Refilling Engine Coolant

ENGINE COOLANT

Refilling


CAUTION:
- Do not reuse O-rings.
- Do not 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 the following table:
1.Install reservoir tank if removed, and radiator drain plug.

CAUTION:
Be sure to clean drain plug and install with new O-ring. Refer to "Exploded View" Exploded View.





If water drain plug on cylinder block is removed, close and tighten it. Refer to "Disassembly and Assembly" Disassembly and Assembly.
2.Check that each hose clamp is firmly tightened.





3.Remove air relief plug (1) on heater hose.










4.Fill radiator, and reservoir tank, to specified level.
-Pour engine coolant through engine coolant filler neck slowly of less than 3 (2-5/8 imp qt) a minute to allow air in system to escape.

Reservoir tank engine coolant capacity (At "MAX" level)





5.When engine coolant overflows air relief hole on heater hose, install air relief plug with clamp. Then refill radiator with engine coolant.
6.Install radiator cap.
7.Install reservoir tank cap.
8.Warm up engine until opening thermostat less than 3,000 rpm.
- 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.
9.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.
10.Refill reservoir tank to "MAX" level line with engine coolant if necessary.
11.Repeat steps 6 through 10 two or more times with reservoir tank cap installed until engine coolant level no longer drops.
12.Check cooling system for leakage with engine running.
13.Warm up the 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.
14.Repeat step 13 three times.
15.If sound is heard, bleed air from cooling system by repeating step 4, and steps from 6 to 14 until engine coolant level no longer drops.
