    Unhappy Coolant Overflow tank Leak

    I just discovered that my van has a leak in the bottom of the coolant overflow reservoir , there are wires coming out here so I'm assuming this is for a sensor . I've attached a picture of where the leak is coming from.

    Just got the van and can't recall that I've checked the reservoir until now, my vans been running at half way on the temp scale and a little over when idling once warmed up. Feel pretty dumb for not noticing this until now ... there's no coolant in the overflow tank but there is coolant uner the radiator cap.

    Just got a new OEM thermostat in the mail but I need to figure this out too it would seem!

    Thanks, this novice could sure use some help.

    update: I took off the overflow tank filled it with water and if i hold the gasket against the tank the leak stops, so im assuming I can glue this seal as a temporary fix... would this be a terrible idea? Im pretty sure there is an overflow tank in a local junkyard I can pull later this week... how big of an issue is it to not have coolant in the overflow tank?
