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 faced with a non-functioning radiator fan in your 2018 Chevrolet Suburban 3500 HD, it's essential to adopt a methodical diagnostic approach. Begin by checking the fuse associated with the radiator fan; a blown fuse is a straightforward issue that can easily be resolved. Next, inspect the relay that controls the fan, as a malfunctioning relay can disrupt the fan's operation. If these components are functioning correctly, proceed to test the fan motor itself, as a defective motor will require replacement. Additionally, examine the wiring connected to the fan for any signs of damage or loose connections, as these can impede power delivery. Utilizing a diagnostic scanner to check for error codes can provide further insights into any underlying issues. Lastly, ensure that the coolant levels are adequate, as low coolant can lead to overheating and affect fan performance. By following this structured approach, you can effectively diagnose and address the radiator fan issue, empowering you to take control of your vehicle's maintenance.
When troubleshooting a non-working radiator fan in a 2018 Chevrolet Suburban 3500 HD, it's crucial to consider several common problems that could be at play. A faulty fan motor is often the primary suspect, as it can fail to spin, leading to overheating. Additionally, a blown fuse in the fan circuit can interrupt the power supply, rendering the fan inoperative. Another potential issue is a defective relay, which is responsible for sending the electrical signal to the fan; if this component fails, the fan won't receive the necessary power to function. It's also important to inspect the fan blades themselves, as any damage or breakage can hinder their ability to rotate effectively. Lastly, issues with the coolant temperature sensor can prevent the fan from activating at the appropriate temperature, exacerbating cooling problems. Addressing these issues promptly is essential to maintain the vehicle's cooling system and prevent engine damage.
When it comes to the radiator fan in your 2018 Chevrolet Suburban 3500 HD, the urgency of repair cannot be overstated. A malfunctioning radiator fan can lead to severe engine overheating, which poses a significant risk to your vehicle's overall health. If the engine overheats, it may not only cause immediate performance issues but can also result in catastrophic damage, such as warped cylinder heads or a blown head gasket. These repairs can be incredibly costly and time-consuming, often leading to a complete engine replacement if the problem is left unaddressed. Additionally, an overheating engine can lead to unexpected shutdowns, leaving you stranded and potentially facing dangerous situations on the road. Therefore, if you notice any signs of a failing radiator fan, such as unusual noises or a warning light on your dashboard, it is crucial to act quickly. Prioritizing this repair will not only save you from expensive future repairs but also ensure the safety and reliability of your vehicle.
