So I was filling up tonight and when I was done as I went to pull away a loud hissing sound and visible smoke/steam was coming from my engine bay/underneath. I shut the car off and looked under saw nothing out of the ordinary. I pushed the car to a spot to check it out and under the A/C pressure sensor/hose/compressor I could see visible green fluid on the subframe and sensor itself. I couldn't really smell anything abnormal either.

Is this freon? IIRC freon is supposed to be colorless..

Any ideas?

 

suprize NOS purge!!!

really tho, i belive you have a coolant leak.

 

it's definitely not freon.

It's probably 134r or whatever, and i do think it's green.

Our coolant is a pinkish orange...

 

No I have pink coolant

It would be whatever factory fluid is. Well maybe, a body shop might have refilled it a while back.

 

hm, didnt know that. all i know is the coolant in my other cars was green. well hope its not a major problem.

 

It's the A/C system. The fluid has a neon green/yellow color to it. Not really a big deal if you don't plan on using it anytime soon. I personally left mine with no charge for like 8 months.

 

Yea, I knew it had to be something with the A/C. Just for testing I tried running the A/C. Sounded very funny and it did not get cold at all.

It's winter here now anyway, hopefully the car is gone by next summer...

 

R134 is freon.. And if it has leak detector in it, which is neon green, then it could very well be ac system leaking.

 

It's the oil they put in the compressor. Freon is colorless, you are correct.


It sounds like you have a leak.

 

freon is green and smells like complete ass, jus check you AC piping sometimes they can get holes rubed threw the soft aluminum

 

Freon is colorless and odorless.

 

Freon is a brand of refrigerant... k thx...

 

Freon/R134, whatever you want to call it.

 

and yes it is colorless but they do put the green yellow dye in it to detect leaks

 

it is not odorless lol we had a refrigerator tank get punctured in my office that **** smelled REALLY bad.. and my car that leaks R134 has the same smell when i turn the ac on

 

It's something else then. You sure you didn't fart?

 

it's not something else man.. poison control came to my office ..and said it was freon..

 

Well then my instructors lied to me.

 

it's not a huge odor but if you put enough of it in the area you'll smell it lol

 

Yeah idk, I did the process on multiple cars and never smelled anything. That was in a shop with Idk 30 bays, so maybe it was masked by other smells or something.

 

yea that probably helped being in alot of bays . but **** in our office started off as no smell
then got worse through the day.. with al lthe windows closed.. then someone opened the fridge and the smell just started pouring out lol and all there was in it was bottles of water lol

 

$10 you were trying to log your wideband through the ac pressure sensor

 

Yup.

 

Just for the record your defrost still uses your A/C in the winter, I'd get it fixed.

 

Everything is working fine, including Defrost. It doesn't interfere with my AC at all.
