4. CHECK AND INSPECTION
1) Cylinder
(1) Compression pressure test
Specified value ▶
Compression ratio16.5 : 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.
Measurement ▶
Warm the engine up to normal operating temperature (80°C).
Disconnect the fuel rail pressure sensor connector to cut off the fuel injection.
Remove the air cleaner duct and glow plugs. -
-
-
Place the diagram sheet to compression
pressure tester and install it into the plug
hole. 1. 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. -

Water
separator
(2) Di engine and its expected problems and remedies can be caused by
water in fuel
System supplement against paraffin separation ▶
In case of Diesel fuel, paraffin, one of the elements, can be separated from fuel during winter and then
can stick on the fuel filter blocking fuel flow and causing difficult starting finally. Oil companies supply
summer fuel and winter fuel by differentiating mixing ratio of kerosene and other elements by region
and season. However, above phenomenon can be happened if stations have poor facilities or sell
improper fuel for the season. In case of DI engine, purity of fuel is very important factor to keep internal
preciseness of HP pump and injector.
Accordingly, more dense mesh than conventional fuel filter is used. To prevent fuel filter internal
clogging due to paraffin separation, SYMC is using fuel line that high pressure and temperature fuel
injected by injector returns through fuel filter to have an effect of built-in heater (see fuel system).
System supplement and remedy against water in fuel ▶
As mentioned above, some gas stations supply fuel with excessive than specified water. In the
conventional IDI engine, excessive water in the fuel only causes dropping engine power or engine
hunting. However, fuel system in the DI engine consists of precise components so water in the fuel can
cause malfunctions of HP pump due to poor lubrication of pump caused by poor coating film during
high speed pumping and bacterization (under long period parking). To prevent problems can be
caused by excessive water in fuel, water separator is installed inside of fuel filter. When fuel is passing
filter, water that has relatively bigger specific gravity is accumulated on the bottom of the filter.
Water drain from water separator ▶
If water in the separator on the fuel filter exceeds a certain level, it will be supplied to HP pump with
fuel, so the engine ECU turns on warning lamp on the meter cluster and buzzer if water level is higher
than a certain level.
Due to engine layout, a customer cannot easily drain water from fuel filter directly, so if a customer
checks in to change engine oil, be sure to perform water drain from fuel filter.
To separate the water from the fuel filter,
remove the fuel filter assembly first.

2. MAINTENANCE
1) Level Check
Park the vehicle on a level ground and apply the parking brake. Stop the engine and wait more than 5
minutes.
Pull out the dipstick and wipe it with a clean cloth. Reinsert it all the way.
Pull out it again and check the oil level.
The oil level should be between the maximum (Max) mark and minimum (Min) mark on the oil
dipstick. Oil should be replenished before the level goes below the minimum mark. -
-
-
Operating vehicle with insufficient amount of oil can damage the engine. Make sure the engine oil
level is correct and add oil if necessary.
2) Replenishment
If the level gets to the lower point, open the filler cap on top of the cylinder block and add the genuine
oil without exceeding the level of the upper mark.
Recheck the oil level after 5 minutes.
Regularly check the engine oil level and add Ssangyong genuine engine oil if necessary.
Clean the dipstick with clean cloth so that any foreign materials cannot get into the engine.
The oil should not go above the upper mark on the dipstick.
The engine oil may be consumed more if the engine is new. -

1) Coolant Level Check
Park the vehicle on level ground and apply the parking brake. Stop the engine and wait until it is
cooled down.
The coolant level should be between the MAX and MIN mark on the coolant reservoir.
Check the coolant level. If the level is below the “MIN” mark, immediately add coolant. 1.
2.
Scalding hot coolant and steam could be blown out under pressure, which could cause serious
injury. Never remove the coolant reservoir cap when the engine and radiator are hot.
Avoid any direct contact of the coolant to the painted body of the vehicle. -

(3) Starting with jumper cable
If the battery is weak or terminated, the battery from another vehicle can be used with jumper
cables to start the engine.
Connecting order ▶
The positive (+) terminal of the discharged battery
The positive (+) terminal of the booster battery
The negative (-) terminal of the booster battery
Connect one end of the other jumper cable to the body of the discharged vehicle, such as the
engine block or a front towing hook. 1.

Starting ▶
Prepare a set of jumper cables.
Place another vehicle that has the same 12 V of power near to the discharged vehicle.
Switch off all electrical accessories for the discharged vehicle.
Apply the parking brake and shift the transaxle to the P position (automatic transaxle) or neutral (N)
position (manual transaxle).
Connect the jumper cables.
Try to start the discharged vehicle while accelerating the engine rpm in the booster vehicle.
Attempt to start the engine with the discharged battery.
After starting the engine, carefully disconnect the jumper cables in the reverse sequence of
connection. 1.
