In case you're shopping for new aftermarket auto parts or looking to diagnose and fix cooling fan issues, this article has got you covered as well.
Signs of a Bad Cooling Fan Relay
When your car's cooling fan relay starts to falter, it can lead to a wide range of problems that shouldn't be ignored at all. Here are some indicative signs to watch out for.
Excessive Heating of Engine: An excessive heating of engine or overheating engine is mostly the first sign that something is wrong with your cooling system. If your temperature gauge spikes into the red zone or you seem to see steam coming out from under the hood, it's time to take a much more critical look as this could mean danger for your cooling system.
Troubles With Air Condition: A faulty cooling fan relay can have a major effect on your car's air conditioning performance. If you notice that your car’s air condition isn't blowing cold air as it should, the cooling fan could be the culprit. This is mostly because the air condition condenser has failed hence it will not be able to receive any power to cool it.
Unusual Engine Noise: A malfunctioning cooling fan relay might produce strange noises from the engine bay. Listen for grinding, squealing, or rattling sounds, which could indicate problems with the fan motor or its components. Pay close attention to this as it could mean that your cooling fan system could be damage or the cooling fan is damaged.
Visible Coolant Leaks: The cooling fan relay's malfunction can result in irregular temperature control, leading to excessive pressure within the cooling system. This pressure could cause coolant leaks, leaving behind noticeable puddles underneath your car. This should be address immediately as it could cause overheating.
Engine Warning Light: If your car's onboard diagnostic system detects problems with the cooling fan relay or the associated components, it might trigger the "Check Engine" light on your dashboard. With this, park the car and check the engine thoroughly.
How To Check if Radiator Fan is Working
Before making your deductions and jumping into conclusions, it's important to make sure that your radiator fan is indeed causing the problems. Here's a detailed step-by-step guide to help you check its functionality.
Safety First: Make sure your engine is turned off and has had sufficient time to cool down. You wouldn’t want to have steam come out from the engine when you open the hood so this step is very crucial.
Visual Inspection: Inspect the cooling fan for any visible signs of damage, such as broken blades or disconnected wiring. If you don’t see any damage done, then the problem might not necessary be from your radiator. You can still get expert opinion if you are not sure.
Manual Spin Test: Gently attempt to turn the fan blades by hand. If they move freely without resistance, it might indicate a problem with the fan motor. The fan motor could be damaged and need to be replaced.
Relay Testing: Use a multimeter to test the cooling fan relay's electrical connections. Refer to your car's manual for specific instructions on locating and testing the relay. If you cannot find the manual or you don’t know how to go about it, please contact a professional to help you.
Summing it up, your car's cooling system is essential for smooth operation, and a malfunctioning cooling fan relay can lead to various problems, including engine overheating and faulty air conditioning. By recognizing the symptoms of a bad cooling fan relay and learning how to check the radiator fan's functionality, you can take proactive steps to maintain your vehicle's performance.
