Changing Engine CoolantNJLC0079WARNING:
To avoid the danger of being scalded, never change the cool-
ant when the engine is hot.
Ð DRAINING ENGINE COOLANT ÐNJLC0079S011. Set air conditioning system as follows to prevent coolant from
remaining in the system.
a. Turn ignition switch ON and set temperature controller to maxi-
mum hot position.
b. Wait 10 seconds before turning ignition switch OFF.

2. Remove lower radiator hose, and remove radiator filler cap to
drain coolant.
3. Remove reservoir tank, drain coolant, then clean reservoir
tank.
+Be careful not to allow coolant to contact drive belts.
4. Cover the exhaust tube heat shield to prevent from splashing
coolant.
JLC429B
YLC026
5. Remove drain plug of cylinder block and air relief plug.
6. Check drained coolant for contaminants such as rust, corro-
sion or discoloration. If contaminated flush engine cooling
system, refer to LC-45, ªFLUSHING COOLING SYSTEMº.
7. Blow the coolant around the exhaust tube heat shield.
NOTE:
An asterisk (*1) in the figure means ªNot installed on some
modelsº.

Ð REFILLING ENGINE COOLANT ÐNJLC0079S021. Install reservoir tank, radiator drain cock or lower radiator hose
and cylinder block drain plug.
+Apply sealant to the thread of cylinder block drain plugs.
:8-11N´m(0.8 - 1.2 kg-m, 70 - 104 in-lb)
2. Fill radiator slowly with coolant until coolant spills from the air
relief plugs, then install air relief plugs.
+Location of air relief plugs
Water inlet and rear side intake manifold water tubes
3. Disconnect heater hose at engine, pour coolant into the hose
so that it flows toward the heater core.

+While filling, if coolant from engine side spills out, be sure to
reconnect the heater hose.
+Fill coolant to the level of the radiator cap at a rate of 2!(1-3/4
Imp qt)/min or lower.
(Close the air relief plugs in order starting with the location from
where the coolant began spilling out.)
CAUTION:
If the filling rate is too fast, this could lead to air being mixed
in the coolant. Be sure to fill the coolant slowly according to
the rate indicated above.
+Replace the copper washer of the air bleeding plug.
Air relief plug:
: 6.7 - 7.9 N´m (0.68 - 0.81 kg-m, 59 - 70 in-lb)
+Use genuine Nissan anti-freeze coolant or equivalent
mixed with water (distilled or demineralized).

Refer to MA-20, ªRECOMMENDED FLUIDS AND LUBRI-
CANTSº.
Engine coolant capacity (With reservoir tank):
8.7!(7-5/8 Imp qt)
Reservoir tank capacity:
0.7!(5/8 Imp qt)
+Pour coolant through coolant filler neck slowly to allow air
in system to escape.
4. Fill radiator and reservoir tank to specified level.
5. Warm up engine to normal operating temperature without
radiator cap installed.
+If coolant overflows radiator filler hole, install radiator cap.
6. Run engine at 3,000 rpm for 10 seconds and return to idle
speed with radiator cap installed.
+Repeat two or three times.
Watch coolant temperature gauge so as not to overheat the
engine.
7. Stop engine and cool it down.
+Cool down using a fan to reduce the time.
+If necessary, refill radiator up to filler neck with coolant.
8. Refill reservoir tank to MAX level line with coolant.
9. Repeat steps 4 through 7 two or more times with radiator cap
installed until coolant level no longer drops.
10. Check cooling system for leaks with engine running.
11. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 3,000 rpm with heater tempera-
ture controller set at several positions between COOL and
HOT.
+Sound may be noticeable at heater water cock.
12. If sound is heard, bleed air from cooling system by repeating
steps 4 through 7 until coolant level no longer drops
+Clean excess coolant from engine.

Ð FLUSHING COOLING SYSTEM ÐNJLC0079S031. Open air relief plug.
2. Fill radiator with water until water spills from the air relief hole,
then close air relief plug. Fill radiator and reservoir tank with
water and reinstall radiator cap.
3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
6. Drain water.
7. Repeat steps 1 through 6 until clear water begins to drain from
radiator.
