The most common reasons a 2016 Chevrolet SS radiator fan isn't working are the fan assembly, the fan clutch, or the coolant temperature sensor.
  • Fan Motor or Clutch: A faulty fan motor or a malfunctioning fan clutch can result in inadequate cooling, causing the engine to overheat.
  • Fan Relay or Fuse: A faulty fan relay or blown fuse can prevent the cooling fan from operating, leading to engine overheating.
  • Temp Sensor or Fan Control Module: A faulty temperature sensor or fan control module can result in incorrect readings, causing the engine to overheat or the cooling fan to operate improperly.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2016 Chevrolet SS radiator fan isn't working?

Common Repairs

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.

What are the steps to diagnose the non-functioning radiator fan in a 2016 Chevrolet SS?

To effectively diagnose a non-functioning radiator fan in your 2016 Chevrolet SS, begin with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Start by examining the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue that can halt fan operation. If the fuse is intact, proceed to inspect the relay, as a malfunctioning relay can prevent the fan from receiving power. Next, test the fan motor directly by applying power to it; if the motor spins, it indicates that the fan itself is operational. If the fan does not activate, further investigation is warranted. Check the temperature sensor, which is crucial for signaling the fan to turn on; ensure it is functioning correctly. Additionally, inspect the wiring and connections for any signs of damage or looseness that could disrupt the electrical flow. Finally, using a diagnostic scanner can help identify any error codes related to the cooling system, providing insight into more complex issues. By following this structured diagnostic approach, you can efficiently identify and resolve the problem with your radiator fan.

What are the common causes for the radiator fan not working in a 2016 Chevrolet SS?

When dealing with a non-functioning radiator fan in a 2016 Chevrolet SS, it's essential to understand the common problems that could be at play. One of the primary culprits is the fan assembly itself, which may have failed due to wear and tear or electrical issues. Additionally, the fan clutch, responsible for engaging the fan when needed, can also malfunction, leading to inadequate cooling. Another critical component to inspect is the coolant temperature sensor; if it fails to send the correct signals, the fan may not activate as required. Furthermore, don't overlook the serpentine belt, as it can stretch or crack over time, impacting the fan's operation. Addressing these components promptly is crucial, as driving without a functioning cooling fan can result in engine overheating, potentially causing severe damage. For those inclined to tackle this issue themselves, a thorough inspection of these parts can help identify the problem and guide you toward a solution.

How urgent is it to repair the non-working radiator fan in a 2016 Chevrolet SS to prevent engine overheating?

Repairing a non-working radiator fan in a 2016 Chevrolet SS is an urgent matter that should not be overlooked. The radiator fan is essential for regulating the engine's temperature by dissipating heat generated during operation. When this component fails, the engine is at a heightened risk of overheating, which can lead to catastrophic consequences such as warped cylinder heads or blown head gaskets. These issues not only result in costly repairs but can also compromise the vehicle's performance and safety. Overheating can cause the engine to lose power, increase emissions, and potentially lead to a breakdown, putting you and others on the road at risk. Therefore, addressing any signs of a malfunctioning radiator fan immediately is crucial for maintaining the vehicle's health and ensuring safe driving conditions. Taking prompt action can save you from significant repair costs and extend the lifespan of your engine and its components.
