I see this may be called an old post....but There is no mention of how hot . . . . . . . .

I recently took possesion of a 2002 GC with the 4.7HO engine , and just drained the coolant
after much head scrubbing. There is A LOT of informtion out here on the web, but some-of-it
is scattered. Some-no mention of drain-plugs for the engine, some-no mention of the
air-bleed plug on top of this engine, some state drain it, stick a garden hose in the radiator
fill it up and start the engine and flush till it is "clear." So I freeked when the temp guage
went "hotter than normal" after a refill and restart of the engine.
