PRECAUTIONS
3. Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
4. Apply liquid gasket without breaks to the specified location with the specified dimensions.
 If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.
 As for the bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.
 Within five minutes of liquid gasket application, install the mat-
ing component.
 If liquid gasket protrudes, wipe it off immediately.
 Do not retighten after mounting bolts and nuts the installation.
 After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling sys tem. Refer to "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 plugs on cylinder block are removed, close and tighten them. Refer to EM-123, "
Dis-
assembly and Assembly".
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air relief plug on heater hose.
4. Fill radiator, and reservoir tank if removed, to specified level. 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.
 Use Genuine NISSAN Long Li fe Antifreeze/Coolant or
equivalent mixed with water (dis tilled or demineralized).
Refer to MA-9, "
Fluids and Lubricants".
 When engine coolant overflows air relief hole on heater hose, install air relief plug with new O-ring.
5. Install radiator cap.
6. Warm up until opening thermostat. Standard for warm ing-up time is approximately 10 minutes at 3,000
rpm.
 Make sure thermostat opening condition by touching r adiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
7. Stop the engine and cool down to less than approximately 50 °C (122 °F).

ENGINE COOLANT
 Cool down using fan to reduce the time.
 If necessary, refill radiator up to filler neck with engine coolant.
8. Refill reservoir tank to “MAX” level line with engine coolant.
9. Repeat steps 4 through 7 two or more times with radiator cap installed until engine coolant level no longer drops.
10. Check cooling system for leaks with engine running.
11. Warm up the 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.
12. Repeat step 11 three times.
13. If sound is heard, bleed air from cooling system by repeating step 4 through 7 until engine coolant level no
longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed, and radiator drain plug.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-123, "
Dis-
assembly and Assembly".
2. Remove air relief plug on heater hose.
3. Fill radiator with water until water spills from the ai r relief hole, then close air relief plug. Fill radiator and
reservoir tank with water and reinstall radiator cap.
4. Run the engine and warm it up to normal operating temperature.
5. Rev the engine two or three times under no-load.
6. Stop the engine and wait until it cools down.
7. Drain water from the system. Refer to "DRAINING ENGINE COOLANT".
8. Repeat steps 1 through 7 until clear water begins to drain from radiator. Radiator drain plug:

REMOVAL
WARNING:
Do not remove radiator cap when en gine is hot. Serious burns could occur from high-pressure engine
coolant escaping from radiator. Wrap a thick cloth aroun d the cap. Slowly turn it a quarter of a turn to
release built-up pressure. Carefully remove ra diator cap by turning it all the way.
1. Remove front engine undercover with power tool.
2. Drain engine coolant from radiator. Refer to CO-10, "
Changing Engine Coolant".
CAUTION:
 Perform this step when the engine is cold.
 Do not spill engine coolant on drive belts.
3. Remove air duct (inlet) and air cleaner case assembly. Refer to EM-17, "
Component".

when removing.
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION
 Check for leaks of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-10, "
Inspection".
 Start and warm up the engine. Visually make sure t hat there is no leaks of engine coolant and A/T fluid.
Checking Radiator CapINFOID:0000000001325849
 Check valve seat of radiator cap.
- Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
- Check if valve seat has no soil and damage.

 Pull negative-pressure valve to open it, and make sure that it close
completely when released.
- Make sure that there is no dirt or damage on the valve seat of radi-
ator cap negative-pressure valve.
- Make sure that there are no unusualness in the opening and clos- ing conditions of negative-pressure valve.
 Check radiator cap relief pressure.
- When connecting radiator cap to the radiator cap tester (commer- cial service tool) (A) and the radi ator cap tester adapter (commer-
cial service tool) (B), apply engine coolant to the cap seal surface.
 Replace radiator cap if there is an unusualness related to the above three.
CAUTION:
When installing radiator cap, thor oughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking RadiatorINFOID:0000000001325850
Check radiator for mud or clogging. If necessary, clean radiator as follows.
 Be careful not to bend or damage radiator fins.
 When radiator is cleaned without removal, remove all surrounding parts such as radiator cooling fan assem-
bly and horns. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surfaces once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward.  Use compressed air lower than 490 kPa (5 kg/cm
2, 71 psi) and keep distance more than 30 cm (11.81
in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
