Dorman Diesel Exhaust Fluid Heaters
Turn off that "check engine" light and restore proper drivability with Dorman diesel exhaust fluid heaters. If your diesel vehicle is confined to a limited speed, or in power reduction mode, a common culprit may be a failed original DEF heater. These units are quality-tested to ensure a trouble-free installation, performance, and durability, helping your vehicle run smoothly. Dorman diesel exhaust fluid heaters include all necessary gaskets and O-rings for installation. They're available for a variety of car and truck applications.
