0445110366

Verify three stamped codes before ordering. First, the OE reference printed on the solenoid body should match the Foton OEM code E048632000009. Note that Cummins 5303101 is sometimes quoted online as an alternative - that is wrong: 5303101 is Bosch 0445120356, a 120-series injector for QSB6.7 / QSC8.3 engines, and does not interchange with 0445110366. Second, the build-plate SKU laser-etched near the electrical connector must read 0 445 110 366. Third, open the engine ECU diagnostic screen and confirm the IMA calibration code matches the variant stamped on the new injector (each F00VC01358-group injector carries a unique IMA code, mismatched IMA triggers P0201-P0204 fault codes and hard starting within 5-10 km of running). If any of the three codes fail to match, do not install - order a different SKU. Cross-check the part against the Bosch China OEM catalogue entry 0445110366 / 0433172139 / DLLA145P2139 / F00VC01358 before installation.

0445110366 uses the F00VC01358 solenoid control valve. F00VC01358 is shared with at least eight sister SKUs - 0445110291, 0445110358, 0445110359, 0445110367, 0445110386, 0445110396, 0445110434, 0445110447 - but the valve alone being identical does NOT make the injectors interchangeable. Each sister SKU carries a unique IMA (Injection Quantity Adjustment) calibration code stamped on the solenoid body, and the ECU expects that exact code during the IMA learn cycle. Installing 0445110291 in a 0445110366 application will trigger P0201 cylinder-1 circuit fault plus persistent over-fueling under load - the engine will run rough within the first 10 km and throw limp-mode after 50 km. If you need a valve replacement only, swap F00VC01358 from a same-SKU donor - do NOT swap from a different SKU.

P0201 through P0204 are cylinder-specific injector circuit faults triggered by one of three root causes on the 0445110366 / F00VC01358 platform. (1) Mismatched IMA calibration code - the most common cause after a fresh install; the ECU has not yet learned the new IMA code or the code stamped on the solenoid does not match the engine map. Clear the codes with Bosch KTS 590 or ESI Tronic diagnostic tool and force an IMA re-flash; if the codes return immediately, the physical injector is wrong. (2) Solenoid coil open-circuit or short-circuit - measure resistance across the two terminals cold: 0.5-2.0 Ohm is normal, >10 MOhm means open winding (replace injector), 10 MOhm) = replace the complete injector. Short circuit (1 MOhm (any lower means the winding insulation has failed). These tests catch solenoid failures only; they do not detect nozzle wear, control-valve wear, or internal leak paths - those require a Bosch EPS 815 or equivalent injector test bench.

0445110366 is rated for a 1400 bar maximum system pressure in Foton 4D24 / 4JB1 2.4-2.8L applications. Low-pressure feed must be 4-6 bar at the transfer pump. Symptoms of incorrect pressure: rail pressure drops below 1500 bar under load means either a worn F00VC01358 control valve or a partially clogged DLLA145P2139 nozzle - replace both as a set, do not attempt to clean the nozzle in-situ (the 6-hole 0.2139mm geometry is too tight for field cleaning and risk of asymmetric holes is high). High-pressure side test point is the banjo fitting on the rail end - use a 17 mm flare nut wrench, not an open-ended wrench, to avoid rounding the fitting.

Mechanical installation is straightforward for a competent technician, but ECU re-flash for IMA calibration requires Bosch diagnostic equipment (KTS 590, KTS 970, or ESI Tronic) and access to the Bosch China OEM catalogue. Mechanical steps: depressurise the fuel system (crank engine with fuel-pump relay removed until it stalls, then crank 5 more seconds), disconnect battery negative, disconnect injector electrical connector, remove 17 mm injector retainer bolt, pull injector with the OEM slide-hammer tool (do NOT pry with screwdrivers - body damage is not repairable). Install new copper sealing washer and O-rings, lubricate O-rings with clean engine oil, torque retainer to 60-80 N·m in a cross-pattern (30 N·m + final 60 N·m), prime the fuel system three times via hand pump before cranking. After mechanical install, the workshop must connect Bosch diagnostic equipment, force IMA re-flash with the calibration code stamped on the new injector, then clear P0201-P0204 codes if any remain. Plan 2-3 hours total workshop time including diagnostics.

12 months from invoice date on this listing. Warranty covers manufacturing defects in the solenoid winding, control-valve F00VC01358 assembly, and nozzle DLLA145P2139 sealing - failures that occur under normal duty (under 250,000 km, oil change intervals per manufacturer). Warranty explicitly excludes: (1) damage from contaminated fuel (water, particulates, biodiesel blends above B20, sulfur above 50 ppm) - sediment signs on the inlet strainer void the claim; (2) incorrect installation - over-torqued retainer (>80 N·m), missing sealing washer, cross-threaded inlet, or IMA re-flash skipped; (3) use beyond rated pressure - rail pressure above 1500 bar invalidates any solenoid-related claim; (4) any attempt to disassemble the solenoid or replace individual sub-components (the assembly is matched at the factory and not field-serviceable). To file a claim, retain the installation record, the Bosch diagnostic log showing IMA code and post-install leak-down values, and a sample of the fuel if contamination is suspected.

0445110366 is rated for Euro 3 emission compliance. For Euro 4 applications on the Foton 4J28TC / 4JB1 platform use the later-production SKU with matching IMA calibration. For Euro 5 and Euro 6 emission regulations, the F00VC01358 valve group is no longer the production reference - Bosch upgraded to the F00VC01359 family (visible on 0445110313 for the Foton 4JB1 Euro 4 era) and the 0445120xxx CRIN-series injectors with F00RJ02410 for Euro 5/6 applications. Installing 0445110366 in a Euro 5/6 application is possible mechanically but will not meet the emissions test - fault codes for NOx sensor out-of-range and SCR efficiency below threshold will appear within 50-100 km of running. If the vehicle was manufactured to Euro 5/6 standards, order the matching CRIN-series injector with the F00RJ02410 valve rather than this 0445110366.
