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 diagnosing a non-functioning radiator fan in your 2016 Ford Focus, it's crucial to follow a methodical diagnostic approach that starts with the simplest solutions before moving on to more complex issues. Begin by checking the fuse related to the radiator fan, as a blown fuse is a common and straightforward problem that can easily be fixed. If the fuse is in good condition, the next step is to inspect the relay, which controls the power supply to the fan; a faulty relay may need to be replaced to restore functionality. After that, test the fan motor by applying power directly to it; if the fan does not operate, it may indicate that the motor itself is defective and requires replacement. Additionally, assess the temperature sensor, which is responsible for signaling the fan to turn on when the engine reaches a certain temperature; a malfunctioning sensor can prevent the fan from activating. It's also essential to examine the wiring and connections for any signs of damage or loose connections that could interrupt power delivery. Lastly, using an OBD-II scanner to check for diagnostic trouble codes can help identify any specific issues within the cooling system. By following this structured approach, you can effectively diagnose and address the problem with your radiator fan, ensuring your vehicle operates efficiently.
When diagnosing the radiator fan issues in a 2016 Ford Focus, it's important to understand the common problems that could lead to its failure. A faulty fan motor is often the first thing to check, as it can prevent the fan from spinning and cause the engine to overheat. Additionally, a blown fuse in the fan circuit can cut off power to the fan, rendering it inoperative. It's also essential to inspect the fan blades for any damage; broken or bent blades can significantly reduce airflow, leading to cooling inefficiencies. Another factor to consider is the temperature sensor, which may malfunction and fail to trigger the fan when the engine reaches high temperatures. Lastly, wiring issues can disrupt the electrical connection, preventing the fan from receiving the necessary power to operate. By systematically checking these components, you can effectively troubleshoot and resolve the radiator fan issues, ensuring your vehicle runs smoothly and avoids overheating.
When it comes to the urgency of repairing a non-functioning radiator fan in a 2016 Ford Focus, the stakes are high. The radiator fan is essential for regulating the engine's temperature by ensuring that the radiator remains cool. If the fan fails, the engine is at risk of overheating, which can lead to severe consequences such as warped cylinder heads or blown head gaskets. These issues not only compromise the engine's integrity but can also result in costly repairs that far exceed the expense of a timely fan replacement. Additionally, an overheating engine can diminish fuel efficiency and overall vehicle performance, making it less reliable for daily use. Ignoring the problem can exacerbate damage to other cooling system components, such as the water pump or thermostat, leading to even higher repair costs. Therefore, it is crucial for DIY enthusiasts to recognize the importance of addressing a malfunctioning radiator fan promptly to maintain the vehicle's safety and functionality.
