What is this?
Hey all,
We seem to have developed a small coolant leak. It doesn’t leak any visible fluid while running, but we’ve noticed a small puddle forms about 4 hours after shutting the engine down.
The leak seems to be centered around a coupling you can see in these pictures. The coupling has a part on it that looks like a screw mechanism of some sort. Anyone know what it is or what function it serves?
Thanks for any input!
