The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
Over time serpentine belts stretch, crack, and the ribs that ride on the accessory pulleys being to wear smooth. A squealing noise that increases with engine speed or as engine driven accessories are turned on may be noted. The noise is caused by the belt slipping on the pulleys, insufficiently driving them. Ineffective air conditioning, a battery warning light, or intermittent power steering assist can result from this.
The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed.
A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air.
A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues.

When the engine coolant temperature sensor fails, it will send inaccurate information to the vehicle’s computer, causing the computer to react to false operating conditions. This will cause the engine to consume more fuel than normal, depleting fuel mileage, and causing black, sooty smoke from the engine under moderate to heavy acceleration. The check engine light will illuminate, and on-board diagnostic trouble codes may be stored for exhaust and emission system failure, fuel delivery system failure, and engine cooling system failure. Overheating may also occur, as the coolant sensor may be leaking fluid out of the engine, creating a an air pocket in the system.
When the radiator fans stop functioning properly, the engine temperature will rise. The spike in temperature will be highest when the vehicle is idling at a stop, but should subside once the vehicle begins moving again.
Additionally, the air conditioner typically won't blow as cold. This is because the air from the radiator fans also blows across the air conditioning condenser, so when the fans fail, both systems suffer.
You'll also usually see the check engine light and notice a drop in fuel economy. It's possible the fan will start making noise if it's failing, as well.
To effectively diagnose the non-functioning radiator fan in your 2013 Dodge Durango, start with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by inspecting the signal wire for any shorts, as this can often be a straightforward issue that prevents the fan from operating. Next, examine the fan assembly, fan clutch, and coolant temperature sensor, as these components are commonly responsible for fan malfunctions. Testing the coolant temperature sensor is crucial since it sends the necessary signal to the ECU to activate the fan; a faulty sensor can disrupt this process. Additionally, check the fan relay, which serves as a switch for the fan's power supply; using a multimeter can help determine if the relay is functioning correctly. Don’t forget to inspect the fan motor for any signs of wear, such as a stiff fan blade or worn bearings, which could indicate the need for replacement. Finally, verify that power is reaching the fan connector when the AC is activated, as this can help pinpoint whether the issue lies with the fan itself or the electrical connections. By following this structured diagnostic approach, you can efficiently identify the root cause of the radiator fan's failure and take the necessary steps to resolve the issue.
When diagnosing why the radiator fan in a 2013 Dodge Durango is not working, it's essential to consider several common problems that could be at play. One of the primary culprits could be a faulty fan assembly or fan clutch, which may prevent the fan from engaging when needed. Additionally, the coolant temperature sensor plays a crucial role in signaling the fan to operate; if this sensor is malfunctioning, it may not trigger the fan at the appropriate times. Another area to investigate is the wiring; a short in the signal wire can sometimes be resolved by wiggling it, indicating a potential connection issue. Furthermore, the fan motor itself, along with the fan relay and fuse, should be checked, as these components are vital for the fan's operation. If the fan appears to be functioning but still isn't cooling effectively, consider the possibility of a faulty thermostat or air trapped in the coolant system, both of which can disrupt the cooling process. By systematically examining these components, DIYers can effectively troubleshoot and resolve the issue with the radiator fan.
Fixing the radiator fan in a 2013 Dodge Durango is an urgent matter that should not be overlooked. The radiator fan plays a crucial role in regulating engine temperature, and any malfunction can lead to severe consequences, including engine overheating. This overheating can result in extensive damage, potentially leading to costly repairs or even engine failure. If you notice any signs of a malfunctioning radiator fan, such as unusual noises, erratic temperature readings, or the fan not engaging when the engine is hot, it is imperative to address these issues immediately. Delaying repairs not only jeopardizes the vehicle's performance but also poses safety risks on the road. Therefore, prioritizing the repair of the radiator fan is essential for maintaining the overall health of your Dodge Durango and ensuring a safe driving experience.
