ENGINE COOLANT
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,
flush the engine cooling system. Refer to CO-10, "
FLUSHING COOLING SYSTEM" .
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 plug on cylinder block is removed, close and tighten it. Refer to EM-89, "CYLIN-
DER BLOCK" .
2. Make sure that each hose clamp has been firmly tightened.
3. Fill radiator and reservoir tank to specified level.
Pour engine coolant through engine coolant filler neck
slowly of less than 2 (1-3/4 lmp qt) a minute to allow air
in system to escape.
Use Genuine NISSAN Anti-freeze Coolant or equivalent
mixed with water (distilled or demineralized). Refer to
MA-17, "
RECOMMENDED FLUIDS AND LUBRICANTS".
4. Install radiator cap.
5. Warm up until opening thermostat and water control valve. 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.
6. 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.
7. Refill reservoir tank to “MAX” level line with engine coolant.
8. Repeat steps 3 through 6 two or more times with radiator cap installed until the engine coolant level no
longer drops.
9. Check cooling system for leaks with the engine running.
10. Warm up the engine, and check for sound of engine coolant flow while running the 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 the engine coolant
level no longer drops.
