Technical characteristics
The indicator of temperature of a cooling liquid
|
|
The gauge of the indicator of level of a cooling liquid (2) is established below in a broad tank (1) cooling liquids. |
The indicator of temperature of a cooling liquid functions the same as the indicator of quantity of fuel in a fuel tank. The current from plus receives the device at the included ignition, connection to weight provides the temperature gauge on the engine. This gauge represents variable resistance which in process of heating passes more current, therefore on the tool moves more current and the marksman deviates further. In one case two different gauges of temperature are united. First, the gauge of temperature of a cooling liquid of system of injection (contacts 1 and 3) and, secondly, the gauge about which here it was told (contacts 2 and 4).

Council: At too heat of a cooling liquid the blinking red alarm bulb in addition joins. Work of this bulb the microprocessor of the combined device operates. The bulb also flashes at fall of level of a cooling liquid. In cars with system of the autocontrol instead of a lamp there is a red symbol Kuhlmittel – the Cooling liquid. |
Infringements in work
- Wrong indications of the indicator of temperature of a cooling liquid (more often at simultaneously inexact indications of quantity of fuel) allow to draw a conclusion on malfunction of the microprocessor in the combined device.
- Absence of indication can be a consequence of malfunction of the gauge of temperature or the device.
- At correct indication and simultaneously blinking emergency signal the cause of defect can be also in the gauge of the indicator of level of a cooling liquid in a broad tank.
