1996 Sunfire 2.2 Liter
Driving down highway, flipped the ac on, heard a pop and saw something in the rear view, looked back to see a giant cloud of smoke from what I think (haven't looked closely yet)was the high pressure hose failing and blowing out all the 134a and a lot of oil on the exhaust manifold. I immediately shut the AC off, it was on maybe 30 seconds, I doubt it ran that long, the pressure switch probably killed it sooner.
This thing lost a lot of, if not all of the oil, at least 4-6 ounces. There is oil all over the front of the engine bay. Sticker under the hood says to use gm 12345923 oil, I assume this is just a high viscosity PAG oil. But does not give the amount. Is it going to hurt anything to put in a little more rather than a little less when I replace the line and recharge?
