Yes...Return is the top and the output is through the bottom where is should be cool going back to the engine...the pump pumps the hotter fluid to the top where it flows denser (colder) through the bottom hose...hope that make sense

yeah it does i am just having brain farts LMAO!!!
How long did you have the engine running before you checked? Because if your return is cold after idling for a bit your thermostat might have gone south(seized) Might want to have a spare gasket on hand and open the thermostat housing to check it.

It has been running for 20 minutes but the weather outside was 29 F. The top was warm and the bottom cold. No fans were running.
