Checking Drive BeltsINFOID:0000000001328909
WARNING:
Be sure to perform when the engine is stopped.
 Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.
 Remove front engine undercover with power tool when inspecting power steering oil pump belt.
 Make sure that indicator (single line notch) of eac h auto tensioner is within the allowable working range
(between three line notches).
NOTE:
 Check auto tensioner indication when engine is cold.
 When new drive belt is installed, the range should be “A”.
 The indicator notch is located on the moving side of the tensioner for alternator, water pump and A/C com-
pressor belt, while it is found on the fi xed side for power steering oil pump belt.
 Visually check entire belt for wear, damage or cracks.
 If the indicator is out of allowable working range or belt is damaged, replace belt.
Tension AdjustmentINFOID:0000000001328910
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Changing Engine CoolantINFOID:0000000001328911
WARNING:
 To avoid being scalded, do not change engine coolant when engine is hot.
 Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressu re. Then turn radiator cap all the way.
 Be careful not to allow engine coolant to contact drive belts.

A/T fluid level will be greatly affected by temper ature as shown in figure. Therefore, be certain to
perform operation while checki ng data with CONSULT-III.
a. Connect CONSULT-III to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
c. Read out the value of “ATF TEMP 1”.
7. Recheck A/T fluid level at A/T fluid temperatures of approximately 65 °C (149 °F) using “HOT” range on A/
T fluid level gauge.
CAUTION:
 When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.
 To check A/T fluid level, inser t the A/T fluid level gauge
until the cap contacts the en d of the A/T fluid charging
pipe, with the A/T fluid level gauge reversed from the nor-
mal attachment conditions as shown.
8. Check A/T fluid condition.  If ATF is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.
 If ATF contains frictional material (clutches, bands, etc.), replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-13
(for
VQ35DE) or CO-40
(for VK45DE) and AT-13, "A/T Fluid
Cooler Cleaning".
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
10. Tighten level gauge bolt.
