FASTSTORM Electric Fan Relay Kit 12V 60 AMP Electric

FASTSTORM's 12V 60A electric fan relay kit is a complete, waterproof wiring and thermostat package that automatically turns a radiator fan on at 185°F and off at 175°F for dependable engine cooling.

This ready-to-install kit bundles a 60 amp relay, a 4-pin waterproof relay housing, a temperature-controlled switch, fused power lines, and a simple wiring diagram so you can convert an existing fan or replace worn cooling components quickly. Designed for single-fan setups on cars, trucks, boats and other 12V systems, the assembly emphasizes reliability in wet conditions and precise temperature-based control to reduce unnecessary fan run time.

How does this kit improve cooling performance?

The high-capacity 60A relay gives the fan full power without stressing smaller circuits, while the thermostat switch triggers the fan only when needed. That combination keeps coolant temperatures in a narrow band and reduces continuous fan operation, which improves fuel efficiency and reduces wear on the fan motor.

• 60 amp relay supports high-current fans up to typical 10"–16" sizes
• Waterproof 4-pin relay housing prevents corrosion and failure in damp environments
• Thermostat set to 185°F on / 175°F off for repeatable temperature control

What comes in the kit and how hard is it to install?

You receive all wiring, fused power leads in waterproof holders, the relay assembly and the thermostat switch plus a schematic. Installation is straightforward for anyone comfortable with basic automotive wiring: attach power to the fused lead, route ignition and relay control wires, and mount the temperature switch to the radiator or coolant passage.

• Complete wiring harness with labelled leads for +12V, ignition, relay and switch
• Waterproof fuse holders for secure power protection
• Clear wiring diagram to guide single-fan or dual-fan adaptation

Is this kit durable enough for road and marine use?

Yes—components exposed to the elements are designed to resist moisture and corrosion. The waterproof relay housing and sealed fuse holders extend service life in wet climates and protect against short circuits caused by water intrusion.

• Sealed 4-pin relay housing reduces exposure to road spray and humidity
• Robust connectors and heavy-gauge wiring for long-term reliability
• Suitable for vehicles, light trucks and many marine 12V cooling setups

Who this is for: This FASTSTORM kit suits DIY mechanics and professional installers who need an affordable, reliable way to control a single radiator or condenser fan by temperature. It’s a good match if you’re converting a mechanical clutch fan to electric, replacing a failed relay or thermostat switch, or building a custom cooling solution for street, towing, or off-road use.
