![]() The crankshaft harmonic balancer is part of the crankshaft. Then, check for rust, cracks, or missing bolts. If this is the case, you would have to remove the flexplate cover. The flexplate will start to wobble and will most definitely produce rattling noise. If your vehicle has a broken flexplate, the connection between the crankshaft and the torque converter would be compromised and it won’t run smoothly. ![]() Its purpose is to absorb vibrations, but if it weakens or cracks over time, it can start making rattling noises. The flexplate or a flex-shock device is found in cars with automatic transmissions and has a function to connect the crankshaft to the torque converter and improve smooth running.Ī flexplate is an integral part of any car with an automatic transmission and serves as a connection between the engine and the transmission. You must always change your timing belt if you notice any cracks to avoid any additional damage to the engine. If the timing belt or the timing belt tensioner gets damaged, it will get loose and will start to vibrate and make a rattling noise. When the timing belt is broken, however, this communication is hindered or disrupted, causing mechanical components to work against each other rather than with each other which produces a rattling sound in the process. The timing belt has to be under certain tension which is allowed by a timing belt tensioner.Ī broken timing belt may cause the engine to make a rattling noise because the timing belt synchronizes the camshaft and crankshaft of an engine, allowing them to communicate with one another seamlessly. The timing belt has a function to connect the engine crankshaft to the camshaft which allows the valves to open and close at the correct timing with the position of the pistons. You would need to check every mounting bracket nut or bolt to make sure that there is nothing loose. If one of these mounting brackets is broken, the component that the bracket is holding will start to vibrate and make a rattling noise. Mounting brackets are used to support various accessories such as the power steering pump compressor and air pump, as well as to attach the engine to the vehicle frame.Ī broken or worn mounting bracket will allow the engine to move freely, creating vibration and rattling noise while running. The third thing that could be making a rattling noise is a broken mounting bracket. If you drive your car with a broken serpentine belt, the engine would overheat because the water pump won’t work. The car won’t be drive-able and you would have to call a towing truck. If the serpentine belt breaks, your engine would start making a rattling noise. When the serpentine belt gets cracked or completely broken, it can make a rattling noise because it will get loose and hit vital engine components. The difference is that the timing belt runs the engine camshaft and in most cases, you cannot see it because it is hidden under protective covers, whereas the serpentine belt is visible. Very often the serpentine belt is mistaken for a timing belt. The serpentine belt has a function to drive your alternator, water pump, and air conditioner compressor. ![]() Cracked or Broken Serpentine BeltĪll diesel or gasoline cars have a serpentine belt. If the engine oil level is really low and the engine is rattling after the oil has been added, permanent damage could have occurred and replacement is needed for whichever part is been damaged. If your engine has low oil, it can cause rattling sounds due to poor or no lubrication for vinyl engine components.Įngine oil is used to keep components lubricated and prevent damage due to friction, and as the level drops, more metal-to-metal contact can occur which causes vibrations that translate into the telltale rattling sound.Ĭheck engine oil level and add if needed. If your engine is making a rattling noise, the first thing to suspect is low engine oil. Here are the top 8 reasons why your car engine is making a rattling noise: 1. However, if your engine starts making a rattling noise, that is far from normal. The engine has many moving parts which all make some kind of noise.
