The indicator of a cooling liquid

If the indicator of a cooling liquid starts to blink during movement, it is necessary to stop immediately.

 PERFORMANCE ORDER

  1. To check up level of a cooling liquid (the head cooling System) and if necessary to add cooling liquid or water.
  2. If the engine hot, and level of a cooling liquid corresponds to norm, it is necessary to check up, whether the electric fan of system of cooling works at the included ignition. If it costs, despite the heated engine, it is necessary to address to the list of malfunctions on the fan of system of cooling (the head cooling System).
  3. Last possibility: неиправен one of two gauges of this indicator (the following section see).

Search of malfunctions of the indicator of a cooling liquid

 PERFORMANCE ORDER

  1. Indicator check: at inclusion of ignition the indicator of a cooling liquid blinks for action check. If it does not occur:
  2. To check up a corresponding safety lock (head Kuzovnaja electrosystem).
  3. If it is serviceable, it is necessary to remove a combination of devices, to remove and check up the indicator.
  4. If the bulb is perfectly in order, it is necessary to check up a wire or to replace the minisystem block.
  5. Check of the temperature gauge in the motor block: if the indicator blinks even at (working) engine cold or having normal working temperature, that, probably, the temperature gauge is faulty.
  6. To separate the multicontact tip at the temperature gauge: the bulb should go out.
  7. Wire to the indicator of a cooling liquid to bring to "weight": the bulb should start blinking again.
  8. If so has occurred in both cases, means, the bulb is serviceable; that is it is necessary to search for the reason in the gauge or conducting. Or in the gauge of level of a cooling liquid.
  9. Check of the gauge of level of a cooling liquid in a broad tank:
  10. The gauge is established from below in a compensatory tank and rigidly connected with it.
  11. If the indicator blinks despite true level of a liquid, it is necessary to disconnect a wire from the gauge.
  12. If after that the blinking stops, it is necessary to clear the gauge in a tank or to replace a tank.
