Checking Tightening Torque
Checking should be performed while engine is cold.

Checking Drive Belts
INSPECTION
+Before inspecting the engine, make sure the engine has
cooled down; wait approximately 30 minutes after the engine
has been stopped.
+Visually inspect all belts for wear, damage, or cracks on
contacting surfaces and edge areas.
+When measuring deflection, apply 98 N (10 kg, 22 lb) at the
.marked point.
+When checking belt deflection immediately after
installation, first adjust it to the specified value. Then,
after turning the crankshaft two turns or more, re-adjust
to the specified value to avoid variation in deflection
between pulleys.
+Tighten idler pulley lock nut and measure deflection
without looseness.

Alternator water pump belt Adjusting bolt on alternator
Power steering pump belt Adjusting bolt on idler pulley
CAUTION:
+When a new belt is installed as a replacement, adjust it
to the value specified under ªNewº accommodations
because of insufficient adaptability with pulley grooves.
+If the belt deflection of the current belt is out of the
ªLimit for re-tighteningº, adjust to the ªAdjusted valueº.

+When checking belt deflection immediately after
installation, first adjust it to the specified value. Then,
after turning crankshaft two turns or more, re-adjust it to
the specified value to avoid variation in deflection
between pulleys.
+Make sure the belts are fully fitted into the pulley
grooves during installation.
+Handle with care to avoid smearing the belts with oil or
cooling water etc.
+Do not twist or bend the belts with strong force.

1. Loosen idler pulley lock nut (A).
2. Turn adjusting bolt (B) to adjust.
+Refer to MA-3011, ªInspectionº for adjustment values.
3. Tighten lock nut (A).
Nut A:
: 30.4 - 39.2 Nzm (3.1 - 3.9 kg-m, 23 - 28 ft-lb)

1. Loosen adjuster lock nut (C).
2. Loosen alternator fixing nut (D) (Rear).
3. Turn adjusting bolt (E) to adjust.
+Refer to MA-3011, ªInspectionº for adjustment values.
4. Tighten nut (C) and nut (D) in this order.
Nut C:
: 19.6 - 23.4 Nzm (2.0 - 2.3 kg-m, 15 - 17 ft-lb)
Bolt D:
: 45.1 - 59.7 Nzm (4.6 - 6.0 kg-m, 34 - 44 ft-lb)
Changing Engine Oil
WARNING:
+Be careful not to burn yourself, as the engine oil is hot.
+Prolonged and repeated contact with used engine oil
may cause skin cancer; try to avoid direct skin contact
with used oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Put vehicle horizontally.
2. Warm up engine, and check for oil leakage from engine com-
ponents.
3. Stop engine and wait more than 10 minutes.
4. Remove drain plug and oil filler cap.
5. Drain oil and refill with new engine oil.
Oil Specification and Viscosity:
+API CD, CE, CF or CF-4 (Except for Europe)
+API CF-4 or ACEA 98-B1 (For Europe)
Refer to MA-3008, ªRECOMMENDED FLUIDS AND LUBRI

Always use the dipstick to determine when the proper
amount of oil is in the engine.
6. Check oil level as follows.
a. Start engine and check area around drain plug and oil filter
for oil leakage.
b. Run engine for a few minutes, then turn it off. After more than
10 minutes, check oil level.
