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.
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.
To effectively diagnose a non-working radiator fan in your 1996 Toyota Corolla, begin with a systematic approach that prioritizes simpler checks before delving into more complex issues. Start by inspecting the fuse associated with the radiator fan; a blown fuse is a common and easily fixable problem that can halt fan operation. If the fuse is intact, proceed to examine the relay, which is crucial for powering the fan. Testing or replacing a faulty relay can often resolve the issue. Next, test the fan motor directly by applying power to it; if it fails to operate, the motor may need replacement. Additionally, check the temperature sensor, as it plays a vital role in activating the fan when the engine reaches a specific temperature. If the sensor is functioning correctly, inspect the wiring for any signs of damage or loose connections, as these can disrupt power flow to the fan. Finally, ensure that the fan blades are free from obstructions and in good condition, as any physical hindrance can prevent proper operation. By following this diagnostic approach, you can efficiently identify and address the underlying cause of your radiator fan's malfunction.
When troubleshooting a non-functioning radiator fan in a 1996 Toyota Corolla, it's crucial to consider several common problems that could be at play. A faulty fan motor is often the primary suspect, as it can fail to spin, leading to overheating. Additionally, a blown fuse in the fan circuit can interrupt the power supply, rendering the fan inoperative. It's also important to check the fan belt; if it's broken or loose, it won't drive the fan effectively, compromising the cooling system. Another potential issue is a faulty temperature sensor, which may fail to signal the fan to activate when the engine reaches a certain temperature, resulting in overheating. Lastly, a coolant leak can lead to insufficient coolant circulation, causing the radiator fan to malfunction. Addressing these issues promptly is essential to maintain optimal engine temperature and prevent serious damage to your vehicle.
When considering the urgency of repairing a non-functioning radiator fan in a 1996 Toyota Corolla, it is essential to recognize the critical role this component plays in engine health. The radiator fan is responsible for cooling the engine by dissipating heat, and without it functioning properly, the engine is at a heightened risk of overheating. This overheating can lead to severe consequences, including damage to vital engine parts such as the cylinder head gasket and pistons, which can result in costly repairs or even a complete engine failure. Additionally, neglecting to address this issue can lead to the breakdown of engine oil and coolant, further complicating the situation and increasing repair costs. Therefore, it is imperative to prioritize the repair of the radiator fan to ensure the vehicle operates efficiently and to safeguard against potential engine damage. Taking prompt action not only protects your investment but also enhances the longevity and reliability of your vehicle.
