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 effectively diagnose the non-functioning radiator fan in your 2016 Ford Fiesta, begin with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Start by examining the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue that can halt fan operation. If the fuse is intact, proceed to inspect the relay, as a malfunctioning relay can also prevent the fan from activating. Next, test the fan motor directly by applying power to it; if it fails to operate, this may indicate that the motor needs replacement. Additionally, check the temperature sensor, which plays a crucial role in signaling the fan to turn on based on engine temperature. A faulty sensor can disrupt this process. Don’t forget to inspect all wiring and connections for any signs of damage or wear, as compromised wiring can lead to operational failures. Finally, using a diagnostic tool to scan for any Diagnostic Trouble Codes (DTCs) can provide further insights into specific issues affecting the fan system. By following this structured diagnostic approach, you can efficiently identify the root cause of the problem and determine the necessary repairs for your radiator fan.
When diagnosing why the radiator fan in a 2016 Ford Fiesta is not working, it's essential to consider several common problems that could be at play. One of the primary culprits is the fan assembly itself, which may have failed due to wear and tear or electrical issues. Additionally, the fan clutch can malfunction, preventing the fan from engaging when needed. Another critical component to inspect is the coolant temperature sensor; if it is faulty, it may not signal the fan to turn on, leading to overheating. Other potential issues include a blown fuse or a bad relay, which can interrupt the electrical flow to the fan. It's also wise to check for broken wires that could disrupt connectivity. Low coolant levels can cause the system to operate inefficiently, and physical damage to the fan blades can hinder performance. By systematically checking these components, DIYers can effectively identify and resolve the issue with the radiator fan in their Ford Fiesta.
Repairing a non-functioning radiator fan in your 2016 Ford Fiesta is an urgent matter that should not be overlooked. The radiator fan is essential for maintaining optimal engine temperature by effectively dissipating heat from the coolant. If the fan fails, the engine is at a heightened risk of overheating, which can lead to severe damage and costly repairs. Symptoms such as the engine temperature gauge rising or unusual noises from the engine compartment should prompt immediate action. Ignoring these signs can exacerbate the problem, especially in hot weather or during stop-and-go traffic, where the engine is more susceptible to overheating. Therefore, addressing the issue promptly not only safeguards your vehicle's performance but also ensures your safety on the road. Taking the time to repair or replace the radiator fan can save you from the significant consequences of engine failure down the line.
