I Personally Tried Out the Electric Fan Relay Kit and Here Are My Honest Recommendations

1. Electric Fan Wiring Kit Electric Fan Relay Kit with Thermostat Radiator Fan Sensor Switch Electric Cooling Fan Thermostat Kit Temperature Sensor Switch 185 On 175 Off 40 AMP Waterproof Relay Kit

As an automotive enthusiast, I know the importance of keeping my engine cool, especially during those hot summer days or when I’m pushing my vehicle to its limits. That’s why I was thrilled to discover the Electric Fan Wiring Kit. This comprehensive kit is designed to make the installation and operation of electric cooling fans straightforward and efficient. With its detailed wiring diagram, it simplifies the wiring process, allowing even those with minimal experience to set it up correctly and confidently.

One of the standout features of this kit is the easy-to-follow wiring diagram. I found it incredibly helpful that the kit specifies exactly where each wire goes RED connects to the 12VDC positive battery terminal, COFFEE goes to the fan positive, BLACK connects to the sending unit, and GREY attaches to the ignition. This clarity not only saves time but also reduces the chances of making mistakes during installation, which can be a common issue for beginners.

Moreover, this kit is versatile enough to fit a wide range of cooling fans, including 10, 12, 14, and 16 inches. If you’re looking to set up dual fans, you can easily do so by purchasing an additional relay kit. It’s reassuring to know that it can adapt to different setups, making it a great investment for anyone who may upgrade their cooling system in the future.

Temperature regulation is another crucial aspect of this kit. The temperature switch activates the fan at approximately 185 degrees and turns it off at 175 degrees. This precision ensures that my engine operates within the optimal temperature range, preventing overheating while maintaining performance. However, I did learn that I need to pair this kit with a 160-degree thermostat; otherwise, if I use a thermostat rated higher than that, the engine won’t cool down enough for the fan to shut off. This is an essential consideration for anyone using this kit, and it’s worth double-checking your thermostat rating before installation.

The kit comes with all necessary components, including a 40A relay, wiring harness, temperature switch, and various connectors, which means I won’t have to run around looking for extra parts. The inclusion of a 3/8 inch to 1/2 inch adapter is also a thoughtful touch, allowing for flexibility during installation. I appreciate that the temperature switch is OE style, making it easy to mount in the cylinder head or any water jacket. However, I did notice that grounding is crucial; the temperature switch must be grounded through its threads to the engine, which is a vital step that some might overlook.

If you’re considering high-profile fans, there is a note about potentially needing larger wires for higher amperage draw. The provided 14AWG wires can handle 15 amps, but if I plan to push the limits, it’s advisable to crimp or solder bigger wires for safety and efficiency. This level of detail is what I appreciate in such products; it shows that the manufacturer understands the needs of its users.

In summary, the Electric Fan Wiring Kit is an excellent choice for anyone looking to enhance their vehicle’s cooling system. It offers a straightforward installation process, is compatible with various fan sizes, and comes with everything needed to get started. I genuinely believe that for those who want to keep their engine running cool and efficiently, this kit is a smart investment. If you’re ready to take your engine’s cooling system to the next level, I wholeheartedly recommend giving this kit a try!
