0.7!(5/8 Imp qt)
4. Warm up engine to normal operating temperature without
radiator cap installed.
+If coolant overflows radiator filler hole, install filler cap.
5. Run engine at 2,500 rpm for 10 seconds and return to idle
speed with radiator cap installed.
+Repeat two or three times.
Watch coolant temperature gauge so as not to overheat the
engine.
6. Stop engine and cool it down.
+Cool down using a fan to reduce the time.
+If necessary, refill radiator up to filler neck with coolant.
7. Refill reservoir tank to Max line with coolant.
8. Repeat step 5 through step 7 two or more times with radiator
cap installed until coolant level no longer drops.
9. Check cooling system for leaks with engine running.
10. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 3,000 rpm with heater tempera-
ture controller set at several positions between COOL and
HOT.
+Sound may be noticeable at heater water cock.
11. If sound is heard, bleed air from cooling system by repeating
steps 5 through 7 until coolant level no longer drops
+Clean excess coolant from engine.
Ð FLUSHING COOLING SYSTEM ÐNLLC0108S031. Open air relief plug.
2. Fill radiator with water until water spills from the air relief hole,
then close air relief plug. Fill radiator and reservoir tank with
water and reinstall radiator cap.
3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
6. Drain water.
7. Repeat steps 1 through 6 until clear water begins to drain from
radiator.

Precautions
LIQUID GASKET APPLICATION PROCEDURENLLC00511. Use a scraper to remove all traces of old liquid gasket from
mating surfaces and grooves. Also, completely clean any oil
from these areas.
2. Apply a continuous bead of liquid gasket to mating surfaces.
(Use Genuine Liquid Gasket.)
+For oil pan, be sure liquid gasket diameter is 4.0 to 5.0 mm
(0.157 to 0.197 in).
+For areas except oil pan, be sure liquid gasket diameter is 2.0
to 3.0 mm (0.079 to 0.118 in).
3. Apply liquid gasket around the inner side of bolt holes (unless
otherwise specified).
4. Assembly should be done within 5 minutes after coating.
5. Wait at least 30 minutes before refilling engine oil and engine
coolant.

System CheckNLLC0054WARNING:
Never remove the radiator cap when the engine is hot; serious
burns could be caused by high pressure 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 HOSESNLLC0054S01Check hoses for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.
CHECKING RADIATORNLLC0054S02Check 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 sur-
rounding 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 ver-
tically 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 radia-
tor.
4. Blow air into the back side of radiator core vertically downward.
+Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm
2,71
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 CAPNLLC0054S03To check radiator cap, apply pressure to cap with a tester.
Radiator cap relief pressure:
Standard
78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)

Pull the negative pressure valve to open it.
Check that it closes completely when released.
+Check the radiator cap negative pressure valve for contamina-
tion or damage to the valve seat.
+Move the negative pressure valve to check for abnormalities to
the opening/shutting operation.
CAUTION:
+Be sure to perform the inspections after cooling down the
engine.
+Before connecting the radiator cap to the tester, apply
water or LLC to the cap sealing.

of the standard range.

CHECKING COOLING SYSTEM FOR LEAKSNLLC0054S04To check for leakage, apply pressure to the cooling system with a
tester.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
+Higher than the specified pressure may cause radiator
damage.
+Be sure to perform the inspections after cooling down the
engine.
+Use a hose adapter between the cap tester and filler neck
to prevent the radiator filler neck from deforming.
+If any abnormalities are found, repair or replace the malfunc-
tioning parts.
Water Pump
REMOVAL AND INSTALLATIONNLLC0055CAUTION:
+When removing water pump assembly, be careful not to
get coolant on drive belt.
+Water pump cannot be disassembled and should be
replaced as a unit.
+After installing water pump, connect hose and clamp
securely, then check for leaks using radiator cap tester.

REMOVALNLLC00561. Remove the undercover, splash cover (right), and accessory
belt.
2. Drain engine coolant. Refer to LC-59, ªChanging Engine Cool-
antº.
3. Support the bottom of the oil pan with a floor jack etc., and
remove the right engine mount bracket (front side of the
engine).
4. Remove the water pump pulley.
+Loosen the pulley bolts after fixing the pulley using a screw-
driver etc.
5. Remove engine mount brackets.
6. Remove the water pump.
INSPECTIONNLLC0057+Check for rust and contamination adhering to the water pump
and vane.
+Turn the pump shaft by hand, and check that the pump turns
smoothly without looseness.
INSTALLATIONNLLC0058+Install the parts in the reverse order of removal.
+Install the water pump pulley with the front mark (painted white,
used to prevent errors during assembly) facing the front of the
engine. Refer to the figure above.
