Compression pressure inspection
If the there is lack of power, excessive oil consumption or poor fuel economy, measure the compression
pressure.
1. Warm up the engine until the normal operating temperature becoming 80~95°C(176~203°F).
2. Remove the surge tank.
3. Remove the ignition coil connectors(B) and ignition coils.
4.Using a 16mm plug wrench, remove the 6 spark plugs.
5. Check cylinder compression pressure.
(1) Insert a compression gauge into the spark plug hole.
(2) Open the throttle fully.
(3) With the fully - open throttle in cranking, measure the compression pressure.
Always use a fully charged battery to get the engine speed of 250 rpm or more.
Repeat steps 1) through 3) for each cylinder.
This measurement must be done in as short a time as possible.
Compression pressure: 1,176.79kPa (12.0kgf/cm², 170.68psi) - 200 ~ 250rpm
Minimum pressure: 1,029.69kPa (10.5kgf/cm², 149.34psi)
Difference between cylinders: 98.07kPa (1.0kgf/cm², 14.22psi)
(4) If the compression pressure in 1 or more cylinders is lower than the specification above, pour a small amount
of engine oil into the cylinder through the spark plug hole, repeat the steps (1) through (3) for the cylinder and
measure the pressure again.
a. If adding oil increases the pressure up, the piston rings or cylinder bores might be worn or damaged.
b. If the pressure doesn't increase, a valve may be sticking or seating may be improper, or there may be
leakage from the gasket.
6. Reinstall the spark plugs.
7. Install the ignition coils and connect ignition coil connectors.
8. Install the surge tank.
VALVE CLEARANCE INSPECTION AND ADJUSTMENT
Inspect and adjust the valve clearance when the engine is cold (Engine coolant temperature : 20°C
±5°C(59~77°F)) and cylinder head is installed on the cylinder block.

5.Remove the fuel inlet hose(A) from the delivery pipe.
6.Disconnect the engine wiring harness connectors.
(1) Disconnect the No.1/No.2 knock sensor connectors(A,B), the oil pressure switch connector(C), the ignition coil
harness(D) and the No.1 VIS(Variable Induction System) connector(E).
(2)Disconnect the bank 1 front/rear O2 sensor connectors(A).
(3)Disconnect the injection connectors(A,B,C), the ground lines(D), the condensor connector(E) and the Ignition
coil connectors(F).

(9)Connect the No.1/No.2 knock sensor connectors(A,B), the oil pressure switch connector(C), the ignition coil
harness(D) and the No.1 VIS(Variable Induction System) connector(E).
23. Install the fuel inlet hose(A) from the delivery pipe.
24.Install the upper radiator hose(A) and lower radiator hose(B).
25.Install the intake air hose and air cleaner assembly.
(1) Install the intake air hose and air cleaner assembly(C).

5.Remove the under cover.
6.Drain the engine coolant.
7. Remove the upper radiator hose(A) and lower radiator hose(B).
8.Remove the transaxle oil cooler hoses(A/T vehicles only).
9. Remove the fuel inlet hose(A) from the delivery pipe.
10. Disconnect the engine wiring harness connectors.

INSTALLATION
Installation is in the reverse order of removal.
Perform the following :a. Adjust the shift cable.
b. Refill the engine with engine oil.
c. Refill the transaxle with fluid.
d. Refill the radiator with engine coolant.
e. Bleed air from the cooling system with the heater valve open.
f. Clean the battery posts and cable terminals with sandpaper assemble them, then apply grease to prevent
corrosion.
g. Inspect for fuel leakage.
After assembling the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for
approximately two seconds and fuel line pressurizes.
Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.

ON-VEHICLE INSPECTION
SPARK TEST
1. Remove the ignition coil connector(A).
Disconnect the iguition coil connector while pulling up tre connector lock.
2. Remove the ignition coil.
3. Using a spark plug socket, remove the spark plug.
4. Install the spark plug to the ignition coil.
5. Ground the spark plug to the engine.
6.Check is spark occurs while engine is being cranked.
To prevent fuel being injected from injectors while the engine is being cranked, remove the fuel pump(A) relay
from the fuse box.
Crank the engine for no more than 5 ~ 10 seconds.
7. Inspect all the spark plugs.
8. Using a spark plug socket, install the spark plug.
9. Install the ignition coil.
10. Reconnect the ignition coil connector.
