Probally needs Intake Gaskets and a very common problem.Put a pressure pump on it to make sure.

you need to pressure test the system. Common areas to check= waterpump, hoses, radiator- especially the front of the tank directly opposite the upper hose, intake manifold(V6) and check the passenger side floorboard(heater core leaks)and check the oil for coolant . and you may have cylinder head or gasket problems, with this you normally have a very white exhaust and rough running motor when first started cold. the rough running and white exhaust will both clear up about the same time once all the coolant is pushed from the cylinder.
