wtf, i've worked as a tech for many years and sprayed down more then my fair shair of exhausts of all sorts and never seen it turn green. its the A/C, part of the reason they changed the color of dexcool to orange was to make it easier to decern what fluid was leaking.

 

Now what would make it randomly leak all of a sudden? It seemed to only happen that night, as my garage has never had drops of it sitting there before..

 

There a thread on this in a Ford truck forum. A guys truck had yellow/green fluid in the snow after being at idel and others had experienced the same thing....

http://www.ford-trucks.com/forums/57...m-exhaust.html

 

the man said his A/C has been DISCONNECTED for over a year and a half sooooo i would think that its not refrigerant. if it were A/C he would probably be seeing it more than just when the undercarige is packed with 10+ inches of snow. jack up your car after you drive for a little bit (go to the gas station down the road and get a red bull then do a couple pulls just for fun) and take your spray bottle or even a handful of snow and put it on the catalytic converter.

 

water on a stainless steel pipe will not turn green unless theres some other **** in the water or on the pipe. could be a treatment on the pipe or who knows. but water on a hot stainless pipe will not cause a reaction that causes it to turn green.

 

all stainless steel is coated with a layer of chromium... chromium turns green, chromium is also an ingredient in the making of cheap jewelry (the kind of jewelry that turns your skin green)

HOOK LINE AND SINKER!!!!!!!!!!!

 

x2 I think he may be right!

 

Chromium is in the steel making process, not coated as a layer on top. A layer of chromium that could rub off into the environment would be TOXIC which is illegal according to EPA standards.

 

i no what your talking about with the green. i saw it the other day on my cavalier. i took it to a car wash and was spraying under it and i sprayed the down pipe and the cat and the water had a green look to it dripping . at first i thought it was coolant because i just had a water pump put it but the coolant in gm cars is orange.

 

Quick Fluid Question - Neon Yellow/Green under Car in Snow - Toyota Forums :: Toyota Nation
just read!!

 

All that the thread you posted states is that person has a similar issue. I'm not denying the fact that it could be something on the exhaust, but it's not chromium. It's toxic. How do I know? I'm a chemist in a field that is highly involved with the steel business.

OP I wouldn't worry too much. If everything else looks fine it's probably something external from the car

 

i did a little more digging and im partially wrong. The green/yellow may not be the chromium, but there is definately a thin layer of chromium ontop of the steels surface. "The chromium content of the steel allows the formation of a rough, adherent, invisible, corrosionresisting chromium oxide film on the steel surface"
-All About Stainless Steel
As i was at work today i decided to do a little experiment for those NON BELIEVERS. as you can see, without the cup it looks just like normal water, but looking in the cup you can see the what looks to be yellow but has a bit of green in it... THIS is what you would see on the snow.

 

still wouldnt mistake that for "neon green" I would more assume that a dog had pissed in the snow.

 

Yeah i hope my exhaust doesn't end up looking like the statue of liberty

 

LOL. End this discussion now. Anybody who runs an auto repair shop, like me, gets 15 phone calls every snowstorm about a green fluid leak when they moved their car.

It's a chemical reaction between the stainless steel and snow. Here's a better explanation.

An explanation for the yellow snow under your car - The Globe and Mail

So all of you who don't think this is true are welcome to waste your money getting someone to check for a leak you don't have.

 

op says "NEON GREEN not a little bit of yellow snow, there is a huge difference.

 

ignorance is bliss, green and yellow are so close on the color spectrum. you just really want it to be A/C dont you? you not only have video proof but also a website confirming as well. the OP said he has not had his A/C hooked up for almost 2 years, he more than likely uses Dexcool, and there is obviously no power steering fluid... kind of narrows it down to brake fluid (which is also clear) or some mutant squirrel that escaped from the local nuclear power plant decided to **** under his car as a joke to watch him in astonishment as he tries to figure out how it got there.

 

I will go with this

 

noooo the squirrel just drank a bunch of monster he isnt a mutant!

 

 

All i know.. is if you spray mobil one with castrol super clean.. it turns almost neon purple ....

 

Its true. I work at a Chrysler dealer, its a yellowish/green color.

 

I would check your exhaust bearings and make sure they aren't cracked or leaking grease.

 

could it possible be blinker fluid?

 

or maybe a turbo entabulator!
