The noise of humming tires, whistling wipers, running engine are normal while driving. A good driver have ability to recognise normal and problematic noises. Diagnosing car noises which may create problems is a must have ability to avoid from bad situations.
Tapping, whistling, roaring, knocking, hissing are some of the bad car noises which require immediate attention. These indicate undeniably serious issues with the car. It is a life threat to all occupants and people around you.
Diagnosing Car Noises
Every issue create a unique noise. The basic approach is you have to reach the problem with its distinct noise.
Detecting Problems By Diagnosing Car Noises
You can identify a problem with below given noise-problem connection.
1. Knocking: Major Engine Issue
Knocking indicate issues inside the engine. There may be more than one problems. It is better to check it up with a machine. However you must not confuse it with a “ping” noise which is due to burning of low octance fuel.
2. Rattling: Loose Components
Car’s undercarriage consists of suspension, tires, rims, supports, bearings bush rms, silencer and several other. If one or some of these are loose you may hear a rattling sound.
3. Hissing: Leaks from Radiator
Hissing noise arise when radiator fluid enters into cylinders. It boil off and turns into steam. The damaged gasket is the instant culprit. There are many reasons why this gasket damages. Immediately book an appintment to save from further loss.

4. Grinding: Gearbox Problems
Grinding noise is a compromise on whole transmission arrangement. It may be due to a leak or low gear oil. The second option is defective car brakes if this odd noise produce while applying brakes. It happens due to worn brake pads as rotor discs are directly strike with metal.

5. Roaring: Rusty Silencer
Untill you have had add-on with your car silencer, roaring sound can’t be ignored. It indicates a rusty and worn-out muffler. Fuel emissions can breach car cabin and air become toxic. Instant car checkup is recommended.
6. Squealing: Slipping Fan Belt
Fan belt drives radiator fan, compressor, power steering in some cases. The slippage of fan belt produces squealing noise. Some lubes designed to control this slippage and noise are available. You may face this noise by applying brakes. Concentrate and differentiate the problem.
7. Whistling: Vaccum Leakage
Engine misfiring, bad fuel economy, poor consumption are major indicators which confirm whistling noises. It happens due to vaccum leakage in the air intake valves.

8. Tapping: Low Engine Oil Level
Tapping noise become more clear as you switch off the engine. It indicates low levels of engine oil. This will overheat the engine. You can monitor temperature gauge constantly. At once top up engine oil level and consult a mechanic why the car is lowering engine oil level.

9. Clunking: Worn Brake Pads or Various other Brake Issues
Clunking noise is an indication of defective brake pads, piston calipers and rotors. However if this noise produce only when you hit bumps, it points toward faulty suspension. Third case is a defective power steering if this irritating noise produce on turns.
