If you have a Northstar test the coolant for exhaust gases. It's most likely a blown head gasket. All Northstars blow head gaskets sooner or later. I'd check that first before putting any money in it. HTH. -Jim

Yes most definitely!!!! Todays cars dont get the airflow they need and if the cooling fans are not working then the air flow will be limited when its need. Replace your cooling fans they do not cost that much and it could save the engine in your car!!!!
