Buy Chevrolet (Chevy) Silverado 1500 Radiator Fans

Overview(Parts Geek)

The Chevrolet Silverado 1500 cooling fan assembly is a critical component in maintaining engine temperature. This assembly typically includes two electric fans-one for the radiator and another for the condenser-designed to draw air through the radiator to dissipate heat from the coolant. The fans are activated by the engine control module (ECM) based on temperature readings from the coolant temperature sensor. (AmericanTrucks, AutoZone.com)

Over time, these fans can fail due to motor wear, electrical issues, or debris interference. Symptoms of a malfunctioning fan include engine overheating, erratic fan behavior, or the fan running continuously. (GM-Trucks.com, GM-Trucks.com)
