FAQ

Q1: How do I confirm this nozzle fits my Mitsubishi engine?
A: Check the OEM part number stamped on your existing injector nozzle. If it reads 093400-5370 or DN0PD37, this is the correct replacement. You can also cross-reference your engine code (4D65 or 4D68) in the vehicle’s service manual.

Q2: What is the installation procedure for this injector nozzle?
A: Installation should be performed by a qualified diesel mechanic. The nozzle must be fitted into the injector holder with the correct shim thickness to achieve proper opening pressure. Always use new copper washers and torque to OEM specifications. Ultrasonic cleaning of the injector body is recommended before assembly.

Q3: How should I maintain these nozzles for maximum service life?
A: Use clean, high-quality diesel fuel and replace fuel filters at recommended intervals. Periodically test injector opening pressure and spray pattern. Contaminated fuel is the leading cause of nozzle failure — consider adding a secondary fuel filtration system for extended service in dusty or low-quality fuel environments.
