Changing Engine Coolant
WARNING:
To avoid being scalded, never change the coolant when the
engine is hot.
—DRAINING ENGINE COOLANT—
Heater
1. Set heater system as follows to prevent coolant from remain-
ing in the system.

Move temperature control dial all the way to“HOT”.
Semi-automatic air conditioning
1. Set air conditioning system as follows to prevent coolant from
remaining in the system.
a. Turn ignition switch“ON”and enter a temperature of 32°Con
the heater control.
b. Wait 30 seconds before turning ignition switch“OFF”.
2. Disconnect lower radiator hose and remove radiator cap.
3. Remove reservoir tank, drain coolant, then clean reservoir
tank.
Install it temporarily.

Be careful not to allow coolant to contact drive belts.
4. Remove cylinder block drain plug and air relief plug.
5. Check drained coolant for contaminants such as rust, corro-
sion or discoloration.
If contaminated, flush engine cooling system.
Refer to“FLUSHING COOLING SYSTEM”, MA-21.

—REFILLING ENGINE COOLANT—
6. Install lower radiator hose, reservoir tank and tighten cylinder
block drain plug securely.

Apply sealant to the thread of the cylinder block drain
plug.
:34-44N·m (3.5 - 4.5 kg-m, 25 - 33 ft-lb)
7. Fill up radiator with coolant at the speed of less than 3
(2-5/8
Imp qt)/min.

If coolant spills from the air relief hole without bubbles, rein-
stall the plug.
Air relief plug:
:7-8N·m (0,7 - 0,8 kg-m, 5,1 - 5,8 ft-lb)
Then pour coolant in again.

Use genuine NISSAN Anti-Freeze Coolant or equivalent.
Refer to“RECOMMENDED FLUIDS AND LUBRICANTS”,
MA-16.
Coolant capacity (With reservoir tank):
Unit: (Imp qt)
QG16DE/QG18DE6.1 (5-3/8)
8. Fill radiator and reservoir tank to specified level.
9. Start engine without installing radiator cap and warm it up at
2,000 rpm until radiator lower hose becomes hot.

If coolant level becomes low, refill coolant until coolant level
does not change.

If coolant overflows radiator filler hole, install filler cap.
10. Run engine at 2,500 rpm for 10 seconds and return to idle
speed.

Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
11. Stop engine and wait until it cools down.

If necessary, refill radiator up to filler neck.
12. Refill reservoir tank to Max line with coolant.
13. Repeat steps 9 through 12 two or more times with radiator
cap installed until coolant level no longer drops.
14. Check cooling system for leaks with engine running.
15. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 3,000 rpm with heater tem-
perature control set at several positions between COOL and
HOT.

Sound may be noticeable at heater water cock.
16. If the sound is heard, bleed air from cooling system by
repeating steps 9 through 12 until coolant level no longer
drops.

Checking Positive Crankcase Ventilation
(PCV) System
CHECKING PCV VALVE
With engine running at idle, disconnect ventilation hose from
PCV valve. If valve is working correctly, a hissing noise will be
heard as air passes through it, and a strong vacuum should be
felt immediately when a finger is placed over valve inlet.
CHECKING VENTILATION HOSES
1. Check hoses and hose connections for leaks.
2. Disconnect all hoses and clean with compressed air. If any
hose cannot be freed of obstructions, replace.
Checking Vacuum Hoses and Connections
Check vacuum hoses for leaks, cracks, damage, loose
connections, chafing and deterioration.
Refer to Vacuum Hose Drawing in EMISSION CONTROL
OVERALL SYSTEM in EC section.
Checking EVAP Vapour Lines
1. Visually inspect vapor lines for leaks, cracks, damage, loose
connections, chafing and deterioration.
2. Inspect vacuum relief valve of fuel tank filler cap for clogging,
sticking, etc.
Refer to EVAPORATIVE EMISSION CONTROL SYSTEM
INSPECTION in EC section.
