7 Common Car Engine Problems and Solutions
The engine of the car is one of the most important components of a car. It produces the required energy by compressing and igniting the fuel and the air.
If the engine does not function properly, it affects the overall working of the car.
You can take some advance steps and save time and money by taking action about these common car engine problems. But, for that you have to be observant about the symptoms or if your car is acting weird.
Engine Just Won’t Turn on
It is one of the most common issues in front of car owners. There are many reasons related to this issue.
If the clicking sound comes from the engine but the crack does not happen, it may indicate an issue with the car battery. However, if the crank happens but the car does not start, it means ignition might be facing some problems.
The possible reasons behind this simple term might be blocked fuel filters, corroded battery cables, faulty fuel pumps, batteries are discharged or the ignition switch is broken.
Overheating of Engine
Production of a large amount of energy can heat any machine, but there is a solution for this, the coolant system of the engine is there for lowering temperature.
But, if you are facing heating up of the engine again and again, then there must be some trouble going on with the coolant system.
Overheating of cars could be due to leakage in the cooling system, a broken thermostat, clogged hoses, loose plugs or radiator burning can be reasons behind the overheating. t is advised to solve this problem as soon as possible, as it will severely affect the functioning of the car.
Abnormally Loud Noises Heard:
If you heard any issue related to the voice of the engine or engine Is working louder than the usual, then it means there is some kind of serious issue you need to address.
The most common problem can be like missing due to dirt in the plug. There are some other problems which can make the engine sound louder are failed mufflers, gaskets or seals are worn off, leakage in the exhaust, the catalytic converter is falling or tailpipe is broken.
Oil Pump Indicator Turn On:
The engine oil pumps suck oil from the oil pan of the engine and transmit it to the filter and then to the bearing.
The problem of oil pumps can cause complete malfunctioning of the engine as well as for the parts to which the oil pump supplies oil.
This usually does not happen, but you need to look for signs if you feel strange changes in the operation of the car.
The first sign will be an indicator on your dashboard, but this is not an exact sign, because the indicator can be activated because of any other type of problem encountered with the car.
There are other signs to consider when there is a leak in the oil pump: low oil pressure, high engine operating temperature, and noise.
Oxygen Sensor is Faulty:
Inside the exhaust pipe oxygen sensor is placed to monitor the amount of oxygen in the exhaust.
Both high and low oxygen levels can be destructive for the engine, that’s why the sensor is placed to adjust the amount of fuel and oxygen entering the engine.
Some signs which indicate there is some kind of issues related to the working of the sensor are indicated on the dashboard or emission test failure or bad mileage.
Knocking the Engine:
Engine knocking is the phenomenon that results in the formation of an unwanted wave due to an overpressure caused by the self-ignition of the unburnt charge. This could damage the motor walls.
This occurs when two flames of self-igniting engines collide. This causes a considerable increase in the temperature and pressure of the unburnt parts.
The striking blow causes more trouble than any destruction. There may be some reasons as well as carbon deposits or low octane fuel.
Air Fuel Ratio is failing:
The air-fuel ratio sensor which controls the amount of air and fuel also known as the EFI system is part of modern vehicles and is located in the exhaust system before and after the catalytic converter. Some cars may have two or more fuel sensors.
They monitor the air/fuel ratio in the vehicle exhaust and send the engine computer fuel flow control to improve engine efficiency.
The presence of the fuel level sensor will ensure that the engine is working properly, but if it encounters any operational difficulties, the car starts to show the first signs, such as a decrease in fuel usage, a decrease in engine power, issue in the idle of the engine, sending the wrong signal to the engine will cause idle.
