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.
To effectively diagnose the non-functioning radiator fan in your 2011 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 halt fan operation. If the fuse is intact, proceed to examine the relay, which controls the power supply to the fan. A malfunctioning relay may require replacement to restore functionality. Next, test the fan motor directly by applying power to it; if it fails to operate, the motor itself may need replacement. Additionally, check the temperature sensor, as a faulty sensor may not signal the fan to activate when the engine reaches the necessary temperature. Lastly, inspect the wiring for any signs of damage or loose connections, as these can impede power delivery to the fan. If these steps do not resolve the issue, consulting a mechanic may be necessary for further diagnosis and repair. By following this structured approach, you can efficiently identify and address the problem with your radiator fan.
When diagnosing a non-functioning radiator fan in a 2011 Chevrolet Malibu, it's essential to consider several common issues that could be at play. One of the first things to check is the electrical system for a blown fuse, as this can easily disrupt the fan's operation. If the fuse is intact, the next step is to inspect the fan motor itself, which may have failed and requires replacement. Additionally, the temperature sensor plays a crucial role in signaling the fan to activate; if it's faulty, the fan may not turn on when needed. Another potential culprit is the fan belt; if it's broken or slipping, it can prevent the fan from spinning properly. Lastly, a coolant leak can lead to low coolant levels, causing the engine to overheat and the fan to stop working as a safety measure. By systematically checking these components, DIYers can effectively identify and resolve the issue with the radiator fan.
Addressing a non-functioning radiator fan in a 2011 Chevrolet Malibu is of utmost importance due to the significant risks associated with engine overheating. The radiator fan is essential for maintaining optimal engine temperatures by dissipating heat from the radiator. When this component fails, the engine is at a heightened risk of overheating, which can lead to severe damage such as warped components or even engine seizure. This not only results in costly repairs but can also leave you stranded on the road, necessitating towing services. Furthermore, an overheating engine can compromise the vehicle's overall performance and fuel efficiency, making it crucial to act swiftly. Therefore, if you notice any signs of a malfunctioning radiator fan, it is advisable to inspect and repair it promptly to safeguard your vehicle's health and avoid more extensive damage in the future.
