i think i have a dash heater control valve leaking and with temps being 102- 111 down here in good ol austin, i am not concerned for heat, so i want to shut off both valves for the heater located under the coach by motor to help out the dash air.
should i be concerned doing this as far as heat circulation, or water circulation? shut off 1 or both?
this is 2000 national with a cat 300 hp diesel pusher.
i will fix correctly for winter time IF we get any cooler weather
thanks for any help
