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 a non-functioning radiator fan in a 2020 Dodge Durango, it's essential to adopt a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by inspecting the fuse associated with the radiator fan, as a blown fuse is a common and easily rectifiable issue. If the fuse is intact, proceed to examine the relay that controls the fan; a malfunctioning relay can disrupt the fan's operation. Next, test the fan motor directly by applying power to it; if it fails to activate, the motor may need replacement. Additionally, check the temperature sensor, which is vital for triggering the fan when the engine reaches a certain temperature. Ensure that the wiring and connections are secure and free from damage, as loose or frayed wires can hinder performance. Finally, utilizing a diagnostic scanner to check for error codes can provide further insights into any underlying issues within the cooling system. By following this structured diagnostic approach, you can efficiently identify and address the cause of the radiator fan's malfunction.
When facing issues with the radiator fan in a 2020 Dodge Durango, it's essential to understand the common problems that could be at play. One of the primary culprits is a faulty fan motor, which may require replacement to restore functionality. Additionally, a blown fuse in the fan circuit can disrupt power, so checking and replacing any blown fuses is a crucial step in the troubleshooting process. Another potential issue is a faulty relay, which can prevent the fan from receiving the necessary power; replacing this component can often resolve the malfunction. Furthermore, a malfunctioning coolant temperature sensor may fail to signal the fan to activate, necessitating its replacement to ensure proper operation. Lastly, wiring issues, such as damaged or loose connections, can also hinder the fan's performance, making it important to inspect and repair any problematic wiring. By systematically addressing these common causes, DIYers can effectively troubleshoot and fix the radiator fan issue in their Dodge Durango.
Addressing a non-functioning radiator fan in your 2020 Dodge Durango is not just a matter of convenience; it is a critical safety concern that demands immediate attention. The radiator fan plays a vital role in regulating engine temperature by dissipating heat from the radiator. When this component fails, the risk of engine overheating escalates significantly, which can lead to severe damage such as warped engine parts or even complete engine failure. Ignoring this issue can result in costly repairs and may leave you stranded on the road, requiring towing assistance. Therefore, if you notice any signs of a malfunctioning radiator fan, such as unusual engine temperatures or strange noises, it is essential to diagnose and repair the problem promptly to ensure the longevity and reliability of your vehicle. Taking swift action not only protects your investment but also enhances your safety on the road.
