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 a non-working radiator fan in a 2013 Smart Fortwo, it's essential to adopt a systematic approach that begins 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 prevent the fan from operating. If the fuse is intact, the next step is to inspect the relay that controls the fan; a malfunctioning relay can disrupt the power supply to the fan. Following this, test the fan motor directly by applying power to it; if the motor fails to spin, it may need replacement. Additionally, ensure that the temperature sensor is functioning correctly, as it is responsible for signaling the fan to activate when the engine reaches a certain temperature. Don’t overlook the wiring and connections; any loose or damaged wires can impede the fan's operation. Finally, using a diagnostic tool to scan for error codes can provide valuable insights into any underlying issues affecting the radiator fan system. By following this structured diagnostic approach, you can efficiently identify and resolve the problem with your radiator fan.
When diagnosing why the radiator fan in a 2013 Smart Fortwo has stopped working, it's crucial to consider several common problems that could be at play. A faulty fan motor is often the primary suspect, as it can fail to spin and thus fail to cool the engine effectively. Additionally, a blown fuse in the fan circuit can interrupt the power supply, rendering the fan inoperative. Inspecting the fan blades is also important; if they are damaged or broken, the fan will struggle to generate the necessary airflow. Another potential issue is a faulty temperature sensor, which may fail to signal the fan to activate, leading to overheating. Lastly, wiring issues can prevent the fan from receiving power, so checking the connections and wiring integrity is essential. Addressing these problems promptly is vital to avoid engine overheating and ensure the longevity of your vehicle. Regular maintenance and inspections can help catch these issues early, allowing for a smoother DIY repair process.
Addressing the repair of a non-functioning radiator fan in a 2013 Smart Fortwo is of utmost urgency due to the significant risks associated with engine overheating. The radiator fan is essential for maintaining optimal engine temperature by effectively cooling the radiator; without it, the engine is at a high risk of overheating. This overheating can lead to catastrophic damage, including the failure of vital components such as the cylinder head gasket and pistons, which can result in expensive repairs or even complete engine replacement. Furthermore, prolonged overheating can warp cylinder heads and damage the water pump, compounding repair costs and potentially leaving you with a vehicle that is no longer operational. Therefore, it is crucial to prioritize the repair of the radiator fan to ensure the vehicle's reliability and longevity, safeguarding against the severe consequences of engine damage.
