  2. If the engine too hot, and level of a cooling liquid normal, check up, whether enough powerfully rotates вязкостный the fan (the noise reminding work of the turbine at giving of gas?).
  3. The car with the electric fan: the fan, if the engine too hot rotates?
  4. The radiator fan does not work, despite the heated radiator.

Control bulb of a cooling liquid

 PERFORMANCE ORDER

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