WARNING:
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 cl oth 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. Remove engine under cover. Refer to EI-15, "Removal and Installation".
2. Drain engine coolant from radiator. Refer to CO-36, "
Changing Engine Coolant".
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
3. Remove air duct (inlet). Refer to EM-135
.
4. 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.
5. Disconnect harness connector from fan motor, and move harness aside.
6. Disconnect CVT or A/T fluid cooler hoses if equipped. • Install plug to avoid leakage of CVT or A/T fluid if equipped.
7. Remove radiator hoses (upper and lower).
8. Remove radiator core support cover. Refer to BL-19
.
9. Remove cooling fan assembly.
10. 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).
11. 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 in the reverse order of removal.
CAUTION:
Do not damage or scratch A/C condenser if eq uipped and radiator core when installing.
INSPECTION AFTER INSTALLATION
• Check for leaks of engine coolant. Refer to CO-36, "Inspection".
• Start and warm up engine. Visually check for leaks of engine coolant and CVT or A/T fluid if equipped. Refer
to CVT-14
or AT- 1 7.

Hydraulic Control SystemINFOID:0000000005397772
TCM FunctionINFOID:0000000005397773
The function of the TCM is to:
• Receive input signals sent from various switches and sensors.
• Determine required line pressure, shifting point, and lock-up operation.
• Send required output signals to the step motor and the respective solenoids.
CONTROL SYSTEM OUTLINE
The CVT senses vehicle operating conditions through various sensors. It always controls the optimum shift
position and reduces shifting and lock-up shocks.

CVT SYSTEM
mand to the step motor, and control the flow-in/flow-out of line pressure from the primary pulley to determine
the position of the moving-pulley and control the gear ratio.
NOTE:
The gear ratio is set for every position separately.
“D” POSITION
Shifting over all the ranges of gear ratios from the lowest to the high-
est.
OVERDRIVE-OFF MODE
Use this position for the improved engine braking.
“L” POSITION
By limiting the gear range to the lowest position, the strong driving
force and the engine brake can be secured.
DOWNHILL ENGINE BRAKE CONTROL
(AUTO ENGINE BRAKE CONTROL)
When downhill is detected with the accelerator pedal released, the engine brake will be strengthened up by
downshifting so as not to accelerate the vehicle more than necessary.
ACCELERATION CONTROL
According to vehicle speed and a change of accelerator pedal angle, driver's request for acceleration and driv-
ing scene are judged. This function assists improvem ent in acceleration feeling by making the engine speed
proportionate to the vehicle speed. And a shift map which can gain a larger driving force is available for com-
patibility of mileage with driveability.
