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.
To effectively diagnose a non-functioning radiator fan in your 2015 Dodge Challenger, start with the simplest solutions before progressing to more complex diagnostics. Begin by checking the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue. If the fuse is intact, move on to the relay, specifically relay 18, to ensure it is functioning properly. If the relay checks out, inspect the fan resistor, as an open resistor could indicate a problem. Additionally, consider other potential causes such as low coolant levels, which can affect fan operation, or issues with the fan motor and wiring. To further test the fan, start the engine and allow it to reach normal operating temperature, then activate the A/C; this should trigger the fan if it is working correctly. Lastly, ensure that the Powertrain Control Module (PCM) is properly tuned to manage the fan parameters, as incorrect settings can prevent the fan from operating as intended. By following this structured approach, you can systematically identify and resolve the issue with your radiator fan.
When diagnosing why the radiator fan in a 2015 Dodge Challenger may not be functioning, it's essential to consider several common problems that could be at play. One of the primary culprits is the fan assembly itself, which can suffer from wear and tear or electrical issues that prevent it from operating correctly. Additionally, the fan clutch, responsible for engaging and disengaging the fan based on engine temperature, may malfunction, leading to inadequate cooling. Another critical component to inspect is the coolant temperature sensor; if this sensor fails, it may not signal the fan to activate, resulting in overheating. Addressing these issues promptly is crucial, as neglecting them can lead to severe engine damage. For DIY enthusiasts, understanding these potential failure modes can guide effective troubleshooting and repairs, ensuring the radiator fan operates efficiently and maintains optimal engine temperature.
When dealing with a non-functioning radiator fan in your 2015 Dodge Challenger, the urgency of repair cannot be overstated. The radiator fan is essential for regulating engine temperature; without it, your engine is at risk of overheating, which can lead to severe damage such as warped cylinder heads or blown head gaskets. These issues not only result in costly repairs but can also pose significant safety risks while driving. If you notice signs like a rising temperature gauge or steam from the engine bay, it’s crucial to act quickly. Ignoring these symptoms can escalate the problem, potentially leading to a seized engine and leaving you stranded. Therefore, addressing the malfunctioning radiator fan promptly is vital for maintaining your vehicle's performance and ensuring your safety on the road.
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.
