The function and purpose of Radiator.

Your vehicle has a liquid-cooled engine, and the cooling liquid needs to travel through the radiator before it can do its job. The heat produced by the combustion process gets absorbed by an ethylene glycol based liquid, and that coolant has to enter your Acura RLX radiator through the top and flow down to the bottom so that it can reduce its temperature. When it goes out through the lower hose and up to the water pump, it re-enters the engine and can now absorb more heat. Your Acura RLX depends on the constant recirculation of cooling liquid so that it can stay within the prescribed operating temperature.
