ENGINE COOLANT
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to "FLUSHING COOLING SYSTEM".
REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-242, "
Dis-
assembly and Assembly".
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air relief plug on heater hose.
4. Fill thermostat housing and reservoir tank to specified level. Refill engine coolant up to fill er neck of thermostat housing.
Pour engine coolant through engine coolant filler neck slowly of less than 2 (2-1/8 US qt, 1-3/4
Imp qt) a minute to allo w air in system to escape.
Use Genuine NISSAN Long Life Anti freeze/Coolant or equivalent mixed with water (distilled or
demineralized). Refer to MA-9, "
Fluids and Lubricants".
When engine coolant overflows air relief hole on heater hose, install air relief plug.
5. Install radiator cap.
6. Warm up until opening thermostat. 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.
7. 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 engine coolant up to filler neck of thermostat housing. Radiator drain plug:
: 1.19 N·m (0.12 kg-m, 11 in-lb)

9. Repeat steps 4 through 7 two or more times with radiator cap installed until engine coolant level no longer
drops.
10. Check cooling system for leaks with engine running.
11. 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.
12. Repeat step 11 three times.
13. If sound is heard, bleed air from cooling system by repeating steps 4 through 7 until engine coolant level
no longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank, and radiator drain plug. CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block ar e removed, close and tighten them. Refer to EM-242, "
Dis-
assembly and Assembly".
2. Remove air relief plug on heater hose.
3. Fill thermostat housing with water until water spills from the air relief hole, then close air relief plug. Fill
thermostat housing and reservoir tank with water and reinstall radiator cap.
4. Run engine and warm it up to normal operating temperature.
5. Rev engine two or three times under no-load.
6. Stop engine and wait until it cools down.
7. Drain water from the system. Refer to "DRAINING ENGINE COOLANT".
8. Repeat steps 1 through 7 until clear water begins to drain from radiator. Radiator drain plug:

REMOVAL
1. Drain engine coolant from drain plugs on radiat or and both side of cylinder block. Refer to CO-37, "Chang-
ing Engine Coolant" and EM-242, "Disassembly and Assembly".
CAUTION:
Perform this step when engine is cold.
Do not spill engine coolant on drive belts.
2. Remove engine cover with power tool. Refer to EM-169, "
Component".
3. Remove air duct (inlet). Refer to EM-173, "
Component".
4. Disconnect water suction hose from water inlet.
5. Remove water inlet and thermostat. CAUTION:
Do not disassemble thermostat.
6. Remove intake manifolds (upper and lower). Refer to EM-175, "
Component".
7. Disconnect radiator hose (upper) and wa ter hoses from thermostat housing.
8. Disconnect heater hoses from water outlet and heater pipe.
9. Remove thermostat housing, water outlet pipe, water connector, water control valve, water outlet and heater pipe.
CAUTION:
Do not disassemble water control valve.
INSPECTION AFTER REMOVAL
Make sure that valves both in thermostat and water c ontrol valve are completely closing at normal tempera-
ture.
Place a thread so that it is caught in the valves of the thermostat
and water control valve. Immerse fully in a container filled with
water. Heat while stirring. (The example in the figure shows ther-
mostat.)
The valve opening temperature is the temperature at which the valve opens and falls from the thread.
Continue heating. Check the maximum valve lift. NOTE:
The maximum valve lift standard temperature for water control
valve is the reference value.
After checking the maximum valve lift, lower the water tempera-
ture and check the valve closing temperature.
Standard values:
If the malfunctioning condition, when closing valve at nor mal temperature, or measured values are out of the
standard, replace thermostat and/or water control valve.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful not to spill engine coolant over en gine room. Use rag to absorb engine coolant.

THERMOSTAT AND WATER CONTROL VALVE
Install thermostat and water control valve with the whole circumfer-
ence of each flange part fit securely inside rubber ring. (The exam-
ple in the figure shows thermostat.)
Install thermostat with jiggle valve facing upwards. (The position deviation may be within the range of ±10 degrees)
Install water control valve with the up-mark facing up and the frame
center part facing upwards. (The position deviation may be within
the range of ±10 degrees)
Water Outlet Pipe and Heater Pipe
First apply a neutral detergent to O-rings, then quickly insert the insertion parts of the water outlet pipe and
heater pipe into the installation holes.
INSPECTION AFTER INSTALLATION
Check for leaks of engine coolant using radiator cap tester adapter (commercial service tool) and radiator
cap tester (commercial service tool). Refer to CO-37, "
Inspection".
Start and warm up engine. Visually check if there is no leaks of engine coolant.
