TURBO STOCK REPLACEMENT HE351CW DODGE 5.9L CUMMINS 2004.5-2007

This turbo is specifically designed for the 2004.5-2007 model year 5.9L Cummins engines. It will not fit the early 2004 or 2003 model year engines due to differences in the turbine housing and exhaust manifold flange. — This BD Diesel HE351CW (part number 1045767) is a direct replacement for the stock turbo on later common rail 5.9L Cummins engines, often referred to as the "600 series" or "610 series" engines. The key identifier is the electronic wastegate actuator, which this turbo includes and is pre-set from the factory. Earlier 2003-2004 models used a different turbo (often the HE341CW) with a different mounting configuration. Always confirm your truck's build date, which can be found on the driver-side door jamb sticker, to ensure you are purchasing the correct replacement part.

This is a direct, stock-equivalent replacement turbocharger. It is designed to restore original factory performance, not to provide a significant increase in horsepower or torque over a healthy OEM turbo. — The BD Diesel HE351CW is engineered to match the specifications of the original Holset turbo. It features a 60mm compressor wheel inducer and a 68mm turbine wheel inducer, dimensions that mirror the factory unit. Furthermore, the electronic wastegate actuator is pre-calibrated to OEM boost levels. While it is a high-quality new unit that will restore performance lost from a worn or failing turbo, it is not considered a performance upgrade for making higher power levels. For that, you would need to look at larger aftermarket turbochargers.

This is a 100% brand new turbocharger, not a remanufactured unit. Because it is sold as a new part, there is no core charge required. — Unlike remanufactured options that may reuse old housings or other components from failed units, every part of this BD Diesel turbo is new. The complete rotating assembly is high-speed VSR balanced to ensure precision, reduce vibration, and promote a long service life. This new construction eliminates the hassle and expense of returning a core, saving you both downtime and the potential loss of a core deposit. It's an economical choice for replacing a worn factory turbo that may be leaking oil or struggling to build boost on a 2004.5-2007 Dodge Ram with the 5.9L Cummins engine.

This turbo kit comes complete with the necessary gaskets and hardware for installation. You should not need to purchase a separate turbo install kit. — The package for BD part number 1045767 is designed to provide everything required for a direct replacement. Included in the box are: — • The brand new HE351CW turbocharger assembly • Turbine inlet gasket (manifold to turbo) • Oil drain gasket • Assorted new mounting studs and nuts • A new V-band clamp for the compressor outlet — This ensures you have fresh, correct-fitting hardware to complete the job without sourcing small parts separately. The estimated installation time is approximately 2.5 hours for an experienced technician.

No, custom tuning is not required when installing this turbo on an otherwise stock truck. It is designed as a direct OEM replacement that works with the factory engine calibration. — The BD Diesel HE351CW is built to match the exact performance characteristics of the original turbo on your 2004.5-2007 5.9L Cummins. The included electronic wastegate actuator is pre-set at the factory to command the same boost levels as the stock unit. The airflow characteristics from the 60mm compressor and 68mm turbine wheel are also designed to align with the stock fuel map. Therefore, the vehicle's ECM does not need to be recalibrated for safe and efficient operation.

Common symptoms of a failing HE351CW turbo include a noticeable loss of power, excessive blue or black smoke from the exhaust, and audible whining or siren-like sounds from the engine bay. You may also get a check engine light with underboost or overboost fault codes. — A failing turbo can manifest in several ways. A significant drop in acceleration or towing performance, especially under load, often points to the turbo not producing sufficient boost pressure. Oily, blue-tinged smoke indicates that the turbo's internal seals have failed, allowing engine oil to leak into the compressor or turbine housing and burn. A high-pitched whistle or a grinding noise that changes with engine RPM can signal a damaged compressor or turbine wheel, often from bearing failure. If you are experiencing any of these issues on your 2004.5-2007 5.9L Cummins, this new BD replacement unit (PN 1045767) is a reliable solution to restore proper function.
