2. Install radiator drain plug.
If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-100, "
Exploded
View".
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-16, "
Component".
3. Make sure that each hose clamp has been firmly tightened.
4. Remove air duct assembly. Refer to EM-27, "
Exploded View".
5. Disconnect heater hose (1) at position ( ) as shown.
 Front
 Reposition heater hose as high as possible.
6. Fill radiator and reservoir tank to specified level.
Pour engine coolant through engine coolant filler neck
slowly of less than 2 (2 1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.
Use NISSAN Genuine Engine Coolant or equivalent mixed
with water (distilled or demineralized). Fill cooling system
to specification. Refer to MA-19, "
Fluids and Lubricants".
 When engine coolant overflows disconnected heater hose,
connect heater hose, and continue filling the engine coolant, if
heater hose is disconnected.
7. Install radiator cap.
8. Install air duct assembly. Refer to EM-27, "
Exploded View".
9. 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 the engine.
10. Stop engine and cool down to less than approximately 50°C (122°F).
 Cool down using fan to reduce the time.
 If necessary, refill radiator up to filler neck with engine coolant.
11. Refill reservoir tank to “MAX” level line with engine coolant.
12. Repeat steps 6 through 11 two or more times with radiator cap installed until engine coolant level no
longer drops.
13. Check cooling system for leaks with engine running.
14. 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.
15. Repeat step 14 three times.
16. If sound is heard, bleed air from cooling system by repeating steps 6 through 11 until engine coolant level
no longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed.
2. Install radiator drain plug.
If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-100, "
Exploded
View".
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-16, "

Do not remove radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a
turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.
REMOVAL
1. Drain engine coolant from radiator. Refer to CO-11, "Changing Engine Coolant".
CAUTION:
 Perform this step when engine is cold.
 Do not spill engine coolant on drive belt.
2. Remove air duct (inlet). Refer to EM-27, "
Exploded View".
3. Remove reservoir tank as follows:
a. Disconnect reservoir tank hose.
b. Release the tab (A) in the direction shown by the arrow ( ).
c. Lift up while removing the reservoir tank hose, and remove it.
4. Disconnect harness connector from fan motor, and move harness aside.
5. Disconnect A/T fluid cooler hoses if equipped.
 Install plug to avoid leakage of A/T fluid if equipped.
6. Remove radiator hoses (upper and lower).
7. Remove radiator core support cover.
8. Remove radiator core support (upper) bolts, bolts of stationary
part on the radiator core support side and clip. Lift radiator
assembly (1) from radiator (upper) mount part of radiator core
support (upper) (2).
9. Move radiator assembly (1) to the rearward direction of vehicle,
and then lift it upward to remove.
CAUTION:
Do not damage or scratch A/C condenser if equipped and
radiator core when removing.
INSTALLATION
Installation is the reverse order of removal.
CAUTION:
Do not damage or scratch A/C condenser if equipped and radiator core when removing.
INSPECTION AFTER INSTALLATION
 Check for leaks of engine coolant.
 Start and warm up engine. Visually check if there is no leaks of engine coolant and A/T fluid if equipped.

INSPECTION AFTER REMOVAL
WARNING:
Use a protector to prevent a burn during the work.
Thermostat
 Place a thread (A) so that it is caught in the valves of thermostat
(1). Immerse fully in a container (B) filled with water. Heat while
stirring.
 The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
 Continue heating. Check the full open valve lift amount.
 After checking the maximum valve lift amount, lower the water
temperature and check the valve closing temperature.
 If out of the standard, replace thermostat.
INSPECTION AFTER INSTALLATION
 Check that the reservoir tank cap is tightened.
 Check for leaks of engine coolant using suitable tools. Refer to CO-11, "
Inspection".
