Locating the Coolant Temperature Sensor
The coolant temperature sensor in a 2012 Dodge Ram 1500 can be found in different locations, depending on the year and engine model. To accurately locate the sensor, we have gathered information from various sources to provide you with the most reliable insights.
According to user experiences shared on a forum thread, the coolant temperature sensor of a 1998 Dodge Ram 1500 with a 5.9 engine is situated underneath or behind the alternator. Another user in the same discussion confirmed that it is located behind the alternator on the intake manifold, next to the thermostat housing.
In older models, such as those manufactured before 1997, the location of the sensor may differ. Some models have two sensors: one for the PCM (engine control module) and another for the temperature gauge and warning light. The sending unit sensor is usually positioned to the left of the thermostat housing, while the ECT (engine coolant temperature) sensor can be found just behind and to the right of the thermostat housing.
Table 1: Coolant Temperature Sensor Locations
| Model Year | Location |
|---|---|
| 1998 Dodge Ram 1500 (5.9 engine) | Behind the alternator on the intake manifold, next to the thermostat housing |
| Pre-1997 Dodge Ram 1500 | Two sensors: sending unit to the left of the thermostat housing, ECT sensor behind and to the right of the thermostat housing |
In newer models, generally from 1997 onwards, there is usually only one sensor that serves both the PCM and temperature gauge functions. This sensor is typically positioned to the left of the thermostat housing.
One user also noted that the coolant temperature sensor can be identified as a two-prong sensor. When replacing the sensor, it is recommended to use Teflon tape or hylamar on the threads to ensure a secure seal. Additionally, exercise caution when unscrewing the sensor to avoid any damage, and be prepared for a small amount of coolant loss during the replacement process.
Older Models (Pre-’97) Sensor Locations
If you own an older Dodge Ram 1500 model manufactured before 1997, there may be two coolant temperature sensors, each serving different purposes.
The first sensor, known as the sending unit, can be found to the left of the thermostat housing. It is responsible for providing information to the temperature gauge and warning light. The second sensor, called the Engine Coolant Temperature (ECT) sensor, is located just behind and to the right of the thermostat housing.
According to forum discussions, these locations have been confirmed by Dodge Ram 1500 owners. It’s essential to remember that this information specifically applies to older models, and the proper identification and replacement of the sensors are crucial for optimal performance of your vehicle.
| Coolant Temperature Sensor | Sensor Location |
|---|---|
| Sending Unit | To the left of the thermostat housing |
| Engine Coolant Temperature (ECT) Sensor | Just behind and to the right of the thermostat housing |
When replacing the sensors, it’s important to exercise caution to avoid breaking them. Some users recommended using Teflon tape on the threads for a secure fit, while others suggested using hylamar instead. Whichever method you choose, ensure that the threads are properly sealed to prevent any leaks.
It’s worth noting that during the replacement process, a small amount of coolant may be lost. It is recommended to have additional coolant on hand to top up the system if necessary. This will help maintain the proper functioning of the coolant temperature sensors and ensure your older Dodge Ram 1500 continues to run smoothly.
Newer Models (Post-’97) Sensor Location
If you own a newer Dodge Ram 1500 model manufactured from 1997 onwards, you will find a single coolant temperature sensor that handles both the PCM (engine control module) and temperature gauge functions. This sensor plays a crucial role in monitoring the engine temperature and sending the necessary signals to the PCM and temperature gauge.
The location of the coolant temperature sensor in these models is typically to the left of the thermostat housing. The sensor is situated on the intake manifold, providing easy access for maintenance or replacement. Its positioning ensures accurate temperature readings, allowing the PCM to make necessary adjustments for optimal engine performance.
To identify the coolant temperature sensor, look for a two-prong sensor in this location. This design is commonly found in newer Dodge Ram 1500 models, making it easier to differentiate from other components. However, exercise caution when handling or unscrewing the sensor to avoid any damage.
When replacing the coolant temperature sensor, it is recommended to use Teflon tape on the threads to prevent leaks and ensure a secure fit. Alternatively, some users advise using hylamar instead. Regardless of the method chosen, be mindful that some coolant may be lost during the replacement process. Take necessary precautions to minimize any spillage and refill the coolant as needed.

| 1997 onwards | To the left of the thermostat housing on the intake manifold |
Identifying the Coolant Temperature Sensor
When searching for the coolant temperature sensor in your 2012 Dodge Ram 1500, it’s important to know how to identify it among other engine components. The location of the sensor may vary depending on the year of the truck, but there are some general indicators to look out for.
One common characteristic of the coolant temperature sensor is that it is a two-prong sensor. This means it has two connectors on top, usually with wiring that leads to the engine control module (PCM). Keep an eye out for a small sensor with two prongs, as this is likely to be the coolant temperature sensor you’re looking for.
Another way to identify the sensor is by its placement within the engine compartment. In most cases, the coolant temperature sensor can be found near the thermostat housing. It is often located to the left of the thermostat housing, but make sure to check both sides to be certain.
| Year | Sensor Location |
|---|---|
| ’96 and older | To the left of the thermostat housing for sending unit sensor. Just behind and to the right of the thermostat housing for ECT (engine coolant temperature) sensor. |
| ’97 onwards | To the left of the thermostat housing. |
It’s worth noting that some owners have mentioned locating the coolant temperature sensor behind the alternator on the intake manifold. This may apply to certain models and engine configurations, so it’s best to refer to your specific vehicle’s manual or consult with a trusted mechanic for accurate information.
When replacing the coolant temperature sensor, it is recommended to use Teflon tape on the threads. This helps create a secure seal and prevent any leaks. However, some users have suggested using hylamar instead. Whichever method you choose, ensure that you are cautious when unscrewing the sensor to avoid breaking it. Additionally, keep in mind that some coolant may be lost during the replacement process, so be prepared to replenish the system if necessary.
Tips for Replacing the Coolant Temperature Sensor
