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.
To effectively diagnose the non-working radiator fan in your 1998 Chevrolet Malibu, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue that can prevent the fan from operating. If the fuse is intact, proceed to examine the relay, as it plays a crucial role in supplying power to the fan. A malfunctioning relay can disrupt the fan's operation, so testing it is essential. Next, test the fan motor directly by applying power to it; if it fails to turn on, the motor may need replacement. Additionally, check the temperature sensor, which signals the fan to activate when the engine reaches a certain temperature; a faulty sensor can hinder this process. Don’t overlook the wiring connected to the fan; inspect for any damage or loose connections that could interrupt the power supply. Lastly, ensure that your coolant levels are adequate, as low coolant can lead to overheating and trigger safety mechanisms that disable the fan. By following this structured diagnostic approach, you can identify and address the issue with your radiator fan effectively.
When diagnosing why the radiator fan in a 1998 Chevrolet Malibu has stopped working, it's essential to consider several common issues that could be at play. One primary culprit could be a faulty fan assembly, which may prevent the fan from operating altogether. Additionally, the fan clutch, responsible for engaging and disengaging the fan based on engine temperature, might be malfunctioning, leading to ineffective cooling. Another critical component to inspect is the coolant temperature sensor; if this sensor fails, it may not signal the fan to activate, resulting in overheating. Understanding these potential failure modes can empower DIYers to systematically check each component, ensuring that the cooling system functions correctly and preventing further engine damage. If these components are found to be defective, replacing them can restore the radiator fan's operation and maintain optimal engine temperature.
Repairing the non-functioning radiator fan in a 1998 Chevrolet Malibu is an urgent matter that should not be overlooked. The radiator fan is essential for regulating the engine's temperature by dissipating heat generated during operation. When this component fails, the risk of engine overheating significantly increases, which can lead to severe damage such as warped cylinder heads or blown head gaskets. These issues not only result in costly repairs but can also compromise vehicle safety, as an overheating engine may stall unexpectedly while driving. Furthermore, neglecting to address a faulty radiator fan can diminish engine performance and fuel efficiency, ultimately affecting the vehicle's reliability. Therefore, it is crucial to prioritize the repair of the radiator fan to ensure the longevity and safe operation of your Chevrolet Malibu.
