what would happen if I bypass this vacuum hose? It was making my car overheat. Why would it make the car overheat, and is it better to just bypass the valve/vacuum thing or to replace it. I cannot seem to find a name for the part either. The hoses go into the top of the head and into the heater core and I figured i wouldn't have any heat but the heat works fine. I have had it bypassed for a few days now and no overheating or problems with the car since, so I don't even won't to bother with another if I don't have to. SO ANY INFO on this stupid mysterious part would be grateful, thank you.
