Bosch 0445110424 Common Rail Diesel Injector (0 445 110 424) | OEM Cross-Refs 12625220 / 12650509 For Holden Colorado 2.8L & GM/Opel Applications

 

The Bosch 0445110424 (0 445 110 424) is a genuine Common Rail Diesel Injector engineered for the 2.8L Duramax/VM Motori XLD28 engine family, serving as a direct-fit replacement for Holden Colorado, Chevrolet S10, and select GM/Opel applications. This solenoid-actuated CRI injector delivers the precise fuel atomization and injection timing required to restore original engine performance, fuel economy, and emissions compliance. Backed by OEM cross-references 12625220 and 12650509, this factory-new Bosch unit eliminates the guesswork associated with reconditioned injectors, providing workshops with a reliable solution for common rail system repairs.

 

 

The 0445110424 operates as a high-pressure solenoid injector within the common rail fuel system, designed to withstand rail pressures typical of modern 2.8L turbo-diesel engines. This Bosch unit is supplied new-not remanufactured-ensuring the internal valve train, nozzle, and solenoid meet factory tolerances. Key technical identifiers include the Bosch product number 0 445 110 424, with supplementary OEM numbers 12625220 and 12650509 for cross-referencing against existing inventory. The injector includes the necessary sealing ring for installation. Workshops should note that the mounting bolts for this injector family require final tightening to 21 lb-ft (28 Nm) to prevent leaks or distortion. Compared to earlier variants like the 0445110354, this unit incorporates revisions for improved durability and spray consistency, making it the preferred service part for 2012-onwards engine builds.

 

 

This injector is specifically calibrated for the 2.8L four-cylinder turbo-diesel found in a range of GM global platforms. Primary fitments include the Holden Colorado RG (2012–2024) and the Chevrolet S10 2.8 CTDI (2012–2013) , both utilizing the XLD28 engine code. Additional compatibility extends to the Chevrolet Colorado/GMC Canyon equipped with the LWN 2.8L Duramax, as well as specific Opel models sharing the GM global architecture. For parts procurers, the critical cross-reference numbers are 12625220 and 12650509-matching these OEM codes against the old injector body is the most reliable way to confirm fitment. This Bosch injector is also listed with EAN 4047024901063 for inventory tracking, and some catalogues may reference it alongside the older 35062001F supersession number.

 

 

Replacing a high-pressure injector demands meticulous attention to cleanliness and procedure. Before installation, thoroughly clean the injector bore in the cylinder head to prevent debris from compromising the new seal. Always replace the copper sealing washer and O-rings provided with the unit-reusing old seals is a leading cause of combustion gas leakage and poor heat dissipation. The high-pressure fuel lines should be inspected for flaring damage; if removed, they must be replaced to guarantee a leak-free connection at extreme pressures. Torque the hold-down clamp to the workshop-specified 21 lb-ft (28 Nm) using a calibrated wrench. Critical for the 2.8L LWN/XLD28 engines: ECU coding is mandatory. Each Bosch injector carries an individual calibration/trim code (IQA) that must be programmed into the engine control unit using a compatible diagnostic tool. This step ensures the ECM correctly compensates for injector-to-injector manufacturing variances, directly impacting idle stability and emissions compliance.

Q1: How can I definitively confirm the Bosch 0445110424 fits my customer's vehicle?
A: Never rely on vehicle make alone. Visually verify the existing injector's body for the Bosch number 0445110424 or OEM numbers 12625220/12650509. For the Holden Colorado 2.8L, cross-check the engine code (XLD28/LWN) on the vehicle placard. When in doubt, use the VIN to query the GM parts catalogue for confirmation.

Q2: Why is ECU coding essential after fitting this new injector?
A: Each Bosch injector has a unique IQA code compensating for microscopic flow rate variations. Without programming this code into the ECU, the engine control module cannot properly adjust fuel delivery, leading to rough idle, increased emissions, and potential DTCs. Coding ensures the new injector is balanced with the other three cylinders.

Q3: Should I replace a single 0445110424 or the entire set of four?
A: For high-mileage 2.8L engines (exceeding 150,000 km), a full set replacement is advised. While a single unit resolves the immediate symptom, the remaining three injectors have accumulated similar wear. Replacing all four now prevents a return visit for another "bad injector" symptom in the near future, saving the customer duplicate labour costs.

Q4: What are the typical failure signs this injector addresses?
A: This direct replacement resolves classic common rail failure indicators: hard hot-starting (excess leak-off), a rolling/lumpy idle (imbalance), excessive black smoke under acceleration (poor atomization), and a noticeable diesel smell in the engine oil (internal leakage leading to fuel dilution).

Q5: Is this unit brand new or a reconditioned exchange part?
A: The Bosch 0445110424 as supplied here is a factory-new, genuine OEM-spec part, not a remanufactured unit. This guarantees the nozzle and solenoid are unworn, providing maximum service life and compliance with the engine's original performance calibration.
