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.
When troubleshooting radiator fan issues in a Dodge Durango, it's essential to adopt a systematic diagnostic approach that begins with the simplest checks before progressing to more complex assessments. Start by verifying the coolant level, as low coolant can affect fan operation, and inspect the fuse related to the radiator fan to rule out any electrical issues. If these initial checks do not resolve the problem, consult the user manual for specific guidance tailored to your vehicle model. Next, consider swapping the fan and ASD relays in the Power Distribution Center (PDC) to see if a faulty relay is the culprit. Running the air conditioning can also provide insights, as the radiator fan should activate when the AC is on; if it doesn’t, further investigation into the refrigerant levels, switches, or wiring may be necessary. Additionally, ensure that the electrical connections are intact by testing the relay and checking for corrosion in the connectors. If power reaches the fan connector but the fan remains inactive, the issue may lie within the fan motor itself, which should be inspected for wear or damage. By following this structured approach, you can effectively diagnose and address radiator fan issues, ensuring your Dodge Durango operates smoothly.
When dealing with a non-working radiator fan in a Dodge Durango, it's essential to understand the common problems that could be at play. One of the primary culprits is the fan assembly itself, which may have failed due to wear or damage. Additionally, the fan clutch can malfunction, particularly in models that utilize an oil-filled clutch system, affecting the fan's ability to engage properly with the engine's speed. Another frequent issue arises from the coolant temperature sensor; if this sensor is faulty, it may not signal the fan to activate when needed, leading to overheating. Wiring problems, such as a blown fuse, a bad relay, or broken wires, can also disrupt the power supply to the fan, preventing it from operating. If power is reaching the fan connector but the fan remains inactive, this could indicate a failure within the fan motor itself or a problem with the connector. By systematically checking these components, DIYers can effectively troubleshoot and address the reasons behind a non-working radiator fan, ensuring their Dodge Durango runs smoothly and efficiently.
When the radiator fan in your Dodge Durango is not functioning, it is crucial to address the issue without delay. A malfunctioning radiator fan can lead to overheating, which poses serious risks to your engine's health and overall vehicle performance. Ignoring this problem may result in costly repairs or even engine failure, as excessive heat can damage vital components. Common culprits behind a non-working fan include a faulty fan assembly, a defective fan clutch, or a malfunctioning coolant temperature sensor. Additionally, electrical issues such as a blown fuse, a bad relay, or damaged wiring can also disrupt the fan's operation. To prevent further complications, it is advisable to conduct a thorough inspection of these components as soon as you notice any signs of fan failure. By taking prompt action, you can safeguard your vehicle's performance and avoid the potential for significant damage.
The first indication of a defective fan clutch is a healthy cooling system that runs below or above the normal temperature range. This is due to the fan running too fast or too slow. Also, a seized cooling fan will cause a loud roaring fan noise from under the hood every time the accelerator is pressed, and the engine will feel as if it lacks power. In this situation it would be very difficult to turn the engine cooling fan by hand, of course when the vehicle is off. Finally, if the clutch fails the fan will either turn very slowly, and not respond well to engine speed.
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.
