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.
To effectively diagnose the non-functioning radiator fan in your 2016 BMW 535i GT, begin with a systematic approach that prioritizes simpler solutions before delving into more complex diagnostics. Start by checking the fuse associated with the radiator fan; a blown fuse is often the simplest issue to resolve. If the fuse is intact, inspect the fan itself for any visible damage, such as broken blades or signs of corrosion, which could indicate a need for repair or replacement. Next, conduct a functional test of the fan to determine if it operates correctly. Pay attention to symptoms like engine overheating, as this can signal a malfunctioning fan. If the fan fails to activate, consider potential causes such as a faulty starter relay, a defective fan motor, or issues with the vehicle's wiring or engine control module (ECM). By following this diagnostic approach, you can efficiently identify the root cause of the problem and take the necessary steps to restore your radiator fan's functionality.
When diagnosing why the radiator fan in a 2016 BMW 535i GT is not functioning, it's essential to consider several common problems that could be at play. One of the primary culprits is the fan assembly itself, which may have failed due to wear and tear or electrical issues. Additionally, the fan clutch can malfunction, preventing the fan from engaging when needed. Another frequent issue is the coolant temperature sensor, which may not be accurately relaying temperature data to the engine control unit, leading to improper fan operation. It's also important to check for a blown fuse or a faulty relay, as these components are critical for the electrical circuit that powers the fan. Furthermore, inspect for any broken wires that could disrupt the connection. Low coolant levels can also affect the fan's performance, as the system relies on adequate coolant to regulate temperature effectively. Lastly, a damaged fan blade or motor can directly impede the fan's ability to operate. By systematically checking these components, DIYers can effectively troubleshoot and resolve the radiator fan issue in their BMW 535i GT.
Addressing a non-working radiator fan in your 2016 BMW 535i GT is not just a matter of convenience; it is a critical maintenance task that requires immediate attention. A malfunctioning radiator fan can lead to severe engine overheating, which poses a significant risk of engine damage and costly repairs. When the radiator fan fails, the engine temperature can rise beyond safe levels, potentially resulting in warped cylinder heads or blown gaskets. Additionally, the longer you wait to fix the issue, the more likely you are to encounter additional complications, such as electrical problems or coolant leaks, which can further escalate repair costs. Therefore, if you notice that your radiator fan is not functioning, it is essential to diagnose and resolve the problem as soon as possible to ensure your vehicle operates safely and efficiently. Taking prompt action not only protects your engine but also saves you from the stress and expense of extensive repairs down the line.

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.
