Dorman Diesel (DEF) Pump 599-5966

Searching for a reliable repair solution for a failed Bosch Denoxtronic module? Until now, options for replacing that popular all-in-one heater/pump diesel exhaust fluid (DEF) supply module were limited. A new factory unit is expensive and the few available aftermarket replacements can have unresolved design flaws that may lead to premature failure. This direct replacement supply module, remanufactured at our Tier 1, IATF-cerJPGied facility in Lewisberry, Pennsylvania, offers fleet managers and owner-operators like-new quality and OE performance on specified equipment powered by Volvo HD diesel engines. DEF is an effective necessity to reduce NOx emissions in selective catalytic reduction systems, but it's also invasive and corrosive, and upon evaporation, deposits white crystals in the supply module that can cause the pump seals and ultimately the pump itself to fail. Contaminated DEF can compromise pump performance, too, and since the supply module itself is regularly exposed to vibration, dirt, temperature extremes and anything else heavy-duty hauling or off-highway work throws at it, module failures happen. When they do, the failure can force the engine into a time-consuming and costly limp or shutdown mode, requiring the replacement of the guilty supply module. Dorman's comprehensive world-class remanufacturing process produces a premium replacement unit for a reliable repair that lasts. Our skilled technicians start with quality supply cores. Visibly failed or fatigued parts are rejected, components that pass visual inspection are tested, and select components are replaced with new parts. Specialized fixtures and 3-D-printed tools ensure components are installed to proper torque. Before carefully packing each module, we use proprietary equipment to test every function against an OE unit. The finished module represents Dorman's unrivaled investment in advanced remanufacturing technology and exemplary American craftsmanship, backed by a best-in-class warranty.
