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 troubleshooting radiator fan issues in your Cadillac ELR, start with the basics to identify the problem efficiently. Begin by checking the fan relay and fuse, as these are often the simplest components to inspect and can easily be replaced if faulty. Next, manually spin the fan blade to ensure there are no obstructions that could hinder its movement. If the fan operates freely, proceed to examine the coolant temperature sensor, as it plays a vital role in regulating fan operation. Regular maintenance is crucial; ensure the coolant level is adequate and that the radiator fins are clean to promote optimal airflow and cooling efficiency. If you notice symptoms like engine overheating, particularly in stop-and-go traffic, it may indicate a more serious issue that requires further investigation. By following this diagnostic approach, you can effectively pinpoint and resolve radiator fan issues, ensuring your Cadillac ELR runs smoothly and efficiently.
When diagnosing a non-working radiator fan in a Cadillac ELR, it's crucial to be aware of the common problems that can affect this system. Start by checking the fuse for the electric radiator fans, as a blown fuse can completely disable the fan's operation. If the fuse is intact, inspect the fan for any obstructions that might prevent it from spinning freely. Testing the fan's functionality can be done by running the vehicle with the A/C set to maximum; if the fan engages, the issue may have been resolved. However, if the fan remains inactive, it could signal more complex issues, such as a malfunctioning coolant thermostat or problems related to A/C system pressure. Recognizing these common failure modes will help you effectively troubleshoot and resolve radiator fan issues in your Cadillac ELR, ensuring that your vehicle maintains optimal cooling performance.
When the radiator fan in your Cadillac ELR is not functioning, it is crucial to address the issue promptly to avoid severe engine damage or overheating. A malfunctioning fan can lead to increased engine temperatures, which may cause the engine to overheat, resulting in costly repairs or even complete engine failure. Additionally, if the fan is not operating, it can affect the performance of the A/C system, leading to discomfort during hot weather. Common culprits for fan failure include a blown fuse, a faulty fan assembly, or issues with the coolant temperature sensor. Before diving into repairs, check the underhood fuse box for any blown fuses, as this is a simple fix that can restore functionality. If the fuses are intact, consider inspecting the fan assembly and coolant levels, as low coolant or air in the system can also hinder performance. Addressing these issues not only ensures your vehicle runs smoothly but also enhances your safety on the road. Taking the time to diagnose and resolve radiator fan problems can save you from more significant headaches down the line.
