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 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.
When faced with a non-functioning radiator fan in a 2009 Mercedes-Benz S63 AMG, it's essential to adopt a systematic diagnostic approach. Start by visually inspecting the fan for any obvious signs of damage or obstruction that could impede its operation. Next, examine the wiring harness connected to the fan; look for frayed wires or loose connections that might disrupt electrical flow. If these initial checks do not reveal the problem, proceed to test the radiator fan itself to confirm whether it is operational. Utilizing diagnostic tools, such as the SDS (Star) system, can also provide valuable insights into the issue, allowing for a more precise identification of faults. By following these steps, you can effectively narrow down the cause of the radiator fan malfunction and determine the necessary repairs.
When diagnosing the radiator fan issue in a 2009 Mercedes-Benz S63 AMG, it's crucial to understand the common problems that could lead to its malfunction. Start by checking the fuse linked to the fan; a blown fuse can halt operation, and if it repeatedly blows, this may signal an underlying electrical problem. Next, inspect the fan blades for any debris or obstructions that could impede their movement, as even minor blockages can prevent the fan from functioning properly. Additionally, examine the wiring harness for any signs of damage or wear, since compromised wiring can disrupt the fan's performance. If these components are intact, the fault may reside within the fan module itself. In some instances, replacing the electrical fan, the relay, the coolant temperature sensor, or the mechanical fan clutch may be necessary to restore functionality. By methodically addressing these common issues, you can effectively troubleshoot and resolve the radiator fan problem in your S63 AMG.
Addressing a non-working radiator fan in your 2009 Mercedes-Benz S63 AMG is an urgent matter that should not be overlooked. The radiator fan plays a vital role in regulating the engine's temperature, and when it fails, the risk of overheating increases significantly. This overheating can lead to severe engine damage, resulting in costly repairs and potential safety hazards. Ignoring the symptoms of a malfunctioning radiator fan can escalate the problem, leading to more extensive damage that could compromise the vehicle's performance and reliability. Therefore, it is crucial to diagnose and repair any issues with the radiator fan promptly to ensure the longevity of your engine and maintain the overall safety of your vehicle. Taking immediate action not only protects your investment but also enhances your driving experience by ensuring that your S63 AMG operates within its optimal temperature range.
