23670-09590 Diesel Fuel Injector for Toyota Hiace Hilux 2KD-FTV

23670-09590 diesel fuel injector for Toyota Hiace Hilux 2KD-FTV 2.5D

The 23670-09590 diesel fuel injector is supplied by Rayfuel as an aftermarket replacement for selected Toyota Hiace and Hilux vehicles equipped with the 2KD-FTV 2.5D diesel engine. It is intended for part-number-matched common rail repair and replacement rather than selection by vehicle name alone. Diesel repair workshops, parts wholesalers and distributors can find related products in our common rail injector range.

23670-09590 diesel fuel injector identification

• Primary part number: 23670-09590
• Alternative number format: 2367009590
• Vehicle reference: Selected Toyota Hiace and Hilux applications
• Engine reference: 2KD-FTV 2.5D diesel engine
• Product type: Common rail diesel fuel injector assembly
• Product brand: Rayfuel

The numbers 23670-09590 and 2367009590 describe the same Toyota-style reference with and without punctuation; they should not be treated as two different injector specifications. Compare the complete number on the removed unit, not only the final digits. The supplied photographs show the injector body, electrical connector, fuel return connection and nozzle profile for an initial visual comparison.

Toyota Hiace, Hilux and 2KD-FTV fitment

This product is listed for selected Toyota Hiace and Hilux 2.5D applications using the 2KD-FTV engine family. Toyota diesel vehicles can use different injector versions according to model code, production period, destination market, emissions specification and engine calibration. A 2KD-FTV engine description by itself is therefore not enough to confirm fitment.

Before ordering, inspect the number on the existing injector and confirm the vehicle model, VIN or frame code, engine designation and production year. Compare the electrical connector, body shape, mounting arrangement and fuel connections with the product images. If the old injector carries a different reference, obtain a verified supersession or cross-reference before installation.

Common rail injector function and diagnosis

A common rail injector meters high-pressure diesel fuel and delivers it into the combustion chamber in response to commands from the engine control system. Correct injection quantity, timing and spray behavior support starting, stable idle, combustion balance and engine response. Wear, internal leakage, contamination or electrical faults can affect these functions, but replacement should follow proper testing rather than symptoms alone.

Common signs an injector may need checking

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

These signs do not prove that the injector has failed. Similar conditions can be caused by low rail pressure, wiring problems, contaminated fuel, poor compression, intake restrictions or other engine faults. Scan-tool data, return-flow testing, electrical checks and professional bench testing may be needed before parts are replaced.

Installation and calibration

Installation should be performed by a qualified diesel technician using clean working practices. Keep all high-pressure connections protected from contamination, inspect the injector pipe and replace required seals or washers. Follow the tightening procedure specified for the exact vehicle and engine. Some 2KD-FTV configurations may require injector compensation or calibration information to be registered with suitable diagnostic equipment, while procedures can vary by production version. Do not assume that every vehicle uses the same coding process.

Before you order

Please confirm OE number, engine model or old part photos before ordering. Verify 23670-09590 against the removed injector and confirm the Hiace or Hilux model, 2KD-FTV engine version, year and market. Toyota’s official Hilux history reference shows that the model spans multiple generations, reinforcing the need to match the exact part rather than the model name alone. Send your number and clear photos through the Rayfuel contact page if you need a fitment check.

The 23670-09590 diesel fuel injector is intended for OE-number-matched aftermarket replacement in compatible Toyota Hiace and Hilux 2KD-FTV 2.5D applications. It is sold under the Rayfuel product brand; no claim of genuine Toyota or Denso boxed origin is made.
