I have a 2003 Aerio with a 2.0 engine,and no water temp gauge. I'm sure the engine running hot and this engine has the thermostat on the bottom of the radiator hose. With the engine warm The top hose is solid like its full of pressure that not flowing threw, hose is new. I also had the radiator cap open when the engine was warm to see if the coolant was moving and it was, so thermostat must be working. Any other reason or places to check for blockage?

Thanks in advance.

Also interior heater works fine
