Replacing the thermostat on Chevy Venture, aka Pontiac Montana, Trans Sport, aka Oldsmobile Silhouette. And many other GM cars with 3.1 or 3.4L SFI or EFI engines. Sorry for the audio in Russian, but I don't feel like making another audio track in English enjoy the view. This job probably could be done with less parts removed but I went with removing all I could to ease the access as my van is clean and has no rust and everything comes apart really easy. Book says to remove the crosspipe which I can't see how possible without rotating the engine to the service position.
