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.
To effectively diagnose a non-functioning radiator fan in your 2013 Dodge Avenger, start with the basics by ensuring the engine is at its operating temperature, as the fan should activate when the coolant reaches around 228°F. Next, check for power and ground at the fan motor using a multimeter; if power is present but there's no ground, the issue may lie with the temperature sensor or wiring. Conversely, if there's no power, investigate the relay, fuse, or wiring. Disconnecting the coolant temperature sensor can help determine if it's faulty; if the fan activates, the sensor is likely the culprit. Additionally, inspect the relays and fuses in the power distribution center, swapping relays to test functionality. Examine the wiring for any damage or corrosion, ensuring all connections are secure. If the thermostat is stuck open or missing, it may prevent the engine from reaching the necessary temperature for fan activation. If the fan remains unresponsive even when directly powered from the battery, the fan motor itself may be defective. Utilizing a scan tool can provide further insights into the system's status and any trouble codes. By following this structured approach, you can systematically identify the root cause of the radiator fan issue.
When troubleshooting the radiator fan issues in a 2013 Dodge Avenger, it's essential to consider several common problems that could be at play. A blown or faulty fuse is often the first culprit, as it can disrupt the electrical flow necessary for the fan to operate. If the fuse is intact, the next step is to examine the cooling fan motor itself; ensuring that it receives both power and ground can help determine if the motor is defective. Additionally, relay issues can arise, particularly with the Total Integrated Power Module (TIPM), which controls the fan's operation. Testing the relays for damage or corrosion can reveal potential faults. Another critical component to check is the coolant temperature sensor, as a malfunction here can prevent the fan from activating when needed. Furthermore, the thermostat's functionality is vital; if it is stuck open or missing, the engine may not reach the optimal temperature, affecting fan operation. Lastly, inspect the wiring and connections for any signs of damage or looseness, as these can also hinder the fan's performance. By systematically addressing these areas, you can effectively diagnose and resolve the radiator fan issues in your vehicle.
When dealing with a non-functioning radiator fan in a 2013 Dodge Avenger, the urgency of repair cannot be overstated. A malfunctioning fan significantly increases the risk of engine overheating, especially during low-speed driving or when the vehicle is stationary, where airflow is minimal. This overheating can lead to catastrophic engine damage, including issues like head gasket failure or even a cracked engine block, which can result in costly repairs. Additionally, if there is a coolant leak, the situation worsens, as low coolant levels can cause the temperature sensor to malfunction, further exacerbating the overheating risk. It is crucial to act swiftly; running the engine without a functioning radiator fan can lead to permanent damage to vital components such as the thermostat and head gaskets. Therefore, immediate diagnostic and repair steps are essential to prevent severe engine damage and ensure the longevity of your vehicle. Addressing this issue promptly not only safeguards your engine but also enhances your overall driving safety.
