How To Change The Coolant Temperature Sensor

When your car starts to overheat, you may assume the worst. You might think that the problem is with the engine, or maybe something is wrong with the cooling system. But in many cases, the culprit is actually a faulty coolant temperature sensor. This sensor monitors the temperature of your engine’s coolant and alerts you when it falls outside of a certain range. When this happens, you may experience overheating and other problems. If you’re experiencing any of these issues and suspect that the coolant temperature sensor is the culprit, here are some steps to take to replace it yourself.
