1. Inspect for cracks, fraying, wear or oil adhesion. Replace if
necessary.
The belts should not touch the bottom of the pulley groove.
2. Check drive belt de¯ection by pushing on the belt midway
between pulleys.
Adjust if belt de¯ections exceed the limit.

Changing Engine Oil
WARNING:
+Be careful not to burn yourself, as 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. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Remove oil ®ller cap and drain plug.
3. Drain oil and ®ll with new engine oil.
Oil grade: CCMC PD1 or PD2
Viscosity:
See ``RECOMMENDED FLUIDS AND
LUBRICANTS'', MA-9.
Re®ll oil capacity (approximate):
Without oil ®lter change
6.4!(5-5/8 Imp qt)
With oil ®lter change
5.8!(5-1/8 Imp qt)
CAUTION:
+Be sure to clean and install oil pan drain plug with washer.
Drain plug:
:29-39Nzm (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
+The re®ll capacity changes depending on the oil tempera-
ture and drain time; use these valves as a reference and be
certain to check with the dipstick when changing the oil.

Checking Exhaust System
Check exhaust pipes, muffler and mounting for improper
attachment, leaks, cracks, damage, loose connections, cha®ng and
deterioration.
Checking Clutch Fluid Level and Leaks
If ¯uid level is extremely low, check clutch system for leaks.
Checking Clutch System
Check ¯uid lines and operating cylinder for improper attachment,
cracks, damage, loose connections, cha®ng and deterioration.
Checking M/T Oil Level and Leaks
Never start engine while checking oil level.
1. Check manual transmission for leakage.
2. Check oil level.

Limited-slip differential gear
+ Use only approved or recommended limited-slip differential
gear oil.
+ Limited-slip differential identi®cation.
(1) Lift both rear wheels off the ground.
(2) Turn one rear wheel by hand.
(3) If both rear wheels turn in the same direction simultaneously, vehicle is equipped with limited-slip differential.
Checking Front Wheel Bearing Grease
+Check that wheel bearings operate smoothly.
+ Check front wheel bearings for grease leakage and water or
dust entry.
+ Replace front wheel bearings or front wheel bearing grease if
wheel bearings do not turn smoothly.

Repacking Front Wheel Bearing and Axle Joint
Grease
FRONT WHEEL BEARING GREASE
Apply multi-purpose grease sparingly to the following parts:
+Threaded portion of spindle
+Contact surface between wheel bearing washer and outer
wheel bearing
+Grease seal lip
+Wheel hub (as shown at the left)
AXLE JOINT GREASE
+Drain approximately 2 liters (1-3/4 Imp qt) of differential oil.
+Remove knuckle spindle.
+Slightly pull out axle and repack axle joint with recommended
grease.
Refer to FA section.
Checking Free-running Hub Grease
Check free-running hub grease for leakage and water or dust entry.
Checking Water Entry in Knuckle Flange
+Check for water entry in knuckle ¯ange by removing one bolt
of lower knuckle ¯ange bearing cap and probing with a suitable
thin bar.
+After checking, be sure to reinstall the bolt to a tightening torque
of 30 to 40 Nzm (3.1 to 4.1 kg-m, 22 to 30 ft-lb).
Checking Brake Fluid Level and Leaks
If ¯uid level is extremely low, check brake system for leaks.

Checking Power Steering Fluid and Lines
+Check ¯uid level with engine off.
+Check ¯uid level with dipstick on reservoir cap. Use ``HOT''
range at ¯uid temperatures of 50 to 80ÉC (122 to 176ÉF). Use
``COLD'' range at ¯uid temperatures of 0 to 30ÉC (32 to 86ÉF).
CAUTION:
+Do not over®ll.
+Recommended ¯uid is Automatic Transmission Fluid type
``DEXRON
TMIII'' or equivalent.
+Check lines for improper attachment, leaks, cracks, damage,
loose connections, cha®ng or deterioration.
+Check rack boots for accumulation of power steering ¯uid.
Checking Steering Damper
Check steering damper for damage and oil leakage.
Checking Steering Gear Box and Linkage
STEERING GEAR
+Check gear housing and boots for looseness, damage or
grease leakage.
+Check connection with steering column for looseness.
STEERING LINKAGE
+Check ball joint, dust cover and other component parts for
