Control bulb of cooling liquid

Cars without autocontrol system

If during movement the control bulb of cooling liquid starts to blink, at once stop:

 PERFORMANCE ORDER

  1. Check level of cooling liquid (head cooling System) and if it is necessary, small portions add cooling liquid or water. Be careful, opening a locking cover of system of cooling.
  2. If the engine too hot, and level of cooling liquid normal, check, whether enough the vyazkostny fan (the noise reminding operation of the turbine at supply of gas powerfully rotates?).
  3. The car with the electric fan: the fan, if the engine too hot rotates?
  4. The fan of a radiator does not work, despite the heated radiator.
  5. Last possibility: the general sensor of a control bulb and the indicator of temperature of cooling liquid is faulty.

Control bulb of cooling liquid

 PERFORMANCE ORDER

  1. Check of a control bulb: the control bulb blinks for functional control at ignition inclusion. If it is not present:
  2. Check the corresponding safety lock (head the Electrotechnical equipment).
  3. If it as it should be, dismantle the combined device, dismantle a control bulb and check.
  4. If a bulb as it should be, check a wire and/or replace/repair the combined device.
  5. Check of the sensor of temperature on the engine: if the control bulb blinks also at the cold engine or at working temperature of the engine (at the working engine!), that can be faulty the temperature sensor. About its check read in this chapter above in the section the Indicator of temperature of cooling liquid.
  6. The sensor of level of cooling liquid in a broad tank:
  7. The sensor is inserted into a broad tank from below and strongly connected to a tank.
  8. At a blinking bulb, despite the correct level of cooling liquid, disconnect sensor wires.
  9. If the blinking stops, clean the sensor inside in a tank or replace a tank.
