. Pictures attached.

First if he went out and bought one of those wally world 134 kits,and had a 12 system he could not hook it up! though from the sound of it he dose not know enough about freon.(124). No insult intended just what I see,save yourself from a damaged compressor,take it to a pro,it may just need a slight service and a pound of freon to top it off. JNT

A note for a/c DIYers..
The R-12 Refrigerant in your autos is a CFC refrigerant [chlorofluorocarbons] The use of the word "FREON" is not a type of refrigerant, but rather the Copywrite Brand Name of refrigerants made by Dupont. Refrigerants can be from the Genetron Co and be the same R-12 HFC, but it is not Freon..it would only be Freon if it was a Dupont product CFC. This used to be a common accepted term to refer to refrigerants, mainly b/c Dupont was first to replace sulfur and ammonia as refrigerants due to their toxicity, but with all the new refrigerants on the market today, it is only used by those outside the trade..the correct term is simply Refrigerant... ..but freon will do fine here... I can remember way back when guys also just called it "GAS".. ...when a guy would come in and ask us if we could put some GAS in his a/c, we would say.. " Sure, you want HighTest or Regular????" ..
