Inspection
INFOID:0000000005518090
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.
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
radiator.
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:0000000005518091
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:0000000005518092
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.
Disconnect heater hose (1) at the position (
) in the figure.
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 engine coolant overflows disconnected heater
hose, connect heater hose, and continue filling the engine
coolant.
• Use Genuine NISSAN Long Life Antifreeze/Coolant or
equivalent mixed with water (distilled or demineralized).
