I will check the mentioned hoses and tubes -the changing of intake gaskets sounds like a very good idea as there is a slight
smell of antifreeze now and then. I changed head and intake gaskets on my doughters 3.4 liter Montana and on our 94 Pontiac
Trans Sport but for the 97 3800 Grand Prix there are 2 different types according to Rockauto so maybe I have to buy both types
or wait until the intake is off. /Thanks, Jan L
