Removal and Installation
INFOID:0000000009479903
REMOVAL
1. Remove the engine under cover. Refer to
EXT-15, "Removal and Installation"
.
2. Drain engine oil. Refer to
3. Remove the oil filter using Tool as shown.
WARNING:
Be careful not to burn yourself, as the engine and engine oil
may be hot.
CAUTION:
• Oil filter is equipped with a pressure relief valve.
• Use Genuine NISSAN Oil Filter or equivalent.
• When removing, position a shop cloth to absorb engine
oil leaks or spills.
• Do not allow engine oil to adhere to drive belts.
• Completely wipe off any engine oil that adheres to the engine and the vehicle.
INSTALLATION
1. Remove foreign materials adhering to the oil filter seal mating surface.
2. Apply clean engine oil to the oil filter seal circumference of the
new oil filter as shown.
3. Screw on the oil filter manually until it touches the installation
surface, then tighten it by 2/3 turn as shown. Or tighten to speci-
fication.
4. Refill engine with new engine oil. Refer to
5. Inspect the engine for oil leaks. Refer to
.
6. Install the engine under cover. Refer to
EXT-15, "Removal and Installation"
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to
MA-16, "FOR USA AND CANADA : Fluids and Lubricants"
(United
States and Canada) and
MA-18, "FOR MEXICO : Fluids and Lubricants"
(Mexico).
• Use procedure below to check for fuel leakage.

OIL FILTER
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.

WARNING:
Be careful not to burn yourself, as the engine oil and engine coolant may be hot.
CAUTION:
• Do not spill engine coolant on the drive belt.
• Do not spill engine oil on rubber parts such as drive belts and engine mounting insulator.
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-
ing.
REMOVAL
1. Drain engine coolant from radiator and cylinder block. Refer to
CO-40, "Changing Engine Coolant"
EM-220, "Disassembly and Assembly"
NOTE:
Perform this step only when removing water pipes and hoses.
2. Remove engine front under cover. Refer to
EXT-15, "Removal and Installation"
3. Disconnect water hoses from oil cooler.

OIL COOLER
CAUTION:
Perform this step when engine is cold.
4. Remove oil filter. Refer to
LU-25, "Removal and Installation"
5. Remove connector bolt, oil cooler, and O-ring.
CAUTION:
Do not reuse O-ring.
INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing compressed air through engine coolant
inlet. If necessary, replace oil cooler assembly.
Relief Valve
Check relief valve for movement, cracks and breaks by pushing the ball. If necessary, replace relief valve.
INSTALLATION
Installation is in the reverse order of removal, paying attention to the following.
• If replacement of the relief valve is necessary, install the new relief valve in place by tapping it in using suit-
able tool.
CAUTION:
Do not reuse relief valve.
• Confirm that no foreign objects are adhering to the sealing sur-
faces of the oil cooler and oil pan (upper).
• Tighten connector bolt after aligning cutout on oil cooler with pro-
trusion on oil pan (upper) side.
CAUTION:
Do not reuse O-ring.
INSPECTION AFTER INSTALLATION
