When drain all of engine coolant in the system, open water drain plug on cylinder block. Refer to
EM-82, "
CYLINDER BLOCK" .
3. Remove reservoir tank and drain 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, and radiator drain plug.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring.

If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-82, "CYLIN-
DER BLOCK" .
2. 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".
3. Warm up engine to normal operating temperature with radiator cap installed.
4. 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 the engine.
5. 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.
6. Refill reservoir tank to “MAX” level line with engine coolant.
7. Repeat steps 2 through 5 two or more times with radiator cap installed until engine coolant level no longer
drops.
8. Check cooling system for leaks with engine running.
9. 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.
10. Repeat step 9 three times.
11. If sound is heard, bleed air from cooling system by repeating steps 2 through 5 until engine coolant level
no longer drops.

Clean excess engine coolant from engine.Engine coolant capacity

3. Remove air relief plug.
4. Open cylinder block drain plug. Refer to EM-212, "
CYLINDER BLOCK" .
5. Remove reservoir tank, drain engine coolant, then clean reservoir tank.
6. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush engine cooling system. Refer to CO-33, "
FLUSHING COOLING SYSTEM" .
REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring.

If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-82, "CYLIN-
DER BLOCK" .
2. 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".

When engine coolant overflows air relief hole, install air relief
plug with new copper washer.
3. Warm up engine to normal operating temperature without radiator cap installed.

If engine coolant overflows radiator filler hole, install radiator cap.
4. Run engine at 3,000 rpm for 10 seconds and return to idle speed with radiator cap installed.

Repeat two or three times.
CAUTION:
Watch engine coolant temperature gauge so as not to overheat the engine.
5. 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.
6. Refill reservoir tank to MAX level line with engine coolant.
