Strange Sounds Cars Make and What They Mean
November 6th, 2018
Knocking – If you hear a knocking sound happening under your hood, there could be an issue with how the fuel is igniting in your engine. Specifically, the fuel is burning unevenly in your engine’s cylinders. Engine knocking can be prevented by using the correct spark plugs for your vehicle and using a higher-octane fuel at the gas pump. If your engine is making knocking noises, head to Milstead Automotive ASAP.

Squealing – If your engine is producing a high-pitched squealing noise, a belt is probably to blame. Most likely, it is time to replace or readjust your serpentine belt. Over time, this belt can slip and slide to a position where it yields the unmistakable squealing. If the squealing only happens when you apply your brakes, it’s probably time to replace them. Worn brakes can produce squealing, squeaking, or even a more metallic grinding sound. If you hear any of these while slowing down on the road, head to a shop immediately. Driving with faulty brakes should be avoided at all costs for your safety.
Thumping – Thumping is a noise most commonly heard coming from the exhaust on your vehicle. If your exhaust isn’t producing a thumping sound, it may just be louder than usual – in both cases, your exhaust system could be damaged. If you notice any unusual sounds coming from your exhaust, take your car to a mechanic soon. A damaged exhaust system could lead to a carbon monoxide leak inside your vehicle, which is extremely dangerous.
Tapping or Clicking – If you hear a tapping or clicking sound coming from beneath the hood, you could low on engine oil. If you check your oil level and it looks normal, the next thing to check out would be the oil pressure or a blockage in your system. Another explanation could be an issue with your valves.
