DeWitts Radiator Electric Fan Upgrade Kits

If you're running a single fan on your Corvette's stock radiator, then it's time to upgrade to DeWitt's aluminum electric dual Spal fan kits. These cooling systems are designed to move a massive amount of air when needed—the fan speed increases as temperatures rise. At the programmed upper threshold temperature, the primary fan speed reaches 100 percent and the secondary fan kicks in to help. As the temperature drops down, the secondary fan cycles off, and the primary slows, giving you a constant cooling temperature. You get uncompromised cooling under all driving conditions.

CSF KING Cooler Radiators

CSF KING Cooler radiators will crown your vehicle with the ultimate cooling performance. Through advanced features and heat-transfer technology, the universal KING Cooler units can be used in different types of racing and on-road vehicles. Possibilities include everything from Go-Kart to drag racing, short course, off-road, even industrial/agricultural use, or for auxiliary heat exchanger needs. CSF KING Cooler radiators feature their exclusive B-tube technology that is stronger and lighter than traditional "O" shaped tubes that are welded. Features include: * 3.5 inch 2-row core with CSF B-tube technology * Threaded bungs accepting 1.25 inch and -16 inlet/outlet connections * Universal mounting brackets included * Includes 9-inch SPAL fan * One hour hand-polished mirror finish * Specially engineered "B" shaped tubing is carefully formed and brazed over the seams to seal. The strength of this design allows CSF to utilizes thinner and lighter aluminum material for better cooling efficiency. The heat transfer surface area is increased approximately 15 percent over regular tubes. With B-tubes you are able to get "dual liquid laminar flow".

DeWitts Electric Fan Kits

DeWitts electric fan kits are high performance cooling upgrades for classic and modern cars. They complement your DeWitts aluminum radiator with SPAL electric fans (brushed or advanced brushless) and custom shrouds for superior airflow, direct fitment, and automatic temperature-controlled operation. These kits replace less efficient mechanical fans to reduce engine drag and improve performance. Most kits featu re dual fans with shrouds that provide full radiator coverage, relay wiring harnesses, and temperature sensors for seamless, efficient cooling. Key features: * High performance fans: Utilize SPAL's durable and powerful fans (brushed or brushless) for massive airflow (CFM) * Custom shrouds: Aluminum shrouds with air pressure relief flaps ensure maximum core coverage and airflow efficiency * Direct fit: Designed to bolt onto stock radiators or DeWitts Direct Fit radiators for easy installation * Automatic control: Includes wiring harnesses with relays and temperature sensors (often placed in the radiator) to automatically activate fans as needed, providing consistent cooling * Improved performance: Replacing mechanical fans frees up horsepower, reduces engine drag, and enhances cooling in all driving conditions * Types of fans: -- Brushed fans: Reliable, high-airflow fans for many applications -- Brushless (SBL) fans: More advanced, offering higher efficiency, longer life (40,000+ hours), lower noise, and precise variable speed control via PWM signals, requiring compatible controllers or smart sensors * What's included (varies by kit): -- SPAL electric fans (single or dual) -- Custom aluminum fan shroud -- Wiring harnesses with relays -- Temperature sensor -- Mounting hardware * DeWitts fan kits are a modern, complete cooling solution for classic car enthusiasts looking for reliable, powerful, and integrated engine temperature management
