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 Escort, it's essential to adopt a methodical diagnostic approach. Begin by checking the fuse associated with the radiator fan; a blown fuse is often the simplest problem to resolve. If the fuse is intact, proceed to test the fan motor directly by connecting it to a power source to determine if it operates independently of the vehicle's electrical system. If the fan runs, the issue may lie elsewhere, such as in the fan relay or temperature sensor. Locating and inspecting the fan relay is crucial, as a malfunctioning relay can prevent the fan from receiving power. Additionally, testing the temperature sensor can help confirm whether it is functioning correctly; immersing it in boiling water can provide a quick check of its responsiveness. Lastly, inspect the wiring for any signs of damage or loose connections, as these can also disrupt the fan's operation. By following this structured approach, you can effectively diagnose and address radiator fan issues, ensuring your Ford Escort runs smoothly.
When the radiator fan in your Ford Escort fails to operate, it can lead to overheating and engine damage if not addressed promptly. Start by examining the fan assembly itself, as a malfunction here is a common culprit. If the fan appears intact, the next step is to check the fan clutch, which can sometimes fail to engage properly. Additionally, the coolant temperature sensor plays a crucial role in signaling the fan to turn on; a faulty sensor can disrupt this process. Don't overlook the blower motor relay, as issues with this component can also prevent the fan from functioning. The thermostatic switch, located on the thermostat housing, is another critical part that may need replacement if it fails to trigger the fan. If your radiator fan only activates when the air conditioning is on, inspect the Constant Control Relay or the Radiator Cooling Fan Motor relay, as these may be the source of the problem. Lastly, ensure that all relevant fuses are intact, as blown fuses can easily interrupt the fan's operation. By methodically checking these components, you can effectively diagnose and resolve the issue with your radiator fan, ensuring your Ford Escort runs smoothly and efficiently.
When the radiator fan in your Ford Escort is not functioning, it is crucial to address the problem 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 issues with the coolant temperature sensor. Additionally, electrical problems such as a blown fuse, a bad relay, or damaged wiring can also prevent the fan from operating. To ensure your vehicle remains in optimal condition, it is essential to diagnose the issue accurately. Start by checking the fuse and inspecting the fan for any visible damage. Ignoring these symptoms not only jeopardizes your vehicle's performance but also poses safety risks on the road. Taking immediate action can save you from more extensive repairs and keep your Ford Escort running smoothly.
