Why Your Electric Cooling Fan Should Keep Running After You Turn Off the Key
Keep your engine protected long after the ignition turns off. Heat soak can silently damage cooling systems, cause hard hot restarts, and shorten engine life — especially in performance cars, street rods, and hot rods. Discover how the American-made Hotronics CDT-240 Cool Down Timer keeps your electric cooling fan running after shutdown to reduce trapped heat, protect vital components, extend coolant life, and improve reliability. Learn why this simple upgrade delivers smarter post-shutdown cooling, better performance, and peace of mind every time you park.
