• Cooling Function: This relay kit helps maintain ideal operating temperatures by activating the fan when the engine reaches 185°F (85°C) and turning it off at 175°F (79°C). It improves cooling efficiency, keeping the engine from overheating and maintaining overall performance
• Premium Materials: The electric fan relay features a rugged plastic housing with excellent impact and wear resistance, ensuring reliable operation in harsh environments. Meanwhile, the wiring harness utilizes high-quality copper for superior electrical conductivity and long-term performance
• OE Style Thermostat: The switch that comes with this kit is an OE type and can be mounted in the cylinder head or any water jacket if desired. To ensure proper operation, the thermostat must be securely threaded to the engine to form a ground and ensure that the engine itself is grounded
• Simple Installation: This relay kit is easy to install and can be connected directly without complicated steps. Connect the red wire to the battery's positive terminal, the brown wire to the fan's positive terminal, the black wire to the ignition system, and the gray wire to the temperature sensor
• Wide Compatibility: Compatible with 12V electric cooling fans, this kit is suitable for various vehicles, including cars, trucks, and off-road vehicles. It works on a wide range of engines including 265, 283, 305, 307, 327, 350, 383, 400, 472, 502, 260, 289, 302, 351W, 347, 352, 360, 390, 406 and more
