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 your Ford Fusion, it's essential to adopt a systematic diagnostic approach. Begin by locating the radiator fan relays, as these are often the first components to check. Carefully remove each relay to identify any that may be faulty. Next, inspect common causes such as sensor failures or motor problems, as these can significantly impact fan operation. Pay close attention to specific components like the fan motor, clutch, and fuses, as pinpointing the exact source of the issue is crucial for effective resolution. Don't forget to check the fuses located behind the glove box, as a blown fuse can prevent the fan from functioning. Additionally, examine the cooling fan module by locating Relay #29 in the fuse block under the hood; pulling this relay can help determine if the fan shuts off, indicating a potential relay issue. If the fan continues to malfunction, consider replacing the cooling fan module situated on the fan shroud. By following this structured approach, you can efficiently diagnose and resolve radiator fan issues, ensuring your Ford Fusion operates smoothly.
When diagnosing and fixing a non-working radiator fan in a Ford Fusion, it's crucial to be aware of the common problems that may arise. A blown fuse is often the first issue to check, as it can easily disrupt the fan's operation. If the fuse is intact, inspect the fan for any obstructions such as dirt or debris that could hinder its movement; cleaning these blockages can often restore functionality. Additionally, consider the possibility of faulty relays, low coolant levels, or issues with the fan motor and wiring, as these can also lead to fan failure. Understanding these common failure modes will empower you to troubleshoot effectively and address the root cause of the problem, helping to prevent engine overheating and ensuring your Ford Fusion operates smoothly. If you find that the fan still does not work after these checks, seeking assistance from a professional mechanic may be necessary to avoid further complications.
When the radiator fan in your Ford Fusion is not functioning, it is crucial to address the issue promptly to avoid severe engine damage or overheating. A malfunctioning fan can lead to increased engine temperatures, which may cause the engine to overheat, resulting in costly repairs or even complete engine failure. Additionally, if the fan is not operating, it can affect the performance of the air conditioning system, leading to discomfort during hot weather. Before diving into repairs, start by checking the fuse associated with the radiator fan, as a blown fuse is a common and easily fixable issue. If the fuse is intact, inspect the fan assembly and the coolant temperature sensor, as these components are often the culprits behind fan failure. Furthermore, ensure there are no obstructions in the radiator that could impede airflow. Remember, while DIY troubleshooting is valuable, if the problem persists, seeking professional assistance is advisable to prevent further damage and ensure your vehicle's safety.
