THE GENERAL DATA

The temperature gauge informs the management equipment on engine temperature. Depending on this temperature the diaphragm regulator establishes its position. In case of damage of the gauge of temperature there can be difficulties at engine start at low temperature as the diaphragm will not be completely closed.

PERFORMANCE ORDER

1) remove a plug from the gauge of temperature and measure its resistance. At temperature +20 ° With it should equal 2000–3000 Ohm

2) connect a plug to the temperature gauge, start the engine and warm up it to normal working temperature

3) muffle the engine, repeat measurement of resistance which at temperature +90 ° With should equal 200–300 Ohm

Changes of resistance depending on temperature are presented on the schedule.

Resistance of the gauge

It is in details possible to make check of the gauge of temperature, placing it in a vessel with water and gradually warming up it. At the moment of heating of water to the corresponding temperature, measure resistance of the gauge.
In case of difference in the measured sizes, it is necessary to replace the temperature gauge.
