• OEM / Vehicle Manufacturer: TOYOTA – Passenger & Commercial Vehicles

• Typical Applications (with HP / kW):

  • Toyota Hilux 2.5 D-4D / 3.0 D-4D (2012–2015) – 144–171 HP / 106–126 kW

  • Toyota Land Cruiser Prado 3.0 D-4D (1KD-FTV) – 173–190 HP / 127–140 kW

  • Toyota Hiace 2.5 / 3.0 D-4D – 101–150 HP / 75–110 kW

II. Vehicle / Engine Application & Technical Data

Primary Vehicle / Equipment Application: Light commercial vehicles (LCV) and SUVs powered by Toyota’s D-4D series engines (primarily 1KD-FTV and 2KD-FTV).

Engine Type: Inline-4 Common Rail Diesel, Euro 5 compliant.

Injector Technology: DENSO G3 (3rd Generation) Common Rail Solenoid Injector.

Nozzle Type: G3 S72 precision multi-hole nozzle designed for improved fuel atomization and reduced emissions in high-pressure D-4D systems.

Technical Characteristics:

• Material: Specialized high-grade heat-resistant alloy steel.

• Fuel Compatibility: Ultra-low sulfur diesel (ULSD) / Bio-diesel blends (up to B7/B20 depending on region).

• Performance Features: Features a DLC (Diamond-Like Carbon) coating on the needle to reduce friction and prevent "sticking" under high-pressure Euro 5 operation cycles.

III. Critical Technician Notes (MUST-DO)

1. Clean Installation: Use a specialized lint-free cloth and diesel-specific cleaning solvent. The G3 S72 has extremely tight tolerances; even a microscopic speck of dust can cause a needle seize.

2. Sealing Components: Always use a new copper crush washer (heat shield) and nozzle holder O-ring. Ensure the seat in the cylinder head is perfectly clean and flat.

3. Injector Mounting: Adhere strictly to Toyota/Denso torque specs. Over-torquing can distort the nozzle body, leading to internal leakage or poor spray patterns.

4. Post-Installation Testing: Verification on a professional CR test bench is recommended to confirm the "I-Art" or response time matches the required delivery maps.

5. Calibration / Coding: Critical. These injectors usually require a 30-digit QR compensation code to be programmed into the ECU to balance cylinder contribution.

6. Fuel Quality Notes: Sensitive to water contamination. Ensure the primary fuel filter and water separator are serviced simultaneously with nozzle replacement.

7. Storage & Handling: Keep the protective plastic cap on the nozzle tip until the very second it is ready to be inserted into the injector body.

8. Common Fault Symptoms: Excessive black or white smoke, "knocking" noise (diesel knock) due to poor atomization, or "limp home" mode triggered by fuel pressure deviation codes (e.g., P0087, P0093).
