PRECAUTIONS
3. Attach liquid gasket tube to t
ube presser (commercial service
tool).
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44
.
4. Apply liquid gasket without breaks to the specif ied location with the specified dimensions.
 If there is a groove for the liquid gasket application, apply liquid gasket to the groove.
 As for the bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of this manual.
 Within five minutes of liquid gasket application, install the mat-
ing component.
 If liquid gasket protrudes, wipe it off immediately.
 Do not retighten after the installation.
 Wait 30 minutes or more after installation before refilling engine with engine oil and engine coolant.

Checking Drive BeltsINFOID:0000000001325766
WARNING:
Be sure to perform when 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 auto tensioner for alternator, water pump and A/C
compressor belt, while it is found on the fixed side for power steering oil pump belt.
 Visually check entire belt for wear, damage or cracks.
 If the indicator is out of allowable wo rking range or belt is damaged, replace belt.
Tension AdjustmentINFOID:0000000001325767
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.

REMOVAL
Alternator, Water Pump and A/C Compressor Belt
1. Remove air duct (inlet). Refer to EM-173, "Component".
2. With box wrench, and while securely holding the hexagonal part in pulley center of auto tensioner, move wrench handle in the
direction of arrow (loosening direction of tensioner).
CAUTION:
 Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.
 Do not loosen the hexagonal part in center of drive belt auto-tensioner pulley (Do not tu rn it clockwise). If turned
clockwise, the complete dri ve belt auto-tensioner must be
replaced as a unit, including the pulley.
