How to diagnose if my heater core isnt working properly?

i have bit warm air and changed the thermostat,but the air still not hot as it should be. but 1 of the hoses is hot and the other bottom hose is not as hot as hot the top hose that has the thermostat,so when 1 hose is hot and the other is warm is it still the thermostat problem or the heater core.if i misplaced the thermostat upside down would 1 hose be hot and the other be cooler? How to diagnose if my heater core isnt working properly?
You need to feel the two hoses at the heater core. They should feel the same. If there is a noticeable difference it's time to flush or replace the core.How to diagnose if my heater core isnt working properly?
One hose from heater has a valve on it that is probably not working.
