David quickly diagnosed my real problem. I was told by an auto repair shop that my alternator was bad. the problem was my tension pulley was making the noise. This was really great news, because my repairs were going to be less expensive. I am happy with David's diagnoses and look forward to having David perform the necessary repairs on my Honda.

Quick and quality service! He arrived early, diagnosed my car issue, AND fixed it on the spot. Really appreciated going the extra step so I didn't need to make a follow up appointment; and taking the time to show me what was wrong and how he was going to fix it.

Addison was fantastic! Very knowledgeable. Would love to do business with Addison again. He went over my vehicle with a fine tooth comb and gave me estimates on everything that he recommended be done. There was more issues than I thought and he didn't stop until he found the noises.

Loud squealing or rattling is coming from engine Inspection Service

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.

How this system works:

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).

Common reasons for this to happen:

  • Stretched Belt: Belts are made of rubber and while they’re designed for high-performance and high-heat situations, they do wear. First, they’ll begin to stretch. If you’re hearing a squealing sound from under the hood, chances are very good that it’s a belt slipping on the pulley.

  • Failing Pulley Bearings: When the bearings in a pulley begin to fail, it can produce both rattling and squealing sounds. This can easily be confused for other problems, including a stretched belt, loose exhaust components and more.

  • Loose Exhaust: Your exhaust system runs from the exhaust manifold on the engine, underneath the engine, and then under the car to the muffler. If your exhaust is damaged or a support has come loose, it’s possible that it could make a rattling sound during operation (particularly noticeable while idling and when accelerating).

  • Worn Brake Pads: If you’re hearing a squealing sound from the front of the car, there’s also the possibility that the brakes are worn out. Disc brake pads are equipped with a “squealer”, which is nothing more than a small piece of metal designed to contact the rotor when the pads are close to the end of their life. This creates a warning squeal, telling drivers it’s time to replace their pads.

What to expect:

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.

How it's done:

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.

How important is this service?

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.
