Q & A

What's in the Box

Help your vintage engine keep cool by adding an electric cooling fan to your radiator. Electric fans are far more efficient than mechanical engine driven fans because they free up horsepower and only run when you want them to (when used with a fan controller, not included). Plus, most electric fans can be mounted ahead of the radiator or behind the radiator, with the more efficient location being on the engine side of the radiator.
These powerful electric fans work with 6-volt electrical systems and draw 6 to 10 amps, depending on the size. The fan is supplied as a "puller" to mount behind the radiator, but it can be changed to a "pusher" by reversing the wires, flipping the fan blade and mounting in front of the radiator.
  • Available in 12", 14" or 16" diameters
  • Fans have 10 straight blades
  • High impact plastic construction
  • Sealed ball bearings for long life
  • Can push or pull
  • Works with positive or negative ground systems
  • Includes mounting ears (straps not included)

For best results, be sure that your generator supplies enough current to power the fan. If it does not, check out our 6 Volt Alternator 91067169. It supplies additional current at idle to run electric accessories, unlike many factory generators. To learn more about the importance of using a fan shroud along with your cooling fan, read our tech article Radiator Cooling Performance.

Runtz 12 Volt to 6 Volt Reducers
(Part #91064101)

"Runtz" transistorized reducers allow you to use your original 6 volt electronic devices (like gauges) on a vehicle that has been converted to 12 volts. You will need a "Runtz" for each 6 volt electric gauge on your car.

Designed for 12 volt negative ground systems only. Screw type terminals. 1.5 ohm resistance, 4 amp max load, 25 watts.

910-64101 Instructions (PDF)


Note: Never, ever use ceramic block style reducers for gauges, radios or lighting. A power surge will destroy the electronics when first turned on. Ceramic block reducers should only be used to operate 6 volt DC motors and fans on 12 volt DC.

6-Volt Alternator for Wide 5/8 Inch Belt
(Part #91067168)

If you are still running the 6-volt system on your car, truck or even tractor, the generator is your weak point. Even at highway speed that old generator cannot put out enough to keep up with the lights, heater motor and radio. This alternator puts out 60 amps at 7.5 volts at highway speeds, up to 30 amps at idle, and has the regulator built in. It includes the required plug and can be installed on almost any engine by modifying or purchasing a new mounting bracket.

                        These relays are a must have when running one of our 6 volt electric fans.  
  • Heavy duty 20 amp relay
  • Will handle the start-up draw of a 6 volt motor
  • 5 terminals
  • Mounting tab
Fan/Shroud/Cooler Mounting Kit
(Part #58066643)

This mount kit consists of 4 threaded plastic bolts 3/16" diameter and approx. 8-1/2" long. Also includes 4 1/4" spacers, 8 thin washers, and 4 metal wingnuts.

Works great for mounting your fan shroud, electric fan, or oil cooler directly to your radiator.
