3. CHECK AND INSPECTION
1) Cylinder
(1) Compression pressure test
Specified value ▶
Compression ratio
16.5 : 1
Test conditionat normal operating temperature (80˚C)
Compression pressureStandard32 bar
Minimum18 bar
Differential limit between cylindersMaximum 3 bar
The compression pressure test is to check the conditions of internal components (piston, piston ring,
intake and exhaust vale, cylinder head gasket). This test provides current engine operating status.
Before cranking the engine, make sure that the test wiring, tools and persons are keeping away from
moving components of engine (e.g., belt and cooling fan).
Park the vehicle on the level ground and apply the parking brake.
Do not allow anybody to be in front of the vehicle. -

(2) Cylinder pressure leakage test
If the measured value of the compression pressure test is not within the specifications, perform the
cylinder pressure leakage test.Specified value ▶
Perform this test in the sequence of firing order.
Do not test the cylinder pressure leakage with wet type test procedure. (do not
inject the engine oil into the combustion chamber) -
-
Test condition: normal engine operating
temperature (80˚C)Specified value
Whole engine below 25%
at valve and cylinder head gasket below 10%
at piston ring below 20%

3) Oil Filter Module
The oil filter module consists of lubrication system, cooling system and some mechanical devices as
below.
System Components
Supplementary devices Power steering pump (HPS), Alternator, A/C compressor
Belt drive Belt tensioner, Idle pulley
Cooling Water pump, Thermostat, Cooler housing and Pipes
Lubrication Oil filter, Oil cooler (except coolant pipes)

3. LUBRICATION
1)Anti-friction
The oil makes a thin film on the surface of sliding components to reduce the wear due to friction.
2)Cooling
The friction makes the heat on the components. The oil absorbs the heat and radiates it or cools it down.
3) Sealing
The piston ring on the piston seals the cylinder. The oil gets into the clearance in piston ring to secure
the sealing for compression pressure and combustion gas.
4) Anti-corrosion
The oil generates the thin film on the surface of components to prevent the material from contacting with
air, water and corrosive gas.
5) Cleaning
The oil transfers the residue of material due to friction, oxidized substance, and carbonized substance
while circulating in the engine by oil pump.

3. CAUTIONS
If 100% of anti-freeze is added, the water pump vane can be damaged and thermal conductivity can
be decreased resulting in poor circulation in the cooling system which leads to overheated engine.
Use of non-recommended coolant could cause damage to the cooling system and overheating of the
engine.
Opening the coolant reservoir cap while the engine is running or hot can cause burns by hot steam o
r
water.
To open the coolant reservoir cap, wrap the cap with a wet towel or thick cloth after the engine is
cooled down sufficiently.
If cool water is added to the heated engine, the engine or radiator can be deformed.
The anti-freeze in the coolant can damage the painted surface, so avoid the contact of the coolant to
the painted body.
The anti-freeze and water should be mixed in proper mixture ratio. Never add only water when
adding coolant.
If the anti-freeze content is too low, the coolant can be frozen while the engine can be overheated if
anti-freeze content is too high. -
