    Part is good quality replacement for GM original part PN 15055342. This crappy design by GM will eventually cause these parts to fail, luckily it is fairly easy to access and replace with the correct Heater Line Quick-Connect Release Tools. If the quick release tool is not available, the one part can be cut off and new part just slides on. Be sure to lubricate O-rings on new part before installing it.

    I thought these required the special tool to remove, just a squeeze with pliers and a push then pull motion and off it comes. I didn't pay attention to which one I needed, there is a black and a white version. The white one has a 90 degree orientation and the black one is slightly angled. I replaced the white one with this black one and had to turn the aluminum line a bit for it to pop in but it seems fine.
