Temperature sensor (Thermistor)
The thermistor is located on the thermostat housing, adjacent to
the high coolant temperature switch.
The thermistor must be installed in the thermostat housing in the
portlocatednearesttothecylinderhead.(Seetheguretothe

torque: 30 Nm.
Glow plug controller relay with coolant temperature sensor
To avoid white smoke generation at cold start-up, post-heating is
maintained for approximately 5 sec. after starting.
