LEVEL CHECK
●Check if the reservoir tank engine coolant level within MIN to
MAX when engine is cool.
●Adjust engine coolant if too much or too little.
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.
Changing Engine CoolantEBS00KOH
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.
2. Open drain plug on cylinder block.
3. Remove reservoir tank and drain engine coolant.
4. Check drained engine coolant for contaminants such as rust,
corrosion or discoloration.
If contaminated, flush engine cooling system. Refer to CO-10,
"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 and reservoir tank to specified level.
●Use genuine Nissan engine coolant or equivalent in its
quality. Refer to MA-16, "
RECOMMENDED FLUIDS AND
LUBRICANTS" .
●Pour engine coolant slowly of less than 2 (1-3/4 lmp qt)
a minute to allow air in system to escape.
3. Warm up engine to normal operating temperature without radia-
tor cap installed.
●If engine coolant overflows radiator filler hole, install
radiator cap.
4. 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.
5. 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.
6. Refill reservoir tank to MAX level line with engine coolant.
7. Repeat steps 4 through 6 two or more times with radiator cap installed until engine coolant level no longer
drops.
8. Check cooling system for leaks with engine running.
9. 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.
10. If sound is heard, bleed air from cooling system by repeating steps 4 through 6 until engine coolant level
no longer drops.
●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. Cylinder block drain plug:
: 7.8 - 11.8 N·m (0.8 -1.2 kg-m , 69 - 104 in-lb)

REMOVAL
Water Pump Removal
1. Drain engine coolant. Refer to CO-9, "DRAINING ENGINE COOLANT" .
CAUTION:
Perform when the engine is cold.
2. Remove the following parts.
●Engine undercover
●Alternator, water pump and air compressor belt. Refer to EM-12, "DRIVE BELTS" .
3. Remove water pump.

CAUTION:
●Handle the water pump vane so that it does not contact any other parts.
●Water pump cannot be disassembled and should be replaced as a unit.
Water Pump Housing Removal
1. Perform step 1 and 2 of “Water Pump Removal”.
2. Remove alternator.
3. Remove oil level gauge.
CAUTION:
Plug the oil level gauge guide opening to prevent oil pan from entering foreign materials.
4. Remove bolts mounting water pipe.
5. Remove water pump housing.
Water Pipe Removal
1. Remove water pump housing.
2. Remove exhaust manifold and three way catalyst assembly. Refer to EM-24, "
