This problem is quite old in my car, and Im discussing it here for first time.
The problem is that my car has a continuous sound of "guuuuuunnnnnn....." when engine is running, whether its on idle or moving on road, this sound is always there. my engine is finely tuned, petrol setting is perfect, oil and air filter changed few weeks back, but this noise is still there, what could be the reason and what would be the solution?? its more than what we have in other cars, its quite louder....
cabin has this weird sound ........ "guuuuuuunnnnnn....."
plz help....
