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.
When troubleshooting radiator fan issues in a Dodge Dart, it's essential to adopt a systematic diagnostic approach that begins with the simplest solutions before progressing to more complex assessments. Start by checking the fuse associated with the radiator fan; a blown fuse is often a straightforward fix that can restore functionality. If the fuse is intact, it's crucial to monitor the fan's operation, particularly when the engine reaches its normal operating temperature or when the air conditioning is activated. This observation can help determine if the fan is responding appropriately. If the fan fails to engage, inspect the electrical system for any faults, as issues in the wiring or control signals can prevent the fan from operating. Additionally, testing the radiator cooling fan directly can reveal whether the fan motor itself is malfunctioning. If these initial checks do not resolve the issue, consider examining the fan motor and control module for any signs of failure. By following this structured approach, you can effectively diagnose and address radiator fan problems, ensuring your Dodge Dart maintains optimal cooling performance.
When troubleshooting a non-working radiator fan in your Dodge Dart, it's crucial to recognize the common problems that may be causing the issue. Start by checking the coolant level, as low coolant can lead to overheating, which in turn may prevent the fan from functioning properly. If the coolant level is adequate, the next step is to inspect the fuse related to the radiator fan; a blown fuse can cut off power and stop the fan from operating. If these initial checks do not resolve the issue, testing the fan assembly becomes essential. The fan itself, along with components like the fan clutch or coolant temperature sensor, could be malfunctioning and preventing the fan from engaging. Additionally, keep an eye out for faulty sensors, as they can also disrupt the fan's operation. Addressing any identified problems promptly is key to restoring the fan's functionality. Lastly, be prepared for potential repair costs, as diagnosing and fixing these issues may require professional help. By understanding these common failure modes, you can effectively navigate the troubleshooting process and enhance your chances of a successful repair.
When the radiator fan in your Dodge Dart fails to operate, it’s crucial to address the issue promptly to avoid potential overheating and engine damage. Common culprits include a malfunctioning fan assembly, fan clutch, or coolant temperature sensor, which can disrupt the cooling system's efficiency. Additionally, using aftermarket sensors instead of genuine Mopar parts may lead to compatibility issues, further complicating the problem. If the fan does not activate when the AC or defrost settings are engaged, it could indicate wiring issues or a faulty connector that needs immediate attention. Moreover, a blown fuse can also prevent the fan from functioning, so checking the fuses is a simple yet essential step in troubleshooting. Ignoring these symptoms can lead to severe engine complications, making it imperative to diagnose and resolve the issue as soon as possible to ensure the longevity and safety of your vehicle.
