5 Engine Noises That Require Immediate Attention

Our certified technicians have provided some details below, so read on to learn more!

Hissing or Whistling Noises

If you hear any hissing sounds or whistling, this may mean that your engine is overheating. A plugged exhaust system or catalytic converter may be to blame, or there may be engine fluids leaking into the bay. This can not only cause damage but is a serious fire risk, so do not delay service! 

Grinding Noises

A grinding sound originating from your engine could indicate a number of issues, including the following:

• Worn out bearings no longer efficiently reducing friction
• Faulty alternator struggling to turn the engine’s belt 
• Damaged or worn out timing belt 
• Insufficient lubricant due to low oil levels  
• Worn out brake pads (if heard while braking)
• Worn out clutch (if heard when shifting)

Knocking Noises

Engine knocking may feel like a light tapping that gradually gets louder, and may point to several concerning issues that should be addressed immediately to prevent engine damage.

• Insufficient lubricant due to low oil levels 
• Worn-out engine bearing 
• Damaged spark plug or old air filter causing ignition problems

Squealing Noises

A squealing noise is often the result of a loose or worn out belt, like the serpentine belt that controls components like the water pump or alternator. If you hear squealing when you brake, it could mean that dirt has built up on the brake rotors, drums, or pads.

Rattling Noises

A rattling or clicking sound is often caused by loose or damaged components, often the heat shield or exhaust system parts. If heard when accelerating, rattling could indicate a loose timing belt, chain tensioner, cracked flywheel, or a broken flexplate. Rattling can also involve hydraulic valve lifters that do not properly open and close the engine’s intake and exhaust valves.
