4.6.3. The gauge of temperature of a cooling liquid

The gauge is mounted in a back part of a head of cylinders (from outside a flywheel).

The gauge represents the thermoresistor fed with stabilised pressure, and is included in an index chain.


1. In process of heating of a liquid the current through the gauge increases also an arrow of the index should deviate to the right. It is necessary to replace the faulty gauge.
2. At incorrect indications of temperature check up work of other devices.
3. If devices do not work, check up a feed circuit of the panel of devices.
4. In case of erroneous indications of all devices replace a voltage stabilizer (it is mounted on the printed-circuit board of the panel of devices).
5. If the temperature index arrive as follows is faulty only.
6. In case of the underestimated indications disconnect a wire from the gauge and concern weights.
7. If at the included ignition of the marksman will deviate, the gauge is faulty.
8. If indications do not change, remove the panel of devices (subsection 14.9 see) and check up conducting from the gauge to the index and an index food.
9. If a food moves also conducting is serviceable, the index is faulty.
10. In case of the overestimated indications disconnect a wire from the gauge.
11. If on the cold engine of the marksman will deviate in the left part of a scale the gauge is faulty.
12. If indications have not changed, check up other part of a chain.


On some cars for access to the gauge it is required to disconnect or take aside hoses and conducting.

1. Disconnect the battery from weight.
2. On the cooled down engine merge a part of a liquid to thermoswitch level.
3. Disconnect a thermoswitch socket.
4. Cautiously turn out the thermoswitch, remove a sealant (if it is provided).


1. Clear the thermoswitch and put on a carving hermetic.
2. Replace a sealant (if it is provided).
3. Further assemblage is carried out upside-down.
