MAINTENANCE
COOLANT LEVEL CHECK
To check level, lift hood and look at “see-through” coolant reser-
voir tank.
It is not necessary to remove radiator cap to check coolant level.
When engine is cool, check coolant level in reservoir tank (1).
A normal coolant level should be between FULL mark (2) and
LOW mark (3) on reservoir tank (1).
If coolant level is below LOW mark (3), remove reservoir tank cap
(4) and add proper coolant to tank to bring coolant level up to
FULL mark (2). Then, reinstall cap (4) and align match marks (5)
on tank and cap (4). WARNING:
Do not remove radiator cap to check engine coolant level; check coolant visually at the see-through
coolant reservoir.
Coolant should be added only to reservoir as necessary.
As long as there is pressure in the cooling system, the temperature can be considerably higher
than the boiling temperature of the solution in the radiator without causing the solution to boil.
Removal of the radiator cap while engine is hot and pressure is high will cause the solution to boil
instantaneously and possibly with explosive force, spewing the solution over engine, fenders and
person removing cap. If the solution contains flammable anti-freeze such as alcohol (not recom-
mended for use at any time), there is also the possibility of causing a serious fire.
WARNING:
To help avoid danger of being burned :
do not remove reservoir tank cap while coolant is boil-
ing, and
do not remove radiator cap while engine and radiator
are still hot.
Scalding fluid and steam can be blown out under pres-
sure if either cap is taken off too soon.
NOTE:
If proper quality antifreeze is used, there is no need to
add extra inhibitors or additives that claim to improve
system.
They may be harmful to proper operation of system,
and are unnecessary expense.
When installing reservoir cap, align arrow marks on
reservoir and cap.

6K-2 EXHAUST SYSTEM
GENERAL DESCRIPTION
The exhaust system consists of an exhaust manifold, three-way catalytic converter (TWC) in catalyst case,
exhaust pipes, a muffler and seals, gasket and etc.
The three-way catalytic converter is an emission control device added to the exhaust system to lower the levels
of Hydrocarbon (HC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx) pollutants in the exhaust gas.
MAINTENANCE
At every interval of periodic maintenance service, and when vehi-
cle is raised for other service, check exhaust system as follows:
Check rubber mountings for damage, deterioration, and out
of position.
Check exhaust system for leakage, loose connection, dent
and damage.
If bolts or nuts are loosened, tighten them to specified
torque.
Refer to “GENERAL DESCRIPTION”.
Check nearby body areas damaged, missing, or misposi-
tioned part, open seam, hole connection or any other defect
which could permit exhaust fumes to seep into vehicle.
Make sure that exhaust system components have enough
clearance from underbody to avoid overheating and possible
damage to passenger compartment carpet.
Any defect should be fixed at once. WARNING:
To avoid the danger of being burned, do not touch the
exhaust system when the system is hot. Any service on
the exhaust system should be performed when the sys-
tem is cool.

EXHAUST MANIFOLD
REMOVAL AND INSTALLATION
Refer to Section 6A1 for removal and installation procedures of exhaust manifold.
INSPECTION
Check gasket and seal for deterioration or damage.
Replace them as necessary.
EXHAUST PIPE
REMOVAL AND INSTALLATION
For replacement of exhaust pipe, be sure to hoist vehicle and observe WARNING under “MAINTENANCE” and
the following.
Tighten bolts and nuts to specified torque when reassembling. Refer to “GENERAL DESCRIPTION” for
location of bolts and nuts.
After installation, start engine and check each joint of exhaust system for leakage. CAUTION:
Exhaust pipe have three way catalytic converter in it, it should not be exposed to any impulse.
Be careful not to drop it or hit it against something.
