• When the lock nut is loosened excessively, the idle
r pulley tilts and the correct tension adjust-
ment cannot be performed. Never loo sen it excessively (more than 45 degrees).
• Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt. CAUTION:
• When checking immediately after in stallation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflec-
tion between pulleys.
• When the tension adjustment is performed, the lo ck nut should be in the condition at step“2”. If
the tension adjustment is performed when the lo ck nut is loosened more than the standard, the
idler pulley tilts and the correct tens ion adjustment cannot be performed.
3. Tighten the idler pulley lock nut.
ENGINE COOLANT
ENGINE COOLANT : Inspection INFOID:0000000004806014
LEVEL CHECK • Check if the reservoir tank engine coolant level is within the “MIN” to “MAX” range when engine is cool.
• Adjust the engine coolant level as necessary.
CHECKING COOLING SYSTEM FOR LEAKS To check for leaks, apply pressure to the cooling system using suit-
able tool and Tool.
WARNING:
Never remove the radiator cap wh en the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
ENGINE COOLANT : Chang ing Engine Coolant INFOID:0000000004806015
WARNING:
• To avoid being scalded, do not change engine coolant when engine is hot.
• Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter of a
turn to release built-up pressure. Then turn the cap all the way.
CAUTION:
• Do not spill engine coolant on drive belt.

1. Open radiator drain plug (1) at the bottom of radiator, and then remove radiator cap.
• Front
When draining all of engine coolant in the system, open
water drain plug on cylinder block. Refer to EM-96 .
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
2. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing. Refer to CO-16, " Component " .
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush the engine cooling system.
REFILLING ENGINE COOLANT
1. Install the radiator drain plug. Install the reservoir tank and cylinder block drain plug, if removed for a total
system drain or for engine removal or repair.
• The radiator must be complete ly empty of coolant and water.
• Apply sealant to the threads of the cylinder bl ock drain plugs. Use Genuine High Performance
Thread Sealant or equivalent. Refer to GI-42, " Recommended Chemical Product and Sealant " .
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.
4. Install the Tool by installing the radiator cap adapter onto the radiator neck opening. Then attach the gauge body assembly
with the refill tube and the venturi assembly to the radiator cap
adapter.
5. Insert the refill hose into the coolant mixture container that is placed at floor level. Make sure the ball valve is in the closed
position.
• Use Genuine NISSAN Long Life Anti-freeze coolant or
equivalent, mixed with distil led water or demineralized
water.
Refer to MA-15, " Anti-freeze Coolant Mixture Ratio " .
6. Install an air hose to the venturi assembly, the air pressure must be within specification.
CAUTION:
The compressed air supply must be equipped with an air dryer.
7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open the ball valve on the refill hose slightly. Coolant will be vi sible rising in the refill hose. Once the refill hose is
full of coolant, close the ball valve. This will purge any air trapped in the refill hose. PBIC3799E

8. Continue to draw the vacuum until the gauge reaches 28 inches
of vacuum. The gauge may not reach 28 inches in high altitude
locations, use the vacuum specifications based on the altitude
above sea level.
9. When the vacuum gauge has reached the specified amount, disconnect the air hose and wait 20 seconds
to see if the system loses any vacuum. If the vacuum level drops, perform any necessary repairs to the
system and repeat steps 6 - 8 to br ing the vacuum to the specified amount. Recheck for any leaks.
10. Place the coolant container (with the refill hose inserted) at the same level as the top of the radiator. Then
open the ball valve on the refill hose so the coolant will be drawn up to fill the cooling system. The cooling
system is full when the vacuum gauge reads zero.
CAUTION:
Do not allow the coolant container to get too low when filling, to avoid air from being drawn into
the cooling system.
11. Remove the Tool from the radiator neck opening.
12. Fill the cooling system reservoir tank to the specif ied level and install the radiator cap. Run the engine to
warm up the cooling system and top up the system as necessary.
FLUSHING COOLING SYSTEM 1. Install reservoir tank if removed. Refer to CO-16, " Component " .
2. Install radiator drain plug. •If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-96, " Disassem-
bly and Assembly " .
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-16, " Component " .
3. Fill radiator and reservoir tank with water and reinstall radiator cap.
4. Run engine and warm it up to normal operating temperature.
5. Rev engine two or three times under no-load.
6. Stop engine and wait until it cools down.
7. Drain water from the cooling system.
8. Repeat steps 1 through 7 until clear water begins to drain from radiator.

1. Warm up CVT fluid by driving the vehicle for 10 minutes.
• : Vehicle front
• Radiator (2)
• CVT fluid cooler hose [inlet side (3)]
• Transaxle assembly (4)
2. Drain CVT fluid from CVT fluid cooler hose [outlet side (1)] and refill with new specified NISSAN CVT fluid in the CVT fluid
charging pipe with the engine running at idle speed.
CAUTION:
Only use the specifi ed NISSAN CVT fluid.
3. Refill until new CVT fluid comes out from CVT fluid cooler hose [outlet side (1)]. NOTE:
About 30 to 50% extra fluid will be required for this procedure.
4. Check fluid level and condition. Refer to MA-38, " CVT FLUID : Checking CVT Fluid (RE0F08A) " .
CAUTION:
Delete CVT fluid deterioration date with CONSULT-III after changing CVT fluid. Refer to CVT-51," CONSULT-III Function (TRANSMISSION) " .
CVT FLUID : Checking CVT Fluid (RE0F08B) INFOID:0000000004803428
FLUID LEVEL CHECK Fluid level should be checked with the fluid warmed up to 50 ° to 80 °C (122 ° to 176 °F).
1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle to warm up the CVT fluid. When ambient temperature is 20 °C (68 °F), it takes
about 10 minutes for the CVT fluid to warm up to 50 ° to 80 °C
(122 ° to 176 °F).
3. Park the vehicle on a level surface and set the parking brake.
4. With engine at idle, while depressing brake pedal, move the selector lever throughout the entire shift range and return it to
the “P” position. Fluid status Conceivable cause Required operation
Varnished (viscous
varnish state) Clutch, brake
scorched Replace the CVT fluid and check the
CVT main unit and the vehicle for
malfunctions (wire harness, cooler
pipes, etc.)
Milky white or cloudy Water in the fluid Replace the CVT fluid and check for places where water is getting in.

CAUTION:
Do not spill clutch fluid onto painted surfaces. If it spills, wipe up immediately and wash the affected
area with water.
NOTE:
• Do not use a vacuum assist or any other type of pow er bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all the air from the system.
• Carefully monitor fluid level in reservoir tank during bleeding operation.
1. Fill master cylinder reservoir tank with new clutch fluid.
2. Connect a transparent vinyl tube and container to the bleeding connector (1) on the CSC.
3. Depress and release the clutch pedal slowly and fully 15 times at an interval of two to three seconds and release the clutch
pedal.
4. Push in the lock pin (1) of the bleeding connector (2), and maintain the position. • RS5F91R transaxle models
CAUTION:
Hold the lock pin in to preven t the bleeding connector from
separating when fluid pressure is applied.
