What That Weird Noise Under Your Hood Could Be

Inland Sales & Service • 3 June 2025

Hearing a strange noise from under your hood is never a good sign. While it might be tempting to turn up the radio and ignore it, these sounds are often your car’s way of asking for help. Catching issues early can save you from a bigger, costlier problem down the road. Here’s a breakdown of what those odd noises might mean and why they matter. When you need under-the-hood auto repair in Airway Heights, WA, visit the team at Inland Sales & Service.


Squealing or Screeching


A high-pitched squeal, especially when you start the engine or accelerate, often points to a worn serpentine belt. This belt powers components like your alternator, power steering pump, and air conditioning compressor. If it breaks, you could find yourself stranded.


Clicking or Ticking


A rhythmic clicking sound might be coming from low oil levels or problems with the valve train. It’s a warning sign that your engine isn’t getting the lubrication it needs. Check your oil level immediately; running an engine low on oil can lead to major damage.


Knocking


That knocking sound from deep within your engine? It’s usually bad news. Engine knocking often points to detonation problems, worn bearings, or issues with the combustion process. If ignored, it can eventually destroy your engine.


Hissing


A hissing noise under the hood may indicate a vacuum leak or a problem with the cooling system. It could be as simple as a loose hose, or it might signal that your engine is overheating; something you’ll want to fix before it causes more serious trouble.


Grinding


Grinding sounds often involve your brakes or starter motor. If it happens when you brake, your pads might be worn down to the metal. If it grinds when starting the car, your starter or flywheel could be to blame.
