Having problems with your 2006 Pontiac G6 ?
2007 JUST STARED LEAKING COOLANT---TOOK CAR TO A PONTIAC DEALER SAID NOTHING WAS LEAKING BUT THE CAR IS LOSING COOLANT
Is it leaking on passenger side toward front could radiator ,hose ,water pump . if it smoking white it burning coolant in cylinders head gasket. how often is it loosen coolant it not got hole in the plastic overflow container. check oil make sure not milky white .
I had the same problem with my 06 GTP... I could smell coolant, but I could not see it. In my case, it was not the head gasket of any other expensive repair, but rather this. I had a reason to replace a thermostat on this car due to subsequent stupidity (I left the pressure cap off after refilling the coolant for the umpteenth time) and then drove... This cause my coolant to boil over and then ruined my thermostat (that was the only damage), so I changed it. Strangely enough, I have had no further coolant leaks after that.
