Drain Plug
13. TRANSFER OIL
(Check oil level)
Check each component for evidence of leakage, and-check
the oil level by removing the filler the oil is
it is necessary to replace it with new oil.
1.With the vehicle parked at a level place, remove filler,
2. Check that the transfer oil level is at the portion
of the filler plug hole.
3. Check to be sure that the transfer oil is not
dirty, and that it has a suitable viscosity.
(Change oil) 1. Remove transfer drain plug.
2. Drain oil.
3. Tighten drain plug to specified torque.
Specified torque: 32 Nm (24
4.Remove filler plug and fill with specified oil till the. level
comes to the lower portion of filler-plug hole.
Specified oil:
API classification SAE or
Quantity: 0.5 qt.)
5. Tighten filler plug to specified torque.
Specified torque: 32 Nm (24
14. ENGINE COOLANT (Change)
Check the cooling system parts, such asradiator, heater,
and oil cooler hoses, thermostat and connections fo r leakage
and damage.
CHANGING COOLANT
1.Drain the engine coolant by removing the drain plug and
then the cap.

2.For non-turbo, remove the ‘drain plug from
block to drain engine coolant.
For turbo, remove the water hose from the water pip e
assembly (C) to do so.
3.
4.
5.Remove the reserve tank to drain the coolant.
When the engine coolant has drained, pour in water from
the cap to clean the engine coolant line.
For non-turbo, install the drain plug to the cylind er block.
For turbo, install the water hose to pipe assembly

8.
Securely tighten the radiator drain plug.
Install the reserve tank.
9.
Slowly pour the engine coolant into the mouth of th e
radiator until the radiator is full, and pour also into the
reserve tank up to the FULL line.
Recommended antifreeze:
LONG-LIFE COOLANT (Part No. 0103044)
or high quality ethylene-glycol antifreeze coolant)
Quantity 7.0
(7.4 qts.)
Install the cap securely.
Start the engine and warm the engine until the the rmostat
opens. (Touch the radiator hose with your hand to c heck
that warm water is flowing.)
11. After the thermostat opens, race the engine at 3,000
3 times.
12. After the engine is stopped, wait until the eng ine has
cooled down, and then remove the cap to check the
level of the liquid. If the level is low, repeat th e operation
from step 9.
Lastly, if the level does not drop, fill the conden se tank
with coolant up to the FULL line.
15. DISC BRAKE PADS (Check for wear)
Check for fluid contamination and wear. Replace com plete
set of pads if defective.
Caution
The pads for the right and left wheels should be re placed
at, the same time. Never “split” or intermix brake pad
sets.
All four pads must be replaced as a complete set.
Thickness of lining (A) Limit: 2.0 mm

l e a k s )
1.Remove the brake drum and check of brake
shoe lining for wear. Check the automatic brake adj usting
system by hand to see if it operates smoothly.
Also see if the gears are in proper mesh with each other.
To assure smooth operation, apply a thin coat of
multipurpose grease to the friction surface of adju ster
and link shaft.
