Common reasons for this to happen: Failing Water Pump Pulley: The most common cause of squealing or squeaking from the timing belt cover is the water pump pulley. If the bearings in the pulley are beginning to fail, they will make noise.

Does worn BMW belts make a screeching noise?
The most common serpentine belt problems include: Worn/Cracked Serpentine Belt – Serpentine belts have grooves which fit into grooves in the pulleys. Over time, the friction wears down these grooves, resulting in a loose fit. A worn belt can, therefore, begin to slip, which is one of the causes the squeal.
Why is my BMW engine whistling?

Can Low brake fluid cause squealing brakes?
Uneven brake pads: When the brake fluid gets low, the pedals cannot depress brake pads with the same amount of pressure. This causes uneven wear on the pads. In turn, you experience squeaking, squealing, and grinding when you apply the brakes. The vehicle may also rumble and vibrate when you use the brakes.
How do I stop my car from squealing?
Why is my car squealing when I drive slow?
Why does my car squeak when driving slowly? Brake pads and discs fitted poorly or worn will often cause a squeaking noise when you drive slowly. When you press the brake pedal, the brake calliper clamps around the pad, applying pressure to slow down the movement.
What does a worn idler pulley sound like?
Excessively Loose Idler Pulley The loose pulley can make chattering noises as it spins and the vibration can knock the serpentine belt off. A loose pulley can also mean its bearings are bad. If the pulley is excessively loose and there is a lot of play after wiggling it back and forth, it needs to be replaced.
How do you tell if a pulley is worn out?
Damaged pulley bearings can cause the pulley to freeze completely, preventing the belt from moving properly. You can check for this specific issue by taking your belt off the pulley in question and attempt to spin it by hand. If you find the pulley has any resistance, it will likely need to be replaced.
What are the symptoms of a failing idler pulley?
Without a belt, stalling and overheating of the engine become commonplace. For auditory cues, squealing noise from the engine belt can be a tell-tale sign. As the pulley wears, the engine belt may squeal as it rubs against the surface of the pulley. The issue will worsen with time.
Can you spray wd40 on a squeaky belt?

What does it mean when my turbo is whistling?
What causes turbo whistle? Turbo whistle is the sound of the compressor inside the turbocharger speeding up (also known as ‘spooling up’, which is why it kicks in at the boost threshold (when the turbo starts to kick in) as you accelerate up the rev range.
Why does my car make a whistling noise when I press the gas?
The sound you are hearing is air leaking across a damaged gasket or a warped sealing surface. With the throttle closed, or in deceleration mode, the manifold pressure is very low and if there is a leak anywhere in the induction system that should normally be sealed, you will hear the (very common) whistle.
How long can a squealing belt last?
The good news is a serpentine belt can last up to 50,000 miles or five years, with proper maintenance, before it needs replacing. Heat and friction of normal use slowly wear down the belt before it breaks.
