Engine Squeaking Easy step by step guide on how to repair automotive engine squeaking noises, this information pertains to most vehicles. Helpful Information Squeaking sounds are created when metal is contacting metal combined with a linear motion. Detection of a squeaking noise can be difficult, moving around the engine compartment at various levels can help find the origin of the noise. Difficulty Scale: 4 of 10 Begin with the vehicle on level ground engine off (cold) with the emergency brake set. Step 1  - A serpentine belt is designed to supply power to the accessories of the engine such as coolant pump, alternator and power steering. When this item wears it can make a squeaking or squealing noise. New Serpentine Belt Step 2  - Most pulleys, including the serpentine belt tensioner are supported by a sealed roller bearing, if this bearing fails it can cause a squeaking squealing noise. Serpentine Belt Tensioner Step 3  - A idler pulley is used...

Car Engine Makes Vibrating Noise Helpful Information Because vibrations are slightly different than other automotive related noises it can be difficult to detect the origin of the generation point, this condition can travel away from the actual cause and show up in a completely different place, this transference of vibration noise is called telescoping. Easy to follow step by step guide on how to repair an automotive engine vibration, this information is listed in the order of probability and pertains to most vehicles. Difficulty Level - 5 Step 1  - When an engine is misfiring it will vibrate as the balance of the engine has been disrupted.  Misfiring Spark Plug Step 2  - When an engine mount fails it will allow the engine to contact the vehicle frame creating a vibration. Replace Engine Mount Step 3  - If a serpentine belt tensioner fails it can "bounce" causing the engine to vibrate as the belt loses grip and then regains it. New Serpentine ...

Car Engine Makes Scraping Noise While Driving Helpful Information A scraping sound is typically created when metal is contacting metal during linear or rotational movement. Rotating objects are generally prone to scraping noises because they have close tolerances and are positioned near stationary objects. Some scrapping noises are easily fixed by re-positioning a particular brace or shield, while bearing failures need to be replaced. Easy step by step guide on how to repair an automotive engine scraping noises, this information pertains to most vehicles. Difficulty Scale: 4 of 10 Begin with the vehicle on flat ground, in park with the emergency brake "ON" and the engine "OFF". Step 1  - A bearing style of support pulley is used to keep tension on the serpentine belt, these bearings can fail causing a scraping noise which follows the engine speed. Serpentine Belt Tensioner Bearing Step 2  - A starter motor utilizes 12 volts to crank the engine ov...

Car Engine Makes Noise While Driving Noisy Car Engine Helpful Information Today's engines have been designed with more complexity and moving parts than ever before. Most of the time when you hear abnormal noises there is something going wrong. Excess engine noise is due to excessive clearance between two internal metal parts that should have little to no clearance. This clearance can be due to many things from a broken valve spring to a crankshaft bearing that has failed. The first step is to identify where the engine noise is being generated, with the engine running isolate where the noise is coming from in the engine, either the upper half, lower half, front half or rear half. (note: listen from above the engine or below the engine as this will help determine where to start looking for the cause of the noise. Crankshaft Bearing Best Practices To avoid engine noises change your engine oil every 3,000 to 5,000 miles with normal motor oil, and 6,000 to 8,000 miles wit...
