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 faced with a non-functioning radiator fan in a 2010 Ford Explorer Sport Trac, it's crucial to adopt a systematic diagnostic approach. Begin by checking the fuse associated with the radiator fan, as a blown fuse is a common and easily fixable issue that can halt fan operation. If the fuse is intact, the next step is to inspect the relay, which controls the power supply to the fan; testing or replacing a faulty relay can restore functionality. Following this, assess the fan motor itself by applying direct power to it; if the motor fails to operate, it may need replacement. Additionally, verify the temperature sensor's performance, as it plays a vital role in signaling the fan to activate when the engine reaches a specific temperature. Lastly, examine the wiring and connections for any signs of damage or corrosion, as compromised wiring can disrupt power flow to the fan. By methodically working through these steps, you can effectively diagnose and address the radiator fan issue, ensuring your vehicle operates smoothly.
When diagnosing why the radiator fan in a 2010 Ford Explorer Sport Trac has stopped working, it's essential to consider several common problems that could be at play. One of the primary culprits could be a faulty fan assembly or fan clutch, which may prevent the fan from operating effectively. Additionally, the coolant temperature sensor plays a crucial role in signaling when the fan should engage; if this sensor is malfunctioning, it may not trigger the fan at the appropriate times. Electrical issues are also a frequent cause of fan failure; a blown fuse, a defective relay, or damaged wiring can disrupt the power supply to the fan. Furthermore, the condition of the serpentine belts should not be overlooked, as any signs of wear, such as stretching or cracking, can impact the fan's performance. It's also important to remember that the radiator fan may not activate until the engine reaches a specific temperature, so patience is sometimes required during troubleshooting. By systematically checking these components, DIYers can effectively identify and resolve the issue with the radiator fan.
Repairing the non-working radiator fan in your 2010 Ford Explorer Sport Trac 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 this component fails, the risk of engine overheating significantly increases, which can lead to severe consequences such as warped cylinder heads, blown head gaskets, and even complete engine failure. These issues not only compromise the vehicle's performance but can also result in costly repairs that could have been avoided with prompt action. Therefore, addressing the malfunctioning radiator fan as soon as possible is crucial for maintaining the health and longevity of your vehicle, ensuring it operates within the optimal temperature range and preventing any long-term damage. Ignoring this issue can lead to safety risks and substantial financial burdens, making it imperative to prioritize the repair of your radiator fan.
