Why does my serpentine belt make a whining noise?

This may be related to a variety of things that are driven by the serpentine belt that may correlate to the acceleration, however the most common noises resembling a whining sound are a failing alternator or a power steering pump… Hey there.

Can a belt be removed from a car alternator?

The alternator actually pivots around the lower bolt, so you can remove the belt. The other bolt will be in a slot not a round hole, and the position of the bolt in the slot adjusts the belt tension. You didn’t tension the belt enough when you refitted the alternator.

Why do serpentine belts have to be replaced?

Thanks to improvements in rubber technology, serpentine belts last much longer than they did back in the day. Most serpentine belts generally last between 50,000 and 100,000 miles. Eventually, your car’s serpentine belt will wear down from continuous exposure to heat and friction and will need to be replaced.

What is the cost of a serpentine belt replacement?

The costs of replacing a serpentine belt greatly depends on the make/model of the car you drive, the mechanic you hire and where you live. For just the parts, most serpentine belts retail for $15 to $45, but if you needed to hire a mechanic to replace it, then the costs could increase…

How do I put on serpentine belt?

Snap a long-handled ratchet or a serpentine belt tool into the square 1/2-in.-drive or 3/8-in.-drive opening. Or use a socket on the hex-shaped protruding nut. Slowly rotate the tensioner arm as far as it will turn. Then release the tension.

Can a loose serpentine belt cause an alternator to whine?

If the belt is too loose to maintain grip on the alternator pulley, you may experience a similar symptom as a snapped belt. If you start to notice a whine from the engine that changes with engine speed, you may want to have the tension of the serpentine belt double checked.

How did the serpentine belt get its name?

The serpentine belt is aptly named for the way it snakes around the pulleys inside the engine bay. This long, winding rubber belt powers many of the important systems of your vehicle by transferring power from the engine’s crankshaft to the accessory pulleys.

How can I increase the tension on my serpentine belt?

Increase the tension on the belt. If your vehicle does not have an auto tensioner, insert a pry bar or piece of wood between the alternator and the engine. Run the belt over the alternator pulley, then use the bar to pry the alternator away from the engine and increase the tension on the belt.

What can shorten the life of a car battery?

Missing or loose hold downs can significantly shorten battery life. While less common than the factors above, a malfunctioning charging system will also reduce battery life. Persistent under- or over-charging accelerates battery aging.

How does the serpentine belt work on a car?

As your engine runs, the spinning motion of the crankshaft is transferred to each of the accessory pulleys via the serpentine belt. If your vehicle is supercharged, the serpentine belt also powers the supercharger. Older engines have v-belts instead of serpentine belts.

What to do if your car squeals after replacing the serpentine belt?

Drivers should have a technician check both parts and replace what is necessary to correct the squeal. The serpentine belt provides power to the vehicle’s water pump, air conditioner, power steering and alternator. The tensioner is a spring-loaded device that holds the belt tightly against the pulleys of each of these accessories.

How long does it take to replace serpentine belt?

Once on, make sure the belt is completely on and centered on each pulley very carefully. Then, start the engine.

Why does my serpentine belt make a squealing noise?

My car has 134000 miles. Noise of that type is due to a failed or failing bearing in one of the pulleys or accessories (e.g., alternator, water pump, A/C compressor) that is driven by the serpentine belt, the belt is not properly tensioned, or the rotating pulleys driven by the belt are not all in the same plane.

Is the timing belt the same as the serpentine belt?

No, a timing belt is not the same thing as a serpentine belt. A timing belt is used to synchronize the moving parts of your crankshaft and camshaft. Your serpentine belt as we previously discussed is used to drive the accessories of your car.

When to replace a broken serpentine engine belt?

How is the tension set on a serpentine belt?

Depending on the application, your serpentine belt will either have tension placed on it using a movable bracket or an auto tensioner pulley. This pulley uses an internal spring to apply consistent pressure to the belt at all times. If your vehicle does not have a tensioner pulley, the alternator bracket is likely how tension is set on the belt.

What causes a belt to start to shred?

TOM Another possibility is a bad idler pulley or tensioner pulley. Those are sort of “dummy” pulleys that are used to alter the direction of the belt. If a bearing goes bad on one of those pulleys, it tends to tilt, and that could cause the belt to shred.

What happens if a serpentine belt goes bad?

The serpentine belt in most modern vehicles transfers power from the crank pulley to the various accessories mounted on the engine. A worn or damaged serpentine belt can fail to adequately transfer the power, leaving your alternator, power steering, and air conditioning failing to function.

What causes a serpentine belt to come off?

Belt coming off: Pulley misalignment, belt misalignment on pulley, defective tensioner, or bearing wear in tensioner, idler or driven accessories Belt noise can be hard to isolate, as the sound may seem to be coming from an accessory drive, such as the alternator or air conditioning compressor.

How do you replace a serpentine belt pulley?

Using the breaker bar or serpentine belt tool, move the tensioner arm against the spring as far as it will move, to its stop. The tensioner arm should move smoothly throughout its range of travel, with firm spring pressure and without binding. Most tensioner pulleys can be replaced independently of the tensioner itself.
