Frequently Asked Questions
How do I install my fuel injector after purchasing it?
Please refer to the "Step-by-Step Installation Guide" on our product details page, which contains detailed installation instructions.
What precautions should I take before installing 0445120006 fuel injector?
The installation environment must be dust-free; lubricate the O-ring with clean machine oil before installation to prevent oil leakage; ensure the O-ring is installed correctly.
Why is my engine still unusable after replacing the fuel injector?
This is commonly due to air trapped in the high-pressure oil rail. Cycle the engine in short bursts (no more than 30 seconds) to purge air. It may take several attempts to stabilize pressure.
Is my device compatible with this part number of fuel injectors?
If unsure about compatibility, please provide your Engine Serial Number (ESN) for free verification.
How to determine if your fuel injectors need replacing?
  • Cylinder Cut-out Test: Using diagnostic software (ET), shut off cylinders one by one and observe engine speed fluctuations
  • Fuel Rail Pressure Test: Check for internal leaks preventing system pressure buildup
  • Back-leakage Test: Excessive back-leakage indicates severe wear of internal control valve assembly
  • Visual Inspection: Inspect fuel injector nozzles for carbon buildup, blockage, or corrosion
How long will it take to receive my package after payment?
Delivery time depends on your country, region, and customs clearance. Contact us with your address and postal code for shipping costs and estimated delivery time.
Step-by-Step Installation Guide
HEUI (Hydraulic Electronic Unit Injection) systems are extremely sensitive to contamination. A single speck of dust can cause premature failure.
1. Preparation
Clean the injector bores thoroughly. Ensure no carbon debris, old O-rings, or fuel/oil residue at the bottom of the seat. Inspect the injector sleeve for pitting or erosion.
2. Lubrication
Apply clean engine oil to the three O-rings and backup rings.
Warning: Never use grease. Only use clean engine oil to ensure seals slide in without tearing.
3. Seating the Injector
Push the injector down firmly by hand until you feel it "seat." Install the hold-down clamp and bolt.
4. Torque Specifications
Tighten the bolt to 30 N⋅m±7 N⋅m (22 lb-ft). Over-tightening can crack the injector body; under-tightening causes combustion gas leakage.
5. Trim Code Programming
Locate the 6-digit alphanumeric code on the top of the injector solenoid. Use ET (Electronic Technician) software to program this code into the ECM for precise fuel delivery synchronization.
Troubleshooting Guide
Issue Root Cause Solution
Black Smoke Poor spray atomization or stuck needle valve causing dripping Inspect the air filter
Hard Start Internal leakage in injector leading to insufficient starting oil pressure Inspect injector O-rings and internal seals
Engine Misfire Faulty solenoid valve coil or worn internal valve components Inspect wiring harness connections and replace damaged injectors
