This is possibly a dumb response, but check that your radiator cap isn't bad or too low pressure. Mine has been having that problem, it doesn't overheat, and it runs great, but after a long drive I start overfilling the overflow bottle.

i am having this same issue where coolant is pushed to the reservoir when i shut the engine off, OP. I am going through the motions to test the coolant and engine compression. the fluid in the coolant test did not change colors, thankfully...though i know there is a possibility of a hidden crack in head or block that didn't show in the test. i replaced my rad cap and it seems to be holding pressure better than before. having my injectors rebuilt because i was blowing smoke as well, probably from bad fuel. i am ordering a new thermostat, not sure what temp to get. hoping the smoke clears after i get my injectors back from the shop. if not, i think i will have the IP rebuilt, or revisit if a new head gasket is in order.. the engine had an overhaul a few owners ago, which was potentially only a few thousand miles but this is unknown.
