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:
Follow the "General Precautions" before working on the fuel system. Refer to General Precaution .
WARNING:
Diesel fuel and diesel fuel vapor are 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.
WARNING:
To reduce the risk of personal injury, do not get Diesel Exhaust Fluid (DEF) in your eyes as it contains urea. In case of contact immediately flush eyes with large amounts of water for a minimum of 15 minutes. Do not swallow. In the even DEF is ingested, contact a physician immediately. Reference the Safety Data Sheet (SDS) for additional information.
WARNING:
Battery acid and battery acid fumes are extremely dangerous and can cause severe burns and explosion. To help reduce the risk of personal injury:
- Wear appropriate goggles and protective clothing.
- Always properly ventilate the area where service is being performed.
- Never allow battery fluid to come into contact with skin, eyes, fabrics or painted surfaces.
- To avoid arcing, remove the negative (-) battery cable first and attach the negative (-) battery cable last.
- If acid contacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.
WARNING:
When using compressed air for cleaning, to avoid the risk of personal injury from flying debris and dirt:
- Do not exceed 207 kPa (2.111 kg/cm 2 , 30psi).
- Wear appropriate eye protection and protective clothing including gloves.
WARNING:
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.
WARNING:
The fuel system (fuel pump, high pressure fuel lines, fuel rail, injectors) contains 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 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.
WARNING:
To avoid the risk of personal injury or fire, drain diesel fuel into an approved container and safely dispose of in accordance with the local environmental regulations.
CAUTION:
To avoid possible engine and system damage or performance issues:
- Brush away all dirt and debris from the area prior to opening any fuel, air intake, exhaust, cooling, after treatment, or other engine system.
- To avoid contamination, any open engine system ports must be closed immediately with clean care caps or an appropriate covering.
- Do not allow any debris to fall into the engine.
- Do not allow any chemical cleaners to enter the engine or any open systems during the cleaning process.
- Disconnect the battery or batteries. Refer to Battery Disconnect .
- Drain the fuel from the fuel filter housing (Stage 1). Refer to Drain .
- Remove the bolts (A) which fasten the fuel-water separator (2) to the fuel filter housing [Stage 1 (1)].
- Remove fuel-water separator.
