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 diagnose the non-functioning radiator fan in your 2013 Dodge Dart, start by checking the fuses associated with the fan system, specifically Fuse 2 and Fuse 9, to ensure they are intact and receiving power. If the fuses are operational, proceed to test the fan relay located in the under-hood fuse/relay box; swapping it with a similar relay can help determine if it’s the source of the problem. Next, examine the engine coolant temperature sensor by disconnecting it to see if the fan activates; if it does, the sensor or its wiring may be faulty. To further isolate the issue, perform a direct power test on the fan motor by connecting it directly to a power source; if it fails to operate, the motor likely needs replacement. Additionally, verify that the fan module has proper power and ground feeds, as any faults here can disrupt functionality. Finally, utilize an OBD-II scanner to check for diagnostic trouble codes that may provide insight into the fan control circuit. By following this structured approach, you can effectively identify the cause of the radiator fan malfunction and take appropriate action.
When troubleshooting the radiator fan issues in a 2013 Dodge Dart, it's essential to consider several common problems that could be at play. Start by examining the fuses associated with the cooling fan circuit, particularly fuse 2 and fuse 9, as blown fuses can disrupt power to the fan. If the fuses are intact, the next step is to check the fan relay, which may be faulty; swapping it with a similar relay can help determine if this is the issue. Additionally, inspect the wiring and connectors for any signs of damage or corrosion, as these can impede electrical flow. The Radiator Fan Module is another critical component; if it malfunctions, it may fail to send the necessary signals to the fan. The engine coolant temperature sensor also plays a vital role in fan operation, so testing it by disconnecting it can reveal whether it’s functioning correctly. Lastly, consider the fan motor itself, as a direct power test can confirm if it needs replacement. By systematically addressing these potential issues, you can effectively diagnose and resolve the radiator fan problem in your vehicle.
When it comes to the urgency of repairing a non-functioning radiator fan in a 2013 Dodge Dart, the stakes are high. The radiator fan plays a crucial role in regulating engine temperature, and its failure can lead to rapid overheating, particularly in stop-and-go traffic or when idling. Ignoring this issue can result in severe consequences, including a seized engine, which is not only a major inconvenience but also an expensive repair. Additionally, a damaged head gasket can lead to coolant leaks and further engine complications, while a warped cylinder head or engine block can incur significant costs. Therefore, it is imperative to act swiftly. Start by checking the fuses and relays associated with the cooling system, as these are often the culprits behind fan failure. If those components are functioning, test the fan motor directly to see if it operates when powered independently. Inspecting the wiring and connectors for any signs of damage or corrosion is also essential, as these can prevent the fan from receiving the necessary power. If immediate repairs are not feasible, consider temporary solutions like bypassing the fan relay to keep the fan running until a proper fix can be made. In summary, addressing the malfunctioning radiator fan without delay is vital to safeguard your engine from overheating and the costly repairs that can follow.
