I have a 2008 G6 3.5 L. It's loosing antifreeze. My brother replaced the hose and water pump. It's still dripping antifreeze in several spots but in the same area which is the right side where the passenger tire is and near the front of the car. It drips after I drive the car and then stops after I turn the car off and car sits for awhile. It is also spraying antifreeze on the side of the engine and around where the belt in the right side of the car. I've found little puddles of antifreeze on top of the black case that houses the air filter with spray Mark's as well on the right side of the car. I constantly smell antifreeze. Temp gage remains normal but I have to keep filling the reservoir after driving the car. Any ideas please???
