Hello... took my "standard heater core" to the local radiator shop for pressure test. Failed. Getting recored for $208. Question: When I hook it up, how do I route the hoses? Water pump to? Thermostat to? One of the tubes from the core is crimped and one is wide open. Can I add a manual valve in the hoses to shut off water flow to the core in the summer time? Which side of the system should it be installed?
Thanks in advance!

It really doesn't matter how the hoses are hooked up. The hoses and the header form a loop, and water will circulate through that loop as the water pump moves water through the engine. But you should have nipples attached to the motor that feed the heater, unless those have been removed.
Yes, you can add an inline manual valve to shut the water off in the summer.
