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 Lancer, it's essential to adopt a methodical diagnostic approach. Begin by inspecting the fan motor and clutch to ensure they are operational; a malfunction here is often the most straightforward issue to resolve. Next, check the fan relay and fuse located in the fuse block under the hood, as these components can easily fail and are relatively simple to replace. Following this, verify the coolant temperature sensor, which plays a crucial role in signaling the fan to activate. If these initial checks do not reveal the problem, turn your attention to the fan control module mounted on the back of the fan, as a faulty module can disrupt the fan's operation. By following this step-by-step process, you can effectively identify and address the root cause of your radiator fan issues, ensuring your Mitsubishi Lancer runs smoothly. Engaging with online forums or communities dedicated to Mitsubishi Lancer enthusiasts can also provide valuable insights and support throughout your troubleshooting journey.
When troubleshooting a non-working radiator fan in your Mitsubishi Lancer, it's essential to examine several critical components that may be at fault. Start with the fan assembly itself, as it is often the primary culprit behind fan malfunctions. If the assembly is damaged or has a faulty motor, it will prevent the fan from operating effectively. Next, consider the fan clutch, which is responsible for engaging the fan when needed; a malfunction here can lead to inadequate cooling. Additionally, the coolant temperature sensor is vital for regulating the fan's operation based on engine temperature, so ensure it is functioning correctly. If you notice that the fans only activate when the air conditioning is on, this could indicate an issue with the AC system's control over the fan operation. Lastly, if you find yourself manually activating the fan, it may point to a problem with the fan relay or the control system, which could require further investigation. By systematically checking these components, you can identify the root cause of the issue and take the necessary steps to restore your radiator fan's functionality.
When the radiator fan in your Mitsubishi Lancer fails to operate, it’s crucial to address the issue promptly to avoid overheating and potential engine damage. Common culprits include a faulty fan assembly, a malfunctioning fan clutch, or a defective coolant temperature sensor. Additionally, the fan is controlled by a module and a relay, which can also be sources of failure. If the fan operates at both high and low speeds but doesn’t activate automatically, this could indicate a problem with the control module or relay. Ignoring these symptoms can lead to severe consequences, including engine overheating, which poses significant safety risks and could result in costly repairs. Therefore, diagnosing and fixing the issue as soon as possible is essential for maintaining your vehicle's performance and safety.
