The Perma-Cool Non-Adjustable Fan Wiring Kit provides the complete electrical solution for installing an electric cooling fan in your street rod, classic car, or off-road vehicle. It includes everything needed to wire a single or dual electric fan setup with reliable relay-based control, without the complexity of adjustable thermostatic controllers.

This kit includes a 40-amp pre-wired relay, a continuously rated thermal switch (turns on at 195 degrees Fahrenheit, off at 175 degrees), a 30-amp inline fuse holder with a blade fuse, a probe-type fan switch that threads into your radiator or water neck (3/8-inch NPT thread), 15 feet of 12-gauge primary wire, and assorted crimp terminals and wire connectors. The relay and fuse block are splash-resistant for underhood mounting. All components are rated for 12-volt negative-ground electrical systems.

This wiring kit eliminates the guesswork of piecing together relays, fuses, and wiring from the parts store. The thermal switch automatically engages your fans when coolant reaches 195 degrees, providing consistent cooling without driver intervention. Installation requires mounting the fan and relay, routing the wiring, and installing the probe switch into a radiator or water neck fitting — about 1 hour for most vehicles.

Make your electric fan installation plug-and-play. Get the Perma-Cool Fan Wiring Kit and keep your engine temperatures under control automatically.

Frequently Asked Questions

How do I verify this fan switch fits my vehicle make and model year?

Check this fan switch's listing for your year, make, model, and engine size for fitment. Most cooling parts from Atech Motorsports are direct bolt-on for 3-5 model years with OEM connectors. Measure your existing unit's core size and 1.25-1.5 inch inlet-outlet diameters before ordering. Verify all hose and wiring connections match to avoid fabrication work during installation. This fan switches controls your electric cooling fan operation automatically. These fan switches are rated for reliable automatic fan control.

What cooling capacity does this fan switch provide for my daily driver?

This fan switch provides 18,000 to 36,000 BTUs of capacity depending on size with 12-16 fins per inch. A 2-row or 3-row core with 1.0-to-1.5-inch tube spacing maximizes heat rejection under load. At 90 degrees ambient, this fan switch keeps coolant 15-25 degrees cooler than a degraded factory part. Sustained 5,500 RPM operation needs 2,000 to 3,000 CFM of airflow from your fan system. This fan switches controls your electric cooling fan operation automatically. These fan switches are rated for reliable automatic fan control.

Does this fan switch include a warranty covering defects and premature failure?

This fan switch has a 1-2 year warranty on materials and workmanship covering seam leaks and seal failure. Damage from improper installation, impacts, or wrong coolant types is excluded from coverage. Atech Motorsports backs this cooling part with a limited warranty needing proof of purchase. Register within 30 days online and keep your receipt for any warranty claims. This fan switches controls your electric cooling fan operation automatically. These fan switches are rated for reliable automatic fan control.

Can this fan switch handle high-boost turbocharged engines reliably without failing?

This fan switch handles boosted engines up to 650 horsepower with proper fan shrouding and airflow. The core is pressure-tested to 35-50 PSI, above the 15-20 PSI of boosted cooling systems. Welded aluminum or brazed brass construction withstands 0-to-250-degree thermal cycling without cracking. For track use above 700 horsepower, consider a triple-pass core for extra cooling capacity. This fan switches controls your electric cooling fan operation automatically. These fan switches are rated for reliable automatic fan control.

What maintenance does this fan switch need to keep working efficiently?

Flush this fan switch every 2-3 years using 50/50 ethylene-glycol and distilled water to prevent internal corrosion. Inspect the core and fins yearly for debris that reduces heat transfer by up to 30 percent. Check hose clamps at 5-7 ft-lbs and replace the cap below 13-16 PSI rating. This maintains your fan switch at peak efficiency throughout its service life in your vehicle. This fan switches controls your electric cooling fan operation automatically. These fan switches are rated for reliable automatic fan control.

Will this fan switch improve cooling compared to my failing original part?

This fan switch outperforms worn factory parts by 20 to 30 percent with improved core and fin design. Factory units degrade as passages clog and corrosion reduces surface area for heat transfer. This replacement uses a 2-row or 3-row core versus 1-row OEM, adding 1-2 quarts of coolant volume. Expect temperatures 10-20 degrees lower under heavy load or towing conditions with this part. This fan switches controls your electric cooling fan operation automatically. These fan switches are rated for reliable automatic fan control.
