FAQ

Q1: Is this nozzle a direct replacement for the original Bosch DLLA156SM058?
Yes, this nozzle is manufactured to match the exact specifications of the Bosch DLLA156SM058 (OE 9 432 610 644). It is a 100% brand-new, direct replacement part that requires no modifications for installation. It fits standard Bosch injection holders and is compatible with engines originally using this nozzle type.

Q2: What is the recommended installation procedure?
Installation should be performed by a qualified diesel technician. Ensure the injector body and nozzle seat are clean before fitting. Tighten the nozzle retaining nut to the manufacturer’s specified torque (typically 60-80 Nm for S-Type nozzles, but verify with your engine manual). After installation, check for leaks and test the injection pressure to ensure proper operation. Always use new copper washers or seals if required.

Q3: How should I store and maintain this nozzle if not used immediately?
Store the nozzle in its original packaging in a clean, dry environment at room temperature (15-25°C). Avoid exposure to moisture, dust, or extreme temperatures. For long-term storage, consider applying a light anti-rust oil to the nozzle tip. Before installation, inspect the nozzle for any signs of damage or contamination and clean with diesel fuel if necessary.
