An engine is a vital part of a car and its proper functioning increases the lifespan of the vehicle. To keep the engine in full performance mode, it’s best to take your vehicle to service centres for regular maintenance. At these centres, the engine’s condition is well-examined, hence, you can save your car from severe potential damage. Therefore, knowing the symptoms of engine failure in cars will help you identify the problem at the earliest and address it timely.
Here are all the major signs of engine failure in cars that might need addressing.
SYMPTOMS OF ENGINE FAILURE IN CARS
Detailed here are some of the signs of car engine failure that you should not ignore:
SPOTTING OIL PATCHES
We often spot patches of oil on the ground beneath the car’s body when it is parked. Thinking it’s a harmless leak, we do not pay attention. On the contrary, oil patches are one of the early symptoms of engine failure in cars as it is the result of a gasket or an oil pan leak that damages the engine. The loss of lubrication increases friction in the combustion chamber, causing abrasion to the components. Therefore when you spot an oil patch, get your car checked immediately.
UNUSUAL SOUNDS FROM THE CAR
One of the common signs of car engine failure is the onset of weird sounds that most of us usually ignore. Weird sounds that we aren’t used to hearing when driving is the result of backfire or knocking, or even both. The term backfire is given when the air and fuel fail to combust completely, causing an influx of un-burnt residues to emerge from the exhaust more than usual. Similarly, when the air-fuel mixture occurs before time, it is called knocking. Thus if you are hearing irregular sounds coming from under the hood, it must be addressed immediately as it is damaging for the engine.
BLACK SMOKE COMING OUT
Cars that cough out a lot of smoke have been reconstructed into their modified versions that are now cleaner and less noisy. That said, if you spot a lot of smoke coming out from the exhaust pipe, or worse, if it is coloured, it is an alarming sign for the car. Black smoke indicates that the car is running on a rich air-fuel mixture, or that the fuel pump is exhausting itself out unnecessarily. In the case of blue smoke, the car’s engine is burning the engine oil with a leak around somewhere.
Smoke is a strong tell-tale sign of a problem with the vehicle, often smoke coming out of the engine is a result of faulty spark plugs. Therefore, if you see a higher than normal emergence of smoke, know that it is one of the strong symptoms of engine failure in cars.
VIBRATIONS WHILE DRIVING
You shouldn’t feel vibrations when driving on a smooth road. If you do, it’s likely an indicator of a bad engine. This occurs due to a faulty engine mount that has been worn out. Plus, misfiring in the engine is another reason for vibrations. Therefore, the next time your car vibrates even when idle, take immediate action.
TURNED ON CHECK ENGINE LIGHT
Check engine lights are there for a reason, and they are most likely to turn on when there’s a problem in your vehicle. If you see the engine check light blinking even when you restart the vehicle, you must not ignore or put off the visit to the mechanic for some other time. You can try resetting the check engine light, but if there is consistent blinking then most likely it is one of the symptoms of engine failure in cars.
ENGINE IS OVERHEATING
Overheating of any machine is a sign of a problem, which is why most modern cars are installed with an engine temperature gauge that indicates when the engine is operating at a high temperature.
If the needle stays in the middle, the temperature of the engine is ideal. When the needle begins to move towards the hotter range, you must understand that the cooling system of the vehicle is malfunctioning and has to be checked. If you continue driving with an overheated engine, the problem can worsen.
Besides, there could be various causes of engine overheating that you should keep track of in order to avoid any inconvenience.
LOW ENGINE OIL LEVEL
To ensure proper lubrication and smooth working of the engine, the engine oil level must not go down than the pre-set range. However, over time, the engine oil drops down due to various reasons and also could be one of the car engine failure symptoms. When it does, it means the engine is not getting proper lubrication and friction may increase wear and tear. Therefore, besides keeping a check on the oil engine level, identify causes of low engine oil pressure in the car. Moreover, monitor how soon the vehicle is losing the oil to catch probable leaks before time.
LOSS OF POWER
When the vehicle fails to reach the top speed of the car or experiences a loss of power while accelerating it is a sign of car engine failure. This can be due to the engine not getting enough fuel and air or because of the fuel filter being clogged. In the case of the vehicle installed with a turbocharger, loss of power can also be due to a problem in the car turbocharger.
ENGINE MISFIRING
Unusual sounds from the engine are an indicator of engine misfiring, stemming from a problem in the engine control units consisting of electrical wires in the vehicle. Engine misfiring can also be due to bigger problems including faulty spark plugs or low engine compression in extreme cases.
OILY SPARK PLUG
In cars operating on petrol, the engine oil can reach the spark plugs when there is a leak in the oil chamber. If you spot this scenario, get your car checked in the first place before the leaking chamber discharges all the oil and causes friction to worsen the case.
LOSS OF ENGINE BRAKING
Engine braking, the practice of releasing the accelerator and clutch, is a healthy exercise for the brake pads that result in prolonging their lifespan. On hilly roads, engine braking is used to control the speed during downhill driving. A loss in engine braking is a strong indicator of a faulty engine as it occurs due to insufficient compression in the chamber, giving way to other mechanical problems.
SUDDEN STALLING
The car starts then sputters and shuts off is another sign of engine failure in cars that suggests problems with the fuel filter and spark plugs. Other times, stalling of a car may not be related to engine errors, therefore it’s mandatory to get it checked as soon as possible.
The car engine is the heart of the vehicle. It may be designed to work tirelessly, but at the end of the day, a car is a machine that has to be checked for minor or major issues on a regular basis. In case your engine has completely worn out and cannot be fixed, it’s better that you replace your vehicle. If buying a new car is not within your budget, you may opt to buy a second-hand car in the UAE.
Knowing the signs of engine failure in cars can help detect the problem before it aggravates and leads to hefty repairs. Needless to say, you must make a practice of taking your car for a regular diagnosis to the mechanic to ensure proper maintenance for its prolonged life.
