How to Fix the Thermostat
The main function of the thermostat is fast
car warm in cold conditions and protection of the motor from overheating. On
failure of the thermostat can be found by looking at the instrument panel.
Coolant Temperature Sensor arrow will go into the forbidden red sector and in
the winter the car interior is unusually long time to warm up.
If the arrow in the forbidden sector you
are dealing with the closing of the temp
control switch, when the coolant is forced to circulate in a small
circle. Engine overheating of the bulk of the heat remains in the engine. In
the second case, you see the opposite picture. Due to the constantly closed thermostat
contrary lacks warmth and therefore you face fuel consumption. A faulty
thermostat will have to be removed, but only after it has been drained coolant.
Now, you should remove it from dirt,
limescale and to fix the hole in the valve. But check the thermostat before. To
do this, put it in a saucepan with water and begin to heat on a hot plate,
previously having prepared a thermometer with a scale designed for a
temperature of over 100gradusov C. During the test, you need to fix the
temperature at which the valve opens, and what if it turns out the hole size.
Navigate to the temperature value should be marked on the body of the thermostat.
At VAZ it is usually 81-85 degrees, and in some cars - 92-93 degrees.
There is another kind of test of the
thermostat - in size, depending on the degree of heat. To do this, you should
be armed with a caliper and measure the distance between points in the cooled
and heated state. The difference in measurements is usually not less than 7 mm.
Wait until the thermostat to cool down, and check that the valve is fully
closed. If you find that the thermostat is faulty, do not attempt to repair it,
and go to the nearest store and buy new parts.
If the store will not appear thermostat for
your car, you should know that you can do without it. Take a piece of thin
plastic, cut a circle out of it and do it in a few holes, and then put it
simple device to place the thermostat. As a result of the circulation of a
large circle, and will be difficult to resume the supply of warm water in the
cabin heating system, as well as to ensure that the engine operating
temperature. BTW, you can select the temperature
controlled switch at Banggood for high quality and reasonable prices.
