5.7. The sensor of temperature of cooling liquid - check and replacement
Attention! It is impossible to disconnect the sensor until the engine does not cool down.
1. If the sensor of temperature of cooling liquid does not work, at first it is necessary to check safety locks.
2. If the sensor of temperature shows excessively high or low temperature, it is necessary to warm up the engine.
6.3a the Sensor of temperature of cooling liquid (it is specified by an arrow) is usually located about the thermostat which is at an inlet collector.
6.3b On some models the sensor of temperature of cooling liquid (it is specified by an arrow) is located in the bottom of an inlet collector, behind the distributor.
3. If the sensor of temperature shows high temperature when the engine did not get warm yet, disconnect wires from the sensor (6.3a, 6.3b). If temperature drops are observed, then the sensor should be replaced. If the sensor shows high temperature, means wires are short-circuited.
4. If after warming up of the engine temperature sensor still does not function, and safety locks are checked, kill the engine. Disconnect a wire from the sensor and ground it on the engine case. Include ignition, without starting the engine. If the sensor shows high temperature, it should be replaced.
5. If temperature sensor still does not work, so it is faulty, or the chain can be opened.
6. When the engine completely cools down, disconnect a radiator casing, squeeze the top hose of a radiator and replace a cover.
7. Disconnect the sensor from electricity.
8. Prepare the new temperature sensor.
9. Install the new sensor.
10. Accurately insert the sensor and connect a plait of wires.
11. Add cooling liquid and start the engine. Check system for existence of leaks.
