i posted a thread earilier about the smell of antifreeze. i'm now driving the car more and now i am smelling the antifreeze when the car is running. i do not smell it from the heater only when i have the window down and when i am stopped. my friends dad has not looked at it but he thinks it is a head gasket. if it was the head gasket wouldn't there be coolent mixed in with the oil? i have no idea what it could be. i changed the water pump and it is not leaking from that. what do you think it could be than.
