Removal and installation/check of the sensor of temperature of cooling liquid

The sensor of temperature of cooling liquid should be checked if the cold engine is badly started or works with interruptions. The sensor of temperature of cooling liquid is in dependence of year of release and the engine or on a reverse side of the engine, or in an inlet collector.

Removal

 PERFORMANCE ORDER

  1. To disconnect the plug of the sensor of temperature of cooling liquid.
  1. To unscrew temperature sensor. To substitute a pure vessel and to collect the following cooling liquid.

Check

 PERFORMANCE ORDER

  1. To suspend temperature sensor in the container with water and to slowly heat water.
  1. To measure temperature sensor resistance by an ohmmeter. For this purpose to connect one plug of an ohmmeter to the case, other plug of an ohmmeter to the sensor plug.
Temperature Resistance in Ohm
- 20 °C 14,2 — 17,8
20 °C 2,2 — 2,7
40 °C 1,0 — 1,3
60 °C 0,50 — 0,65
80 °C 0,29 — 0,35

Installation

 PERFORMANCE ORDER

  1. To install temperature sensor with new laying and to screw 25 Nanometers with effort.
  2. To fill in cooling liquid.
  3. To warm up the engine and to leave to idle, the radiator fan will not turn on yet. To double-check the level of cooling liquid.
