Heater control valve

Yup, heater control valve. It shuts off coolant flow to the heater core when you’re running the AC so the AC gets colder

I am glad yall knew that. If it leaked on my truck i would have had to take a pic and ask, too

I know it because I’ve been considering adding that to my older trucks although I’d have to rig up a vacuum connection and control, but it would help the AC

You could always get an electric one, same wire that activates A/C clutch can activate the valve.
