Removal and Replacement

ENGINE COOLANT: Draining

WARNING:
^ To avoid being scalded, do not change engine coolant when the engine is hot.
^ Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a quarter of a turn to release built-up pressure. Then turn radiator cap all the way.

1. Open radiator drain plug (2) at the bottom of radiator, and then remove radiator cap.





1: Engine under cover
A: Radiator drain plug hole
When draining all of engine coolant in the system, open water drain plugs on cylinder block.
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.

ENGINE COOLANT: Refilling
1. Remove air cleaner case (LH).
2. 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 on cylinder block are removed, close and tighten them.
3. Make sure that each hose clamp has been firmly tightened.





4. Remove air relief plug (2) on radiator left side.
1: Reservoir tank
3: Engine cover
5. Remove air relief plug (1) on heater hose.





2: Heater hose





6. Fill radiator, and reservoir tank if removed, to specified level.
^ Pour engine coolant through engine coolant filler neck slowly of less than 2 l (2-1/8 US qt, 1-3/4 Imp qt) a minute to allow air in system to escape.
^ Use Genuine NISSAN Long Life Antifreeze/Coolant or equivalent mixed with water (distilled or demineralized).





A: MAX
B: MIN
7. When engine coolant overflows air relief hole on radiator, install air relief plug with new O-ring.
8. Repeat step 6.
9. When engine coolant overflows air relief hole on heater hose, install air relief plug with new O-ring. Then refill radiator with engine coolant.
Torque: 1.2 Nm (0.12 kg-m, 11 in-lb)
10. Install air cleaner case (LH).
11. Install radiator cap.
12. Warm up engine 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 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.
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 leaks with engine running.
17. 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.
18. Repeat step 17 three times.
19. If sound is heard, bleed air from cooling system by repeating step 6, and steps from 11 to 18 until engine coolant level no longer drops.
20. Check that the reservoir tank cap is tightened.
