Engine Coolant Temperature Sensor Guide for the 2013-2016 Dodge Dart
Is your Dart overheating, running poorly, or showing a check engine light? Your coolant sensor could be the problem.
- A faulty ECT sensor can cause serious issues like overheating, poor fuel economy, and a check engine light on your Dart.
- Replacement is a simple DIY job for most owners, requiring basic tools and less than an hour.
- The sensor is located on the thermostat housing, but the exact position varies slightly between the 1.4L, 2.0L, and 2.4L engines.
- While budget parts are available, using a quality OEM (Mopar) or premium aftermarket brand like Delphi is recommended for this critical sensor.
Symptoms of a Failing Coolant Temperature Sensor in a Dodge Dart
When the coolant temperature sensor in a 2013-2016 Dodge Dart starts to fail, it can send incorrect signals to the engine's computer. This can cause a variety of noticeable problems. One of the first things you'll likely see is the Check Engine Light on your dashboard. You might also experience the engine overheating, or conversely, the temperature gauge might drop to its lowest reading while a warning message says the engine is too hot. Other common signs include a decrease in fuel mileage, black smoke from the exhaust, and the engine running rough or stalling.

When it comes to replacing the ECT sensor on your Dart, you have options ranging from the original Mopar part to a wide variety of aftermarket brands. For a critical component like this, quality matters.
- OEM/Premium Aftermarket: Mopar is the original equipment manufacturer and offers a direct fit and factory-grade reliability, though often at the highest price. Premium aftermarket brands like Delphi have a strong reputation for quality, often built to OE specifications, and are a reliable choice. Many owners and mechanics recommend sticking with OEM or top-tier aftermarket parts for critical sensors to avoid premature failure.
- Trusted Aftermarket: Brands like Standard Ignition (SMP) and Dorman are widely available and offer a balance of price and quality. They are often a direct replacement and a reliable solution for many drivers.
- Budget-Friendly Options: While there are many lower-cost brands available, their long-term reliability can be uncertain. For a sensor that plays a key role in engine health and performance, saving a few dollars on a budget part might lead to more problems down the road.
Pro Tip: Location Varies by Engine
The Dodge Dart was offered with three different engines (1.4L Turbo, 2.0L, and 2.4L). The location of the ECT sensor can vary. On the 2.4L "Tigershark" engine, the sensor is located on the driver's side of the engine, above the thermostat housing. 🎬 See the exact sensor location on the 2.4L engine. On the 1.4L Turbo, it is also located on the thermostat housing but can be more difficult to access. Always confirm the location on your specific engine before beginning work.

Frequently Asked Questions
Where is the coolant temperature sensor located on my Dodge Dart?
The location depends on your engine. For the 2.4L engine, it's on the driver's side, on top of the thermostat housing. For the 1.4L Turbo, it's also on the thermostat housing. For the 2.0L, it is in a similar position. It's a small, two-wire sensor that threads into the cooling system.
Is it difficult to replace the ECT sensor myself?
For a moderately experienced DIYer, this is a very feasible job. The main steps involve partially draining the coolant, disconnecting the electrical connector, and unscrewing the old sensor with a deep socket (usually 19mm). The difficulty is rated as low, and it typically takes under an hour.
🎬 Follow this step-by-step guide to replace the sensor yourself.Do I need to drain the coolant to replace the sensor?
Yes, you should drain at least some of the coolant before removing the old sensor. If you don't, coolant will spill out of the sensor port when it's removed. It's best to drain the coolant when the engine is completely cold to avoid burns.
Are there any recalls for the Dodge Dart coolant sensor?
Our search found no specific recalls for the engine coolant temperature sensor on the 2013-2016 Dodge Dart. However, there was a recall (NHTSA #N32) for some 2013 Darts with the 1.4L engine for engine stalling in cold temperatures, which required a software update to the engine computer.
