Gm 3.8 engine coolant leak
GM 3.8 engines are famous for coolant leaking from the intake. Sometimes though it’s really not the intake gasket. The real problem could be overlooked. Oddly enough, the belt tensioner on these engines has coolant running thru it. And the plastic tubes that route the coolant thru can quite often crack. Be sure and check this when you have a 3.8 coolant leak.
