System DiagramINFOID:0000000003767312
System DescriptionINFOID:0000000003766890
 Traction Control System is a function that electronically controls engine torque, brake fluid pressure and
CVT shift position to ensure the optimum slippage ratio at drive wheels by computing wheel speed signals
from 4 wheel sensors. When ABS actuator and electric unit (control unit) detects a spin at drive wheels (rear
wheels), it compares wheel speed signals from all 4 wheels. At this time, LH and RH rear brake fluid pres-
sure are controlled, while fuel being cut to engine and throttle valve being closed to reduce engine torque by
the control unit. Further more, throttle position is continuously controlled to ensure the optimum engine
torque at all times.
 During TCS operation, TCS informs driver of system operation by flashing SLIP indicator lamp.
 Electrical system diagnosis by CONSULT-III is available.

RADIATOR
WARNING:
Never remove radiator cap when 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.
1. Remove the following parts:
 Engine under cover.
 Air duct (inlet): Refer to EM-26, "
Exploded View".
 Horn: Refer to HRN-6, "
Exploded View".
 Hood lock: Refer to DLK-220, "
Exploded View".
2. Drain engine coolant from radiator. Refer to CO-8, "
Draining".
CAUTION:
 Perform this step when the engine is cold.
 Never spill engine coolant on drive belt.
3. Disconnect reservoir tank hose from radiator pipe (upper).
4. Disconnect CVT fluid cooler hoses from radiator.
 Install blind plug to avoid leakage of CVT fluid.
5. Disconnect Low-pressure flexible hose from lower pressure pipe, and then move it to aside. Refer to HA-
38, "Exploded View".
6. Remove radiator cap adapter and radiator hoses (upper) and radiator pipe (upper) assembly.
CAUTION:
Be careful not to allow engine coolant to contact drive belt.
7. Disconnect radiator hose (lower) from radiator.
8. Remove condenser. Refer to HA-46, "
Exploded View".
CAUTION:
Be careful not to damage condenser core.
9. Remove radiator upper clip (2) by pulling the tabs (A) outside to
release the lock (B) and then remove mounting rubbers (upper)
(1).
CAUTION:
Never pull the tabs outside excessively to prevent it from
damping.
10. Lift up and remove radiator from front of radiator core support.
CAUTION:
Be careful not to damage or scratch on radiator core.
INSTALLATION
Note the following, and installation is the reverse order of removal.
Radiator Upper Clip
Install radiator upper clip on radiator core connection as follows:
1. Install mounting rubbers (upper) (1) on mounting pins (A) of radi-
ator.
2. Align radiator upper clip (2) with radiator core connection (B),
then insert radiator upper clip straight into radiator core connec-
tions until a click is heard.
3. After connecting radiator upper clip, use the following method to
check it is fully connected.
 Visually confirm that two radiator upper clips are connected to
radiator core connections.
 Move radiator upper clip and the radiator forward and backward to check they are securely connected.

INSPECTION AFTER INSTALLATION
 Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-8, "
Inspection".
 Start and warm up the engine. Visually check that there is no leakage of engine coolant and CVT fluid.

WATER OUTLET AND WATER PIPING
5. Remove CVT fluid charging pipe and CVT fluid level gauge. Refer to TM-332, "Exploded View" (VQ25DE)
or TM-168, "
Exploded View" (VQ35DE).
6. Move CVT control cable aside. Refer to TM-319, "
Exploded View" (VQ25DE) or TM-157, "Exploded View"
(VQ35DE).
7. Remove vacuum pipe (front) mounting bolt from water outlet. Refer to EM-67, "
Exploded View".
8. Remove radiator hose (upper) from water outlet.
9. Remove water hoses and heater hoses.
10. Disconnect harness connectors, and move harness to aside.
11. Remove engine coolant temperature sensor as necessary.
CAUTION:
Be careful not to damage engine coolant temperature sensor.
12. Remove water outlet, heater pipe, water bypass pipe and water connector.
INSTALLATION
Note the following, and install in the reverse order of removal.
 Securely insert each hose, and install clamp at a position where it does not interfere with the pipe bulge.
 When inserting water bypass pipe and heater pipe into water connector, apply neutral detergent to O-ring.
