About This HE351CW / HY35W Turbo — Dodge Ram Cummins ISB 5.9L

The Holset HE351CW and HY35W are fixed-geometry turbochargers used on the Cummins ISB 5.9L diesel engine in the Dodge Ram 2500 and 3500 from 2004.5 through 2007. This era of the 5.9L Cummins is widely regarded as one of the most capable and durable diesel powertrains ever offered in a half-ton or three-quarter-ton truck — the common-rail injection system, combined with the HE351CW/HY35W turbo, produces up to 325 horsepower and 600 lb-ft of torque from the factory with strong head-room for modification.

This replacement unit fits 2004.5–2007 Ram 2500 and 3500 trucks with the ISB 5.9L engine. Symptoms of turbo failure on this platform include oil in the intercooler, audible whine or grinding from the turbo, shaft play, and loss of boost pressure.

Why the 5.9L Cummins Turbo Fails

• Bearing wear from extended oil change intervals or dirty oil
• Seal failure from heat soak after hot shutdown without idle-down
• Compressor wheel erosion from unfiltered air (torn air filter or cracked intake boot)
• Turbine wheel damage from engine-side debris
