The OEM ASPFL-2337 header is a specialized component designed for use in Cummins diesel systems, where reliable fluid or exhaust routing is critical. Whether used in a coolant, exhaust, or DEF-related assembly, this header plays a key role in maintaining sealed and efficient connections within the engine’s system.

Manufactured to meet Cummins’ strict standards, the ASPFL-2337 ensures compatibility and long-term dependability across a variety of heavy-duty and industrial applications.

Key features of the OEM ASPFL-2337 Cummins header include:

  • Precision-Machined Flanges
    • Provide a tight seal with no modification required
  • Durable Alloy Construction
    • Withstands thermal and mechanical stress
  • OEM Fitment
    • Designed specifically for Cummins platforms using ASPFL-series components
  • Corrosion-Resistant Finish
    • Helps prevent wear in harsh environments
  • Mounting Compatibility
    • Matches existing brackets and tank configurations

Always verify the OEM part number (ASPFL-2337) with your system specifications to ensure proper fit and function.

This header is ideal for use in Cummins-powered equipment operating in construction, transport, or stationary applications that require consistent fluid or gas flow management.

When the DEF (Diesel Exhaust Fluid) header—also called the DEF head unit—fails, it disrupts the vehicle’s emissions control system. This can trigger a chain of warnings and system responses designed to protect the engine and ensure environmental compliance.

Here’s What Typically Happens:

  • False DEF Level Readings
    • The gauge may show empty or full inaccurately, even if the tank has the correct amount of fluid.
  • Warning Messages Appear
    • You may see alerts such as:
      • “Service DEF System”
      • “Incorrect DEF Quality”
      • “Miles Until Speed Limit” or countdown to reduced operation
  • Check Engine Light Turns On
    • The ECM logs fault codes related to DEF level, quality, or communication errors.
  • Truck May Derate
    • If the system can’t verify DEF status, the truck will gradually reduce speed to comply with emissions laws—sometimes to as low as 5 mph.
  • System Lockout (No-Start Condition)
    • In some cases, continued driving with an unresolved issue may lead to a no-start mode after multiple key cycles.

Acting quickly can help prevent a derate or shutdown.

No calibration is typically needed, but sensor data should be verified with diagnostics after installation.

Yes, issues such as exhaust leaks or incorrect sensor positioning can lead to diagnostic trouble codes and warning lights.

Signs include exhaust leakage, DEF crystallization around the dosing port, sensor fault codes, or reduced SCR efficiency.

No, it’s not recommended; OEM headers are precision-engineered for emissions compliance and should be replaced if damaged.
