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 CT5, start by examining the simplest components to rule out basic problems. Begin with the electrical system, checking the fuse associated with the radiator fan to ensure it hasn't blown. If the fuse is intact, inspect the ground connection located on the passenger side near the fog lights, as a poor ground can disrupt fan operation. Next, assess the fan assembly and the coolant temperature sensor, as these are common culprits for fan malfunctions. If the fan still does not operate, consider testing the fan motor and its controller by using a jumper wire to bypass the input signal, which can help determine if the issue lies with the fan itself or the control system. Additionally, keep an eye on the vehicle's computer response; if it triggers codes related to the fan, it may force the fan to run at full speed or shut off the AC, indicating a need for further investigation into the sensor or thermostat. By following this methodical approach, you can effectively diagnose and resolve radiator fan issues, ensuring your Cadillac CT5 runs smoothly.
When diagnosing a non-working radiator fan in your Cadillac CT5, it's essential to understand the common problems that could be at play. Start by examining the sensors and switches that signal the fan to activate; these components can often fail, preventing the fan from turning on. Next, inspect the fan assembly and the fan clutch, as well as the coolant temperature sensor, since any malfunction in these parts can disrupt the fan's operation. Additionally, consider the fan control module, which may be responsible for regulating the fan's activity in certain configurations. Testing the radiator fan motor itself is crucial, as a faulty motor will not operate regardless of other components' conditions. Keep an eye on the temperature gauge on your dashboard; if it shows incorrect readings, it could indicate a deeper issue. Finally, observe the fan's behavior when the vehicle is running and after it has been turned off, as a properly functioning fan should continue to run for a short period post-shutdown. By systematically checking these common failure points, you can effectively identify the cause of your radiator fan's malfunction.
When the radiator fan in your Cadillac CT5 is not functioning, it is crucial to address the issue promptly to avoid serious engine damage or overheating. A malfunctioning fan can lead to elevated engine temperatures, which may cause the engine to overheat, resulting in costly repairs or even complete engine failure. Additionally, if the fan assembly, fan clutch, or coolant temperature sensor is faulty, it can trigger emissions codes, potentially affecting your vehicle's performance and compliance with environmental regulations. Ignoring these symptoms not only compromises your vehicle's safety but can also lead to more extensive and expensive repairs down the line. Therefore, if you notice any signs of a non-working radiator fan, such as unusual engine temperatures or warning lights on your dashboard, it is essential to investigate the issue immediately to ensure the longevity and reliability of your Cadillac CT5.
