Burning Coolant Smell - Help!!!
#22
I would guess the third hose you mentioned is the one missing. Anyway... FOUND the leak! The expansion tank has two pinhole leaks from the bottom half of the tank. When the system is at operating temp and press, there are twin tiny streams of coolant spraying out from the tank against the spring tower housing. Already ordered a replacement tank, plus the missing bleed/vent hose, upper and lower rad hoses and a thermostat. Looks like a project day coming up!

Finally figured it out... on the 4.2L the expansion tank has a factory plugged nipple next to the one that connects to the small hose to the T-stat housing - nothing is supposed to hook up to the blanked nipple. Anyway, found my leak... micro crack in the expansion tank. Replaced it and all is well for now - upper&lower hose, plus T-stat and housing replacement is next. The octopus looks good. Thanks again for your input!
