REMOVALNJLC00561. Remove the undercover, splash cover (right), and accessory
belt.
2. Drain engine coolant. Refer to LC-44, 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.
INSPECTIONNJLC0057+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.
INSTALLATIONNJLC0058+Install the parts in the reverse order of removal.
+Install the water pump pulley with the front mark (painted white,

INSPECTIONNJLC00601. Check valve seating condition at ordinary room temperatures.
It should seat tightly.
2. Check valve opening temperature and maximum valve lift.
Standard
Valve opening temperature Above 80.5 - 83.5ÉC (177 - 182ÉF)
Valve lift More than 9 mm/95ÉC
(0.354 in/203ÉF)
3. Then check if valve closes at 5ÉC (9ÉF) below valve opening
temperature.

Changing Engine CoolantNJLC0079WARNING:
To avoid the danger of being scalded, never change the cool-
ant when the engine is hot.
Ð DRAINING ENGINE COOLANT ÐNJLC0079S011. Set air conditioning system as follows to prevent coolant from
remaining in the system.
a. Turn ignition switch ON and set temperature controller to maxi-
mum hot position.
b. Wait 10 seconds before turning ignition switch OFF.

2. Open radiator drain cock at the bottom of radiator or remove
lower radiator hose, and remove radiator filler cap to drain
coolant.
3. Remove reservoir tank, drain coolant, then clean reservoir
tank.
+Be careful not to allow coolant to contact drive belts.
4. Cover the exhaust tube heat shield to prevent from splashing
coolant.
JLC429B
SLC341B
5. Remove drain plug of cylinder block and air relief plug.
6. Check drained coolant for contaminants such as rust, corro-
sion or discoloration. If contaminated flush engine cooling
system, refer to LC-46, ªFLUSHING COOLING SYSTEMº.
7. Blow the coolant around the exhaust tube heat shield.
NOTE:
An asterisk (*1) in the figure means ªNot installed on some
modelsº.

9. Repeat steps 4 through 7 two or more times with radiator cap
installed until coolant level no longer drops.
10. Check cooling system for leaks with engine running.
11. 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.
12. If sound is heard, bleed air from cooling system by repeating
steps 4 through 7 until coolant level no longer drops
+Clean excess coolant from engine.
Ð FLUSHING COOLING SYSTEM ÐNJLC0079S031. 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.
