The coolant temperature sensor on a 2008 Dodge Grand Caravan is located in the engine block near the thermostat housing. It typically has two wires connected to it and is usually held in place with a single bolt. The sensor should be easy to access once you open up the hood of your vehicle and locate the thermostat housing since it’s usually within an inch or two of that component.

You’ll also need to disconnect any wiring harnesses that are connected to it before attempting to remove it from its mounting location. Once removed, installation of a new one simply requires reversing these steps and reconnecting all associated wiring harnesses.

The coolant temperature sensor on a 2008 Dodge Grand Caravan is located in the lower radiator hose. It is designed to measure the temperature of the engine’s coolant so that it can then be used by your vehicle’s computer to adjust fuel and spark timing, as well as other parameters such as idle speed and air/fuel mixture. It is important to periodically inspect this part for any signs of wear or damage, as a faulty coolant temperature sensor can lead to serious engine problems.

Where are Coolant Temp Sensors Located?

Coolant temperature sensors are an integral part of the cooling system in any vehicle. They are responsible for detecting and monitoring changes in the engine coolant temperature, which is important to ensure optimal engine performance and prevent overheating. Generally speaking, a typical coolant temp sensor is located near the thermostat housing or cylinder head on most vehicles.

It’s usually mounted into a threaded hole with either 2 or 3 terminals running to it or connected via a plug-in connector. The exact location will vary depending on make and model; so if you’re unsure where yours is located, refer to your vehicle’s service manual for specific information about its placement.

What are the Symptoms of a Faulty Coolant Temperature Sensor?

A faulty coolant temperature sensor can cause a variety of issues for your car, and it’s important to be aware of the symptoms in order to know when it needs replacing. Common signs that you may have a faulty coolant temperature sensor include poor engine performance, increased exhaust emissions, an illuminated check engine light on the dashboard, as well as higher fuel consumption rates due to incorrect air/fuel mixtures. Additionally, your car may not warm up properly or take longer than usual for its heater to start working once turned on.

Finally, some cars with such sensors will run poorly at low speeds or idle speed until they are warmed up; after which they tend to run relatively normally again. If you experience any of these issues with your vehicle then it could indicate that you need to replace your coolant temperature sensor in order to get back optimal performance out of your car!

Will a Coolant Temperature Sensor Throw a Code?

When it comes to a coolant temperature sensor, the answer to whether or not it will throw a code depends on the type of error that is causing the issue. If the car’s computer detects an issue with its coolant temperature sensor and believes something isn’t functioning correctly, then yes, it can throw a code. The most common codes associated with this kind of problem are P0115 (Engine Coolant Temperature Circuit Malfunction) and P0117 ( Engine Coolant Temperature Circuit Low Input).

Both of these codes mean that there is either an electrical or mechanical fault in your vehicle’s cooling system. To diagnose what might be wrong, you’ll need to consult your owner’s manual as well as a professional mechanic who can run tests and check out any other possible problems related to your vehicle’s engine management system.

Does the Coolant Sensor Control the Thermostat?

The coolant sensor does not directly control the thermostat, but it plays an important role in helping to regulate engine temperature. The coolant sensor monitors the temperature of the engine and sends a signal to the car’s computer when it detects that the engine is getting too hot. The car’s computer then adjusts how much fuel is being used by opening or closing a valve that controls how much air enters into the combustion chamber.

This changes how quickly and efficiently fuel burns, which affects engine temperature. In addition, if there is a problem with your cooling system such as low levels of antifreeze or clogged radiators, then this can affect how well your vehicle regulates its own temperatures as well. Therefore, even though it doesn’t directly control your thermostat, your coolant sensor still plays an important role in maintaining proper engine temperatures for optimal performance and safety.

Dodge Caravan Coolant Temperature Sensor Location

The coolant temperature sensor on a Dodge Caravan is located in the engine block near the thermostat housing. It monitors the temperature of the engine’s coolant and sends signals to the vehicle’s computer system, which helps regulate engine performance. It should be replaced if it stops working properly or has been damaged due to corrosion or wear and tear.

The temperature sensor on a 2010 Dodge Caravan is located in the thermostat housing, which is typically mounted near the top of the engine. It’s important to note that not all models have a temperature sensor and some may require additional components to be installed before it can be used. If your Van does have one, you can easily access it by removing the air cleaner assembly and locating the two-wire connector connected to the thermostat housing.

Dodge Caravan Temperature Gauge Fluctuates

If you’re driving a Dodge Caravan and your temperature gauge is fluctuating, it could be an indication of a failing thermostat. The thermostat regulates the flow of coolant and when it starts to wear out, it can cause the temperature gauge to swing back and forth. If this happens in your vehicle, have a qualified mechanic inspect it as soon as possible so they can diagnose and repair any potential issues before they become more serious.


In conclusion, when looking for the coolant temperature sensor on a 2008 Dodge Grand Caravan, it is important to keep in mind that it is located near the radiator hose. It can be easily accessed with no need to remove other components. Knowing where this part is located can save time and money by avoiding having to take apart other parts of your vehicle.
