Replaced AC system Saturday, purple fluid all over e

**cascade** · 06-14-2011, 02:56 PM

Saturday I replaced my dying AC compressor with a brand new one, and replaced the dryer, condenser, and orifice tube while I was at it. Today, I noticed a burning plastic like smell coming from the air vents, so I popped the hood and noticed that everything was soaked in a purple fluid. I took a photo of some of it soaked up on a cloth, does anyone know what this fluid is and how I can resolve the issue? Engine oil temp is fine, and its 105 degrees here today. AC is cold, but takes a while to get cold and ultimately isn't ice cold.

Looks like refrigerant oil. Did you make sure you tightened all nuts/bolts and use all of the supplied O-rings that came with the new compressor?

I used all the supplied O-rings, tightened everything, and even checked it for leaks with a professional-grade AC machine. It showed -30 on the gauge, and a tech told me that was indicative of no leaks.

The burnt plastic smell is odd though. Was there any squealing coming from under the hood when you smelled the odor? I am wondering if the AC clutch took a shit on ya.

No squealing. I ran the car and watched the belts turn, everything seemed fine, and I didn't see anything spraying out.

Welp...only thing you can do is have dye injected into the A/C system and check around the compressor and lines for leaks. If you have a leak...which from the pics, it looks like you do...the faulty parts will have to be replaced.

Does this system use the over pressure purge valve.......?

You need to make sure there wasn't too much oil in the system.

The way you do it is drain the old compressor oil into a measuring cup.

Only add that much oil to the new compressor.,any more and its overfull.

Thats what probable happened.

Hopefully you didn't damage the seals on the new comp.
