1.
Install reservoir tank, lower radiator hose and cylinder block
drain plug.
I
Apply sealant to the thread of cylinder block drain plugs.
: 8 - 11 N·m (0.8 - 1.2 kg-m, 70 - 104 in-lb)
2.
Fill radiator to specified level.
I
Fill coolant to the level of the radiator cap at a rate of 2
(1-3/4
Imp qt)/min or lower.
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.
I
Use genuine Nissan anti-freeze coolant or equivalent.
Refer to MA-20, “RECOMMENDED FLUIDS AND LUBRI-
CANTS”.
Engine coolant capacity (With reservoir tank):
7.05
(6–1/4 Imp qt)
Reservoir tank capacity:
0.7
(5/8 Imp qt)
I
Pour coolant through coolant filler neck slowly to allow air
in system to escape.
SMA412B
3.
Fill reservoir tank to specified level.
4.
Warm up engine to normal operating temperature without
radiator cap installed.
I
If coolant overflows radiator filler hole, install radiator cap.
5.
Run engine at 3,000 rpm for 10 seconds and return to idle
speed with radiator cap installed.
I
Repeat two or three times.
Watch coolant temperature gauge so as not to overheat the
engine.
6.
Stop engine and cool it down.
I
Cool down using a fan to reduce the time.
I
If necessary, refill radiator up to filler neck with coolant.
7.
Refill reservoir tank to MAX level line with coolant.
8.
Repeat steps 4 through 7 two or more times with radiator cap
installed until coolant level no longer drops.
9.
Check cooling system for leaks with engine running.
10. 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.
I
Sound may be noticeable at heater water cock.
11. If sound is heard, bleed air from cooling system by repeating
steps 4 through 7 until coolant level no longer drops
I
Clean excess coolant from engine.
