Engine noises that should not be ignored!!!

We've all been there.  Our kids are being too loud, making the best of the drive home in traffic, road trip fun, or when our vehicle is making strange noise, we crank up that stereo and let the music take over.  I'm down for all of these except for if your vehicle engine is making unusual noises.  This is one thing you shouldn't drown out.  But how can you decipher between an unusual noise and a typical engine sound.  Let me specify some of the unusual noises to listen out for:

Squealing: If you hear squealing come from the engine compartment this could mean that a belt or pulley is loose or worn out.  The belts drive several components of the engine along with the pulleys.  If either of these has gone bad it could leave you stranded on the side of the road.  You will hear this type of squealing while your engine is turned on and is at idle or even while driving.  If you hear squealing while braking, this indicates that the pads have started to get close to worn out.  If you ignore this indicator, your brake components will start to contact each other, which could cause expensive damage.

Hissing:  Hissing sounds coming from your engine could indicate a problem with the hoses that connect to your radiator.  Over time hoses become dry and can crack.  If you hear this sound while driving take a glance at your temperature gauge, your vehicle could be overheating (losing coolant).  Steam flowing out from under the hood is an even more serious indicator.  If this is happening, pull over, turn the vehicle off and DO NOT open the hood.  Let the vehicle sit, call a tow truck and your local mechanic.  

Ticking:  Most of the time a ticking noise coming from the engine will be an indication of low oil level.  Your engine oil is the lubricant for all the internal parts of your engine.  If it is low or the pressure is low then the internal parts may be rubbing metal to metal, thus creating the ticking sound.  First thing for you to do would be to turn the vehicle off and let it cool for a little while, then check the engine oil level.  If it is low, add as much oil as necessary.  If the ticking sound does not go away, this could indicate low oil pressure which is a bit more complicated of an issue and should be tackled by an automotive mechanic. 

Knocking or pinging: A knocking or pinging noise indicates that there are worn out parts in the engine.  There are several components that could be worn out, so getting your vehicle to your mechanic ASAP is highly advised to prevent further damage to both your engine and your wallet.

Clicking:  There are many components of your engine that make clicking noises: timing chains, rocker arms, and the camshaft.  The noise from these parts are usually pretty quiet and you wouldn't notice them unless you were really listening out for them.  When the clicking sound from them becomes more noticeable or louder is when you should start to be concerned.
