ENGINE MAINTENANCE (VQ35DE ENGINE)
Revision: 2004 November 2004 FX35/FX45
4. Remove reservoir tank, drain engine coolant and clean reservoir tank before installing.
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 are removed, close and tighten them. Refer to EM-126, "
ASSEMBLY" .
2. Remove air relief plug on heater hose.
3. Fill radiator and reservoir tank to specified level.

Use Genuine NISSAN Long Life Antifreeze/ Coolant or
equivalent mixed with water (distilled or demineralized).
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS".

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.

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.
Watch engine coolant 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.Radiator drain plug:
: 1.18 N·m (0.12 kg-m, 10 in-lb)

Engine coolant capacity
(with reservoir tank at “MAX” level)

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 engine coolant up to filler neck of thermostat housing.
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 steps 3 through 6 until engine coolant level
no longer drops.

Clean excess engine coolant from engine.
FLUSHING COOLING SYSTEM
1. Install reservoir tank, and radiator drain plug.
If cylinder block water drain plugs are removed, close and tighten them. Refer to EM-244, "
ASSEM-
BLY" .
2. Fill thermostat housing with water until water spills from the air relief hole, then close air relief plug. Fill
thermostat housing and reservoir tank with water and reinstall radiator cap.
3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
6. Drain water from the system. Refer to MA-22, "
DRAINING ENGINE COOLANT" .
7. Repeat steps 1 through 5 until clear water begins to drain from radiator.Reservoir tank engine coolant capacity
(at “MAX” level):
