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 the belt mid-
way between pulleys.

Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.

Measure belt tension with belt tension gauge (Commercial
Service Tool: BT3373-F or equivalent) at points marked
shown in the figure.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point.

Adjust if belt deflection exceeds the limit or if belt tension is not within specifications.
CAUTION:

When checking belt deflection or 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 deflection or tension without looseness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on the belt.
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 of used belt”.

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 tools.
2. Open radiator drain plug at the bottom of radiator, and remove
radiator cap.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
When drain all of engine coolant in the system, open water drain plugs on engine cylinder block.
Refer to EM-121, "
DISASSEMBLY" .
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-17, "
FLUSHING COOLING SYSTEM" . : 34.8 N·m (3.5 kg-m, 26 ft-lb)

10. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000
rpm with heater temperature controller set at several position between “COOL” and “WARM”.

Sound may be noticeable at heater unit.
11. Repeat step 10 three times.
12. If sound is heard, bleed air from cooling system by repeating step 3 through 6 until engine coolant level no
longer drops.

Clean excess engine coolant from engine.
FLUSHING COOLING SYSTEM
1. Fill radiator with water until water spills from the air relief hole, then close air relief plug. Fill radiator and
reservoir tank with water and reinstall radiator cap.
2. Run engine and warm it up to normal operating temperature.
3. Rev engine two or three times under no-load.
4. Stop engine and wait until it cools down.
5. Drain water from the system. Refer to MA-15, "
DRAINING ENGINE COOLANT" .
6. Repeat steps 1 through 5 until clear water begins to drain from radiator.

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 undercover (with power tool) when inspecting power steering oil pump belt.

Make sure that indicator (single line notch) of each automatic tensioner is within the allowable working
range (between three line notches).
NOTE:

Check the auto tensioner indication when the engine is cold.

When the 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 the belt.
Tension AdjustmentALS000GQ
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
