• Main Function: This relay kit enables intelligent control through a temperature sensor. It activates the fan when the temperature reaches 185°F (85°C) and immediately shuts it off when the temperature drops to 175°F (80°C), effectively enhancing heat dissipation efficiency while reducing power consumption
• Superior Quality: The housing of this electric fan relay is made of nylon, offering excellent heat resistance to withstand the high temperatures of the engine compartment. Its copper wiring provides superior electrical conductivity while reducing heat generation, thereby extending service time
• OE Thermostat: The temperature switch provided in this kit is an OE-type unit designed for installation on the engine cylinder head or any water jacket location with a threaded interface. It must be screwed into the engine and grounded to ensure proper transmission of the temperature control signal
• Easy to Install: Our kit is equipped with a clear wiring diagram and pre-marked wires. Just connect the red wire to the positive terminal of the battery, the coffee wire to the positive terminal of the fan, the black wire to the temperature sensor, and the gray wire to the switched ignition
• Wide Application: This relay kit is specially designed for 12V systems and can carry continuous current up to 40 amperes. It can be applied to most vehicles, including SUVs, pickup trucks, vans, and light commercial vehicles. Whether it is a single-fan or dual-fan system, it can be stably driven
