Product Description
Upgrade your 2004.5-2007 5.9L Cummins to genuine OE performance with the Cummins 4036054 Turbo Wastegate Control Solenoid (Air Control Valve). This factory-original unit is built to Cummins specifications to deliver precise boost management, optimal spool-up, and long-term durability.
If you’re experiencing symptoms such as low boost pressure, excessive black smoke, or a stored DTC P0243 (wastegate solenoid) fault, this valve addresses the root cause by restoring proper wastegate actuation on the HE351CW turbocharger.
**Fitment & Application:** Designed exclusively for the 2004.5-2007 Dodge Ram 2500/3500 equipped with the 5.9L ISB engine and the Holset HE351CW turbocharger.
**Why choose genuine Cummins?** • Exact OEM part number 4036054 – no modifications, no adaptation. • Direct-fit connector, direct-fit hose ports. • Eliminates unreliable aftermarket replacements and ensures factory performance.
Cross-Reference / Alternatives: Mopar service numbers 5140305AA and 5143256AA are often referenced for the same function on the HE351CW application.
Fitment: 2004.5, 2005, 2006, 2007 Dodge Ram 2500 / 3500 with 5.9L Cummins engine.
Installation Tip: Unmount the old solenoid from the turbo housing bracket, label and inspect all vacuum/boost hoses and replace any brittle lines. Clear any stored codes after installation and verify commanded vs actual boost reading post-install.
