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" .

5. Remove thermostat housing.
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.
