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 Ford Focus, it's essential to adopt a systematic diagnostic approach. Begin by checking the fuse associated with the radiator fan; a blown fuse is a straightforward fix that can often resolve the issue. If the fuse is intact, proceed to test the power supply to the fan motor, as a lack of power could indicate wiring problems or a faulty relay. Next, consider the functionality of the air conditioning system, as the fan should activate when the AC is turned on in many models. If the fan remains unresponsive, inspect the cooling fan components, particularly the plug-in connector and the resistor pack, which are known to fail in the Zetec engine. Lastly, evaluate the thermostat's performance; if it fails to open at the correct temperature, it may prevent the fan from operating when needed. By following this structured approach, you can effectively diagnose and address radiator fan issues, ensuring your Ford Focus runs smoothly.
When tackling the issue of a non-working radiator fan in your Ford Focus, it's essential to understand the common problems that can arise. One frequent culprit is a blown fuse, which can easily be checked and replaced if necessary. If the fuse continues to blow, it may indicate a deeper electrical issue, such as a short circuit or excessive draw from the fan. Additionally, the physical condition of the fan itself should be inspected for any visible damage or wear that could hinder its operation. Testing the fan by adjusting the climate control settings can also reveal whether the fan motor is functioning correctly. Blockages in the fan blades can prevent proper airflow, so ensure that the blades can spin freely without obstruction. If these steps do not resolve the issue, consulting the owner's manual for specific fuse locations or considering a fan motor replacement may be necessary. By being aware of these common problems, you can effectively diagnose and address the issues with your radiator fan, ensuring your Ford Focus runs smoothly.
When the radiator fan in your Ford Focus is not working, it is 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, electrical issues such as a blown fuse, a bad relay, or damaged wiring can disrupt the fan's operation. The fan module is often a key player in these problems, as it can fail and prevent the fan from receiving the necessary signals to operate. Overheating can also affect the cooling fan plug-in connector, leading to further complications. If you notice your radiator fan is not functioning, it is essential to diagnose the issue quickly to ensure your vehicle remains safe and reliable on the road.
