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 2016 Mercedes-Benz E350, begin with the simplest solutions before progressing to more complex diagnostics. Start by checking the fuse associated with the radiator fan, as a blown fuse is a common and easily fixable issue that can halt fan operation. If the fuse is intact, inspect the relay, which controls the power supply to the fan; a malfunctioning relay may need replacement. Next, test the fan motor directly by applying power to it; if it fails to operate, the motor itself may be defective and require replacement. Additionally, examine the temperature sensor, as it plays a crucial role in signaling the fan to activate when the engine reaches a specific temperature. If the sensor is faulty, it may not trigger the fan correctly. Lastly, inspect the wiring for any signs of damage or loose connections, as these can disrupt the power flow to the fan. If these steps do not resolve the issue, consulting a mechanic or dealership for professional assistance is advisable to ensure a thorough diagnosis and repair. By following this structured approach, you can efficiently identify and address the problem with your radiator fan.
When dealing with a non-functioning radiator fan in a 2016 Mercedes-Benz E350, it's essential to understand the common problems that could be at play. One of the primary culprits is a faulty fan motor, which may require replacement to restore the fan's operation. Additionally, a blown fuse in the fan circuit can disrupt power, so checking for any blown fuses is a crucial step in your troubleshooting process. Another potential issue is a malfunctioning temperature sensor, which may fail to signal the fan to activate when the engine reaches a certain temperature; replacing this sensor can often resolve the problem. Wiring issues, such as damaged or loose connections, can also prevent the fan from functioning properly, making it important to inspect the wiring thoroughly. Lastly, low coolant levels can lead to overheating, which may cause the radiator fan to stop working; ensuring that the coolant is at the appropriate level can help mitigate this risk. By systematically addressing these common causes, you can effectively diagnose and potentially fix the radiator fan issue in your vehicle.
Addressing a non-functioning radiator fan in your 2016 Mercedes-Benz E350 is critical for maintaining the health of your engine and ensuring your vehicle's reliability. The radiator fan is essential for regulating engine temperature by dissipating heat; without it, your engine is at risk of overheating. This overheating can lead to severe engine damage, including warped cylinder heads or a blown head gasket, which can result in costly repairs and leave you stranded. Moreover, a malfunctioning fan can compromise your vehicle's overall performance, causing it to run inefficiently and potentially leading to further mechanical issues. Therefore, if you notice that your radiator fan is not operating as it should, it is imperative to diagnose and repair the problem promptly. Ignoring this issue not only poses a safety risk but can also lead to significant long-term damage to your vehicle, making it essential to act quickly to ensure your car remains in optimal condition.
