I am new to this car (Acura/Honda in general) so I don't know if this is really an issue or problem. The car is not overheating, it has decent interior heat BUT the lower radiator hose remains "stone cold" - as cold as the outside temperature. The thermostat is new (OEM), the coolant has been replaced and the system evacuated of any trapped air. I plan to flush/clean the heater core to increase the interior heat, but what (if anything) is causing the lower hoe to be so cold? Any comments or suggestions will be appreciated and welcomed.
