FAQ

Q1: How do I verify this nozzle fits my injector?
A: Check your injector’s Bosch part number (e.g., 0433271079) or the nozzle code printed on the old part (DLLA160S255). This S-Type nozzle is designed for standard Bosch injector holders with a 17mm hex nut. Measure the nozzle length (approx. 47mm) and diameter (6mm) to confirm compatibility.

Q2: What is the recommended installation procedure?
A: Clean the injector bore thoroughly before installation. Use a torque wrench to tighten the nozzle retaining nut to 30-35 Nm (as per engine specs). Always replace copper washers and seals. After installation, bleed the fuel system and run the engine at idle to check for leaks.

Q3: How often should I replace these nozzles?
A: Replacement intervals depend on fuel quality and engine usage, but typically every 1,500–2,000 operating hours for heavy-duty applications. Signs of wear include rough idling, black smoke, increased fuel consumption, or loss of power. Regular inspection every 500 hours is recommended.
