InspectionABS004T8
LEVEL CHECK

Check if the reservoir tank engine coolant level is within the
“MIN” to “MAX” when engine is cool.

Adjust the engine coolant level as necessary.
CHECKING COOLING SYSTEM FOR LEAKS

To check for leaks, apply pressure to the cooling system with
radiator cap tester (commercial service tool) and radiator cap
tester adapter (SST).
WARNING:
Do not 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
damage.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.

If anything is found, repair or replace damaged parts.
Changing Engine CoolantABS004T9
WARNING:

To avoid being scalded, never change engine coolant when engine is hot.

Wrap a thick cloth around cap and carefully remove cap. First, turn cap a quarter of a turn to
release built-up pressure. Then turn cap all the way.
DRAINING ENGINE COOLANT
1. Remove front engine undercover with power tool.
2. Open radiator drain plug at the bottom of radiator, and remove
radiator cap.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
When drain all of engine coolant in the system, open water drain plugs on cylinder block. Refer to
EM-121, "
DISASSEMBLY" .
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.

If contaminated, flush the engine cooling system. Refer to CO-13, "FLUSHING COOLING SYSTEM" .
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.
CAUTION:
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.Radiator drain plug:

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 step 3 through 6 until engine coolant level no
longer drops.

Clean excess engine coolant from engine.
FLUSHING COOLING SYSTEM
1. Fill radiator with water until water spills from the air relief hole, then close air relief plug. Fill radiator and
reservoir tank with water and reinstall radiator cap.
2. Run engine and warm it up to normal operating temperature.
3. Rev engine two or three times under no-load.
4. Stop engine and wait until it cools down.
5. Drain water from the system. Refer to CO-11, "
DRAINING ENGINE COOLANT" .
6. Repeat steps 1 through 5 until clear water begins to drain from radiator.

WARNING:
Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine
coolant escaping from radiator.
REMOVAL
1. Remove front engine undercover with power tool.
2. Drain engine coolant from radiator. Refer to CO-11, "
Changing Engine Coolant" .
CAUTION:
Perform when engine is cold.
3. Remove air duct and air cleaner case assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
4. Remove reservoir tank and reservoir tank bracket.
5. Disconnect A/T fluid cooler hoses from radiator.
