73 cabin heat

[Lynn S.]

It's HOT down south and even hotter in my 454/ac/auto/coup/no hot water shutoff valve. Have replaced heater/ac seals, firewall plugs etc sealed, tunnel insulation and frame foam insulaters replaced but still getting heat in the cabin.
I want to add manual shutoff valves in the 5/8" and 3/4" heater hose lines and plug the white vacuum hose coming out of the control switch. Anyone have experience with this.? Any problems? We use the heat maybe 1-2 months per year. Thanks

You don't need to put shut off valves in both hoses. If one hose is shut off the coolant can't flow.

Lynn,
Also check your weatherstripping around the doors.
When mine were replaced, there was a noticeable difference of lack of warm air coming back into the cabin near the or seams.
