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 first indication of a defective fan clutch is a healthy cooling system that runs below or above the normal temperature range. This is due to the fan running too fast or too slow. Also, a seized cooling fan will cause a loud roaring fan noise from under the hood every time the accelerator is pressed, and the engine will feel as if it lacks power. In this situation it would be very difficult to turn the engine cooling fan by hand, of course when the vehicle is off. Finally, if the clutch fails the fan will either turn very slowly, and not respond well to engine speed.
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.
When troubleshooting radiator fan issues in a Ford Explorer, it's essential to adopt a systematic diagnostic approach that begins with the simplest solutions before progressing to more complex assessments. Start by checking the coolant level, as low coolant can significantly impact the fan's performance. If the coolant level is adequate, inspect the fuse associated with the radiator fan; a blown fuse can easily disrupt functionality. Next, test the fan motor to ensure it operates correctly and is securely connected, as a malfunctioning motor can lead to overheating. If error codes are present, such as P0480, addressing these promptly is crucial to prevent further engine damage. Additionally, keep an eye out for any signs of leaks in the cooling system, as these can compromise efficiency. Finally, observe the fan activation patterns; understanding when the fans should engage can help pinpoint the issue. By following this structured approach, you can effectively diagnose and resolve radiator fan problems in your Ford Explorer, ensuring optimal engine performance and longevity.
When the radiator fan in your Ford Explorer isn't functioning, it's essential to methodically check several common problem areas to pinpoint the issue. Start by examining the radiator fan motor, as failures in the high-speed cooling fan relay terminals can lead to continuous operation or overheating, which may drain your battery. Next, inspect the fuse and relay, as a blown fuse or a faulty relay can disrupt the fan's operation entirely. Additionally, verify that the coolant level is sufficient; low coolant can hinder the fan's performance. It's also crucial to assess other cooling system components, including the coolant temperature sensor, motor, clutch, belt, wiring, and thermostat, as any faults here can contribute to fan malfunctions. Testing the electric radiator fans by connecting them to a car battery can help determine if the motors are operational. Lastly, ensure that the fan blades and motor are in good condition, as a failed motor will prevent the blades from spinning, leading to inadequate airflow and potential overheating. By systematically checking these components, you can effectively diagnose and resolve radiator fan issues, ensuring your Ford Explorer runs smoothly and efficiently.
When the radiator fan in your Ford Explorer is not functioning, it is crucial to address the issue without delay. Ignoring symptoms such as overheating or unusual engine behavior can lead to severe consequences, including engine damage or complete failure. Common culprits for a non-working radiator fan include a faulty fan assembly, a malfunctioning fan clutch, or a defective coolant temperature sensor. Start your troubleshooting by checking the coolant level and inspecting the fuse, as these are straightforward fixes that could resolve the problem. Additionally, be aware that error codes like P0480 indicate a cooling fan control circuit malfunction, which can exacerbate overheating issues. Remember, the radiator fan may not activate until the engine reaches a specific temperature, so understanding your vehicle's cooling system is essential. By addressing these issues promptly, you can avoid costly repairs and ensure your Ford Explorer operates safely and efficiently.
