Changing Engine Coolant
Changing Engine CoolantWARNING:
^ To avoid being scalded, do not change engine coolant when engine is hot.
^ Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn cap a quarter of a turn to release built-up pressure. Then turn radiator cap all the way.
^ Be careful not to allow engine coolant to contact drive belts.
DRAINING ENGINE COOLANT
1. Remove undercover with power tool.
2. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
When drain all of engine coolant in the system, open drain plugs on engine cylinder block.
3. Remove reservoir tank, drain engine coolant and clean tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system.
REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION: Be sure to clean drain plug and install with new O-ring.
Radiator drain plug: 1.2 Nm (0.12 kg-m, 11 inch lbs.)
If cylinder block drain plugs are removed, close and tighten them.
2. Remove air relief plug on heater hose.
3. Fill radiator and reservoir tank 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).
Engine coolant capacity (Approximate) (with reservoir tank at MAX level): 8.7 l (9 - 1/4 US qt, 7 - 5/8 Imp qt)
Reservoir tank capacity (at MAX level): 0.8 l (7/8 US qt, 3/4 Imp qt)
^ When engine coolant overflows air relief hole on heater hose, install air relief plug with new O-ring.
Air relief plug: 1.2 Nm (0.12 kg-m, 11 inch lbs.)
4. Warm up engine to normal operating temperature with radiator cap installed.
5. Run engine at 3,000 rpm for 10 seconds and return to idle speed.
^ Repeat two or three times.
CAUTION: Watch water temperature gauge so as not to overheat engine.
6. Stop engine and cool down to less than approximately 50°C (122°F).
^ Cool down using a 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 engine coolant level no longer drops.
9. Check cooling system for leaks with engine running.
10. 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.
11. Repeat step 10 three times.
12. If sound is heard, bleed air from cooling system by repeating step 3 through 6 until engine coolant level no longer drops.
^ Clean excess engine coolant from engine.
