The index of temperature of cooling liquid

Fig. 2. The scheme of verification of the index of temperature of cooling liquid

1–X1 socket;
2–storage battery;

3–MLT-2 resistor (resistance 68, 180 and 910 Ohm);
4–X2 socket.

The index of temperature of cooling liquid 37.3807 works together with the sensor of temperature TM-106-10 screwed in a head of the block of cylinders. In the sensor the thermoresistor changing the resistance depending on temperature is established.

To check the sensor it is possible an ohmmeter. The serviceable sensor at temperature of liquid of 20-25 °C (the arrow of the index of temperature is in the scale beginning) should have resistance 1400 … 1900 Ohm, and at 80 °C (an arrow on border of green and white zones) – 100 … 110 Ohm.

The sensor not folding and to repair is not subject (see. Replacement of sensors of the index of temperature and a signaling device of an overheat of cooling liquid).

For verification of the index of temperature we remove a combination of devices (see. Removal of a combination of devices, replacement of lamps). We collect the scheme shown on fig. 2.

At resistance of the resistor of 68 Ohm of the shooter of the device should be in the middle of a red zone, at 180 Ohm – at the beginning of a green zone, and at 910 Ohm – at the beginning of white.

In a head of the block the TM sensor 111-02 signaling devices of an overheat of cooling liquid is in addition established. The sensor should work at liquid temperature increase to 104–109 °C.
