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.
When troubleshooting radiator fan issues in your Dodge Avenger, it's essential to adopt a methodical diagnostic approach. Begin by checking the coolant level, as low coolant can hinder the fan's operation. Next, inspect the fuse associated with the radiator fan; a blown fuse is a straightforward fix that can often resolve the issue. If the fan remains unresponsive, try running the air conditioning, which should activate the fan if it's functioning correctly. If the fan still does not operate, test the fan motor for faults, as a malfunctioning motor is a common culprit. Additionally, examine the fan relay, as a defective relay can prevent the fan from turning on. Don't overlook the temperature sensor, which is vital for fan operation; issues here can lead to malfunctions. Lastly, inspect the wiring for any damage or loose connections that could disrupt the fan's functionality. If all these checks do not yield results, consulting the Powertrain Control Module (PCM) may provide further insights into the fan's behavior. By following this structured approach, you can effectively diagnose and potentially resolve radiator fan issues in your Dodge Avenger.
When diagnosing a non-working radiator fan in a Dodge Avenger, it's crucial to be aware of the common problems that can lead to fan failure. Begin by inspecting the fan assembly for any visible damage or wear, as these physical issues can significantly affect functionality. If your vehicle features a fan clutch, ensure it is operating correctly, since a malfunctioning clutch can prevent the fan from performing efficiently. The coolant temperature sensor is another vital component; if it fails, it may not signal the fan to activate when necessary, leading to overheating. Additionally, check the radiator fan motor to confirm it is receiving power and functioning properly. A faulty relay can also disrupt the fan's operation, so look for any signs of damage there. Secure wiring connections are essential, as loose or damaged wires can impede the fan's performance. Testing the fuse associated with the radiator fan is also important, as a blown fuse can completely cut off power to the fan. Lastly, consider the cooling fan control module, which can be another source of failure. By systematically evaluating these common issues, you can effectively diagnose and resolve the problem with your radiator fan, ensuring your Dodge Avenger runs smoothly.
When the radiator fan in your Dodge Avenger fails to operate, it is crucial to address the issue promptly to avoid severe consequences. A malfunctioning radiator fan can lead to overheating, which may cause extensive engine damage and costly repairs. Additionally, if the fan is not functioning due to a blown fuse, bad relay, or faulty coolant temperature sensor, the engine may struggle to maintain optimal operating temperatures, affecting performance and fuel efficiency. Ignoring these symptoms can escalate into more significant problems, such as a complete engine failure or compromised safety while driving. Therefore, it is essential to diagnose the root cause of the fan's malfunction—whether it be a simple fuse replacement or a more complex issue involving the Powertrain Control Module (PCM)—to ensure your vehicle remains safe and reliable on the road. Taking immediate action not only protects your investment but also enhances your driving experience by maintaining the vehicle's performance.
