4.1.9. Sensor of temperature of cooling liquid

GENERAL INFORMATION

Arrangement of sensors of temperature of cooling liquid of the index of a temperaturya of the control unit

The sensor of temperature of the index of temperature (1) on combinations of devices and the sensor of temperature of the control unit (2) are located under an inlet collector on the right side.

Check

PERFORMANCE ORDER
1. If the index of temperature does not work, check fuses in an electric chain.
2. If the index of temperature shows high temperature at start of the cold engine, disconnect a wire from temperature sensor. If the index of temperature shows the low temperature of the engine, replace the sensor of temperature of cooling liquid.
3. If the index still shows high temperature, check a condition of an electric chain from the sensor to the index or the index of temperature of cooling liquid.
4. If the index of temperature of cooling liquid does not show any temperature after warming up of the engine and a safety lock in the normal state, disconnect a wire from the sensor of temperature and connect it to the mass of the car. For a short time include ignition, without starting the engine.
5. If the index of temperature shows high temperature of the engine, replace the sensor of temperature of cooling liquid. If the arrow of the index remains on the place, check a condition of an electric chain or serviceability of the index of temperature of cooling liquid.

Replacement

PERFORMANCE ORDER
1. Prepare the new sensor of temperature of cooling liquid for installation it in the engine, having applied a thin film of sealant on a sensor carving.
2. Disconnect the electric socket from the sensor of temperature of cooling liquid.
3. Unscrew the sensor of temperature of cooling liquid.
4. As soon as possible screw in the new sensor and tighten it the required moment. Connect the electric socket to the sensor and add cooling liquid in the cooling system.
