The turbocharger with OEM number 17201-E0080 is a direct replacement for the factory Garrett GT2259LS unit fitted to the Hino N04C-TK 4.0L turbo-diesel engine. This engine powers a wide range of commercial vehicles, including the Hino Dutro / 300 Series trucks, Hino Liesse II buses, and the Toyota Coaster bus.
The N04C-TK is a 4.0L inline-four turbo-diesel engine producing approximately 140-180 horsepower and 420 Nm of torque. The turbocharger is driven by exhaust gases from the engine, spinning a turbine wheel that drives a compressor wheel to force more air into the combustion chambers. This increases volumetric efficiency, allowing more fuel to be burned and producing significantly more power and torque than a naturally aspirated engine of the same displacement.

- Garrett GT2259LS - Factory OE Specification: Manufactured to the GT2259LS specification - the same Garrett unit supplied to Hino and Toyota for the N04C-TK engine.
- Internal Wastegate with Factory Calibration: Features an internal wastegate with factory-set actuation pressure of 1.100-1.170 bar for correct boost pressure regulation.
- Water-Cooled Bearing Housing: Reduces operating temperature of turbocharger bearings and extends service life.
- Precision-Machined Compressor and Turbine Wheels: Ensures consistent boost delivery across the engine's operating range.
- Direct OE Replacement: No modifications to exhaust manifold, oil lines, or coolant lines required.
- 12-Month Manufacturer Warranty: Unlimited mileage warranty covering manufacturing defects.
- If the engine has been overhauled, it must be run-in before installing the new turbocharger
- Clean the oil feed pipe - any restriction in the oil supply will starve the turbocharger of lubrication
- Clean the oil pan - remove any sludge or debris
- Replace the engine oil, oil filter, and air filter - contaminated oil will damage the new turbocharger bearings
- Do not apply sealant to the oil hole - sealant can block the oil feed passage
| QC Item | Verification Method |
|---|---|
| High-speed VSR balancing | Each unit balanced on VSR machine to meet or exceed OEM specifications |
| Air flow calibration | Flow bench testing ensures compressor and turbine characteristics match engine requirements |
| Housing integrity | Pressure testing of turbine and compressor housings |
| Bearing clearance | Precision measurement of journal bearing clearances against OEM tolerance |
| Seal integrity | Oil and gas seal leak testing at operating pressure |
| Wastegate calibration | Actuator pressure tested - 1.100-1.170 bar specification verified |
| Full dimensional inspection | CMM measurement of all mounting points and critical dimensions |
| Symptom | Diagnosis |
|---|---|
| Loss of power under acceleration, especially uphill | Insufficient boost pressure - worn turbine or compressor wheel, or sticking wastegate |
| Excessive black smoke from exhaust | Incomplete combustion due to insufficient air - turbocharger not delivering required boost |
| High-pitched whining or screeching noise from engine bay | Worn journal bearings - imminent turbocharger failure |
| Oil consumption - blue smoke from exhaust, especially on start-up | Oil passing through worn seals into the turbine housing or intake |
| Engine warning light with boost pressure fault codes | Turbocharger overboost or underboost condition detected by ECU |
| Service Item | Interval |
|---|---|
| Change engine oil and filter | Every 5,000-10,000 km (depending on operating conditions) |
| Replace air filter | Every 20,000-40,000 km - restricted airflow increases turbocharger stress |
| Inspect oil feed and return pipes | At every oil change - check for leaks, kinks, or restrictions |
| Allow engine to idle for 30-60 seconds before shutdown | After sustained high-load driving - cools the turbocharger and prevents oil coking |
