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.
To effectively diagnose the non-functioning radiator fan in your 2018 Mitsubishi Mirage G4, begin with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Start by inspecting the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue that can halt fan operation. If the fuse is intact, proceed to examine the relay, as it plays a crucial role in supplying power to the fan. A malfunctioning relay can prevent the fan from activating, so testing its functionality is essential. Next, test the fan motor directly by applying power to it; if it fails to operate, replacement may be necessary. Additionally, check the temperature sensor, which signals the fan to engage when the engine reaches a specific temperature; a faulty sensor can disrupt this process. Ensure that all wiring and connections are secure and undamaged, as faulty wiring can also impede fan operation. Finally, consider using an OBD-II scanner to check for any diagnostic trouble codes that may provide further insight into the cooling system's issues. By following this structured diagnostic approach, you can efficiently identify and resolve the underlying problem with your radiator fan.
When diagnosing the radiator fan issue in a 2018 Mitsubishi Mirage G4, it's important to systematically explore several common problems that could be causing the malfunction. A faulty fan motor is often the leading cause, as wear and tear can lead to its failure, necessitating a replacement to restore functionality. Additionally, a blown fuse can disrupt the electrical circuit, so checking the fuse box for any damaged fuses is a critical step in your troubleshooting process. Another potential issue is a malfunctioning temperature sensor, which may fail to signal the fan to turn on when the engine reaches the necessary temperature; replacing this sensor can often resolve the problem. Wiring issues, such as frayed or loose connections, can also prevent the fan from receiving power, making it essential to inspect the wiring for any signs of damage. Lastly, low coolant levels can contribute to overheating, which may cause the fan to stop working; therefore, ensuring that the coolant is topped up is also vital. By addressing these common causes, you can effectively troubleshoot and potentially resolve the radiator fan issue in your Mitsubishi Mirage G4.
Addressing the issue of a non-working radiator fan in a 2018 Mitsubishi Mirage G4 is of utmost urgency to prevent engine overheating. The radiator fan is essential for regulating the engine's temperature by dissipating heat generated during operation. When this component fails, the engine is at a heightened risk of overheating, which can lead to severe consequences such as warped cylinder heads, blown head gaskets, or even complete engine failure. Additionally, an overheating engine can compromise performance, increase emissions, and create safety hazards, particularly if the vehicle breaks down unexpectedly. Therefore, it is crucial to act swiftly in repairing the radiator fan to avoid costly repairs and ensure the longevity and reliability of your vehicle. Prompt attention to this issue not only safeguards your engine but also enhances your driving experience by maintaining optimal performance.
