The valve pictured is from the = RX7.  The connections have been changed from the original configuration and = soldered to the core.  This valve works to adjust the flow through the core = but wouldn’t be a reliable cutoff for safety purposes.  Ball = valves on the engine side of the firewall for both the supply and return would = probably be a better arrangement.  Either valve could be used for making = adjustments, but the supply valve would probably be preferred.

 

I have two small muffin fans in the = glareshield which blow air from under the glareshield onto the windshield.  = There is no heated air supply from the heater core to these fans.  So far, = that arrangement has worked fine.  The humidity here is usually quite = low, however.
