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 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-working radiator fan in your 2015 Ford Transit-350 HD, it's crucial to follow a structured diagnostic approach that emphasizes simpler checks before moving on to more complex issues. Start by examining the fuse linked to the radiator fan, as a blown fuse is a frequent culprit and an easy fix. If the fuse is intact, the next step is to inspect the relay, which is responsible for supplying power to the fan; a faulty relay may need replacement. After that, test the fan motor to confirm it is receiving power and functioning properly, since a malfunctioning motor will prevent the fan from operating. Additionally, check the temperature sensor, as a defective sensor may fail to signal the fan to activate when required. It's also important to look for any wiring issues, such as damaged or loose connections, that could hinder the fan's performance. Lastly, ensure that coolant levels are sufficient, as low coolant can lead to overheating and impact the fan's operation. By systematically following these steps, you can effectively diagnose and resolve the issue with your radiator fan.
When diagnosing why the radiator fan in a 2015 Ford Transit-350 HD is not functioning, it's essential to consider several common issues that could be at play. Start by inspecting the fan assembly and the fan clutch, as these components are often the culprits behind fan failure. Additionally, the coolant temperature sensor plays a critical role in regulating fan operation, so ensure it is functioning correctly. Electrical issues are also prevalent; check for blown fuses or a faulty relay, as these can disrupt the power supply to the fan. Furthermore, examine the wiring for any signs of damage or short circuits that could prevent the fan from receiving the necessary voltage. Lastly, ensure that the coolant levels are adequate, as low coolant can trigger the fan to remain inactive. By systematically checking these components, you can effectively troubleshoot and resolve the issue with the radiator fan.
Addressing a non-working radiator fan in your 2015 Ford Transit-350 HD is not just a matter of convenience; it is a critical safety concern that demands immediate attention. A malfunctioning radiator fan can lead to engine overheating, which poses a significant risk of severe damage to your vehicle's components. This overheating can escalate to engine failure, leaving you stranded and potentially endangering your safety and that of others on the road. Moreover, neglecting this issue can adversely affect your vehicle's fuel efficiency and overall performance, leading to costly repairs down the line. Therefore, it is essential to diagnose and repair the radiator fan promptly to maintain the reliability and longevity of your vehicle, ensuring a safe driving experience. Taking swift action not only protects your investment but also enhances your peace of mind while on the road.
