As a general rule, anyone, even the novice driver knows, or at least realizes the grave consequences of engine overheating. "Disease prevention is better than cure" - an old well-known postulate, but most motorists paid little attention when riding on the testimony of such an important instrument, as the coolant temperature sensor, all the attention, usually concentrating on the speedometer. Well even if this oversight be limited to boiling liquid, in which the motorist still pay attention. In no case, should not be in this situation, immediately begin to cool the engine block in cold water. The metal can simply not sustain a large temperature difference. The engine must cool themselves. But better, of course, operate vehicle in accordance with technical rules, the benefit that it takes so little - to monitor the instrument readings. Then do not have a pity to note that the new metal was scrap metal, and the engine is subject to, if not replaced, then a very high maintenance. Each driver must develop a stable rule - after a certain period of time to look at the readings coolant temperature. And, if the needle has left the operating range, you should stop immediately and look for the cause of change in temperature. When equipment car electric fan, a possible cause of overheating in the failure of the system fan control, which includes a temperature sensor, relay and fuse. Inspection begins with the simplest, namely the safety. The blessing on the cover of the fuse box clear pictures shown for any node is responsible or that box. If, when replacing a fuse, the fan did not work, turn to the temperature sensor. Find it is not difficult. This is the detail heat sink, which summarizes the electrical wires. Here are some wires and disconnect from the sensor and close to each other when the ignition key. Earned a fan? Hence, the reason is in the sensor and the path can be continued, despite the constantly running air cooling. If you attempt to insert a safety sensor and the fan turned out to be fruitless, the next object of study is the electric fan relay. It is also located in the fuse box. You have to remove it from the regular place and try to clean the contacts, if it does not work, try to jack jumper wire Coscom control contacts. The pin is usually marked on the lid of the box. It did not help and it? Then with the help of automotive lamps and wires need to try to find out whether a suitable power supply to the fan motor? If the bulb lights up and the food is, then he burned the motor. The reason, though rare, but the present. In this case, you should move in the direction of the SRT, small pieces, completely eliminating overheating, stop at the approach to the instrument needle danger zone. We'll have to make special stops, open the hood and wait patiently, but it's better than to look for scrap metal former once the engine's favorite car. Another reason for overheating of the engine - the thermostat. Ensure that it is not difficult to refuse. Engine is hot - cold radiator, so the thermostat does not open. As a general rule, failure is small, inexpensive parts may cause damage to such a complex device like a motor. It is always easier to replace them in time than to expose themselves as "pleasure" for a large renovation.
