Is it possible that the heater hoses have been crossed? There should
be three hoses:
one comes off the manifold, then attatches to the end of the heater
valve; the second attatches to the other outlet on the valve and goes
into the passenger side of the heater; the third leaves the heater
and returns to the thermostat housing.
The one caveat is that my car has a seies V motor in a Series IV, and
there seem to be some series IV remenants in the engine compartment;
so your Series V may be a little different, but I'm sure that the
theory is the same.
