< PRECAUTION >
PRECAUTIONS
• After removing mounting nuts and bolts, separate the mating sur-
face using the seal cutter [SST: KV10111100 (J-37228)] (A) and
remove old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
• Tap (B) the seal cutter [SST: KV10111100 (J-37228)] to insert it,
and then slide (C) it by tapping on the side as shown in the figure.
• In areas where seal cutter [SST: KV10111100 (J-37228)] is difficult
to use, use a plastic hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as a screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1.
Using a scraper (A), remove old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
• Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2.
Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3.
Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-22, "Recommended Chemical Products and Sealants"
.
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 (B), normally apply liquid gasket inside
the holes. Occasionally, it should be applied outside the holes.
Check to read the text of service instruction.
• Within five minutes of liquid gasket application, install the mat-
ing component.
• If liquid gasket protrudes, wipe it off immediately.
• Never 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 instruction, observe them.

Inspection
INFOID:0000000009650538
LEVEL
• Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” when the engine is cool.
• Adjust the engine coolant level if necessary.
CAUTION:
Refill Genuine NISSAN Long Life Antifreeze/Coolant (blue) or
equivalent in its quality mixed with water (distilled or deminer-
alized). Refer to
MA-10, "Fluids and Lubricants"
LEAKAGE
• To check for leakage, apply pressure to the cooling system with the
radiator cap tester (commercial service tool) (A) and radiator cap
tester adapter (commercial service tool) (B).
WARNING:
Never remove radiator cap when engine is hot. Serious burns
could occur from high-pressure engine coolant escaping from
engine cooling system.
CAUTION:
Higher test pressure than specified may cause radiator dam-
age.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.
• If anything is found, repair or replace damaged parts.
Draining
INFOID:0000000009650539
WARNING:
• To avoid being scalded, never 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.
1.
Remove engine under cover.
2.
Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to
.
3.
Remove reservoir tank if 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 system. Refer to
.
Refilling
INFOID:0000000009650540
CAUTION:
• Do not reuse O-rings.
• Do not put additive such as water leak preventive, since it may cause cooling waterway clogging.
• When refilling use Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent in its quality
mixed with water (distilled or demineralized). Refer to
MA-10, "Fluids and Lubricants"
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
2.
Check that each hose clamp has been firmly tightened.
3.
Remove air duct assembly and air cleaner cases (upper and lower) assembly. Refer to
.
4.
Remove air bleeder plug (1) of heater pipe.
5.
Fill radiator, and reservoir tank if removed, 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 (2-1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.
• When coolant comes out from the air bleeder plug of
heater pipe, tighten the bleeder plug.
