just for another reference there is a post on this mod in the idi tech pages. page 6 " how to improve A/C performance"
My "old air" heat and ac for my 64 gmc came with one that uses a cableI installed two of these. Yeah they are manual and I need to open the Hood. But all winter, they are turned on.
I blew the Heater core late one night cutting through the Farm land south of Sacramento. (anything to avoid Sacramento)
Good thing I had my tool bag with 2 6" Vice grips to squeeze off the 2 hoses.
Good thing about these manual shut offs in a case like this.
