Hey guys, new here.. my wife has an 05 Pontiac g6 and jsut a few weeks ago it started to use coolant and had to get refilled atleast once a week. I read on previous post that it could be the crossover pipe gasket.. I know it isn’t the head gasket as there isn’t any water in the oil... but every time I look for the part it doesn’t come up for an 05 g6 I believe on 06 and above ?? Does it not have one? I need help!
