A girl in the road with headphones | Weiss Toyota of South CountyIf you’ve ever worried about things that go thump in the night, just wait until you hear the noises your car makes. Some of them can send shivers up the spine of even the most dedicated car owner. Car noises can spell trouble for your vehicle, especially if they occur on a regular basis or grow louder. Here are some noises from your car engine that you should never ignore.


Your car has different types of drive belts, like v-belts, serpentine belts, and timing belts. These belts move by the friction created with a pulley and are essential for transferring power from the engine to the various mechanical components like the alternator, water pump, air conditioner compressor, and power steering pump.
