Refer to GI-11, "Components" for symbols in the figure.
Removal and InstallationNBS004RQ
CAUTION:

When removing water pump, be careful not to get engine coolant on drive belts.

Water pump can not be disassembled and should be replaced as a unit.

After installing water pump, connect hose and clamp securely, then check for leaks using radiator
cap tester (commercial service tool) and radiator cap tester adapter (commercial service tool).
REMOVAL
1. Remove following parts:

Front engine undercover (power tool)

Engine cover: Refer to EM-179, "INTAKE MANIFOLD" .

Engine room cover (RH and LH): Refer to EM-173, "ENGINE ROOM COVER" .

Air duct (inlet): Refer to EM-177, "AIR CLEANER AND AIR DUCT" .

Alternator, water pump and A/C compressor belt: Refer to EM-174, "DRIVE BELTS" .
2. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-40, "
Chang-
ing Engine Coolant" and EM-253, "DISASSEMBLY" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
3. Remove water pump pulley.
4. Remove water pump.

Engine coolant will leak from cylinder block, so have a receptacle ready under vehicle.
CAUTION:

Handle the water pump vane so that it does not contact any other parts.

Do not disassemble water pump.

ENGINE MAINTENANCE (VQ35DE ENGINE)PFP:10001
Checking Drive BeltsNLS0009Y
WARNING:
Be sure to perform when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on belt midway
between pulleys.

Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.

Measure the belt tension with belt tension gauge (Commercial
service tool: BT3373-F or equivalent) at points marked
shown in the figure.

When measuring the deflection, apply 98 N (10 kg, 22 lb) at
the marked point.

Adjust if the belt deflection exceeds the limit or if the belt ten-
sion is not within specifications.
CAUTION:

When checking the belt deflection or the tension immediately after installation, first adjust it to
the specified value. Then, after turning crankshaft two turns or more, re-adjust to the specified
value to avoid variation in deflection between pulleys.

Tighten idler pulley lock nut by hand and measure the deflection or the tension without loose-
ness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.

CAUTION:

When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.

When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.

When checking belt deflection or tension immediately after installation, first adjust it to the speci-
fied value. Then, after turning crankshaft two turns or more, re-adjust to the specified value to
avoid variation in deflection between pulleys.

When installing belt, make sure that it is correctly engaged with pulley grooves.

Keep engine oil, working fluid and engine coolant away from belt and pulley grooves.

Do not twist or bend belt excessively.
ALTERNATOR AND POWER STEERING OIL PUMP BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (A) and adjust tension by turning
adjusting bolt (B).

For the specified belt tension, refer to MA-14, "Checking Drive
Belts" .
3. Tighten nut (A).
A/C COMPRESSOR BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (C) and adjust tension by turning adjusting bolt (D).

For the specified belt tension, refer to MA-14, "Checking Drive Belts" .
3. Tighten nut (C).
Changing Engine CoolantNLS0007J
WARNING:

To avoid being scalded, do not change engine coolant when the engine is hot.

Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.

Be careful not to allow engine coolant to contact drive belts.
DRAINING ENGINE COOLANT
1. Remove engine room cover (RH and LH). Refer to EM-15, "ENGINE ROOM COVER" .
2. Remove air duct (inlet). Refer to EM-19, "
AIR CLEANER AND AIR DUCT" .
3. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
