●Clean excess engine coolant from engine.
FLUSHING COOLING SYSTEM
1. Fill radiator and reservoir tank with water and reinstall radiator cap.
2. Run engine and warm it up to normal operating temperature.
3. Rev engine two or three times under no-load.
4. Stop engine and wait until it cools down.
5. Drain water.
6. Repeat steps 1 through 5 until clear water begins to drain from radiator.
Checking Cooling SystemELS000JW
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.
Wrap a thick cloth around the cap and carefully remove it by turning it a quarter turn to allow built-up
pressure to escape and then turn the cap all the way off.
CHECKING COOLING SYSTEM HOSES
Check hoses for improper attachment, leaks, cracks, damage, loose connections, chafing and deterioration.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as follows.
●Be careful not to bend or damage the radiator fins.
●When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape the harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surfaces once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downward.
●Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm2 , 71 psi) and keep distance more than 30 cm
(11.8 in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
CHECKING RADIATOR CAP
1. Pull the negative pressure valve to open it and check that it
close completely when released.
●Check that there is no dirt or damage on the valve seat of the
radiator cap negative-pressure valve.
●Check that there are no abnormalities in the opening and
closing conditions of the negative-pressure valve.
2. Check radiator cap relief pressure.
●When connecting the radiator cap to the tester, apply engine
coolant to the cap seal part.

ENGINE MAINTENANCE (QR20DE·QR25DE)
●Replace the radiator cap if there is an abnormality in the negative-pressure valve, or if the open-valve
pressure is outside of the standard values.
CHECKING RADIATOR SYSTEM FOR LEAKS
To check for leakage, apply pressure to the cooling system with a
tester.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure engine coolant escaping
from the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
Checking Fuel LinesELS000JX
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration. If nec-
essary, repair or replace faulty parts.
Fuel Hose Clamp
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is
3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
Changing Air Cleaner FilterELS000JY
VISCOUS PAPER TYPE
The viscous paper type filter does not need cleaning.
DRY PAPER TYPE
It is necessary to clean the filter or replace it at the recommended intervals, more often under dusty driving
conditions.Testing pressure:

AIR CONDITIONER COMPRESSOR BELT
1. Remove RH splash cover (with undercover attached).
2. Loosen idler pulley lock nut (A).
3. Turn adjusting bolt (B) to adjust.
●Refer to MA-26, "Checking Drive Belts" .
4. Tighten lock nut (A).
ALTERNATOR AND WATER PUMP BELT
1. Loosen adjusting lock nut (C).
2. Loosen alternator fixing bolts (D) (each on front and rear).
3. Turn adjusting bolt (E) to adjust.
●Refer to MA-26, "Tension Adjustment" .
4. Tighten nut (C) and bolt (D) in this order.
Changing Engine CoolantELS000CD
WARNING:
●To avoid being scalded, never change the engine coolant when the engine is hot.
●Wrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn
to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
1. Open radiator drain plug at the bottom of radiator, and remove
radiator cap.
●Be careful not to allow engine coolant to contact drive
belts.
●Cover the exhaust tube heat shield to prevent from splashing
engine coolant.Nut A:

2. Open drain plug on cylinder block and air relief plug.
3. Remove reservoir tank, drain engine coolant, then clean reser-
voir tank.
4. Check drained engine coolant for contaminants such as rust,
corrosion or discoloration.
If contaminated, flush engine cooling system. Refer to MA-29,
"FLUSHING COOLING SYSTEM" .
REFILLING ENGINE COOLANT
1. Install reservoir tank, radiator drain plug and cylinder block drain plug.
●Apply sealant to the thread of cylinder block drain plug.
Use Genuine Liquid Gasket or equivalent.
2. Fill radiator slowly with engine coolant until engine coolant spills
from the air relief plugs, then install air relief plugs.
CAUTION:
If the filling rate is too fast, this could lead to air being
mixed in the engine coolant. Be sure to fill the engine cool-
ant slowly according to the rate indicated above.
●Replace the copper washer of the air bleeding plug.
●Use genuine Nissan anti-freeze engine coolant or equiva-
lent mixed with water (distilled or demineralized).
Refer to MA-16, "
RECOMMENDED FLUIDS AND LUBRICANTS".
●Pour engine coolant through engine coolant filler neck slowly of less than 2 (1-3/4 lmp qt) a
minute to allow air in system to escape.

3. Fill reservoir tank to specified level.
4. Warm up engine to normal operating temperature without radia-
tor cap installed.
●If engine coolant overflows radiator filler hole, install
radiator cap.
5. Run engine at 3,000 rpm for 10 seconds and return to idle speed
with radiator cap installed.
●Repeat two or three times.
Watch engine coolant temperature gauge so as not to overheat
the engine.
6. Stop engine and cool down to less than approximately
50°C(122°F).
●Cool down using a fan to reduce the time.
●If necessary, refill radiator up to filler neck with engine coolant.
7. Refill reservoir tank to MAX level line with engine coolant.
8. Repeat steps 5 through 7 two or more times with radiator cap installed until engine coolant level no longer
drops.
9. Check cooling system for leaks with engine running.
10. 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.
11. If sound is heard, bleed air from cooling system by repeating steps 5 through 7 until engine coolant level
no longer drops.
●Clean excess engine coolant from engine.
FLUSHING COOLING SYSTEM
1. Fill radiator with water until water spills from the air relief hole, then close air relief flag. Fill radiator and
reservoir tank with water and reinstall radiator cap.
