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.
When diagnosing a non-functioning radiator fan in your 2012 Ford Explorer, it's essential to adopt a systematic diagnostic approach that prioritizes simpler checks before moving on to more complex issues. Start by inspecting the fuse associated with the radiator fan; a blown fuse is a common and easily fixable problem. If the fuse is intact, examine the fan assembly for any visible damage or obstructions that could prevent it from operating. Next, assess the fan clutch, as its malfunction can significantly impact the fan's performance. Finally, test the coolant temperature sensor, which regulates the fan's operation based on engine temperature. By following this methodical process, you can effectively identify the root cause of the issue and implement the necessary repairs, ensuring your radiator fan operates efficiently.
When troubleshooting the radiator fan issue in a 2012 Ford Explorer, 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 cut off power to the fan, rendering it inoperative. It's also important to check the relay, which is responsible for supplying power to the fan motor; if this component fails, the fan will not function. The coolant temperature sensor is another critical element, as it regulates the fan's operation based on engine temperature; a malfunction here can prevent the fan from activating when needed. Wiring issues, such as damaged or corroded connections, can disrupt the electrical flow to the fan, while a defective cooling fan module may also inhibit the fan's performance. By systematically examining these potential causes, you can effectively diagnose and resolve the radiator fan problem, ensuring your vehicle maintains optimal engine cooling.
When it comes to maintaining your 2012 Ford Explorer, addressing a non-working radiator fan should be a top priority. The radiator fan is essential for regulating engine temperature, especially during stop-and-go traffic or in high temperatures. If the fan fails, the engine can quickly overheat, leading to severe damage that may require costly repairs or even a complete engine replacement. Ignoring this issue not only risks the integrity of the engine but can also affect other components, such as the temperature sensor and wiring harness, compounding the problem and expenses. For DIY enthusiasts, understanding the critical role of the radiator fan in the cooling system underscores the importance of prompt action. By diagnosing and repairing the fan as soon as possible, you can safeguard your vehicle's performance and longevity, ensuring a smoother and safer driving experience.
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.
