What exactly is the pipe that i have circled called? How does it come out after taking bolt out? Can I buy one? If so, where? I work at advance auto parts and could not find it through any of our sources. I technically don't need a new one because I'm taking the upper thermostat housing off and a bracket on that pipe is in the way. I didn't really want to take the 2 bolts with male torx heads out in case they stripped. Anyways, any help would be appreciated.
