2012 SSANGYONG NEW REXTON stop start

After installing to the engine, replenish a small
amount of clean engine oil to the inlet before
connecting the oil inlet pipe of the
turbocharger.
Do not let any metal debris enter when
installing to the engine.
The engine oil may be provided to the
compressor housing if you rapidly operate the
turbocharger with excessive revolutions
immediately after installing to the engine. 5.

Do not raise the engine rpm rapidly after
starting the engine.
Do not raise the engine rpm rapidly after
renewing the engine oil and filter element.
Do not stop the turbocharger rapidly after
operating at high engine speed. -

2. OPERATION
Glow plug is installed in the cylinder head. It enhances the cold starting performance and reduces the
exhaust gas during cold starting.
1. Pre-heating
2. Post-heating during engine running If normal communication with the ECU is established 2 seconds after the power is supplied to the IGN
terminal from the battery, the ECU supplies the battery voltage to glow plugs.
The post-heating controlled by ECU begins its operation after engine start The time for pre-heating is controlled by the ECU. -
The time for post-heating controlled by the ECU starts from engine start. This improves the idling
conditions and reduces the emission and noise. -
2) System Check

Forced Shut-off of Relay
Check for short in each glow plug
Check for open due to over-voltage in each glow plug

2. INSPECTION
1) Cautions During Driving
The following lists cautions to take during test drive and on the turbocharger vehicle, which must be
considered during the operation.
It's important not to drastically increase the engine rpm starting the engine. It could make rotation at
excessive speed even before the journal bearing is lubricated and when the turbocharger rotates in
poor oil supply condition, it could cause damage of bearing seizure within few seconds.
If the engine is running radically after replacing the engine oil or oil filter brings poor oil supply
condition. To avoid this, it's necessary to start off after idling the engine for about 1 minute allowing oil
to circulate to the turbocharger after the replacement.
When the engine is stopped abruptly after driving at high speed, the turbocharger continues to rotate
in condition where the oil pressure is at '0'. In such condition, an oil film between the journal bearing
and the housing shaft journal section gets broken and this causes abrasion of the journal bearing due
to the rapid contact. The repeat of such condition significantly reduces life of the turbocharger.
Therefore, the engine should be stopped possibly in the idle condition. 1.
2.
3.
After string for long period of time during winter season or in the low temperature condition where the
fluidity of engine oil declines, the engine, before being started, should be cranked to circulate oil and
must drive after checking the oil pressure is in normal condition by idling the engine for few minutes.
