FAQ

Q1: What is the difference between this H2C turbocharger and the original Cummins part?
A: This aftermarket H2C turbocharger is manufactured to meet or exceed the specifications of the original Cummins/Holset 3523022 unit. It uses the same casting dimensions, bearing geometry, and rotating assembly specifications to ensure a direct bolt-on fit. The main difference is the price point; our unit offers OEM-equivalent performance at a significantly lower cost, making it a preferred choice for fleet maintenance and repair shops.

Q2: How can I verify that this turbocharger fits my specific Cummins engine?
A: We recommend checking your engine’s serial number or the existing turbocharger’s tag. This H2C unit is standard on Cummins ISB 5.9L (24-valve) engines found in Dodge Ram trucks from 1998.5 to 2002, as well as various industrial applications. If your engine uses a Holset HX35 or HY35, this H2C is a performance upgrade. For exact fitment, please compare the turbine housing inlet flange and exhaust outlet pattern with your original part.

Q3: What maintenance is required for this turbocharger?
A: Proper maintenance is critical for longevity. Always use clean, high-quality engine oil (API CI-4+ or CK-4) and replace the oil filter regularly. Before installation, ensure the oil supply line is clean and free of debris. It is essential to prime the turbo with oil by cranking the engine with the fuel shut-off (or disabling injection) for 15-20 seconds before starting. After installation, allow the engine to idle for 1-2 minutes before driving to ensure oil circulation. Avoid sudden engine shutdowns after hard use; let it idle for 30-60 seconds to cool the turbo bearings.
