Yes it is - it sounds like the thermostat is stuck closed, which is preventing the coolant from circulating. Sooner or later it's going to be an issue, and probably at an inopportune time. Change the thermostat out and get rid of a potential problem before it becomes one.

SOURCE: INSTALLED NEW WATER PUMP,STILL RUNS HOT

Just follow the big hose on top af the radiator down to where it goes into the motor,The piece it connects to is the thermostat housing,Just remove the bolts and pull it off,You will see the thermostat,Replace with new one in the same direction as the old one is setting,and bolt back together.

SOURCE: 2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

You should see if the vent near the heater core is stuck. I had that happen once. It was in the position for the AC so it wasnt pushing the heat. plusthe vaccum line that operates the valve could of broke / rotted.
