Replacing the coolant temperature sensor - methods, cost

The task of the coolant temperature sensor is to provide the necessary information to the power unit. They are used to determine the correct air/fuel mixture and to turn on the radiator fan. Therefore, if this part fails, the data will be falsified. As a result, the drive may be damaged. For this reason, the replacement of the coolant temperature sensor is necessary and must be carried out immediately. What to do to avoid serious damage? What are the symptoms of sensor damage? How to replace the coolant temperature sensor? Look at yourself!

Replacing the coolant temperature sensor - symptoms of a malfunction

Before you learn how to replace the coolant temperature sensor, you need to know what the symptoms of failure of this part look like. If the element is faulty, the controller will not receive any information about the parameters of the coolant itself. In this case, your car will most often go into emergency mode. The engine will receive a "conditional" dose of fuel so as not to overload it. As a driver, you will experience a significant drop in power and performance. 

Replacing the coolant temperature sensor in a car may also be necessary if fuel consumption has increased sharply recently. Also indications for evaluating the condition of the sensor are higher idle speeds or problems with starting. 

Before you start reading how to replace a coolant temperature sensor, make a proper diagnosis!

When is it not necessary to replace the coolant temperature sensor?

Perform diagnostics before replacing the coolant temperature sensor. Thanks to him, you will know whether the repair will really bring the desired results. The above symptoms do not always lead to the need to replace the coolant temperature sensor. So how do you know what action is needed? 

This part is distinguished by the so-called relative change in resistance design. This is why resistance decreases as temperature increases and voltage decreases. As a result, you can send information to the controller. If you do not know if you need to replace the coolant temperature sensor, follow these steps!

Replacing the coolant temperature sensor in a car - when is it necessary?

Use a device called a multimeter to check if your vehicle's coolant temperature sensor needs to be replaced.. It serves to check the resistance at the terminals. Put one of the wires on the first contact, and the second probe on the third. If the motor temperature is 20°C, the resistance should be 2000-3000 ohms. If the indication is different, you will know that the coolant temperature sensor needs to be replaced.

How to replace the coolant temperature sensor step by step?

Wondering how to replace the coolant temperature sensor? Fixing this error is very easy. All you have to do is remove the damaged element and install a new one in its place. Accessing the part itself can be a problem, depending on what kind of car you have. However, by replacing it yourself, you can save a little on visiting a mechanic. 

you know Jhow to replace the coolant temperature sensor. And what is the cost of such a service from a mechanic?

Replacing the coolant temperature sensor on the mechanics - how much does it cost?

Despite the fact that replacing the coolant temperature sensor is a trivial task, not everyone has the time and desire to do it on their own. If you are one of these people, then you can contact a specialist. Replacing the coolant temperature sensor at the mechanic costs about 60-8 euros

Replacing the coolant temperature sensor is often overlooked. Meanwhile, the failure of this part can lead to more serious problems. Don't put it off to avoid further repair costs!
