Re: 1984 k20 A/C Help.
I bought a cable operated heater control valve that I plan to have completely close off inlet flow to the heater core when the temp control is at full cold. My heater core returns to the "Cold"(passenger side) of the radiator, and it is my belief that this is what causes my 8.1 to slowly approach getting too hot when idling in the summer. I am hoping it will also help with the A/C vent temps. I am hoping I can connect the cable valve to the temperature blend door cable. the PN valve that I have bought to try out is Four Seaons 74828
