Keeping a truck running cool isn't something you hear a lot about, but when it starts to get hot you'll wish you did. A radiator, a fan, and a water pump are the basic components of a cooling system. As technology has progressed, these things have gotten better-water pumps move more water, radiators cool more efficiently, and beltdriven fans have been replaced with electric units.
But what if you have a classic pickup with all of the old technology? Change it out for newer stuff! Spal has made the task of installing an electric fan setup much easier with its Dual 12-inch High Performance Fan and programmable fan controller. With these two parts and a good radiator, the temp needle will stay right where you want it.

Originally created as an OE piece for the Maserati Quattroporte, the hi-po fan unit is now available in an aftermarket unit. The fans flows more than 2,900 cubic feet per minute (cfm) and are a perfect fit for larger truck radiators. To control these fans, Spal came up with the FAN-PWM, which varies the fan speed depending on the temperature instead of just switching the fan on and off. Setting the controller is as simple as pushing a few buttons.
Spal USA's "Back in Black" project '67 Chevy C10 is just the type of truck that needs a good cooling system. We traveled to corn heaven (aka Iowa) to observe Spal outfit the truck with a new dual-fan setup and programmable fan controller to cool the blown LS1 powerplant.

What's In The Box?
The new Spal USA Dual 12-inch High Performance Fan uses one high-performance motor and one extreme-performance motor to achieve a maximum airflow of more than 2,900 cfm. This model features glass-filled nylon fan blades, a steel and aluminum casing, and is balanced internally and externally to minimize vibration.
The FAN-PWM is a programmable fan controller that allows a single Spal cooling fan to vary speed based on engine temperature, increasing fan life while decreasing underhood noise. Simply choose the "Low" 50-percent speed or a "High" 100-percent speed setting.

The Final Word

The fan setup took the '67 Chevy pickup to 2,900 cfm of cooling ability, and with the FAN-PWM the driver has total control over the flow. These products complement the radiator and keep the blown LS mill right in the proper operating temp, no matter if the truck is idling or at wide-open throttle.
