I know our cars don't have one.
Now, it seems to me, summers could be cooler still if I didn't have full heat going to the heater box: even if there's 1/32" of plastic door separating it from the air flowing past my a/c evaporator.
And --PLEASE correct me if I'm wrong--but the flow of coolant through the heater box is passive and not forced? That is to say, like electricity, it's a "parallel" flow circuit and not 100% of coolant has to pass through it? Whereas, for example, if you blocked a radiator hose pressure would spike.
So where I'm going with this is... would there be any problem, really, if I put in a valve with a lever and just cut off the flow going to the heater core? A brass fitting from the plumbing section, insert it in that long rubber hose that goes from the waterpump bypass to the heater core (unless... which direction does coolant flow through the heater core? I'd want to sever the inlet hose, not the outlet, although once flow ceases, cutting the outlet might actually be equally effective), turn the lever, and voila, no coolant to the heater core, no heat in my dash, and maybe observably colder air conditioning?
Good idea?
If a bad idea, why/ what might this do?
It would be a manual heater control shutoff valve-- no automated system, just when it gets colder, I'll need to remember to open it again.
