How long does it take to install a temperature sensor?
The actual process of replacing the coolant temperature sensor is extremely simple. However, the difficult work comes in the preparation of the cooling system – both before and after. Tip: This job should only be completed when the engine is cold and has not been running for a minimum of one hour.
What does the coolant temp sensor do on a Dodge Ram?
The coolant temp sensor (s) have a few jobs. They send a signal to the gauges so you can monitor engine temperature, they tell the radiator fans when to kick on or off, and they let the ECU know how warm the engine is so that it can fine-tune the fuel delivery to give you maximum performance as well as fuel efficiency.
Where are the sensors on a Dodge Ram?
On trucks with two sensors, the one on the left of the thermostat housing is the sending unit for the gauge, and the one behind and to the right sends signal to the ECU. Depending on the problem you are having, you will likely just change one or the other. Figure 1.
What should my coolant temperature sensor reading be?
You should have a reading of approximately 2000 ohms. Check the warm sensor in your engine. You should see a much lower reading on the ohm meter. If not, then it is not working correctly. Replacing the coolant temperature sensor is an easy process that anyone can do at home with some basic mechanic’s tools.
When did the coolant change on Dodge Ram?
If left unchecked, cooling problems can lead to series engine damage like warped heads. From 1994 to 1997, the Ram had two coolant temp sensors (CTS) to handle the different functions. In ’97, they began switching over to one multi-function CTS, and in ’98 and up they all had just one.

Where is the coolant temperature sensor located on a car?
The first item that needs to be completed after you compiled all of your tools and assets is to locate the coolant temperature sensor. In the image above, you can see that most coolant temperature sensors are located on the top, driver side of the engine. However, the location of this sensor may be different with your specific engine.
