ENGINE COOLANT

Inspection

INFOID:0000000001534600

LEVEL CHECK

• Check if the reservoir tank engine coolant level is within the “MIN”

to “MAX” range 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 using suit-
able tool.

WARNING:

Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.

CAUTION:

Higher pressure than specified may cause radiator damage.

Changing Engine Coolant

INFOID:0000000001534601

WARNING:

• To avoid being scalded, do not change engine coolant when engine is hot.
• Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter of a

turn to release built-up pressure. Then turn the cap all the way.

• Be careful not to allow engine coolant to contact drive belt. 

DRAINING ENGINE COOLANT

1.

Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap. 

 Front

When drain all of engine coolant in the system, open water
drain plug on cylinder block. Refer to 

EM-100, "Exploded

View"

.

CAUTION:

• Perform this step when engine is cold. 
• Do not spill engine coolant on drive belt.

2.

Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.

3.

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

CO-11, "Changing Engine Coolant"

.

REFILLING ENGINE COOLANT 

1.

Install reservoir tank if removed.

ENGINE COOLANT

2.

Install radiator drain plug.
• If water drain plug on cylinder block is removed, close and tighten it. Refer to 

EM-100, "Exploded

View"

.

CAUTION:

Be sure to clean radiator drain plug and install with new O-ring. Refer to 

CO-16, "Component"

.

3.

Make sure that each hose clamp has been firmly tightened.

4.

Remove air duct assembly. Refer to 

EM-27, "Exploded View"

.

5.

Disconnect heater hose (1) at position (

) as shown. 

 Front

• Reposition heater hose as high as possible.

6.

Fill radiator and reservoir tank 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 NISSAN Genuine Engine Coolant or equivalent mixed

with water (distilled or demineralized). Fill cooling system
to specification. Refer to 

MA-19, "Fluids and Lubricants"

.

• When engine coolant overflows disconnected heater hose,

connect heater hose, and continue filling the engine coolant, if
heater hose is disconnected.

7.

Install radiator cap.

8.

Install air duct assembly. Refer to 

EM-27, "Exploded View"

.

9.

Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000
rpm.
• Make sure 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 the engine.

10. Stop 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.

11. Refill reservoir tank to “MAX” level line with engine coolant.
12. Repeat steps 6 through 11 two or more times with radiator cap installed until engine coolant level no

longer drops.

13. Check cooling system for leaks with engine running.
14. 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. 

15. Repeat step 14 three times.

16. If sound is heard, bleed air from cooling system by repeating steps 6 through 11 until engine coolant level

no longer drops.   

FLUSHING COOLING SYSTEM

1.

Install reservoir tank if removed.

2.

Install radiator drain plug.
• If water drain plug on cylinder block is removed, close and tighten it. Refer to 

EM-100, "Exploded

View"

.

CAUTION:

Be sure to clean radiator drain plug and install with new O-ring. Refer to 

CO-16, "Component"
