3.
Remove reservoir tank, drain engine coolant and clean tank before installing.
4.
Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to
CO-12, "FLUSHING COOLING SYSTEM"
.
REFILLING ENGINE COOLANT
1.
Install reservoir tank if remove, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If cylinder block drain plugs are removed, close and tighten them. Refer to
2.
Remove air relief plug on heater hose.
3.
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 Genuine NISSAN Long Life Antifreeze/Coolant or
equivalent mixed with water (distilled or demineralized).
Refer to
GI-46, "RECOMMENDED CHEMICAL PRODUCTS
●
When engine coolant overflows air relief hole on heater hose,
install air relief plug with new O-ring.
4.
Warm up engine to normal operating temperature with radiator cap installed.
5.
Run engine at 3,000 rpm for 10 seconds and return to idle speed.
●
Repeat two or three times.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
6.
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.

7.
Refill reservoir tank to “MAX” level line with engine coolant.
8.
Repeat steps 3 through 6 two or more times with radiator cap installed until engine coolant level no longer
drops.
9.
Check cooling system for leaks with engine running.
10. 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.
11. Repeat step 10 three times.
12. If sound is heard, bleed air from cooling system by repeating step 3 through 6 until engine coolant level no
longer drops.
●
Clean excess engine coolant from engine.
FLUSHING COOLING SYSTEM
1.
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.
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 from the system. Refer to
CO-10, "DRAINING ENGINE COOLANT"
.
6.
Repeat steps 1 through 5 until clear water begins to drain from radiator.

WARNING:
Do not remove radiator cap when 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.
Remove engine cover with power tool. Refer to
EM-18, "INTAKE MANIFOLD COLLECTOR"
.
2.
Remove undercover with power tool.
3.
Drain engine coolant from radiator. Refer to
CO-10, "Changing Engine Coolant"
CAUTION:
Perform when the engine is cold.

●
Install blind plug to avoid leakage of A/T fluid.
5.
Remove air duct (inlet) and air cleaner case. Refer to
EM-16, "AIR CLEANER AND AIR DUCT"
6.
Remove bracket mounting bolt for anchoring A/C piping from vehicle left side, so that A/C piping can be
moved.
7.
Remove reservoir tank and bracket.
8.
Remove radiator hoses (upper and lower) and reservoir tank hose.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
9.
Remove radiator cooling fan assembly. Refer to
.
10. Rotate two radiator upper mount brackets 90 degrees in the
direction as shown in the figure, and remove them.
11. Remove two A/C condenser mounting bolts located in upper
part of radiator.
12. Remove radiator as follows:
CAUTION:
Do not damage or scratch A/C condenser and radiator core when removing.
a.
With lifting and pulling radiator in a rear direction, disassemble
lower mount from radiator core support center.
CAUTION:
Because A/C condenser is onto the front-lower portion of
radiator, moving to rear direction should be at minimum.
