Hyundai Santa Fe: Engine Mechanical System / Repair procedures
Compression Pressure Inspection |
•
|
If the there is lack of power, excessive oil consumption or
poor fuel economy, measure the compression pressure.
|
|
1. |
Warm up and stop engine.
Allow the engine to warm up to normal operating temperature.
|
2. |
Disconnect the injector extension connector (A).
|
3. |
Remove ignition coils (A).
|
4. |
Remove spark plugs.
Using a 16mm plug wrench, remove the 4 spark plugs.
|
5. |
Check cylinder compression pressure.
(1) |
Insert a compression gauge into the spark plug hole.
|
(2) |
Fully open the throttle.
|
(3) |
While cranking the engine, measure the compression pressure.
• |
Always use a fully charged battery to obtain
engine speed of 200 rpm or more.
|
|
|
(4) |
Repeat steps (1) through (3) for each cylinder.
• |
This measurement must be done in as short a
time as possible.
|
|
Compression pressure :
1088.53 kPa (11.1 kgf/cm², 157.88 psi)
Minimum pressure :
941.43 kPa (9.6 kgf/cm², 136.54 psi)
Difference between each cylinder :
100 kPa (1.0 kgf/cm², 15 psi) or less
|
|
(5) |
If the cylinder compression in 1 or more cylinders is low, pour
a small amount of engine oil into the cylinder through the spark
plug hole and repeat steps (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. |
Reinstall spark plugs.
|
7. |
Install ignition coils.
|
8. |
Connect the injector extension connector and ignition coil connectors.
|
9. |
Some DTC's may exist after the inspection test and may need to be manually
cleared with diagnostic tool.
