Should I ????
Should I disconnect the heater hoses from the heater core and run a loop? Since the heater and a/c system are not working, do you think this is a good idea or what??
Thanks for any input.

It would probably be better to put a shut off valve in the in side and open it once in a while. the two hoses are different sizes, I think. If you leave the core cut off completly it will rust eventually.

Re: Should I ???? (l2vette)
In my case, the heater core was leaking so I connected the two hoses with a 5/8 to 3/4 hose adapter I bought at NAPA. If your heater core is ok, the cutoff valve sounds like the best way to shoot coolant through there every once in a while to prevent rustout. Only caution is that your heater core could leak inside the car and mess up your carpets. Mine leaked at the hose connection under the car instead of inside.

One draw back to bypassing or eliminating the heater core is that the defrost/defog will not work. Not a major concern 99% of the time but that 1% could mean seeing out you windsheild.

Re: Should I ???? (l2vette)
I installed ball valves on both hoses that way I can open it up for the winter months and shut it off for the summer, but I do open it every now and again in the summer to keep it from rusting. It made a big diference in the cabin temperature. I got the stuff a Lowe's

Re: Should I ???? (l2vette)
I installed a heavy duty shut off valve (ball type) in the line running to the heater core. Get a good, quality one, not a garden hose type. I open mine up regularly during the summer just to keep the core flushed. I haven't had any problems and it does make the cabin a LOT cooler.
