4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to CO-36, "
FLUSHING COOLING SYSTEM" .
REFILLING ENGINE COOLANT
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-233,
"ASSEMBLY" .
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air duct assembly. Refer to EM-131, "
AIR CLEANER AND AIR DUCT" .
4. Disconnect heater hose (left side of vehicle) at the position in
the figure.

Enhance heater hose as high as possible.
5. Fill radiator and reservoir tank to specified level.
CAUTION:
Never adhere the engine coolant to electronic equipments
(alternator etc.).

Pour engine coolant through engine coolant filler neck
slowly of less than 2 (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). Refer to
MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".

When engine coolant overflows disconnected heater hose, connect heater hose, and continue filling the
engine coolant.
6. Install air duct assembly. Refer to EM-131, "
AIR CLEANER AND AIR DUCT" .
7. Install radiator cap.Radiator drain plug:

Refer to GI-10, "Components" for symbol marks in the figure.
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 undercover.
2. Drain engine coolant from radiator. Refer to CO-34, "
Changing Engine Coolant" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
3. Remove air duct (inlet). Refer to EM-131, "
AIR CLEANER AND AIR DUCT" .

5. Disconnect A/T fluid cooler hoses (VQ23DE), or CVT fluid cooler hoses (VQ35DE).

Install plug to avoid leakage of A/T fluid or CVT fluid.
6. Remove radiator hoses (upper and lower) and reservoir tank hose.
7. Remove reservoir tank.
8. Remove battery and battery tray, and move fuse and fusible link block to aside. Refer to SC-4, "
BAT-
TERY" .
9. Remove mounting brackets to lift up and remove radiator and radiator cooling fan assembly.
CAUTION:
Do not damage or scratch A/C condenser and radiator core when removing.
10. Remove radiator cooling fan assembly from radiator.
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using radiator cap tester adapter [SST: EG17650301] and radiator cap
tester (commercial service tool). Refer to CO-34, "
LEAK CHECK" .

Start and warm up engine. Visually check if there is no leaks of engine coolant and A/T fluid.
Checking Radiator CapBBS005AW

Check valve seat of radiator cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.

Pull negative-pressure valve to open it, and make sure that it is
completely closed when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.

Check radiator cap relief pressure.
–When connecting radiator cap to the radiator cap tester (com-
mercial service tool) and the radiator cap tester adapter (SST),
apply engine coolant to the cap seal surface.

Replace radiator cap if there is an unusualness related to the above three.
