Bosch 0445120373 Common Rail Fuel Injector for Weichai

1. Product Overview

Brand new Bosch 0445120373 common rail fuel injector (type CRIN2-16) for Weichai Power engines. The manufacturer’s technical file for this number gives OE number 610800080588; the pairing rests on that single source and is marked accordingly, while a general catalogue reading for this number range corroborates the Weichai brand direction. The OE number is printed exactly as documented: its format belongs to a special Weichai number segment and differs from the diesel range’s usual 6126…/6127… formats — that is not a misprint, and the number must not be “corrected” into those ranges. One document caution: a vehicle-match row in this number’s file carries the string 0445120426, which is the compatible number documented in 0445120372’s own file — it is template cross-talk between the two files and is NOT this injector’s compatible number. No Bosch exchange number, nozzle or control valve has been confirmed, so those fields are left blank. The neighbouring number 0445120372 is a Yuchai injector — a different maker; do not confuse the two.

2. Specifications

3. Fitment

Weichai Power engines (specific engine model to be confirmed against your old injector’s engraving — the OE pairing rests on a single technical-file source). Fitment data is for reference only — please confirm by the number engraved on your old injector or send us your VIN before ordering.

4. Cross-Reference

Note: no Bosch exchange number, compatible number, nozzle or control valve could be confirmed for this injector, so none is listed. The number 0445120426 belongs to 0445120372 as its compatible number — its appearance in this number’s file is a template error and it is not a cross for 0445120373.
