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.

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-61, ªFLUSHING COOLING SYSTEMº.
7. Blow the coolant around the exhaust tube heat shield.

Ð REFILLING ENGINE COOLANT ÐNLLC0079S021. Install reservoir tank, 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 (where fitted) and rear side intake manifold water
tubes
+Fill coolant to the level of the radiator cap at a rate of 2!(1-3/4
Imp qt)/min or lower.
(Close the 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.

Bleeding Hydraulic SystemNLST00141. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Then quickly turn steer-
ing wheel fully to right and left and lightly touch steering stop-
pers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine.
Repeat step 2. above.
+Incomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a) Air bubbles in reservoir tank
b) Clicking noise in oil pump
c) Excessive buzzing in oil pump
Fluid noise may occur in the valve or oil pump. This is common
when the vehicle is stationary or while turning the steering wheel
slowly. This does not affect the performance or durability of the
system.

Checking Steering Wheel Turning ForceNLST00151. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-
ture. [Make sure temperature of fluid is approximately 60 to
80°C (140 to 176°F).]
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360°from the neutral position.
Steering wheel turning force:
26 - 32 N (2.7 - 3.3 kg, 5.8 - 7.2 lb)
5. If steering wheel turning force is out of specification, check
rack sliding force.
a. Disconnect steering column lower joint and knuckle arms from
the gear.
b. Start and run engine at idle to make sure steering fluid has
reached normal operating temperature.
c. Pull tie-rod slowly to move it from neutral position to±11.5 mm
(±0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack
sliding force is within specification.
Average rack sliding force:
197 - 255 N (20.1 - 26.0 kg, 44.3 - 57.3 lb)
6. If rack sliding force is not within specification, replace steering
gear assembly.
7. If rack sliding force is OK, inspect steering column. Refer to
ST-13.
