Melvin,

Yes, there is an o-ring in there.  They can be purchased at the dealer, not sure if the list vendors carry them.  Easy to replace.  If you pinch the lines shut before starting this procedure, you lose very little coolant - to the point that bleeding the system is not necessary.

Let me try and describe where the leak is. The heater core under the
rear seat has 2 hoses to it. These attach to a small block that has a
valve and lever on it. The valve bolts onto the housing for the rear
heater. It's leaking where the join to the plastic housing is. I don't
see a gasket in there but I've not dismantled it because the leak is
slow enough to allow me to drive the van.

Can I get a gasket? Should it have one? Could I use one of the liquid
gaskets? If so, what do you recommend, it obviously gets hot from the
coolant flowing into the heater core.

Thank you
Melvin
