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 the non-working radiator fan in your 2012 Dodge Charger, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the fan assembly for any visible damage, such as cracks or wear, which could hinder its operation. Next, test the fan clutch to ensure it is functioning correctly, as this component is vital for the fan's performance. Following this, examine the coolant temperature sensor, since a malfunction here can directly impact the fan's ability to operate. Don’t forget to check the fuse, as a blown fuse is a common culprit for electrical issues. After that, verify the integrity of the radiator fan relay control circuit, looking for any open or shorted circuits that could disrupt functionality. If you encounter fault codes, such as p0481, these can provide valuable insights into the cooling circuit's status. Additionally, consider swapping the fan relay with a known working one to rule out relay issues. Throughout this process, keep an eye out for any visible damage to the fan and monitor its operation as the engine reaches its operating temperature. If these steps do not resolve the issue, it may be time to consult a professional mechanic for further assistance. By following this diagnostic approach, you can efficiently identify and address the problem with your radiator fan.
When diagnosing radiator fan failure in a 2012 Dodge Charger, it's essential to consider several common problems that could be at play. One of the primary culprits is the fan assembly itself, which may become faulty over time, leading to inadequate cooling. Additionally, the fan clutch and coolant temperature sensor can also malfunction, preventing the fan from engaging when needed. Another factor to examine is the serpentine belt; if it has stretched or cracked, it may not effectively drive the fan, resulting in poor performance. Furthermore, the fan blades can suffer from wear or even separation, which not only impairs functionality but can also cause significant damage to the radiator and engine. By understanding these potential issues, DIYers can better troubleshoot and address radiator fan problems, ensuring their Charger remains in optimal working condition.
Fixing the radiator fan in a 2012 Dodge Charger is an urgent matter that should not be overlooked. A malfunctioning radiator fan can lead to significant overheating, which poses a serious risk to the engine's health. If the engine overheats, it can cause costly damage that may require extensive repairs or even engine replacement. Therefore, it is essential to diagnose and resolve any cooling fan problems as soon as they arise. Regular maintenance and prompt attention to warning signs, such as unusual engine temperatures or strange noises from the fan, can help prevent these issues from escalating. By prioritizing the repair of the radiator fan, you not only safeguard your vehicle's performance but also protect your investment from the potentially devastating consequences of neglect.
