Fully tested and calibrated to OEM specification with 12 months warranty.
4HL1, 6HL1
Hard starting; white smoke on cold start; power loss under load; diesel knock; poor fuel economy on fleet duty cycles. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector leak-back rising with high-mileage wear; nozzle wear causing over-fuelling under load; combustion gas leaks past the injector seat on hard-worked engines. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Run comparative leak-off tests across all injectors before condemning — commercial duty cycles wear sets unevenly. Clean injector seats and fit new washers on every removal. Denso injectors carry compensation data — follow the manufacturer registration procedure after fitting. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 095000-5504 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data on file.
The 095000-5504 trusted family covers 2 verified vehicle fitments across 1 makes: Isuzu. Every fitment listed is registry-verified.
095000-5504 cross-references 15 further OE numbers, including 095000-5500, 095000-5501, 095000-5502, 095000-5503, 0950005500, 0950005501, 0950005502 and 0950005503. Always match the reference etched on your failed unit's body.
