What is Coolant Temperature Sensor?
The coolant temperature sensor is located near the thermostat housing on the engine block. It monitors the temperature of the engine coolant and sends a signal to the vehicle’s computer. The computer uses this information to adjust the fuel mixture and ignition timing. If the coolant temperature sensor is not working properly, it can cause engine drivability problems such as poor fuel economy and engine misfires.
The Function of Coolant Temperature Sensor
The function of the coolant temperature sensor is to inform the vehicle computer (PCM or ECU) about the engine temperature. This information is used in a variety of functions, from emissions control to ignition timing adjustments, and also for determining when to turn on fans or lights .This sensor often gets overlooked because it’s rarely the source of issues and often does not directly affect or even impact the function of a vehicle.
The coolant temperature sensor is typically located on or near the engine in an accessible place, making it easy to access for replacement if needed.
However, as mentioned, since most vehicles have more than one engine temperature sensor and they don’t all send information to the computer, drivers don’t often realize when one goes bad.
The sensor is typically a two wire sensor that does not require much power and can get very hot or very cold to operate properly. In many vehicles it’s inside the thermostat housing (which also houses the water pump) where it has access to engine coolant and air from outside the engine compartment.

Now you know that this is an engine component required for the correct and efficient operation of your Chevy 5.3 Vortec Engine. This component is called the coolant temperature sensor, or sometimes a coolant temperature switch. It is usually screwed into the cylinder head or intake manifold near the outlet from the thermostat housing. Its purpose is to sense the coolant temperature and relay this information to the powertrain control module (PCM) so that it can properly adjust the spark timing, fuel delivery, transmission shift schedule, as well as other parameters based on the engine’s operating conditions.
However, if this component fails or gets damaged, your car may suffer from a host of different symptoms that can be very difficult and even confusing to diagnose if you’re not familiar with what this component does. For example, if you notice that your engine is overheating but the cooling system appears to be working properly, it could be that the coolant temperature sensor has failed and needs to be replaced.
Now, the coolant temperature sensor is not an expensive component and can be easily replaced by anyone who has basic automotive knowledge. The only thing you have to make sure of is that you get a high quality one, since it’s such a vital part of your engine system. If this sensor fails or becomes damaged, then your car may not run or drive as well as it used to.
Chevy Coolant Temperature Sensor Symptoms
There are a few telltale signs that your Chevy coolant temperature sensor is failing. One of the most common symptoms is an overheating engine. If the sensor isn’t working properly, it won’t be able to regulate the engine’s temperature, causing it to run hot.
Another symptom of a failing coolant temperature sensor is erratic engine behavior. If the sensor is sending incorrect information to the engine computer, it can cause the engine to run Rough or stall unexpectedly.
Finally, a faulty coolant temperature sensor can cause poor fuel economy. Since the sensor affects the way the engine runs, it can cause the engine to use more fuel than necessary.
What to Do in Case of Coolant Temperature Sensor Failure?
The coolant temperature sensor, or CTS, is designed to monitor the engine temperature and the rate at which it is cooling down. The sensor has a great impact on how your car runs since its information is used by various systems in making important decisions. As such, if your Chevy 5.3 coolant temperature sensor fails, there are a couple of things you need to do.
The first thing you should do is check the sensor for damage or wear. The most common symptom of a failing coolant temperature sensor is that your engine and its electronics start malfunctioning when the vehicle reaches normal operating temperatures. Check whether this happens on hot days, cold mornings, and especially when you’re climbing steep hills or driving for a long time. Start by replacing the faulty coolant sensor immediately to prevent further damage.
Another thing you can do is set the engine running and watch if it runs smoothly or fights against itself as though there’s not enough oxygen in the system. When this happens, another cause of a failing coolant temperature sensor is a bad thermostat. If this is the case, replace it immediately or your engine might overheat and fail.
If your car runs fine even when overheated, chances are that water leakage in the coolant system caused the sensor to fail. In this case, you should check whether there’s any leaking coolant before taking it to a mechanic for repair.
Luckily, you can easily replace the coolant temperature sensor by yourself. You need to know the location of this component in your car and remove it with a ratchet wrench. Always check that all parts are installed properly and that there’s no leakage before you start your engine. With this done, you can be sure that your engine will run smoothly and efficiently, providing you with the best possible driving experience.
Choosing the Chevy 5.3 Coolant Temperature Sensor
