Ecotec Engine Noise in Cab
Just purchased a 2008 G6 sedan with Ecotec engine and 39k miles. I drove a dozen or more G6's before selecting this one and we have lots of Ecotec powered cars in the family fleet. The engine seems to "roar" which is most noticeable on acceleration from the driver's seat. Noise level from other positions in the vehicle is not too bad. The sound quality is normal for this vintage Ecotec, but its abnormally loud. Sounds as if there is a sound insulation panel missing someplace or perhaps an air duct is disconnected.
Does this sound familiar to anyone?
Is there a panel that goes under the dash on the driver's side to isolate the engine noise? If so, mine is missing.
The engine hood insulation and all the rubber around the edge of the engine compartment appears to be in place.
How do the dash vent directional vanes come out. (will they break if I pull too hard)?
Thanks in advance
