Prevention
Start works only after complete cooling of the engine.
Check
| PERFORMANCE ORDER |
| 1. In default the sensor at first check safety locks (see subsection 12.1). |
| 2. If later small time after engine start the sensor shows the overestimated temperature, be guided by subsection 1.9. |
| 3. If the sensor shows "Hot" condition ("hot") right after start-up of the cold engine, disconnect a wire from the sensor. On engines 4E-FE the sensor will screw sideways in a thermostat cover, and on engines 4A-FE and 7A-FE – in a branch pipe of the pump of cooling liquid. If the indication falls, the sensor replace. If the indication remains overestimated, the reasons can be short circuit on mass of a wire of the sensor, or malfunction of the sensor. |
| 4. If the sensor ceases to show temperature after complete warming up of the engine (about 10 minutes later after start-up), and safety locks are serviceable, arrive as follows. Stop the engine, disconnect a wire from the sensor and by means of an additional piece of a wire close a sensor wire on well cleared site of the engine. Include for short time ignition, but the engine do not start. If the sensor shows now "Hot", the sensor replace. |
5. If indications of the sensor are absent, break in chains, or malfunction of the sensor can be the reason. |
|
Replacement
| PERFORMANCE ORDER |
| 1. Merge cooling liquid (see subsection 2.8.4). |
| 2. Disconnect the conducting socket from the sensor. |
| 3. A deep face head, or a rozhkovy key turn out the sensor. |
| 4. Wrap the new sensor and reliably tighten. To condense a sensor carving with hermetic it is not allowed, as violation of contact of the case of the sensor with weight is possible. |
| 5. Attach the conducting socket, fill in liquid, start the engine, check existence of leaks and operation of the engine. |
