Checking Drive BeltsNBS0000D
WARNING:
Be sure to perform this step when engine is stopped.
Make sure that the indicator (C) (notch on fixed side) of drive belt auto-tensioner is within the possible use
range (A).
NOTE:
Check the drive belt auto-tensioner indication when the engine is cold.
When new drive belt is installed, the indicator (C) (notch on fixed side) should be within the range (B) in
the figure.
Visually check entire drive belt for wear, damage or cracks.
If the indicator (C) (notch on fixed side) is out of the possible use range or belts is damaged, replace drive
belt.
Tension AdjustmentNBS0000E
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.

4. Remove electric throttle control actuator (bank1, bank2) as follows:
NOTE:
When removing only intake manifold collector, move electric throttle control actuator without disconnect-
ing water hose.
a. Drain engine coolant.
CAUTION:
Perform this step when engine is cold.
b. Disconnect water hoses from electric throttle control actuator. When engine coolant is not drained from
radiator, attach plug to water hoses to prevent engine coolant leakage.
CAUTION:
Do not spill engine coolant on drive belt.
c. Disconnect harness connector.
d. Loosen mounting bolts in reverse order as shown in the figure.
CAUTION:
Handle carefully to avoid any shock to electric throttle
control actuator.
Do not disassemble.
NOTE:
Figure shows electric throttle control actuator (bank1) viewed
from the air duct side.
Viewed from the air duct side, order of loosening mounting
bolts of electric throttle control actuator (bank2) is the same
as that of the electric throttle control actuator (bank1).
5. Disconnect vacuum hose, PCV hose and EVAP hose from intake manifold collector.
6. Remove EVAP canister purge volume control solenoid valve and EVAP tube assembly from intake mani-
fold collector.
