095000-5322 Denso diesel fuel injector identification

• Primary part number: 095000-5322
• OE reference: 23670-78030
• Vehicle reference: Selected Hino / Toyota applications

Compare both 095000-5322 and 23670-78030 with the markings on the injector removed from the engine. The Denso wording used in the SEO fields describes the common rail system and buyer search reference; it does not claim that the supplied aftermarket replacement is a genuine Denso, Hino or Toyota boxed component. The product photographs show the body, connector, fuel inlet and nozzle arrangement for an initial visual comparison.

Hino and Toyota N04C application

Hino official information identifies the N04C as an approximately 4.0-liter diesel engine used in light-duty vehicles, including variants of the Hino 300 Series and Dutro. N04C engines have also been associated with selected Toyota-group commercial applications. However, an engine-family match alone does not guarantee injector compatibility because production year, market, emissions system, vehicle code and injector calibration can affect the required version.

Before ordering for either a Hino or Toyota vehicle, verify that the old injector carries 095000-5322, 23670-78030 or a confirmed replacement reference. Compare the electrical connector, high-pressure fuel connection, mounting profile and nozzle end. Do not select the part only because the vehicle is described as having an N04C engine.

Common rail injector function

A common rail injector meters and delivers pressurized diesel fuel into the combustion chamber according to commands from the engine control system. Correct fuel quantity and timing support reliable starting, balanced combustion, stable idle and normal engine response. A worn, contaminated or electrically faulty injector may interfere with these functions, but the 095000-5322 Denso diesel fuel injector should only be replaced after suitable diagnosis. Hino’s official N04C vehicle information provides a neutral reference for the engine family and its 4.009-liter displacement.

Common signs an injector may need checking

• Hard starting or extended cranking
• Rough idle or uneven cylinder contribution
• Reduced power during acceleration or under load
• Excessive exhaust smoke
• Abnormal diesel combustion noise
• Fuel leakage around the injector or sealing area
• Injector-related diagnostic trouble codes

These symptoms do not prove injector failure. Similar issues may result from low rail pressure, wiring faults, contaminated fuel, poor compression, air-intake restrictions or other engine conditions. Return-flow testing, electrical inspection, scan-tool data and professional bench testing may be required before replacement.

Installation and calibration

Installation should be completed by a qualified diesel technician. Keep all high-pressure fuel connections clean, inspect the injector pipe and replace required sealing washers or related service parts. Follow the correct tightening information for the exact engine and vehicle. Some Hino or Toyota configurations may require injector compensation or calibration data to be registered with compatible diagnostic equipment, while other versions may follow a different procedure. Confirm the applicable service process instead of assuming coding is always required.

Before you order

Please confirm OE number, engine model or old part photos before ordering. Verify 095000-5322 and 23670-78030 against the existing injector, then confirm the vehicle model, N04C engine version, production year and market. Send clear photographs and vehicle information through the Rayfuel contact page if you need compatibility support.

The 095000-5322 Denso diesel fuel injector is intended for OE-number-matched aftermarket replacement in compatible Hino and Toyota N04C 4.0L applications. Final fitment depends on exact vehicle and old-part identification.
