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 troubleshooting radiator fan issues in your Mitsubishi Galant, begin with the most straightforward checks to avoid unnecessary complications. Start by inspecting the radiator cap to ensure that the cooling system is full, as a low coolant level can prevent the fan from operating correctly. Next, examine the serpentine belt for signs of wear, such as cracks or stretching, since a compromised belt can hinder fan performance. If the fan runs continuously, draining the battery, the coolant fan control module may be at fault, so consider testing or replacing it. Additionally, assess the fan assembly and the fan clutch, as these components are often responsible for fan malfunctions. Finally, if the problem persists, check the coolant temperature sensor and the fan switch, as bypassing a resistor may also help identify the issue. By following this diagnostic approach, you can systematically address the common causes of radiator fan problems and restore functionality to your vehicle.
When addressing the issue of a non-functioning radiator fan in a Mitsubishi Galant, it's crucial to systematically evaluate several key components that may be contributing to the problem. Begin with the fan assembly, as any physical damage or wear can hinder its operation. Next, inspect the fan clutch, which is vital for engaging the fan when necessary; a malfunction here can lead to insufficient cooling. The coolant temperature sensor is another critical element to examine, as it signals the fan to activate based on the engine's temperature; if this sensor is faulty, the fan may not turn on as needed. Additionally, check the fuses and relays associated with the cooling system, since a blown fuse or a defective relay can interrupt power to the fan. It's also important to consider the AC compressor, as its failure to engage can impact fan operation, especially in vehicles with integrated cooling systems. Lastly, ensure that the temperature sensor located at the bottom of the radiator is functioning correctly, as it directly affects the fan's performance. By thoroughly inspecting these components, you can effectively diagnose and resolve the issue with your radiator fan, ensuring your Mitsubishi Galant operates smoothly.
When the radiator fan in your Mitsubishi Galant is not functioning, it is crucial to address the problem without delay. Ignoring this issue can lead to severe consequences, such as engine overheating, which may result in costly repairs or even engine failure. Common culprits include a malfunctioning fan assembly, a faulty fan clutch, or a defective coolant temperature sensor. Additionally, a failed cooling fan relay can cause the fan to remain stuck in the "on" position, potentially draining your battery overnight. If the radiator or condenser fans are running continuously, the coolant fan control module may be at fault. Diagnosing the specific cause of the radiator fan failure is essential not only for the longevity of your vehicle but also for your safety on the road. Taking immediate action can help you avoid more significant issues down the line, ensuring your Mitsubishi Galant runs smoothly and efficiently.
