How to Fix Temperature Gauge Problem On Chevy Trucks?

Temperature gauges are necessary tools that are used to measure the temperature of your engine under all circumstances. If the gauge of your Chevy truck starts acting up, fix it as soon as possible.

If you want to fix the gauge, you need to first locate the problem or area of issue. Once located screw, detach all parts and replace the older faulty part with a newer gauge or gear. Screw them back afterward. 

So, have you thought about fixing the temperature gauge yet? Chevy trucks rely on their impregnable engine for the entire energy input. That is why temperature gauges are important instruments. 

Why Is the Chevy Silverado Temperature Gauge Not Working?

If your temperature gauge starts working up, there could be many different reasons behind it. Some of them are major problems within the engine, while others include temporary setbacks. 

Below, we have compiled a list of the different reasons that cause your temperature gauge to not work properly. 

Faulty Thermostat

Faulty or damaged thermostats are one of the most common reasons why your truck’s temperature gauge might not work properly. 

The thermostat is responsible for controlling the current amounts in the engine cooler depending on the internal temperature. With this, you will notice the thermostat showing only minor changes over periods.

Faulty Temperature Sensors

Temperature sensors are responsible for sensing the temperature of the engine and providing the data to the thermostat. 

If the sensor breaks, the thermostat will not be able to control the right amount of voltage. As a result, the gauge will not show the driver the right temperature. 

Broken Wires

Torn or faulty wires are one of the most common reasons due to why your temperature gauge could refuse to work properly. Torn wires could implicate the entire coolant system and thus the gauge.

Broken Gauge

The last point on our list is another of the most common issue that most drivers can face. If the gauge or any of its parts gets broken, it’s inevitable that your Silverado will provide you with the right temperatures. 

The only way to fix it back is to replace the entire temperature gauge with a new one. 

Tools You Required To Fix Temperature Gauge On A Chevy Truck

If you are going to fix the temperature gauge of your Chevy truck, there are quite a lot of tools that you will be required to use. 

We have listed some of these tools below. However, do note that it is not necessary that you use all of these tools. Additionally, you can also use alternate ones as long as the purpose is met. 

  • Wrenches
  • Screwdriver
  • Extra Screw
  • Working Lights
  • Pliers
  • New Thermostat or sensors as required

How to Fix the Temp Gauge On A Chevy Truck?

Now that you have a basic idea of what tools you will be required to work with and what exactly you will be working with, we can move on to guide you with this task.

Below, we have compiled the step-by-step guide that you will be following to fix the temperature gauge. 

Step 1: Safety Measures

The first step is the preparatory step, where you will ensure your safety. You can wear gloves and remove any energy source from the truck. 

Make sure that the battery is de-sparked so that you do not get shocked. Also, drain the engine coolant of the liquid inside.

Step 2: Use Scanners

Use temperature scanners of your choice to take measurements of the surrounding temperature. If it doesn’t match with the reading on the gauge, we can be sure that there is indeed a problem there. 

Step 3: Locate the problem

Before you can fix the problem, you need to find out what exactly the problem is. Look for broken wires or faulty thermistors. If all of them are okay, the problem probably lies with the gauge meter itself.

Step 3: Fix the problem

Make use of pliers and screwdrivers to de-attach the old gauge. Start with removing the radiator cap and disconnecting all the connecting sensors. 

Replace the old gauge with a new one and connect the sensors back. Make sure that the coolant plugs have been plugged together securely before testing the gauge. 

If required, use new wires to replace the old ones that might be torn or worn out. You can do the same thing for the sensors. 

Step 4: Test Out

Once you have reconnected the gauge to the vehicle and all of its sensors, test out to check for any anomalies. Make use of the scanner to scan the surrounding temperature so that it matches the gauge reading.

Take a test drive and check for the temperature again. Use the scanner to double-check the gauge. 


While fixing the temperature gauge on your Chevy truck isn’t a task you should neglect, you should make your own safety to be the primary priority. 

This is because fixing the temperature gauge is a very technical issue that requires a lot of skill. Besides, it is also a process that consumes a moderately high amount of time.

Therefore, if you are thinking that it would be better for a professional mechanic to do the task for you, you are more than welcome to hire one. But do note that the labor cost will be high so expect to spend a lot!
