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-working radiator fan in a 2011 Dodge Challenger, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by examining the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue that can halt fan operation. Next, inspect the relay that controls the fan, as a malfunctioning relay can prevent the fan from receiving power. If these components are functioning correctly, proceed to test the radiator fan motor itself to ensure it operates as intended; if it doesn’t, replacement may be necessary. Additionally, check the wiring for any signs of damage or loose connections, as these can disrupt power flow to the fan. It’s also crucial to verify the coolant temperature sensor, since a faulty sensor may fail to signal the fan to activate when needed. Finally, using 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 resolve the problem with the radiator fan.
When troubleshooting a non-working radiator fan in a 2011 Dodge Challenger, it's crucial to consider several common problems that could be at play. One of the primary culprits is a faulty fan motor, which can fail to operate and lead to engine overheating. Additionally, a blown fuse in the fan circuit can interrupt the power supply, preventing the fan from functioning altogether. Another potential issue is a defective relay, which is responsible for controlling the fan's operation; if this component fails, the fan may not activate when needed. Furthermore, broken or damaged wiring can disrupt the electrical flow to the fan, causing it to malfunction. Lastly, a malfunctioning coolant temperature sensor may fail to signal the fan to turn on at the correct temperature, exacerbating overheating issues. By systematically checking these components, DIYers can effectively diagnose and resolve the radiator fan problem, ensuring the vehicle runs smoothly and efficiently.
Repairing a non-functioning radiator fan in your 2011 Dodge Challenger is an urgent matter that should not be overlooked. A malfunctioning fan can lead to severe engine overheating, which poses a significant risk of damaging critical engine components. If you notice visible signs of damage, such as broken fan blades or corrosion, it is essential to act quickly, as these are clear indicators that the fan requires immediate attention. Common issues like a blown fuse or a faulty fan motor can often be diagnosed and repaired with some basic DIY skills, but delaying this repair can lead to more extensive and costly damage. While your air conditioning may still function without the radiator fan, it can exacerbate overheating, particularly during low-speed driving or idling. Therefore, to maintain the health of your engine and avoid potential breakdowns, it is crucial to address any radiator fan issues as soon as they arise.
