Tip 1: How to change the gauge of inclusion of the fan

Fan, allowing to provide an additional air flow to cool the motor running, set in almost all cars.During the operation of the fan responsible special sensor , which is activated when reaching a certain temperature coolant.This sensor is consumables and requires replacement periodically.
you need
  • - screwdriver;
  • - the new sensor;
  • - set of wrenches;
  • - the capacity of the coolant;
  • - cotton gloves.
Guide
1
Drive the vehicle into the garage and shut off the engine.Allow the car to cool down.It is best to replace the morning on a cold motor.In no case do not try to replace the sensor just muffled car!You run the risk of burns from hot parts.Also during operation of the engine coolant temperature reaches a maximum.
2
Locate the sensor and inclusion fan in your car.To do this, read the manual of your vehicle.It should be specified the exact location of the sensor and as well as instructions for its replacement.
3
If no instructions, please visit the forum owners o
f your model cars.Surely someone has already changed sensor and shared his impressions about this procedure.
4
drain the coolant from the system.To do this, unscrew the cap on the radiator.On some models, you need to remove the battery to gain access to the drain throat.Do not drain the coolant to the ground!It is very poisonous and can cause irreparable damage to the environment.Try not to inhale the vapors when draining.
5
Disconnect from sensor pads and wires.Do not pull the cord, otherwise you risk damaging it.Grasp the housing block.
6
Remove sensor key size.Typically, you need a key to "30".Remove sensor connector.Look carefully the surface.
7
Check the sensor and .For this there are two options.The first consists of measuring the level of resistance at a certain temperature, but it is difficult.Therefore, you can simply connect to the sensor from the battery and a light bulb in series.The lower part of the sensor and drop in a pot of hot water.If the bulb lights up, defective sensor.If not - need to install a new one.

Tip 2: How to change the sensor fan

sensor inclusion fan on the radiator of the car need to be included starting a relay at certain times - when the coolant temperature reaches a specific level.When failure of the device to be replaced.
How to change the sensor fan
you need
  • - wrench;
  • - Screwdriver;
  • - copper pad
Guide
1
To change the fan sensor, pre-spend its verification.To do this, turn the ignition, then disconnect the sensor wires from it, feeding it, and connect them with each other.If after these manipulations fan stopped working - the reason for failure lies precisely in it, but if it is working again, the reason for failure is in the sensor, which should be replaced.
2
Pour the radiator by opening the drain plug in the bottom tank, coolant, remove the fan from the sensor connected to it the power wires.
3
Using a wrench, unscrew and remove the sensor from the radiator body.In that case, if it is very old, his face is not scrolled, it will be easier to use a spanner.
4
Next, install the new device is strictly in reverse order, but in order to provide better tightness between the sensor and the radiator fan put a seal ring made of copper.
5
Before installing a new device, it is advisable to check the suitability.Connect an ohmmeter to terminals output device, lower in a bowl with water and heat it.Household thermometer, measure the water temperature at which the sensor is included - iecontact closure occurs, which confirmed the ohmmeter.In operating the device contacts are closed when the water temperature in the range of 90-95 ° C, and they are no longer closed at temperatures between 82 to 87oS.
Note
fan sensors differ from each other on the temperature at which they work.For example, such devices are often mounted on the operating temperature is 92oS when the contacts and 87oS - when opening.When buying a new try to take the sensor is broken or a similar one that has a wide range of temperature adjustment.
