I need help identifying the name of the part where I have a major freon leak.
The previous owner's dealership could not locate the leak, but 'ole Murphy (Law) took care of it. I had the van idling in the driveway when I heard a loud humming sound coming from the engine compartment. I began turning off stuff, radio - still there, rear ac - humming gone. So in my infinite wisdom I decided to turn the rear ac back on to see if I could locate the source. It was clearly near the accumulator and battery, but I could not find it. Then a minute later I had white smoke coming from the engine. Scared the out of me. I immediately turned off the ac (front and back) and ran to the front to see what it was. Luckily, no fire, but I had a freon stream shooting out of a brass block just to the right of the wiper motor. My guess is there was a slow leak from a bad seal and when the dealership added freon back in, wha-la, the leak became bigger... much bigger. As ac systems are my weak point, I hope someone can shed some light on this block, what may have caused the leak, and what the loud harmonic humming noise was coming from it. Here are two pics of the block. The freon was streaming from under the large nut in the center. My dealership's parts department doesn't seem to understand "Sprinterease" so they just send me diagrams and I have to pick the part that I need. Any help is greatly appreciated.
