APPLICATIONS

The 1001228986S Cummins DEF Tank with Header is intended for compatible diesel vehicles and equipment equipped with a selective catalytic reduction (SCR) emissions system. Applications may vary depending on the vehicle model, engine configuration, emissions system, tank capacity, and production specifications.

FUNCTION

The 1001228986S DEF Tank with Header stores diesel exhaust fluid and incorporates a header assembly used to monitor and support DEF system operation, depending on the specific configuration. DEF is supplied to the SCR aftertreatment system, where it helps reduce nitrogen oxide emissions in diesel exhaust. Proper operation of the DEF tank and header helps support emissions system performance.

A worn, damaged, or failing DEF Tank with Header may cause symptoms such as:

• DEF leaks or visible fluid around the tank.
• DEF level readings that are inaccurate or inconsistent.
• DEF level or quality warning messages.
• SCR or aftertreatment system fault codes.
• Emissions system warnings or dashboard alerts.
• Engine power limitations associated with DEF system faults.

WHY REPLACE A DEF TANK WITH HEADER?

A damaged DEF tank or malfunctioning header assembly can interfere with DEF storage, monitoring, or delivery and may trigger aftertreatment system warnings. Depending on the vehicle, unresolved DEF system faults can lead to emissions-related performance limitations. Replacing a defective unit with a compatible 1001228986S Genuine OEM Cummins DEF Tank with Header can help restore proper DEF system operation and support the intended SCR emissions control function.
