In order to avoid the curse of vehicle engine failure, we have compiled a list of the most common factors that are responsible for car engine failures. Do not cast a glance if you really want to get stuck in the middle of nowhere unexpectedly. However, if you seriously want to take care of car engine then what are you waiting for? Scroll down and save yourself from any discomfort in the future. These causes have been outlined by replacement car engine experts so its worth paying attention.

1. Overheating

Not only these but also a bad thermostat, a defective cooling fan, or a futile water pump. Make sure that cooling system is working fine and in accordance with the vehicle maker’s guidelines for coolant flushes. This will help you a great deal in avoiding the chances of engine failure.


2. Inappropriate Lubrication

Among the most common causes of engine failures, there is also a spot for improper lubrication or the low levels of engine oil than recommended.The low level of engine oil can be the outcome of different issues such as a defective oil pump, wear and tear due to high mileage or gunky oil. In order to avoid this issue, ensure regular checks on the oil levels and that there is no leakage.

3. Detonation

Detonation is the outcome of inappropriate combustion in the engine that generates a large amount of pressure and heat in the combustion chamber. According to the auto experts, the reason behind denotation can be the loss of the exhaust gas recirculation system.

Moreover, other issues such as bad fuel, improper ignition timing, off beam spark plug gaps and raised engine operating temperature can also cause denotation. If you find any of these signals by your vehicle, get it checked from some expert mechanic in time.

4. Sinking the Car

Well, not literally of course. Drowning your car means driving through heavy rain or making it pass through deep standing water along the road. Some drivers take it as fun but less do they realize that this can potentially cause severe harm to your car engine, especially if it has a modified air intake.

In such a case, if water flows through the intake manifold, the result can be disastrous for your vehicle’s engine. Water ends up twisting the piston rods thereby damaging your engine and leading it to failure.

5. Oil Leaks

Those who are of the view that one must keep getting the car inspected from the mechanics regularly, are very right. There are many things you cannot judge yourself and one of those things is oil leaks. It is important to keep it in check if you do not want your engine to stall. Some of the causes of oil leaks are dilapidated rubber engine mounts, deteriorated steering components or suspension bushings in the engine.

Oil leaks can lead to engine failure in such a way that the leaks will render your car’s engine low on oil levels which will increase the friction between the parts of the engine. This will increase the temperature of the engine and the engine components will be mutilated badly and its fate will be a premature failure.

6. Ignoring the Engine Oil Light

All the cars come with warning lights unless you manufacture your own car. Jokes apart, warning lights are basically the indicators about any problems and issue your car might be facing.

The engine oil light is one thing you must keep casting a glance at, after short intervals. When you notice that engine oil light is on, you must realize that there is some sort of problem which needs fixing. This light can also be an indicator that it is time to replace the catalytic converter or oxygen sensor. However, any carelessness in this matter can lead your vehicle engine to failure.

7. Paying No Attention to Cooling System

If you do not remember the last time you flushed your vehicle’s engine coolant then the engine is at a high risk of failing. The auto experts are of the view that after every 30,000 miles, the engine coolant must be flushed.

This varies vehicle to vehicle but it usually takes 2 to 3 years on average to hit that much distance. Although it is a too long time duration to get worried, yet waiting until the coolant system gets deteriorated would not be the best strategy. Engine overheating is a symptom of deteriorated coolant.

8. Wrong Fuelling

Wrong fuelling means the act of putting wrong fuel in the car fuel tank. It usually accounts for filling diesel in petrol tank or petrol in diesel tank. It is quite a common mistake and each year thousands of drivers get snared in this catch-22 situation.

Even though it seems an innocent mistake, yet the results can be disastrous. No matter if you end up putting diesel in petrol vehicle or petrol in diesel vehicle, both can lead you to a very sorry state of affairs. The type of engine failure in this case mostly requires the engine to be replaced.
