[V8] Kalunkakalunka booo

[Kneale Brownson]

I added ambient temperature (maybe 80 degrees F) coolant right away in the
driveway with the engine running, only to have it pour out the loose hose.
Then I shut the engine down.  It was after the engine had cooled enough for
me to dig around in there to reattach the lower hose that I then added the
coolant and let the engine warm up fully and heard the noise.
