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 Lincoln MKZ, it’s essential to adopt a systematic diagnostic approach that begins with the simplest checks. Start by examining the fuse associated with the radiator fan, as a blown fuse is a common issue that can easily be resolved. If the fuse is intact, the next step is to inspect the relay that controls the fan; a faulty relay can prevent the fan from operating. Following this, test the radiator fan motor itself to ensure it is functioning properly; if it does not run, it may need to be replaced. Additionally, check the wiring connected to the fan for any signs of damage or loose connections, as these can disrupt the power supply. Utilizing a diagnostic scanner can also be beneficial, as it can reveal any error codes related to the fan system, helping to pinpoint the issue more accurately. Finally, verify the operation of the coolant temperature sensor, since a malfunctioning sensor may fail to activate the fan when necessary. By following this structured approach, you can efficiently identify and address the problem with your radiator fan, ensuring your vehicle operates smoothly.
When troubleshooting the radiator fan issue in a 2016 Lincoln MKZ, it's essential to consider several common problems that could be at play. A faulty fan motor is often the primary culprit, as a malfunctioning motor will prevent the fan from spinning and effectively cooling the radiator. Additionally, a blown fuse can disrupt the electrical flow to the fan, so checking the fuse box for any damaged fuses is a crucial step. Another potential issue is a faulty relay, which controls the power supply to the fan; if this relay fails, the fan won't operate. The coolant temperature sensor also plays a vital role, as it regulates the fan's operation based on engine temperature; if this sensor is malfunctioning, the fan may not turn on when needed. Wiring issues, such as damaged or corroded connections, can further complicate matters by interrupting the electrical current to the fan. Lastly, ensure that the coolant levels are adequate, as low coolant can affect the fan's performance. By systematically addressing these common causes, you can effectively diagnose and potentially resolve the radiator fan issue in your Lincoln MKZ.
Repairing a non-functioning radiator fan in a 2016 Lincoln MKZ 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 remains cool. When the fan fails, the engine is at risk of overheating, which can lead to severe damage such as warped cylinder heads or blown head gaskets. These issues not only compromise the vehicle's performance but can also result in costly repairs or even a complete engine replacement if the problem is not addressed promptly. To avoid the risk of overheating and the associated dangers, it is advisable to refrain from driving the vehicle until the radiator fan is repaired. Taking immediate action can save you from significant financial burdens and ensure the longevity of your engine.
