SSANGYONG Y200
PREHEATING SYSTEM (DIESEL
ENGINE)
General information
The preheating system consists of control relay, coolant
temperature sensor and glow plugs.
1. Preheating time - control relay.
Control relay functions as followings :
•
Switching of preheating current.
•
Indication of preheating finish.
•
Control of preheating sequence.
YAD1E010 •
Indication of fault.
2. Coolant temperature sensor.
Coolant temperature sensor senses coolant's
temperature and signals it to the preheating relay
continuously.
3. Glow plug
The glow plug parts are housing with M12 ´ 1.25
thread and heating pin in housing. It is connected
in a parallel circuit with the specified voltage of
11.5 V.
The heating element has a heating coil and a
control coil and they are connected in series.

4. Current and temperature of glow plug
•
Current of glow plug
While the preheating system operates, current
of about 30 A flows in each glow plug and
temperature of heating coil rises very fast.
Due to the rise of temperature, the resistance
of control coil increases therefore the current is
controlled to about 8 - 15A and that protects
the glow plug from overheating.

•
Temperature of glow plug
The temperature of the glow plug reaches up to
900 °C (1,652 °F) after about 9 seconds and up
to 1,050 °C (1,922 °F) after 30 seconds.
