Sooooo, if you install a shut off valve in the hose going from the water pump to the heater core, no HOT COOLANT is getting to the heater core. If no hot coolant is getting TO the heater, NO hot coolant is coming OUT of the heater core. Therefore, a shut off valve is COMPLETELY UNNECESSARY on the heater core outlet hose. Thanks for clarifying that.

if you don't put a shutoff in both hoses, the heater core WILL get hot.

You are missing the point targeting the heater. The biggest culprit of interior heat is under chassis exhaust. Two choices, side exhaust or wrap exhaust pipes with heat insulation wrap. By the time you wrap the pipes multiple times, expect a dent in your checking account

Funny that you have mentioned wrapping the exhaust pipes. I bought (2) 50ft heat wrap off Amazon for 16$. I was only going to wrap the back half of my exhaust. That way I can protect my newly installed composite leaf springs. Looks like I'm going to go ahead and order 2 more pairs of 50ft wrap to do the rest of the piping.
