RADIATOR
2007 Versa
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" .

3. Remove water pump.
CAUTION:
Handle water pump vane so that it does not contact any other parts.
Water pump cannot be disassembled and should be replaced as a unit.
INSPECTION AFTER REMOVAL
Visually check that there is no significant dirt or rusting on water
pump body and vane (A).
Make sure that there is no looseness in vane shaft, and that it
turns smoothly when rotated by hand.
Replace water pump, if necessary.
INSTALLATION
Installation is in the reverse order of removal.

INSPECTION AFTER REMOVAL
Place a thread (A) so that it is caught in the valves of thermostat
(1). Immerse fully in a container (B) filled with water. Heat while
stirring.
The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
Continue heating. Check the full open valve lift amount.
After checking the maximum valve lift amount, lower the water
temperature and check the valve closing temperature.

Precautions for On Board Diagnostic (OBD) System of CVT and EngineUCS005XG
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative termi-
nal before any repair or inspection work. The open/short circuit of related switches, sensors, sole-
noid valves, etc. will cause the MIL to light up.
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system,
etc.
Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Service After Replacing TCM and Transaxle Assembly UCS006L3
SERVICE AFTER REPLACING TCM AND TRANSAXLE ASSEMBLY
Perform the applicable service in the following sheet when replacing TCM or transaxle assembly
CAUTION:
Do not start the engine until the service is completed.
“A/T C/U POWER SUPPLY [P1701]” may be indicated soon after replacing TCM or transaxle
assembly (after erasing the memory at the pattern B). Restart the self-diagnosis after erasing the
self-diagnosis result. Check that no error is detected.
NOTE:
Old unit means that the unit has been already used for another vehicle.
PATTERN A
1. Shift the selector lever to “P” position after replacing TCM. Turn the ignition switch ON.
2. Check that the shift position indicator in the combination meter turns ON (It indicates approximately 1 or 2
seconds after turning the ignition switch ON.)
Check the following items if the shift position indicator does not turn ON. Repair or replace the shift
position indicator if necessary.
–The harness between TCM and ROM ASSY in the transaxle assembly is open or short.
–Cable disconnected, loosen, or bent from the connector housing.
PATTERN B
1. Turn the ignition switch ON after replacing each part.
2. Connect CONSULT-II connector to data link connector. Refer to GI-38, "
CONSULT-II Start Procedure" .
3. Start engine.
CAUTION:
Do not start the driving.
4. Touch CONSULT-II screen in the order of “START (NISSAN BASED VHCL)”, “TRANSMISSION”, “DATA
MONITOR”, and “MAIN SIGNALS”.
5. Warm up the transaxle assembly until “ATF TEMP” indicates 48 (approximately 20°C) or more. Turn the
ignition switch OFF.

6. Turn the ignition switch ON.
CAUTION:
Do not start engine.
7. Select “SELF-DIAG RESULTS”.
8. Shift the selector lever to “R” position.
9. Depress slightly the accelerator pedal (Pedal angle: 2/8) while depressing the brake pedal.
10. Perform “ERASE”.
11. Shift the selector lever to “R” position after replacing TCM. Turn the ignition switch OFF.
12. Wait approximately 10 minutes after turning the ignition switch OFF.
13. Turn the ignition switch ON while shifting the selector lever to “R” position.
CAUTION:
Do not start engine.
14. Select “CALIBRATION DATA”.
15. Check that the value on “CALIBRATION DATA” is same as the data after erasing CVT-11, "
Calibration
Data" .
Restart the procedure from step 3 if the values are not same.
16. Shift the selector lever to “P” position.
17. Check that the shift position indicator in the combination meter turns ON (It indicates approximately 1 or 2
seconds after shifting the selector lever to “P” position.)
Check the following items if the shift position indicator does not turn ON. Repair or replace the shift
position indicator if necessary.
–The harness between TCM and ROM ASSY in the transaxle assembly is open or short.
–Cable disconnected, loosen, or bent from the connector housing.
–Power supply and ground of TCM. Refer to CVT-145, "DTC P1701 TRANSMISSION CONTROL MOD-
ULE (POWER SUPPLY)" .
