Warning Signs that Your Engine Will Fail

It’s inevitable that as your vehicle ages, you will experience sudden vehicle failure, especially if it’s constantly used. That said, it can be hard to pinpoint exactly where the issue is coming from. It could stem from your shocks or struts, your electrical system, your brakes or heating, or even the cooling system of your vehicle. It’s apparent that as the performance of your engine starts to wear off, it will exhibit certain warning signs that you should take note of. Before your vehicle experiences total engine failure, it’s best to learn about these warning signs in order to get any issues resolved quickly and with a minimum amount of inconvenience on your part.

Here are six warning signs of diminishing engine performance that you should be wary of:

Engine Light Activation

The first thing to rely on is the activated check engine light. After all, it is a powerful tool designed to pinpoint potential engine trouble. It will typically light up when it detects engine issues stemming from a loss of power. In most instances, a flashing light indicates a potentially serious defect in one of your vehicle’s systems. The best thing to do is to stop driving immediately and call for a towing service to help you out. You will need to get an engine diagnostic service to determine the issue, so you will know how to address it.

Gas Mileage Drop-off

Another thing to be wary of is the gas mileage drop-off. If a full tank of gas doesn’t last nearly as long as it used to, chances are there is an issue in the compression stroke of your engine. In such an instance, you may resort to two things to clear up the issue: use a fuel cleaner or have a fuel system service performed to correct the problem.

Power Loss

The most apparent engine issue is the loss of power. This could stem from a hiccup in one of four strokes in the combustion process of your vehicle. We know that a car engine makes use of a four-stroke combustion cycle to convert gasoline into the power a vehicle needs to move. The combustion cycle includes intake stroke, compression stroke, combustion stroke, and exhaust stroke. Chances are the power loss may have to do with one of these four strokes.

Engine Noises

It’s important, as well, not to take engine noises for granted. Such noises are an indication that the combustion flow isn’t working as it should. If you hear knocking, backfiring, hissing, spitting or popping sounds, it’s best to contact an auto-repair shop and have your engine checked as soon as possible.

Noxious Exhaust Odor

Another thing to be wary of is an unusual odour coming from the exhaust. It is possible that this odour is an indication that the exhaust stroke of your internal combustion engine is starting to fail. That said, your vehicle needs attention from a professional, so contact one as soon as you can!

Engine Stalling

We know that engines stall for a reason. If the clutch pedal and gas pedal are not engaged at the right speed, your car will most likely shudder to a stop, which means you’ll need to restart it. Now, if your vehicle’s engine stalls frequently, chances are there is something wrong with its engine components. It may have to do with the intake stroke, or it may not be receiving the right spark, air or fuel mixture. Engine stalling can lead to greater issues, so it’s best to get your car tuned up. Make sure that you have it checked out by a professional immediately.
