CAUTION
Prolonged and repeated skin contact with used engine oil, with no effort to remove the oil, may be harmful. Always follow these simple precautions when handling used motor oil:



Avoid prolonged skin contact with used motor oil
 
Remove oil from skin by washing thoroughly with soap and water, or waterless hand cleaner. Do not use gasoline, thinners or other solvents
 
Avoid prolonged skin contact with oil-soaked clothing
 

OIL LEVEL CHECK



See Figures 1, 2, 3 and 4

Every time you stop for fuel, check the engine oil as follows:

  1. Park the truck on level ground.
  2.  

Although it is best for the engine to be at operating temperature, checking the oil immediately after stopping will lead to a false reading. Wait a few minutes after turning off the engine to allow the oil to drain back into the crankcase.

  1. Open the hood and locate the dipstick, which is on the left side of the engine. Pull the dipstick from its tube, wipe it clean and reinsert it.
  2.

  1. Pull the dipstick out again and, holding it horizontally, read the oil level. The oil should be between the H and L marks on the dipstick. If the oil is below the L mark, add oil of the proper viscosity and classification through the capped opening on top of the cylinder head cover.
  2.  
  3. Insert the dipstick and check the oil level again after adding any oil. Be careful not to overfill the crankcase. Approximately one quart of oil will raise the level from the L mark to the H mark. Excess oil will generally be consumed at an accelerated rate.
  4.  

OIL AND FILTER CHANGE



See Figures 5, 6, 7 and 8

It may be a good idea to look under the vehicle, before starting any service procedure, to orientate yourself with the necessary components and locations.

The oil should be changed at least every 7500 miles (12,000 km) or every 6 months. Nissan recommends changing the oil filter with every other oil change; we suggest that the filter be changed with every oil change. There is approximately 1 quart of dirty oil remaining in the old oil filter if it is not changed! A few dollars more every year seems a small price to pay for extended engine life-so change the filter every time you change the oil!

The oil drain plug is located on the bottom, rear of the oil pan (bottom of the engine, underneath the truck). The oil filter is located on the right side of the engine on all models.

The mileage figures given are the Nissan recommended intervals assuming normal driving and conditions. If your truck is being used under dusty, polluted or off-road conditions, change the oil and filter more frequently than specified. The same goes for trucks driven in stop-and-go traffic or only for short distances. Always drain the oil after the engine has been running long enough to bring it to normal operating temperature. Hot oil will flow easier and more contaminants will be removed along with the oil than if it were drained cold. To change the oil and filter:


CAUTION
The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

  1. Run the engine until it reaches normal operating temperature.
  2.  
  3. Jack up the front of the truck and support it on safety stands.
  4.  
  5. Slide a drain pan of at least 6 quarts capacity under the oil pan.
  6.  
  7. Loosen the drain plug. Turn the plug out by hand. By keeping inward pressure on the plug as you unscrew it, oil won't escape past the threads, and you can remove it without being burned by hot oil.
  8.  


CAUTION
The oil will be HOT! Be careful when removing the plug, so that you don't take a bath in hot engine oil.

  1. Allow the oil to drain completely. Clean and inspect the drain plug and oil pan sealing surface. If the plug is equipped with a removable gasket, also clean and inspect it.
  2.  
  3. Using a new plug gasket, if necessary, install the drain plug and tighten to 22-29 ft. lbs. (29-39 Nm). Don't overtighten the plug; otherwise, you'll be buying a new pan or a replacement plug for stripped threads.

  1. Using an oil filter strap wrench, remove the oil filter; on Z24i and VG30 engines, use a cap-type filter removal tool. Keep in mind that it's holding about one quart of dirty, hot oil.
  2.  

If the oil filter cannot be loosened by conventional methods, punch a hole through both sides near the mounting base of the filter and insert a punch, then turn to loosen the oil filter. After the oil filter is loosened, remove it from the engine with an oil filter wrench or equivalent.

  1. Empty the old filter into the drain pan and dispose of the filter.
  2.  
  3. Using a clean rag, wipe off the filter adapter on the engine block. Be sure that the rag doesn't leave any lint which could clog an oil passage.
  4.  
  5. Coat the rubber gasket on the filter with fresh oil. Spin it onto the engine by hand; when the gasket touches the adapter surface, give it another 1 / 2 - 3 / 4 turn. Do not overtighten, or you'll squash the gasket and it will leak.
  6.  
  7. Refill the engine with the correct amount of fresh oil. See the Capacities Chart later in this section.
  8.  
  9. Check the oil level on the dipstick. It is normal for the level to be a bit above the full mark. Start the engine and allow it to idle for a few minutes.
  10.  

Do not run the engine above idle speed until it has built up oil pressure, as indicated when the oil light goes out.

  1. Shut off the engine and allow the oil to drain into the crankcase for a few minutes, then check the oil level. Check around the filter and drain plug for any leaks and correct as necessary.
