If you pay attention to your car whenever you are driving, you will be the first to notice when something is starting to go wrong.
There is a basic level of diagnosing that anyone can do with nothing more than their senses.
Being able to fix car problems takes years of experience, but you can use your senses to get an idea of what’s causing the problem.
Therefore, Your sense of sight, hearing, touch, and smell are the only tools you’ll need.
Staying ahead of problems by using your sense.
Also, The more you know about your vehicle, the more likely you’ll be able to head off repair problems.
Furthermore, You can detect many common vehicle problems by using your sense: eyeballing the area around your vehicle, listening for strange noises, sensing a difference in the way your vehicle handles, or even noticing unusual odors. However, if you can’t find anything it helps to look for a mechanic that can help you, especially one that has traders insurance so you know you both covered if something goes wrong.
“Pay attention to what you see”
While, Small stains or an occasional drop of fluid under your vehicle may not mean much. But wet spots deserve attention; check puddles immediately.
Hence, You can identify fluids by their color and consistency:
- Yellowish green, pastel blue or florescent orange colors indicate an overheated engine or an antifreeze leak caused by a bad hose, water pump or leaking radiator.
- A dark brown or black oily fluid means the engine is leaking oil. A bad seal or gasket could cause the leak.
- A red oily spot indicates a transmission or power-steering fluid leak.
- A puddle of clear water usually is no problem. It may be normal condensation from your vehicle’s air conditioner.
“Follow your nose”
Some problems are under your nose. You can detect them by their odor:
- The smell of burned toast — a light, sharp odor — often signals an electrical short and burning insulation. To be safe, try not to drive the vehicle until the problem is diagnosed.
- The smell of rotten eggs — a continuous burning-sulphur smell — usually indicates a problem in the catalytic converter or other emission control devices. Don’t delay diagnosis and repair.
- A thick acrid odor usually means burning oil. Look for sign of a leak.
- The smell of gasoline vapors after a failed start may mean you have flooded the engine. Wait a few minutes before trying again. Hence, If the odor persists, chances are there’s a leak in the fuel system — a potentially dangerous problem that needs immediate attention.
- Burning resin or an acrid chemical odor may signal overheated brakes or clutch. Check the parking brake. Stop. Allow the brakes to cool after repeated hard braking on mountain roads. Light smoke coming from a wheel indicates a stuck brake. The vehicle should be towed for repair.
- A sweet, steamy odor indicates a coolant leak. As a result, If the temperature gauge or warning light does not indicate overheating, drive carefully to the nearest service station, keeping an eye on your gauges. Consequently, If the odor is accompanied by a hot, metallic scent and steam from under the hood, your engine has overheated. Pull over immediately. Consequently, Continued driving could cause severe engine damage. The vehicle should be towed for repair.
“Don’t ignore your ears”
So, Squeaks, squeals, rattles, rumbles, and other sounds provide valuable clues about problems and maintenance needs. Here are some common noises and what they mean:
Squeal — A shrill, sharp noise, usually related to engine speed:
- Loose or worn power steering, fan or air conditioning belt.
Click — A slight sharp noise, related to either engine speed or vehicle speed:
- Loose wheel cover.
- Loose or bent fan blade.
- Stuck valve lifter or low engine oil.
Screech — A high-pitched, piercing metallic sound; usually occurs while the vehicle is in motion:
- Caused by brake wear indicators to let you know it’s time for maintenance.
Rumble — a low-pitched rhythmic sound.
- Defective exhaust pipe, converter or muffler.
- Worn universal joint or other drive-line component.
Ping — A high-pitched metallic tapping sound, related to engine speed:
- Usually caused by using gas with a lower octane rating than recommended. Check your owner’s manual for the proper octane rating. If the problem persists, engine ignition timing could be at fault.
Heavy Knock — A rhythmic pounding sound:
- Worn crankshaft or connecting rod bearings.
- Loose transmission torque converter.
“React to what you feel”
Because difficult handling, a rough ride, vibration and poor performance are symptoms you can feel. They almost always indicate a problem.
The following symptoms indicate engine trouble. Get a diagnosis and schedule the repair.
- Difficulty starting the engine.
- The “check engine” light on the instrument panel is lit.
- Rough idling or stalling.
- Poor acceleration.
- Poor fuel economy.
- Excessive oil use (more than one quart between changes).
- Engine continues running after the key is removed.
Car trouble doesn’t always mean major repairs. Finally, Here are some common causes of trouble and techniques to help you and your technician find and fix problems:
- Alternator — Loose wiring can make your alternator appear defective. Your technician should check for loose connections and perform an output test before replacing the alternator.
- Battery — Corroded or loose battery terminals can make the battery appear dead or defective. Your technician should clean the terminals and test battery function before replacing the battery.
- Starter — What appears to be a defective starter actually may be a dead battery or poor connection. Ask your technician to check all connections and test the battery before repairing the starter.
- Muffler — As a result a loud rumbling noise under your vehicle indicates a need for a new muffler or exhaust pipe.
- Tune-up — The old-fashioned “tune-up” may not be relevant to your vehicle. Fewer parts, other than belts, spark plugs, hoses and filters, need to be replaced on newer vehicles. Follow the recommendations in your owner’s manual.
