• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range 

 in the fig-

ure.

• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.

CAUTION:

Drive belt auto-tensioner and idler pulley must be replaced with new ones when the drive belt is
replaced.

ENGINE COOLANT

ENGINE COOLANT : Inspection

INFOID:0000000011008872

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 as 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-23, "Fluids and Lubricants"

.

• Check that the reservoir tank cap is tightened.

WARNING:

Never remove reservoir tank cap when engine is hot. Serious
burns could occur from high-pressure engine coolant escaping
from reservoir tank.

LEAKAGE

• To check for leakage, fit the adapter 

 to the reservoir tank, and

then connect it to the reservoir tank cap tester [SST: — (M.S.554-
07)] 

 as shown.

WARNING:

Never remove reservoir tank cap when engine is hot. Serious
burns could occur from high-pressure engine coolant escap-
ing from reservoir tank.

CAUTION:

Higher test pressure than specified may cause radiator dam-
age.

• If anything is found, repair or replace damaged parts.

ENGINE COOLANT : Draining

INFOID:0000000011008873

WARNING:

• Never remove radiator cap when engine is hot. Serious burns may occur from high-pressure engine

coolant escaping from radiator. 

• Wrap a thick cloth around the radiator cap. Slowly turn it a quarter of a turn to release built-up pres-

sure. Then turn it all the way.

1.

Remove engine under cover.

2.

Remove reservoir tank cap.

3.

Open radiator drain plug 

 of radiator. 

CAUTION:

Perform this step when engine is cold.

4.

Remove reservoir tank if necessary, and drain engine coolant
and clean reservoir tank before installing. Refer to 

CO-70,

"Exploded View"

.

5.

Check drained engine coolant for contaminants such as rust,
corrosion or discoloration. If contaminated, flush the engine
cooling system. Refer to 

CO-66, "Flushing"

.

ENGINE COOLANT : Refilling

INFOID:0000000011008874

CAUTION:

• Never put additive such as waterleak 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-23, "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.

2.

Check that each hose clamp has been firmly tightened.

3.

Open radiator air relief plug 

. 

4.

Disconnect heater hose 

 at position (

) in the figure.

• Enhance heater hose as high as possible.

5.

Open air relief plug

6.

Fill reservoir tank with engine coolant.

CAUTION:

Never adhere the engine coolant to electronic equipments (alternator etc.).
• Pour coolant slowly of less than 3   (2-5/8 Imp qt) per minute to allow air in system to escape.

•

7.

When engine coolant spill from radiator air relief plug with continuous flow, close air relief plug and con-
tinue filling reservoir tank. 

8.

When engine coolant spill from air relief plug with continuous flow, close air relief plug and continue filling
reservoir tank. 

9.

When engine coolant spill from heater hose with continuous
flow, connect heater hose and continue filling reservoir tank until
reach “MAX” level 

10.

11. Install radiator cap.
12. Warm up engine at 3000 rpm until thermostat is opened.

• Check thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.

CAUTION:

Watch water temperature gauge so as not to overheat engine.

13. Stop the engine and cool down to less than approximately 50

°

C (122

°

F).

• Cool down using fan to reduce the time.
• If necessary, refill radiator up to filler neck with engine coolant.

CAUTION:

Never adhere the engine coolant to electronic equipments (alternator etc.).

14. Refill reservoir tank to “MAX” level line with engine coolant.
15. Repeat steps 11 through 14 two or more times with radiator cap installed until engine coolant level no

longer drops. 

16. Check cooling system for leakage with engine running.
17. Warm up the engine, and check for flowing noise while repeat at least three time slow acceleration from

idle up to 3,000 rpm.

18. If flowing noise is heard, bleed air from cooling system by repeating step 11 through 17 until flowing noise

is no longer heard.
