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.
When diagnosing a non-functioning radiator fan in your 2012 Fiat 500, it's essential to adopt a systematic approach that begins with the simplest solutions. Start by checking the coolant level and inspecting the fuse, as these are straightforward fixes that can often resolve the issue. If the fuse is burnt, replace it with one of the same size and type, but be aware that if it blows again, this could indicate a more serious problem such as an electrical short or excessive draw. Next, utilize a 12-volt test light to assess the Radiator Fan Control circuit in the harness connector, ensuring to actuate the High Speed Fan Relay with a scan tool for accurate readings. It's important to remember that the symptom of a non-working fan can be misleading; engine overheating may stem from various issues, so thorough diagnostics are crucial before replacing any components. Additionally, keep an eye out for common signs of radiator fan failure, like engine overheating, as a functioning fan is vital for maintaining optimal coolant temperatures. If necessary, you can test the relay by bridging the connections to see if the fan activates, helping you pinpoint whether the issue lies with the fan itself or the relay signal. By following this structured diagnostic approach, you can effectively identify and address the problem with your radiator fan.
When troubleshooting the radiator fan issues in a 2012 Fiat 500, it's crucial to understand the common problems that may arise. Electrical issues are often at the forefront, as a malfunctioning electrical system can prevent the fan from receiving the necessary power. Start by checking the fuse associated with the radiator fan; a blown fuse is a simple yet frequent cause of failure. Additionally, inspect the relays, as faulty relays can disrupt the fan's operation. The coolant temperature sensor is another critical component; if it fails to signal the fan to activate, the engine may overheat. It's also worth considering the air conditioning system, as problems here can affect the fan's performance when the AC is engaged. Don't overlook the wiring, as damaged or corroded wires can lead to operational issues. Lastly, the radiator fan motor itself may be defective, requiring a thorough examination to ensure it functions correctly. By systematically addressing these potential problems, you can effectively diagnose and resolve the radiator fan issues in your Fiat 500, ensuring optimal cooling system performance.
Fixing the radiator fan in your 2012 Fiat 500 is an urgent matter that should not be overlooked. The radiator fan is essential for regulating the engine's temperature, and if it fails, the risk of overheating increases significantly. An overheating engine can lead to severe damage, such as a blown head gasket, which can result in costly repairs and extensive downtime for your vehicle. Moreover, the longer you wait to address a malfunctioning radiator fan, the more likely you are to encounter additional complications that could compromise your car's performance and safety. Therefore, it is crucial to diagnose and repair any issues with the radiator fan promptly to ensure your engine remains within safe operating temperatures and to avoid the financial burden of major repairs down the line. Taking immediate action not only protects your investment but also ensures your vehicle operates reliably and safely.
