What’s Included?
The DCWK03 Injector Washer Kit includes the injector washers required when refitting existing injectors in the applicable Nissan Pathfinder R51 2.5L YD25 engine.
What is an Injector Washer Kit?
Injector washers help provide the required seal between the fuel injector and cylinder head.
Removing an injector disturbs the existing washer, so you should renew the appropriate washer when refitting an existing injector rather than reuse the old one.
The DCWK03 Injector Washer Kit provides the replacement washers required for the applicable Nissan Pathfinder R51 YD25 injector installation.
When Do I Need DCWK03?
Use DCWK03 when removing and refitting existing injectors, including injectors removed for testing, servicing or repair.
If you’re installing new replacement injectors, you won’t need DCWK03 because the new injectors are supplied with injector washers.

Note: Some of these application dates overlap. Do not rely on year model alone when selecting an injector or high-pressure fuel pump. Check the relevant part number and vehicle application before ordering.
Always check the individual product’s vehicle compatibility before ordering, as fuel injection components can vary depending on the model, production date and VIN.
We strongly recommend replacing all seals, washers and high-pressure injector pipes whenever injectors are removed or replaced. Reusing old components may lead to leaks, incorrect sealing or costly rework.
