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 a non-functioning radiator fan in your 2016 Ford Taurus, begin with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Start by inspecting 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 examine the relay, which is crucial for supplying power to the fan. A malfunctioning relay can prevent the fan from activating, so ensure it is working correctly. Next, test the fan motor directly by applying power to it; if it fails to operate, it may need replacement. Additionally, check the temperature sensor, as it plays a vital role in signaling the fan to turn on when the engine reaches a specific temperature. If the sensor is faulty, it can disrupt the fan's operation. Don’t forget to inspect the wiring for any signs of damage or loose connections, as these can impede electrical flow. Finally, using an OBD-II scanner to check for diagnostic trouble codes can provide insights into any underlying issues with the cooling system. By following this structured diagnostic approach, you can efficiently identify and resolve the problem with your radiator fan.
When diagnosing why the radiator fan in a 2016 Ford Taurus is not functioning, it's essential to consider several common problems that could be at play. A faulty fan motor is often the primary suspect, as it directly impacts the fan's ability to cool the radiator. Additionally, a blown fuse can disrupt the electrical flow necessary for the fan to operate, making it a straightforward issue to check. Another critical component is the temperature sensor; if it fails, it may not signal the fan to activate when the engine reaches high temperatures. Wiring issues, such as damaged or corroded connections, can also prevent the fan from receiving power, leading to operational failure. Lastly, ensure that the coolant level is adequate, as low coolant can hinder the fan's performance and contribute to engine overheating. By systematically evaluating these potential causes, you can effectively troubleshoot the radiator fan issue in your Ford Taurus.
Repairing a non-functioning radiator fan in a 2016 Ford Taurus is an urgent matter that should not be overlooked. The radiator fan is essential for regulating the engine's temperature by ensuring that the radiator receives adequate airflow for cooling. When this fan fails, the risk of engine overheating significantly increases, which can lead to severe damage to vital engine components such as the cylinder head gasket and pistons. Ignoring this issue can result in costly repairs, including warped cylinder heads or even a cracked engine block, which are not only expensive but can also render your vehicle inoperable. Therefore, addressing the malfunction of the radiator fan promptly is crucial to maintaining the health of your engine and avoiding the potential for catastrophic failure. Taking immediate action can save you from extensive repair costs and ensure the longevity of your vehicle.
