Loud squealing or rattling is coming from engine Inspection
For those with little automotive experience, the area under the hood can be pretty mysterious. You know that when you press the gas pedal, the engine accelerates, and when you press the brake, the car slows down. You may know enough to change your air filter and check your oil level, but strange sounds coming from under the hood can be frightening and frustrating. If you’re hearing a squealing and/or rattling from under the hood, you’ll need to have it professionally inspected and repaired. The engine of your car actually provides the power for most of your accessory systems, such as the power steering, the air conditioner and more. A turning engine provides the means to operate a wide range of additional parts. This is done by using belts and pulleys. In modern vehicles, you generally only have one or possibly two belts. These are routed around multiple different pulleys located on the side of the engine (and attached to various components). As the engine spins, it turns the main pulley, which is attached to the camshaft. This main pulley drives the serpentine belt. The serpentine belt turns other pulleys, such as your alternator pulley, the power steering pump pulley and others. This provides the power for those systems to operate. Of course, this does require that your belts are in good condition, and that your pulleys are working normally. Over time and through normal wear and tear, belts will stretch, crack and break. Pulleys will also experience problems (generally due to bearing failure over time).
A top-rated mobile mechanic will come to your home or office to inspect the engine, belts, pulleys and other components, and to listen to the squealing or rattling from the engine. The mechanic will then provide a detailed inspection report that includes the scope and cost of the necessary repairs. The mechanic will need to inspect the vehicle, including listening to the squealing or rattling noise from the engine. Next, the mechanic will visually inspect the belts and pulleys to ensure that both are in good repair. If the noise does not occur when the engine is idling, it may be necessary for the mechanic to test drive the car to duplicate the symptoms and gain a better understanding of the problem.
If the squealing or rattling sound from the engine is caused by either a belt or pulley, time is of the essence in addressing the issue. A loose belt can quickly progress from squealing to breaking, potentially leaving you stranded on the side of the road. If the problem stems from a worn pulley, it’s possible that it will eventually seize, which means that whatever accessory it operates will no longer work, and that there’s a chance the belt will break. The best way to prevent problems like this from becoming serious issues is to have your belts and pulleys professionally inspected during routine maintenance services. If you’re experiencing a squealing or rattling sound from the engine, one of our professional mechanics can diagnose and repair the problem.
