Search of malfunctions of the indicator of cooling liquid

PERFORMANCE ORDER

Indicator check: at ignition inclusion the indicator of cooling liquid blinks for action check. If it does not occur:
To check the corresponding safety lock (head Body electrosystem).
If it is serviceable, it is necessary to remove a combination of devices, to remove and check the indicator.
If a bulb as it should be, it is necessary to check a wire or to replace the minisystem block.
Check of the temperature sensor in the motor block: if the indicator blinks even at (working) engine cold or having normal working temperature, that, possibly, the temperature sensor is faulty.
To separate the multicontact tip at the temperature sensor: the bulb should go out.
Wire to the indicator of cooling liquid to bring to "weight": the bulb should start blinking again.
If so occurred in both cases, means, the bulb is serviceable; that is the reason should be looked for in the sensor or conducting. Or in the sensor of level of cooling liquid.
Check of the sensor of level of cooling liquid in a broad tank:
The sensor is established from below in a compensatory tank and rigidly connected with it.
If the indicator blinks despite true level of liquid, it is necessary to disconnect a wire from the sensor.
If after that the blinking stops, it is necessary to clear the sensor in a tank or to replace a tank.
