what year is this vehicle 70's ? that is the last time I have seen this heater control valve. LT1 engine does not use this valve. heater core has full flow at all times.
back in those days the water pump pressure went to this valve then the return from the heater core entered the intake manifold at the rear.
Its $20. And available at O'reillys, Auto Zone, Advance

Got one on my 88 5.7 TPI
Last time I had this type heater flow valve issue was in my 1972 buick skylark 350CU... my 1984 camaro don't have one .
Yup, lots of these cars had one of those... and lots also didn't. It can be argued that it's not needed. However it does help the A/C cool a bit better on really hot days, so, not an entirely bad thing to have.

I have a heater valve from years ago that I never used I might try it to see if the air box cools better in the hot weather. I have a control valve that closes on vacuum to the head , hook up vacuum to it from the ac vacuum ball that way it will stay closed then see how much better the cooling is.
