Removal and InstallationECS00FT2
COMPONENTS
CAUTION:

If transaxle assembly is removed from the vehicle, always replace CSC (Concentric slave cylin-
der). Return CSC insert to original position to remove transaxle assembly. Dust on clutch disc
sliding parts may damage CSC seal and may cause clutch fluid leakage.

Be careful not to apply any grease to the clutch disc facing, pressure plate surface and flywheel
surface.
REMOVAL
1. Remove transaxle assembly from the vehicle. Refer to MT-15, "Removal and Installation" .
2. Loosen clutch cover bolts evenly. Then remove clutch cover and clutch disc.
INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch Disc

Check clutch disc for backlash of spline and runout of facing.

Check clutch disc for burns, discoloration or oil or grease leak-
age. Replace if necessary.

Measure backlash to clutch disc spline and input shaft spline at
the circumference of clutch disc. If outside the specification,
replace clutch disc.
1. Flywheel 2. Clutch disc *1, *2 3. Clutch cover
Apply lithium-based grease including molybdenum disulphide.
*1. Do not clean in solvent. *2. When installing, be careful that grease applied to input shaft does not adhere to
clutch disc.
WCIA0637E
Maximum backlash of spline
(at outer edge of disc): 1.0 mm (0.039 in)
Distance of runout check point
(from hub center): 215 mm (8.46 in)
Maximum allowable spline backlash : 1.0 mm (0.039 in)

Revision: June 20062007 Versa

Use a suitable tool to measure the depth to clutch disc facing
rivet heads. If it exceeds the allowable wear limit, replace clutch
disc.
Clutch Cover
Check clutch cover installed on vehicle for unevenness of diaphragm
spring toe height.

If out of limit, adjust the height using Tool (A).

Check clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch cover assembly.
NOTE:

Worn thrust ring will generate a beating noise when tapped at
the rivet with a suitable tool.

Broken thrust ring will make a clinking sound when cover is shaken up and down.

If a trace of burn or discoloration is found on the clutch cover pressure plate to clutch disc contact surface,
repair the surface with sandpaper. If surface is damaged or distorted, replace the assembly.
Flywheel Runout

Check contact surface of flywheel for slight burns or discolora-
tion. Repair flywheel with emery paper.

Check the flywheel runout. Refer to EM-103, "FLYWHEEL
DEFLECTION (M/T MODELS)" .
CAUTION:
Measure flywheel outer face (not on knock pin and clutch cover
mounting hole).
INSTALLATION
1. Clean clutch disc and input shaft splines to remove grease and dust caused by abrasion.
2. Apply recommended grease to clutch disc and input shaft splines.
CAUTION:
Be sure to apply grease to the points specified. Otherwise, noise, poor disengagement, or damage
to the clutch may result. Excessive grease may cause slip or shudder. If it adheres to CSC seal, it
will cause clutch fluid leakage. Wipe off excess grease.
3. Install clutch disc using tool.
4. Install clutch cover. Pre-tighten clutch cover bolts.Wear limit of facing
surface to rivet head: 0.3 mm (0.012 in)

If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-77, "CYLIN-
DER BLOCK" .
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-11, "
Components" .
3. Make sure that each hose clamp has been firmly tightened.
4. Remove air duct assembly. Refer to EM-16, "
AIR CLEANER AND AIR DUCT" .
5. Disconnect heater hose (1) at position ( ) as shown.

Front

Reposition heater hose as high as possible.
6. Fill radiator and reservoir tank to specified level.

Pour engine coolant through engine coolant filler neck
slowly of less than 2 (2 1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.

Use NISSAN Genuine Engine Coolant or equivalent
mixed with water (distilled or demineralized). Fill cooling
system to specification. Refer to MA-11, "
RECOM-
MENDED FLUIDS AND LUBRICANTS".

When engine coolant overflows disconnected heater hose,
connect heater hose, and continue filling the engine coolant, if
heater hose is disconnected.
7. Install radiator cap.
8. Install air duct assembly. Refer to EM-16, "
AIR CLEANER AND AIR DUCT" .
9. Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000
rpm.

Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat the engine.
10. Stop engine and cool down to less than approximately 50°C (122°F).

Cool down using fan to reduce the time.

If necessary, refill radiator up to filler neck with engine coolant.
11. Refill reservoir tank to “MAX” level line with engine coolant.
12. Repeat steps 6 through 11 two or more times with radiator cap installed until engine coolant level no
longer drops.
13. Check cooling system for leaks with engine running.
14. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000
rpm with heater temperature controller set at several position between “COOL” and “WARM”.

Sound may be noticeable at heater unit.
15. Repeat step 14 three times.
16. If sound is heard, bleed air from cooling system by repeating steps 6 through 11 until engine coolant level
no longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed. Refer to CO-11, "RADIATOR" .
2. Install radiator drain plug.

Removal and InstallationEBS00T7D
WAR NIN G:
Do not remove radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a
turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.
REMOVAL
1. Drain engine coolant from radiator. Refer to CO-8, "Changing Engine Coolant" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belt.
2. Remove air duct (inlet). Refer to EM-16, "
AIR CLEANER AND AIR DUCT" .
3. Remove reservoir tank as follows:
a. Disconnect reservoir tank hose.
b. Release the tab (A) in the direction shown by the arrow ( ).
c. Lift up while removing the reservoir tank hose, and remove it.
4. Disconnect harness connector from fan motors, and move harness to aside.
5. Disconnect CVT or A/T fluid cooler hoses if equipped.

Install plug to avoid leakage of CVT or A/T fluid if equipped.
6. Remove radiator hoses (upper and lower).
7. Remove radiator core support cover. Refer toBL-20, "
RADIATOR CORE SUPPORT" .
8. Remove radiator core support (upper) bolts, bolts of stationary
part on the radiator core support side and clip. Lift radiator from
radiator (upper) mount part of radiator core support (upper) (2).
9. Move radiator assembly (1) to the rearward direction of vehicle,
and then lift it upward to remove.
CAUTION:
Do not damage or scratch A/C condenser if equipped and
radiator core when removing.
INSTALLATION
Installation is the reverse order of removal.
CAUTION:
Do not damage or scratch A/C condenser if equipped and radiator core when removing.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant. Refer to CO-8, "LEVEL CHECK" .

Start and warm up engine. Visually check if there is no leaks of engine coolant and CVT or A/T fluid if
equipped. Refer to CVT-16, "
CVT FLUID" or AT-16, "A/T FLUID" .
