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.
When troubleshooting radiator fan issues in your Mercury Tracer, begin by examining the fan assembly to ensure it is operational. A simple visual inspection can reveal if the fan blades are intact and free from obstructions. Next, check the fan clutch to confirm it engages properly when the engine heats up; a malfunctioning clutch can prevent the fan from spinning at the necessary speed. Following this, verify the coolant temperature sensor, as it plays a crucial role in signaling the fan to activate. If the sensor is faulty, it may not trigger the fan when needed. Additionally, inspect the fan motor for functionality; a non-working motor will obviously hinder fan operation. Don’t forget to check the fan relay and fuse, as these components can easily fail and are often the simplest to replace. Lastly, if all else appears functional, take a look at the fan control module for any underlying issues. By following this methodical approach, you can effectively diagnose and resolve radiator fan problems, ensuring your Mercury Tracer runs smoothly.
When diagnosing a non-working radiator fan in a Mercury Tracer, it's essential to be aware of common problems that could be causing the malfunction. One frequent issue is a faulty fan motor, which may fail to operate due to electrical problems or wear and tear. Additionally, the fan relay or fuse could be blown, preventing power from reaching the fan. Another common culprit is the coolant temperature sensor, which may not signal the fan to turn on when the engine reaches a certain temperature. If the fan clutch is defective, it may not engage properly, leading to inadequate cooling. Lastly, obstructions in the fan assembly, such as debris or damaged blades, can hinder the fan's ability to spin freely. By understanding these potential failure modes, you can systematically check each component and effectively troubleshoot the issue with your radiator fan.
When the radiator fan in your Mercury Tracer fails to operate, it’s crucial to address the issue promptly to avoid severe engine damage. A malfunctioning fan can lead to overheating, which may cause the engine to seize or result in costly repairs. Common culprits include a faulty fan assembly, a defective fan clutch, or a malfunctioning coolant temperature sensor. Additionally, worn serpentine belts can hinder the fan's performance, exacerbating the problem. If you notice that the fan does not engage when the engine is hot or when the A/C is activated, it’s a clear sign that immediate attention is needed. Ignoring these symptoms can not only compromise your vehicle's performance but also pose safety risks on the road. Therefore, it’s essential to troubleshoot the issue by checking the fan assembly, relays, and fuses, ensuring that your Mercury Tracer remains in optimal working condition.
