I drive my car untill the snow flies and heat is required some of those days, however I noticed the amount of heat generated in the cabin from the heater box with just coolant flow is pretty high.

For the hot summer days I'd like to put a ball valve inline on the supply side.

Any downside to this? Anyone try it?
 
Ya would like to see how all that's done .what i do is join the 2 heater hoses with a flushing T,no coolant in the cabin.
 
Sounds like you need to pull the box and put new rubber on the flaps and or adjust cables properly. my 2cents
 
No problem doing that. Heater only early Mopars did not have a water valve, but A/C cars did. It was vacumm controled, but a manual valve will be fine.
 
Box was rebuilt and cables adjusted previously, I used foam tape for door seals as the kit wasn't around when I did it but the foams held up ok.

I've seen some nice manual shut off valves in the earls plumbing sections at speed shops I may look at.
 
Funny, I usually don't check out this section of the forum. This past weekend the heater core in my daily driver blew. I took one of my heater hoses and looped it back to the engine and zip-tied the other one out of the way. The hose from the manifold went into a devise that blocks it off to help with cold starts, so it didn't go all the way to the heater core. A valve would look better, just be sure to block the one coming from the waterpump so you don't make the core handle too much pressure.
