You can shut the water off in the summer to reduce the heat flow into the cab or manually adjust the amount of water that will flow through the heater core to get that just right temperature for the desired fan speed.
The valve isn't absolutely necessary to run a heater it is just a way to regulate the water flow through the heater core.

Take your time and work over a large towel as there's tiny bits , easily lost .
Take pictures of it from various angles as it is possible to re-assemble it wrong .
if you break off some of the tabs you can solder it back to-gether .

I'm also assuming either hose can go to either tube on the Ranco.
Thanks again. I wish I woulda paid more attention to my dad when he was workin on these trucks! | | |
