5.

Install oil pressure gauge and hose [SST].

6.

After warming up engine to normal operating temperature, make sure that engine oil pressure corre-
sponding to the engine speed is produced.

NOTE:
When engine oil temperature is low, the engine oil pressure becomes high.

°

C (176 

°

F)] 

If difference is extreme, check the oil passage and oil pump for engine oil leaks.

7.

After checking, install oil pressure switch as follows.

a.

Remove old liquid gasket adhering to oil pressure switch and engine.

b.

Apply thread sealant and tighten oil pressure switch to the specification.
Use Genuine Thread Sealant or equivalent. Refer to 

GI-45, "RECOMMENDED CHEMICAL PROD-

UCTS AND SEALANTS"

 .

c.

After warming up the engine, make sure there is no leaks of engine oil with running the engine.

1.

Open oil filter installation/removal cover on engine undercover.

2.

Warm up engine, put vehicle horizontally and check for engine
oil leakage from engine components. Refer to 

LU-6, "ENGINE

OIL LEAKAGE"

3.

Stop engine and wait for 15 minutes.

4.

Loosen oil filler cap, then remove drain plug.

5.

Drain engine oil.

tions for reference only.

●

Always use oil level gauge to determine when the proper amount of engine oil is in engine.

8.

Warm up engine and check area around drain plug and oil filter for oil leakage.

9.

Stop engine and wait for 15 minutes.

2.

Using the oil filter wrench (SST), remove oil filter.

CAUTION:

●

Oil filter is provided with a relief valve.
Use Genuine NISSAN Oil Filter or equivalent.

●

Be careful not to get burned when engine and engine oil
may be hot.

●

When removing, prepare a shop cloth to absorb any
engine oil leakage or spillage.

●

Do not allow engine oil to adhere to drive belts.

●

Completely wipe off any engine oil that adhere to engine
and the vehicle.

INSTALLATION

1.

Remove foreign materials adhering to the oil filter installation surface.

2.

Screw oil filter manually until it touches the installation surface,
then tighten it by 2/3 turn. Or tighten to specification.

INSPECTION AFTER INSTALLATION

1.

Check the engine oil level. Refer to 

LU-6, "ENGINE OIL"

2.

Start the engine, and there is no leaks of engine oil.

3.

Stop engine and wait for 15 minutes.
