Checking Drive BeltsALS000H0
WARNING:
Be sure to perform when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on belt midway between pulleys.
Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.
Measure the belt tension with belt tension gauge (Commercial
service tool: BT3373-F or equivalent) at points marked
shown in the figure.
When measuring the deflection, apply 98 N (10 kg, 22 lb) at
the marked point.
Adjust if the belt deflection exceeds the limit or if the belt ten-
sion is not within specifications.
CAUTION:
When checking the belt deflection or the tension immediately after installation, first adjust it to
the specified value. Then, after turning crankshaft two turns or more, re-adjust to the specified
value to avoid variation in deflection between pulleys.
Tighten idler pulley lock nut by hand and measure the deflection or the tension without loose-
ness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.
Drive Belts Tension AdjustmentALS000H1
CAUTION:
When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.
When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.
When checking belt deflection or tension immediately after installation, first adjust it to the speci-
fied value. Then, after turning crankshaft two turns or more, re-adjust to the specified value to
avoid variation in deflection between pulleys.
When installing belt, make sure that it is correctly engaged with pulley grooves.
Keep engine oil, working fluid and engine coolant away from belt and pulley grooves.
Do not twist or bend belt excessively.

1. Remove front engine undercover with power tool.
2. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to EM-123, "

4. Loosen oil filler cap and then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer. Refer to EM-30, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil. Engine oil specification and viscosity:
Refer to MA-12, "

Engine oil capacity (Approximate):
Unit: (US qt, lmp qt)
CAUTION:
When filling engine oil, do not pull out oil level gauge.
The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
Always use oil level gauge to determine the proper amount of engine oil in engine.

Checking Drive BeltsALS000GP
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 each 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
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 working range or belt is damaged, replace belt.
Tension AdjustmentALS000GQ
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
