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 Toyota 86, start with the simplest checks before moving on to more complex diagnostics. Begin by ensuring that the fan assembly is intact and that there are no visible signs of damage or disconnection. Next, use a multimeter to test if the fans are receiving power; this can be done with the car both on and off, as well as with the AC activated. If power is reaching the fans but they are still not operational, consider inspecting the fan clutch and coolant temperature sensor, as these components are often culprits in fan malfunctions. Additionally, if both the AC and radiator fans are unresponsive, check the 30A fusible link in the fuse box, as a blown fuse can disrupt power to the fans. For those looking to enhance performance, upgrading to electric cooling fans with adjustable temperature sensors and a custom radiator shroud can eliminate the need for a fan clutch and improve overall efficiency. By following this structured approach, you can effectively diagnose and resolve radiator fan issues, ensuring your Toyota 86 runs smoothly.
When diagnosing and fixing a non-working radiator fan in a Toyota 86, it's essential to understand the common problems that can arise within this system. One frequent issue is a low coolant level, which can prevent the fan from operating effectively. Additionally, a blown fuse can disrupt the electrical flow necessary for the fan to function. If these initial checks are clear, the next step is to inspect the wiring and the fan itself for any signs of damage or wear. A malfunctioning radiator fan relay is another common culprit, as it plays a critical role in activating the fan when needed. Testing the electric radiator fans by connecting them directly to a battery can help determine if the motors are faulty. Furthermore, the coolant temperature sensor should be examined, as it signals the engine control unit (ECU) to engage the fan based on temperature readings. If any components, such as the fan motor or relay, are found to be defective, replacing them promptly will restore the radiator fan's functionality. By being aware of these common problems, you can effectively troubleshoot and resolve issues with your radiator fan, ensuring your Toyota 86 runs smoothly.
Addressing a non-working radiator fan in your Toyota 86 is not just a matter of convenience; it is essential for the health of your vehicle. When the radiator fan fails, the engine is at risk of overheating, which can lead to catastrophic damage such as warped cylinder heads or a blown head gasket. These repairs can be incredibly costly and time-consuming, making it crucial to act swiftly. The radiator fan is vital for regulating the engine's temperature by cooling the radiator and dissipating heat generated during operation. If this component is neglected, you may experience diminished engine performance and efficiency, as the engine struggles to maintain optimal operating conditions. By promptly addressing the issue of a non-working radiator fan, you not only safeguard your engine from severe damage but also enhance the overall reliability and longevity of your Toyota 86, ensuring that it continues to perform at its best.
