The radiator usually cools better if the a. thermostat is stuck open. b. air dam is working properly. c. air dam is removed. d. thermostat is stuck closed.

Air Dam is working properly ( B )

Explanation:

The Radiator is a device found/attached to the Engine of the car. it is usually filled up with water or coolant and its major function is to keep the engine cool below a specific temperature.

The Air Dam is found at the lower part of the front bumper while the Radiator is also found in the Engine usually at the Front bumper. the Air Dam allows minimal air to go under the car to help cool the engine as well. The thermostat regulates the flow of coolant between the engine and radiator but if left stuck open or stuck closed will not help the radiator function well because thermostat is meant to open and close at different engine temperatures
