REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) Remove the 3 drain plugs on the engine and radiator, and
drain the coolant.
(c) Close the 3 drain plugs.
Torque: 12.7 N´m (130 kgf´cm, 9 ft´lbf) for engine
2. REFILL WITH ENGINE COOLANT
(a) Slowly fill the system with coolant.
Capacity:
w/ Front heater: 14.8 liters (15.6 US qts, 13.0 Imp. qts)
w/ Front heater and rear heater:
15.3 liters (16.2 US qts, 13.4 Imp. qts)
NOTICE:
Do not use plain water alone.
HINT:

Use of improper coolants may damage the engine cooling
system.

Use ºToyota Super Long Life Coolantº or similar high qual-
ity ethylene glycol based non-silicate, non-amine, non-
nitrite, and non-borate coolant with long-life hybrid or-
ganic acid technology.

New Toyota vehicles are filled with Toyota Super Long
Life Coolant (color is pink, premixed ethylene glycol con-
centration is approximately 50 % and freezing tempera-
ture is -35°C (-31°F)). When replacing the coolant, Toyo-
ta Super long Life Coolant is recommended.

Observe the coolant level inside the radiator by pressing
the inlet and outlet radiator hoses several times by hand.
if the coolant level goes down, add the coolant.
If the coolant level goes down, add the coolant.
(b) Install the radiator cap.
(c) Bleed the cooling system.
(1) Start the engine, and open the heater water valve.
(2) Maintain the engine speed at 2,000 - 2,500 rpm,
and warm up the engine.
(d) Stop the engine, and wait until the engine coolant cools
down.
(e) Refill coolant into the reservoir until it is ºFULLº.
3. CHECK FOR ENGINE COOLANT LEAKS

(a) Procedures for test mode:
(1) Turn the ignition switch OFF.
(2) Check that the shift lever is in the P position, and
turn the steering wheel to the neutral position.
(3) Using SST, connect terminals Ts and E
1 of the
DLC1.
SST 09843-18020
(4) Start the engine.
(5) Check that the VSC TRAC warning light blinks.
HINT:
If the VSC TRAC warning light does not blink, inspect the VSC
TRAC warning light circuit and Ts terminal circuit (See page
DI-631 and DI-653).
Turn the steering wheel either to the left or right 450° or
more from the vehicle stationary condition, and turn back
the steering wheel to the straight ahead position.
(b) Keep the vehicle stationary on a level place for 1 sec. or
more.
(c) Check the yaw rate sensor.
Shift the shift lever to the D position and drive the vehicle
at a vehicle speed of approx. 5 km/h (3 mph), turn the
steering wheel either to the left or right 90° or more, and
maintain this angle until the vehicle has turned 180°.
Stop the vehicle and shift the shift lever to the P
position. Check that the VSC buzzer sounds for 3
sec.
If the VSC buzzer sounds, the sensor check is in normal
completion.
If the VSC buzzer does not sound, do the sensor check again.
If the VSC buzzer still does not sound, check the VSC buzzer
circuit, then do the sensor check again.
Trouble AreaSee page
VSC buzzer circuitDI-649
HINT:

Make a 180° turn. At the end of the turn, the direction of
the vehicle should be within 180°± 5° of its start position.

Do not spin the wheels.
(d) Read the DTC.
(1) Using SST, connect terminals Tc and E
1 of the
DLC1 or Tc and CG of the DLC3.
SST 09843-18020 or 09843-18040
(2) Read the number of times the VSC TRAC warning
light blinks.
HINT:

See the list of DTC shown on the next page.

If every sensor is normal, a normal code is output. (A cycle
of 0.25 sec. ON and 0.25 sec. OFF is repeated.)

(g) P position test:
Stop the vehicle on a grade (more than 5°) and after shifting into the P position, release the parking
brake. Then, check that the parking lock pawl holds the vehicle in place.
11. ADJUST SHIFT LEVER POSITION
When shifting the shift lever from the N position to other posi-
tions, check that the lever can be shifted smoothly and accu-
rately to each position and that the position indicator is not
aligned with the correct position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures.
(a) Loosen the nut on the shift lever.
(b) Push the control shaft fully rearward.
(c) Return the control shaft lever 2 notches to N position.
(d) Set the shift lever to N position.
(e) While holding the shift lever lightly toward the R position
side, tighten the shift lever nut.
Torque: 13 N´m (130 kgf´cm, 9 ft´lbf)
(f) Start the engine and make sure that the vehicle moves
forward when shifting the lever from the N to D position
and reverses when shifting it to the R position.
12. ADJUST PARK/NEUTRAL POSITION SWITCH

Check that the engine can be started with the shift lever
only in the N or P position, but not in other positions.
If it is not as stated above, carry out the following adjustment
procedures.

Loosen the park/neutral position switch bolt and set
the shift lever to the N position.

Align the groove with neutral basic line.

Hold in position and tighten the bolt.
Torque: 13 N´m (130 kgf´cm, 9 ft´lbf)

For continuity inspection of the park/neutral position
switch, see page DI-394.
13. CHECK IDLE SPEED
Idle speed (In N position and air conditioner OFF):
700 ± 50 rpm
