A properly functioning cooling fan assembly is essential for preventing engine overheating, particularly during low-speed driving, idling, and stop-and-go traffic. This assembly also supports A/C condenser cooling, ensuring the air conditioning system maintains full performance. Common signs of a failing fan assembly include engine overheating, reduced A/C effectiveness, and unusual noise from the fan area near the radiator.
