Coolant shut off valve...
I have read about folks putting in a shut off valve on the coolant line to the heater core to help cut down the cabin heat. First, does that really work? Second, isn’t that what the vacuum controlled valve already installed is supposed to do?

I put shut off valves on both lines to heater core. Absolutely works. No circulation or back circulation at all.

I got my shut off valves at Napa. You can see the one in the top heater hose in this pic. One just like it in the bottom hose. I usually shut 'em off this time of year, and open 'em back up toward the middle of December. Missed the owne

The modern plastic replacement works much better.
Not correct. The heater cuts off when the A/C is set to MAX. It shouldn't be too hard to tinker with the vacuum system to make the heater shut off unless it's on Heat or Defrost, but I haven't had a chance to mess with it yet.
