FAQ

Q1: How do I confirm this nozzle fits my Toyota diesel engine?
Check the OEM number stamped on your existing nozzle. If it reads 093400-6810 or the model is DN4PD681, this part is the correct replacement. When in doubt, provide your engine number and we will assist with verification.

Q2: Is special tooling required for installation?
Yes. Injector nozzle replacement requires proper disassembly of the injector holder, a nozzle puller, and a torque wrench. Nozzles should be installed with new sealing washers and the injector opening pressure should be re-tested after assembly.

Q3: What maintenance practices extend nozzle service life?
Use clean, water-free diesel fuel, replace fuel filters at recommended intervals, and avoid contaminated fuel sources. Periodic injector testing helps detect spray degradation early and prevents poor combustion, hard starting, and increased fuel consumption.
