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 Lincoln MKC, start with the simplest checks before moving on to more complex diagnostics. Begin by inspecting the fuse associated with the radiator fan; a burnt fuse is often the culprit and can be easily replaced with one of the same size and type. If the new fuse blows again, this indicates a potential electrical issue, such as an excessive draw from the fan motor. Next, examine the electric motor itself, as it is responsible for powering the fan blades. If the motor is malfunctioning, it may need replacement. Additionally, consider the role of the coolant temperature sensor, which signals the fan to activate when the engine reaches a certain temperature. If this sensor is faulty, it may not trigger the fan, leading to overheating. Lastly, check the thermostat, as a stuck open or closed thermostat can disrupt coolant flow, affecting the engine's temperature regulation and, consequently, the fan's operation. By systematically addressing these components, you can pinpoint the issue and restore your radiator fan's functionality.
When diagnosing why the radiator fan in a 2016 Lincoln MKC has stopped working, it's essential to consider several common problems that could be at play. One of the first things to check is the fuse; a blown fuse is often the simplest and most frequent cause of fan failure. If the fuse appears intact, the next step is to inspect the relay, as a faulty relay can disrupt the electrical flow necessary for the fan to operate. Additionally, examining the wiring for any breaks or damage is crucial, as a broken wire can prevent the fan from receiving power altogether. By systematically checking these components, DIYers can effectively identify and resolve the issue, ensuring the radiator fan functions properly and maintains optimal engine temperature.
Repairing a non-working radiator fan in a 2016 Lincoln MKC is an urgent matter that should not be overlooked. The radiator fan is essential for regulating the engine's temperature by dissipating heat generated during operation. When this component fails, the risk of engine overheating significantly increases, which can lead to severe and costly damage, such as warped cylinder heads or blown head gaskets. Ignoring the symptoms of a malfunctioning radiator fan can escalate the situation, potentially resulting in engine seizure, a problem that is not only expensive to fix but can also leave you stranded. Therefore, it is crucial to prioritize the repair of the radiator fan to ensure the engine operates within its optimal temperature range, safeguarding the vehicle's overall health and performance. Taking prompt action can prevent minor issues from evolving into major repairs, ultimately saving time and money in the long run.
