engine coolant NISSAN PATROL 2006 Repair Manual

Anti-freeze Coolant Mixture Ratio
The engine cooling system is ®lled at the factory with a high-quality,
year-round, anti-freeze coolant solution. The anti-freeze solution
contains rust and corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only an eth-
ylene glycol anti-freeze with the proper mixture ratio. See the
following examples:

The use of other types of coolant solutions may damage your
cooling system.

4. Check oil level.
5. Start engine. Check area around drain plug and oil ®lter for any
sign of oil leakage.
6. Run engine for a few minutes, then turn it off. After several
minutes check oil level.
Changing Engine Oil Filter
1. Remove oil ®lter with Tool.
WARNING:
Be careful not to burn yourself, as the engine and engine oil
are hot.
2. Clean oil ®lter mounting surface on cylinder block. Coat rubber
seal of new oil ®lter with engine oil.
3. Screw in the oil ®lter until a slight resistance is felt, then tighten
an additional 2/3 of a turn.
4. Add engine oil.
Refer to Changing Engine Oil.
+Clean excess oil from engine.
Changing Engine Coolant
WARNING:
To avoid the danger of being scalded, never change the cool-
ant when the engine is hot.
ÐDRAINING ENGINE COOLANTÐ
1. Move heater TEMP control knob all the way to HOT.
2. Open radiator drain plug at the bottom of radiator.
3. Remove radiator ®ller cap.
Remove reservoir tank, drain coolant, then clean reservoir tank.
Install it temporarily.
+Be careful not to allow coolant to contact drive belts.

4. Remove cylinder block drain plug located at left rear of cylin-
der block.
5. Drain coolant and install reservoir tank, cylinder block drain
plug and radiator drain plug.
6. Fill radiator with water and warm up engine.
7. Stop engine and wait until it cools down.
8. Repeat step 2 through step 7 two or three times.
9. Drain water.
ÐREFILLING ENGINE COOLANTÐ
10. Install reservoir tank, radiator drain plug, and cylinder block
drain plugs.
+Apply sealant to the thread of cylinder block drain plug.
Cylinder block drain plug:
:34-44Nzm (3.5 - 4.5 kg-m, 25 - 33 ft-lb)
11. Fill radiator and reservoir tank with coolant up to the MAX level
and install radiator cap.
For coolant mixture ratio, refer to MA-11.

Pour coolant through coolant ®ller neck slowly to allow air in
system to escape.
12. Warm up engine to normal operating temperature.
13. Run engine at 2,000 rpm for 10 seconds and return to idle
speed.
+Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
14. Stop engine and cool it down.
+Cool down using a fan to reduce the time.
15. Remove the radiator ®ller cap and check coolant level.
+If necessary, re®ll radiator up to ®ller neck with coolant.
16. Re®ll reservoir tank to Max line with coolant.
17. Repeat step 12 through step 16 two or more times.
18. Warm up engine, and check for sound of coolant ¯ow while
running engine from idle up to 2,000 rpm with heater tempera-
ture control set at several positions between COOL and HOT.
+Sound may be noticeable at heater water cock.
19. If sound is heard, bleed air from cooling system by repeating
steps 12 through 16 until coolant level no longer drops.
+Clean excess coolant from engine.

6. Install all injection nozzles with Tool and securely connect fuel
spill tube and delivery tubes.
7. Bleed air from fuel system and check for fuel leakage with
engine running.

Injection tube:
:20-25Nzm (2.2 - 2.5 kg-m, 16 - 18 ft-lb)
Checking Idle Speed
Inspection should be carried out with gears in ``Neutral'' and
with air conditioner and other electrical loads off.
1. Warm up engine until engine coolant temperature indicator
points to the middle of gauge.
2. Attach a diesel tachotester's pick-up to No. 1 fuel injection tube.
3. Race engine two or three times and check idle speed.
