Checking Drive BeltsELS001BP
WA RN ING:
Be sure to perform when the engine is stopped.
1. Remove air duct and resonator assembly (inlet) when inspecting drive belt.
2. Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range
“A” (between three line notches) as shown.
NOTE:
Check the auto tensioner indication when the engine is cold.
When the new drive belt is installed, the range should be as shown.
The indicator notch is located on the moving side of the auto tensioner.
3. Visually check entire belt for wear, damage or cracks.
4. If the indicator is out of allowable working range or belt is damaged, replace the belt. Refer to EM-12,
"DRIVE BELTS" .
DRIVE BELT TENSION
There is no manual drive belt tension adjustment. The drive belt tension is automatically adjusted by the auto
tensioner.
Changing Engine CoolantELS001BQ

To avoid being scalded, never change the coolant when the engine is hot.
Wrap a thick cloth around the cap to carefully remove the cap. First, turn the cap a quarter of a
turn to release any built-up pressure, then push down and turn the cap all the way to remove it.
DRAINING ENGINE COOLANT
1. Turn ignition switch ON and set temperature control lever all the way to HOT position or the highest tem-
perature position. Wait 10 seconds and turn ignition switch OFF.
