7. Remove engine coolant temperature sensor as necessary.
CAUTION:
Be careful not to damage engine coolant temperature sensor.
8. Remove water outlet, heater pipe, water bypass pipe and water connector.
INSTALLATION
Note the following, and install in the reverse order of removal.

Securely insert each hose, and install clamp at a position where it does not interfere with the pipe bulge.

When inserting water bypass pipe and heater pipe into water connector, apply neutral detergent to O-ring.
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.

CVT FLUID

9. Check CVT fluid condition.

If CVT fluid is very dark or smells burned, check operation of
CVT. Flush cooling system after repair of CVT.

If CVT fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of CVT. Refer to CO-37,
"RADIATOR" .
Changing CVT FluidBCS001FY
1. Warm up CVT fluid by driving the vehicle for 10 minutes.

2. Drain CVT fluid from CVT fluid cooler hose [outlet side (1)] and
refill with new CVT fluid at CVT fluid charging pipe with the
engine running at idle speed.
3. Refill until new CVT fluid comes out from CVT fluid cooler hose
[outlet side (1)].
About 30 to 50% extra fluid will be required for this procedure.
CAUTION:

Use only Genuine NISSAN CVT Fluid NS-2. Do not mix with other fluid.

Using CVT fluid other than Genuine NISSAN CVT Fluid NS-2 will deteriorate in driveability and
CVT durability, and may damage the CVT, which is not covered by the warranty.

When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.

Delete CVT fluid deterioration date with CONSULT-II after changing CVT fluid. Refer to CVT-46,
"Check CVT Fluid Deterioration Date" .
4. Check fluid leakage, fluid level and condition.

REMOVAL
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
engine coolant escaping from the radiator.
1. Remove engine undercover.
2. Drain engine coolant. Refer to CO-34, "
Changing Engine Coolant" .
CAUTION:
Perform when the engine is cold.
3. Remove air duct (inlet). Refer to EM-131, "
Removal and Installation" .
4. Remove battery. Refer to SC-13, "
Removal and Installation" .
5. Remove air cleaner case (upper and lower), resonator, mass air flow sensor and air duct assembly. Refer
to EM-131, "
Removal and Installation" .
6. Remove fuse and fusible link block from battery bracket.
7. Remove battery bracket.
8. Remove battery bracket mounting.

DTC P1217 ENGINE OVER TEMPERATURE

CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-10, "
Changing Engine
Coolant" . Also, replace the engine oil. Refer to LU-9, "Changing Engine Oil" .
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-15, "
Anti-Freeze Coolant Mixture Ratio" .
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckBBS005GA
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-224,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-224,
"Diagnostic Procedure" .
3. Turn ignition switch ON.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II.
5. If the results are NG, go to EC-224, "
Diagnostic Procedure" .
