The shop manual says the coolant reservoir helps to maintain the correct volume of engine coolant. I have let the van sit running for 30 minutes several times and the coolant level in the reservoir NEVER changed. The manual points to obstruction in the coolan reservoir line or a faulty radiator cap. I think after all I've spent spending a few bucks more to get a new rad cap is worth it. I'm gonna pull and inspect the reservoir hose as well. I'm approaching this for once now with "lets deal with the symptoms" rather than the backwards way and the symptoms are that the temperature gauge is not holding steady like it used to on the old high mileage engine, when the cooling fans turn OFF the van tries to stall at idle and the coolant reservoir level NEVER changes.
