If you have a Northstar it's most likely going to be the head gaskets. Especially if you're between 90,000 and 120,000 miles. Have the cooling system tested for combustion gases in the antifreeze. If present, it's not worth fixing. You'd be looking at upwards of $3500. The engine and transmission have to come out from the bottom of the car. HTH. -Jim
