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 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 faced with a non-functioning radiator fan in a 2016 Cadillac ATS, it's essential to adopt a systematic diagnostic approach to identify the root cause. Begin by checking the fuse associated with the radiator fan, as a blown fuse is a straightforward and common issue that can easily be resolved. Next, inspect the relay that controls the fan; a malfunctioning relay can disrupt the fan's operation and is relatively simple to replace. If these initial checks do not resolve the issue, proceed to test the radiator fan motor itself to ensure it is operational, as a faulty motor will require replacement. Additionally, verify that the coolant level is adequate, as low coolant can lead to overheating and affect fan performance. The temperature sensor is another critical component to examine, as it triggers the fan when needed; ensuring it is functioning correctly is vital. Finally, inspect all wiring and connections for any signs of damage or looseness, as these can impede the fan's operation. By following this structured approach, you can effectively diagnose and address the radiator fan issue in your Cadillac ATS, ensuring your vehicle runs smoothly.
When diagnosing why the radiator fan in a 2016 Cadillac ATS is not functioning, it's essential to consider several common problems that could be at play. One of the primary culprits is the fan assembly itself, which may have electrical issues or physical damage preventing it from operating. Additionally, the fan clutch, responsible for engaging the fan when needed, can fail, leading to inadequate cooling. Another critical component to examine is the coolant temperature sensor; if it malfunctions, it may not signal the fan to turn on, resulting in overheating. By systematically checking these components, DIY enthusiasts can effectively troubleshoot and resolve the issue, ensuring the vehicle's cooling system remains efficient and reliable.
When it comes to the non-functioning radiator fan in a 2016 Cadillac ATS, the urgency of repair cannot be overstated. A malfunctioning fan directly impacts the engine's cooling system, leading to inadequate temperature regulation, particularly during low-speed driving or idling. This situation can quickly escalate to engine overheating, which not only risks severe damage to the engine but also poses significant safety hazards while driving. Although the air conditioning system may still operate without the fan, it can exacerbate overheating issues under certain conditions, making it crucial to address the fan's malfunction without delay. The time a vehicle can operate without a functioning radiator fan varies, but the general consensus is that prompt action is necessary to prevent further complications and costly repairs. Therefore, if you notice any signs of a failing radiator fan, it is essential to prioritize its repair to ensure the longevity and safety of your vehicle.
