Hi
Just started the car for about 1-2 minutes of driving, after few seconds on the road while going about 15-20 mph i hear a strong "PSSSSS" sound like some pressure going out from something (thought it was the wheel), got a red Engine light over the dashboard and the car stopped.
So i have opened the hood and then i see this green liquid all over the area.
I'm guessing its the AC fluid - because now its not working on cold.

The car drives normally, there's enough oil inside + Coolant liquid is full and in the right temperature - i tried to look for ECU faults with the ELM327 but there aren't any - except the AC not throwing cold air + there is no leaking under the car.

The funny part is - i didn't even turn the AC on while driving.
What do you think?

PS - this liquid smells like Clay bar

The green color is a special dye to find leaks in the A/C system.
It has had A/C leaking problems in the past hence the green dye.
Find the leak, and fix it asap, don't wait to long, an A/C system can't stand outside air(=humidity)..

Well - i have found that the hose connection to the compressor "flew" out of its place, after the little screw that's holding it broke into half! the other half stayed on the hose itself.

Now i think it needs to be drilled out, can't find any other way.

You need a screw extractor, but most are for much bigger screws. The best I've seen (and have) are by Craftsman and sold by Sears in the USA. For example model number 450SR http://www.sears.com/craftsman-4-pc...p-00952155000P?prdNo=4&blockNo=4&blockType=G4
Or see item 370200852904 on ebay search for BOA 4 or BOA micro
You use them with a reversable variable speed drill. One end of the extractor is a left hand drill bit, the other a tapered left hand thread. In most cases the broken screw comes out with the drilling. Before oyu do anything, plog and tape over the open port, even the slightest bit of dirt will ruin the compressor. The car stopping was probably the gas being sucked into the engine and staving it of oxygen.

Thank you!
I've shoved the hose inside its place, it sits but with no pressure now - just the screw doesn't hold anything yet until i fix it.
Da*n with Fiat and their cheap parts.

BTW - what you said about the gas sucked into the engine - doe's it says that the green stuff is now inside the engine / oil??

It's most certainly a Japanese Denco compressor..

Maybe, but it's out again as well..

Well, after checking it.. you are right Denso parts (even the radiator), so i'm taking (half) my words back

The green liquid is just oil with a little fluorescein to give it the green colour and make small amounts detectable under UV light. Neither will di your engine any harm. You do need to get the aircon re-gassed professionally when you have repaied the fitting. You can't just use one of the DIY top-up kits. It needs evacuating with a vacuum pump and the correct amount of oil and gas replaced. It would be good to fit a new O-ring on the fitting that came loose, it may have beeen the cause of the earlier leak and someone over tightened the screw rather than a proper O-ring repair that would have ment de-pressursing the system. Get the correct aircon O-ring, many general purpose ones will be attacked by the gas and oil used in aircon systems.

Thank you very much for your answers friends.
I booked myself for tomorrow at the dealership garage - will update.

Don't let them try to sell you a new compressor!

But you should replace the receiver/dryer - this needs to be replaced whenever the system is opened up, or you will likely ruin the compressor in the near future - and that is expensive.

Internal moisture is the arch enemy of A/C systems and if you don't both remove all the moisture before regassing (by vacuuming the system) and replace the dryer then you could easily turn essentially the entire A/C system into scrap.

Getting it working again now is not the same thing as fixing it so that it'll still be working in 5yrs time.

A competent A/C specialist will know what's needed.
