Hyundai Venue: General Information / Repair procedures
Compession Pressure Inspection |
• |
If the there is lack of power, excessive oil consumption or
poor fuel economy, measure the compression pressure.
|
|
1. |
Make sure the oil in the crankcase is of the correct viscosity and at
the correct level and that the battery is correctly charged. Operate
the vehicle until the engine is at normal operating temperature. Turn
the ignition switch to the OFF position.
|
2. |
Remove the engine center cover.
|
3. |
Remove the ignition coil (A).

|
4. |
Remove the spark plugs.
Using a 16mm plug wrench, remove the 4 spark plugs.
|
5. |
Check the cylinder compression pressure.
(1) |
Insert a compression gauge into the spark plug hole.

|
(2) |
Set the throttle plate in the wide-open position.
|
(3) |
While cranking the engine, measure the compression pressure.
• |
Always use a fully charged battery to obtain
engine speed of 250rpm or more.
|
|
|
(4) |
Repeat step 1) through 3) for each cylinder.
• |
This measurement must be done in as short time
as possible.
|
|
Compression pressure
Standard : 1225.83kPa (12.5kg/cm², 177.79psi) (200-250
rpm)
Minimum : 1078.73kPa (11.0kg/cm², 156.46psi)
Difference between each cylinder :
98kPa (1.0kg/cm², 14psi) or less
|
|
(5) |
If the cylinder compression in one or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat step 1) through 3) for cylinders
with low compression.
•
|
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or damaged.
|
•
|
If pressure stays low, a valve may be sticking or seating
is improper, or there may be leakage past the gasket.
|
|
|
6. |
Install the spark plugs.
|
7. |
Install the ignition coil (A).

|
8. |
Install the engine center cover.
Tightening torque :
7.8 - 11.8 N.m (0.8 - 1.2 kgf.m, 5.8 - 8.7 lb-ft)

Other information:
ALWAYS use the Floor Mat Anchors to attach the front floor mats to the vehicle.
The anchors on the front floor carpet keep the floor mats from sliding forward.
WARNING
Do not overlay additional mats or liners over the floor mats. If using All
Weather mats, remove the carpeted floor mats before installing them...
