The life of your car's engine is also the life of your car. While modern-day cars are as complicated as any other machine, they are not invincible. This means that with time and regular wear, the car and the engine will start wearing out. When the vehicle starts suffering the consequences of age, it starts exhibiting certain signs that are not hard to miss. Here are the three crucial indicators that will show you that your engine needs repairs.
The Check Engine Light Comes On
One of the first indicators that your vehicle's engine is in trouble is the check engine light. The light is always located on the dashboard and could represent a wide array of engine problems. It is always advisable to see an auto-mechanic as soon as you realise that the check engine light is on because it is a clear indication that if you do not act, you will have to pay a lot in repair and even replacement costs.
Increased Exhaust Smoke
Another common indicator that your engine is in trouble is when the smoke coming out of your exhaust becomes thicker and in a variety of colours. For instance, thick black smoke is usually an indication that there is too much fuel getting into the combustion chamber. On the other hand, when the smoke is blue, it means that somehow, the engine oil is burning. White smoke usually indicates that there is some coolant leaking inside the vehicle's engine chamber. An auto mechanic will be in a position to assess the colour of the smoke and decide what part of the system is broken and needs to be fixed.
Rough Idle and Strange Noises
There is nothing that is more dangerous than a vehicle which stops or acts as if the engine will die in the middle of the road or other place. Some of the common causes of the rough idle include corroded spark plugs, problems with the fuel pump and fuel filters that are clogged with dirt. An even more worrisome problem with an engine that is in trouble is knocking noises coming from the engine. Knocking means that the engine bearings need to be replaced, and when this does not happen, your entire engine might need repair.
These are some of the common indications that you need to stop and get an engine repair. It is always advisable to get a professional to handle the maintenance and servicing of the engine as this will lengthen its usefulness.
