4. Install oil pressure gauge and hose (SST).
5. Start engine and warm it up to normal operating temperature.
6. Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80°C (176°F)]
If difference is extreme, check oil passage and oil pump for oil leaks.
7. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine Liquid Gasket or equivalent.
c. After warming up engine, make sure there is no leaks of engine oil with running engine.

WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine oil leakage from engine components. Refer
to LU-7, "
ENGINE OIL LEAKAGE" .
2. Stop engine and wait for 10 minutes.
3. Loosen oil filler cap and then remove drain plug.
4. Drain engine oil.
5. Install drain plug with new washer. Refer to EM-26, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.
6. Refill with new engine oil.

SAE Viscosity NumberBLS0009D
GASOLINE ENGINE

5W-30 is preferable.
If 5W-30 is not available, select the viscosity, from the chart, that
is suitable for the outside temperature range.
CAUTION:

5W-20 should only be used for QR engine models.

5W-20 is not suitable for sustained high speed driving.
Anti-Freeze Coolant Mixture RatioBLS0009E
The engine cooling system is filled at the factory with a high-quality,
year-round anti-freeze coolant solution. The anti-freeze coolant solu-
tion contains the specific solutions effective for the anti-corrosion
and the anti-freeze function. Therefore, additional cooling system
additives are not necessary.
CAUTION:

When adding or replacing coolant, be sure to use only Gen-
uine NISSAN Anti-freeze Coolant or equivalent in its quality
with the proper mixture ratio. See the examples shown
right.
The use of other types of engine coolant may damage your
cooling system.

When checking the engine coolant mixture ratio by the coolant hydrometer, use the chart below to correct
your hydrometer reading (specific gravity) according to coolant temperature.
Mixed coolant specific gravity
Unit: specific gravity
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator. Wait until the engine and radiator cool down.

ENGINE MAINTENANCE (QR20DE)

8. Warm up until opening thermostat and water control valve. Standard for warming-up time is approximately
10 minutes at 3,000 rpm.

Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
9. Stop engine and cool down to less than approximately 50°C (122°F).

Cool down using fan to reduce the time.

If necessary, refill radiator up to filler neck with engine coolant.
10. Refill reservoir tank to “MAX” level line with engine coolant.
11. Repeat steps 3 through 9 two or more times with radiator cap installed until engine coolant level no longer
drops.
12. Check cooling system for leaks with engine running.
13. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000
rpm with heater temperature controller set at several position between “COOL” and “WARM”.

Sound may be noticeable at heater unit.
14. Repeat step 13 three times.
15. If sound is heard, bleed air from cooling system by repeating step 3 through 9 until engine coolant level no
longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-81, "
CYLINDER
BLOCK" .
2. Remove air duct assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
3. Disconnect heater hose (left side of vehicle) at the position in
the figure.

Enhance heater hose as high as possible.
4. Fill radiator and reservoir tank with water and reinstall radiator cap.

When engine coolant overflows disconnected heater hose, connect heater hose, and continue filling the
engine coolant.
5. Install air duct assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
6. Run engine and warm it up to normal operating temperature.
7. Rev engine two or three times under no-load.
8. Stop engine and wait until it cools down.
9. Drain water from the system. Refer to MA-16, "
DRAINING ENGINE COOLANT" .
10. Repeat steps 1 through 9 until clear water begins to drain from radiator.
Checking Cooling SystemBLS00093
WARNING:

Do not remove radiator cap when the engine is hot. Serious burns occur from high-pressure
engine coolant escaping from radiator.Radiator drain plug:
