Maintenance Check

WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

When using compressed air for cleaning, to avoid the risk of personal injury from flying debris and dirt:
- Do not exceed 30psi (207 kPa).
- Wear appropriate eye protection and protective clothing including gloves.
When using high-pressure water or steam cleaning equipment, to avoid the risk of personal injury from flying debris and hot steam:
- Wear appropriate eye protection and protective clothing including gloves and a face shield.
The fuel system (fuel pump, high pressure fuel lines, fuel rail, injectors) contain very high pressure fuel. To avoid the risk of personal injury or fire:
- Do not loosen any fittings while the engine is running.
- Wait at least 10 minutes after shutting down the engine before loosening any fittings in the high-pressure fuel system to allow pressure to decrease to a lower level.
- Wear appropriate eye protection and protective equipment as high-pressure fuel spray can penetrate the skin.
- Never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Never allow diesel fuel to spill onto a hot exhaust manifold which can cause a fire.
Diesel fuel and diesel fuel vapor is flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Never allow diesel fuel to spill onto a hot exhaust manifold which can cause a fire.

Inspect the injector high-pressure supply line for leaks, cracks, damage, loose connections, chafing, or deterioration. If necessary, replace the damaged components. In addition, if injector high-pressure supply lines have visible red/orange corrosion associated with rust after rinsing debris replace the component.
