How does the coolant system work on a 2000 Chevy Impala?

Answer 1

Pretty much like all water cooled engines. The radiater is a pressurized heat exchanger that allows water to pass through tubes and air to pass over the tubes to transfer the heat from the water to the air. The water is pumped by a water pump through the water jackets molded into the engine block. Where the heat from the block iks transferred to the water. The water then continues back out to the radiator to be cooled again. The temperature is regulated by a thermostat located on top of the engine block and cooling fans to ensure proper airflow across the radiator for cooling.
