coolant odor after bumpy trip
I was on a trip in my 06 TC that I've owned for 1.5 years w/no problems and I went over a bumpy bridge(wavy up and down non jarring)doing 60mph and after that I caught whiffs of coolant whenever I opened the window after a bump, hill or hard corner. I looked under the hood and underneath the car and there was no leaks or coolant smell. The overflow tank was down about a half inch from the line. I topped it off at home when it completely cooled off and drove it again and it still has the coolant smell after corners and bumps. The coolant level seems to be staying the same now. I checked closely around the intake manifold, water pump shaft, thermostat housing and all underneath the car. The oil has no signs of water and the overfill tank has no signs of oil in it. There's no white smoke from the tailpipes either. There's no smell coming from the a/c vents and no steamy windows like from a bad heater core .Could an air bubble have been caused by the bumpy ride causing vapor to come from the pressurized cap? It all started after those bumps. Imagine going over ocean swells in a boat. That's what it was like on this bridge . I had to slow down a lot because it was getting scary. Thanks for any help.
