Another repair on the '03 Tahoe. As is often the case older model, high mileage vehicles require frequent attention. Our last expensive repair was the engine oil leaks and a/c leak.
Well after that repair we had the truck detailed real well and handed it over to one of the kids. It's been just over a month now and here we are again.
Kid came in early saturday morning for the day and upon pulling out of our driveway late that afternoon, I heard a high pressure spraying sound and saw a fog of something coming out from under the truck, twice. I buzzed him up and told him to come on back and let's check it out. Nothing dripping and no more noise while running. Up on ramps and only saw a green liquid had sprayed on the frame and right front tire. It wasn't engine coolant. It was R-134 refrigerant and this is no time to be without A/C. I determined it was not a hose but definitely coming from the compressor. So I sent him on home in my 06 GMC and I got up early Sunday morning and got after it. I had the old one off, ran into town for a new one and back home to swap them out and got it done in right at 5 hours. I don't figure that was too bad for my first time replacing one on these LS type engines. We met half way and swapped out that afternoon. I don't care to do another one however.
The leak was apparently coming from a blow off valve located on the engine side of the compressor. It can't be seen while on the engine. So it got a new valve with compressor. All good again.
