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 removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-81, "
CYLINDER
BLOCK" .
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air duct assembly. Refer to EM-17, "
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-17, "
AIR CLEANER AND AIR DUCT" .
7. Install radiator cap.Radiator drain plug:

A widely use engine stand can be used.
CAUTION:
Use engine stand that has a load capacity [approximately
150 kg (331 lb) or more] large enough for supporting the
engine weight.
NOTE:
This example is an engine stand for holding at transaxle
mounting side with drive plate removed.
3. Drain engine oil. Refer to LU-9, "
Changing Engine Oil" .
4. Drain engine coolant by removing water drain plug from inside of
engine.
5. Remove cylinder head. Refer to EM-65, "
CYLINDER HEAD" .
6. Remove knock sensor.
CAUTION:
Carefully handle knock sensor avoiding shocks.
7. Remove crankshaft position sensor (POS).
CAUTION:

Avoid impacts such as a dropping.

Do not disassemble.

Keep it away from metal particles.

Do not place sensor in a location where it is exposed to
magnetism.

A widely use engine stand can be used.
CAUTION:
Use engine stand that has a load capacity [approximately
220 kg (441 lb) or more] large enough for supporting the
engine weight.
NOTE:
This example is engine stand for holding at transaxle mount-
ing side with drive plate removed.
5. Drain engine oil. Refer to LU-21, "
Changing Engine Oil" .
6. Drain engine coolant by removing water drain plugs from cylin-
der block both sides at “A” and “D” and cylinder block front side
at “B” as shown in the figure.
NOTE:
Water drain plug at the right bank side for VQ35DE is also used
as a connector of water pipe for oil cooler. Refer to LU-23, "
OIL
COOLER (VQ35DE)" .
7. Remove drive plate. Fix crankshaft pulley with pulley holder [SST: KV10109300], and remove mounting
bolts.

Loosen mounting bolts in diagonal order.
CAUTION:

Do not disassemble drive plate.

Do not place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
8. Remove cylinder head. Refer to EM-210, "
CYLINDER HEAD" .
9. Remove knock sensor.
CAUTION:
Carefully handle sensor avoiding shocks.

RECOMMENDED FLUIDS AND LUBRICANTS

RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and LubricantsBLS0009C
*1: For further details, see “SAE Viscosity Number”.
*2: Use Genuine NISSAN Anti-freeze Coolant or equivalent in its quality, in order to avoid possible aluminum corrosion within the engine
cooling system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may not be
covered by the warranty even if such incidents occurred during the warranty period.
*3: Contact a Nissan dealership for more information regarding suitable fluids, including recommended brand(s) of DEXRON
TM III/MER-
CONTM Automatic Transmission Fluid.
*4: Using transmission fluid other than Genuine NISSAN CVT Fluid NS-2 will damage the CVT, which is not covered by the war-
ranty.
*5: DEXRON
TM III type ATF can be used.
*6: Never mix different type of fluids (DOT 3 and DOT 4).Capacity (Approximate)
