175-185 Degree Car Cooling Fan Thermostat Kit 12V Sensor Relay Harness

Engine overheating is a common enemy for any vehicle running 12V electrical systems, whether daily drivers, work trucks, boats, or campers. The 175-185 Degree Car Cooling Fan Sensor Relay Harness is a universal thermostat kit that automates the cooling fan to respond precisely to engine temperature. With a turn-on at 185 degrees and turn-off at 175 degrees, it helps maintain optimal engine temperature, reduces unnecessary fan running, and protects cooling system components from excessive stress. Built with durable metal and PP parts, this kit is designed to withstand heat, corrosion, and long-term use, extending the life of your cooling circuit.

This kit is suitable for a wide range of engines and vehicles that operate on a 12V system, including cars, trucks, boats, yachts, caravans, and more. It is compatible with numerous engines listed in its specification, offering a practical retrofit for classic builds, restorations, or modern upgrades where an automatic fan control is desired. The thermostat must be grounded through the engine threads for proper operation, and the engine itself must be grounded to ensure reliable performance. When the system experiences a short-circuit current that is too large, the integrated circuit breaker will automatically open to protect the circuit.

Benefits & Tips

• Efficient cooling management: The thermostat engages the electric fan only when needed, helping prevent overheating while reducing wear from unnecessary fan activity.
• Simple retrofit for multiple platforms: Designed for 12V systems and a broad list of engines, making it a versatile solution for various vehicles and OEM setups.
• Durable, long-lasting construction: Made with high-quality metal and PP, offering heat resistance and corrosion protection to extend service life.
