Product Description

Diesel Exhaust Fluid (DEF) is a urea-based fluid designed to reduce NOx emissions. Because of increasingly stringent vehicle emissions standards, most new diesel vehicles require a DEF system to remain compliant. When servicing your DEF system, it's critical to use the correct pumping and handling equipment, otherwise you risk expensive catalyst or DEF injector failures. And because DEF contains urea, which can form crystals that creep through joints and seals of poorly-designed equipment, precise engineering is required when designing DEF pumps. CARDONE direct-fit, plug-and-play DEF pumps are a reliable and complete solution to a worn or malfunctioning factory unit.

  • Real-world tested for functionality and performance
  • Quiet operation
  • Direct plug-and-play design
  • All necessary installation hardware included

What is a core?

A core is a used automotive part that is returned to the remanufacturer instead of being scrapped.

Why return cores?

Cores are literally at the “core” of the remanufacturing process, because they are the raw material used to start the remanufacturing process. That’s why remanufacturers buy cores back from customers, and they pay the most for good quality cores. If a core has too much damage in key areas, it may be unusable or require extra resources to process; therefore a reduced core payment may be awarded. This core policy explains potential deductions that may be taken from the core price if certain components are missing or damaged.

What is remanufacturing?

Remanufacturing is the process of taking used parts, completely disassembling and thoroughly cleaning them, replacing the worn components with original quality components, and restoring them to their original function. Every unit is 100% tested to ensure O.E. performance.

Why “reman”?

Reman captures used, durable goods like auto parts and puts them “back on the road” to new and sometimes better than new performance. Reman provides the opportunity for detection of common failure modes and incorporation of design improvements to prevent repeat failure.
Reman products cost consumers about 40% less than new. Reman products are one of the few “green” products that actually costs less than their “non-green” counterparts.
Reman saves up to 86% of the energy required to build a new unit. Reman realizes Greenhouse Gas savings of up to 25 lbs. per unit over new. Reman saves up to 85% of the raw material required to produce a new unit by reusing existing products. Reman is even more sustainable than recycling, as product castings are preserved rather than melted down to raw material, saving energy and reducing emissions.
