Why does the Engine of my Car Shake?

If your car engine is shaking, the problem could be caused by a number of different factors. Chances are that the engine's problem is with one of the parts which, among other functions, are designed to absorb the vibrations produced when the engine itself is running. While it may seem like the movement is being made by the engine, it is often actually coming from the axles of the car.

Is the harmonic balancer working?

The harmonic balancer or crankshaft damper might be the reason why your engine is shaking. In fact, this part is also known as a vibration damper because its purpose is to reduce torsional vibration, especially in diesel engines.

If the harmonic balancer gets damaged and stops working properly, one of the first symptoms that you will notice is the engine of your car shaking. See a mechanic as soon as possible to get the problem fixed.

Is the engine well mounted?

A faulty engine mount can be another cause of shaking. This part attaches the engine to the chassis, and one of its functions is to eliminate the vibrations generated by the engine running. Problems with the engine mount are rare both in transverse and longitudinal engines, but it can be damaged by aggressive driving. A mechanic should fix the fault.

Is it cold outside?

If the temperature is extremely cold, it's normal for the engine to vibrate more than usual. There's no need to worry if these vibrations disappear in normal weather conditions. The reason why many car engines shake in very cold weather is because the temperature is too low for the engine to run optimally.

Is there a problem with the spark plugs?

Spark plugs deliver the electric current to the combustion chamber of the engine from the ignition system in order; you need an electric spark to fire the fuel and air mixture and start the car.

Vibrations coming from your car engine can be a symptom of a problem with your vehicle's spark plugs. In this article we explain how to change the spark plugs yourself if you have the necessary tools and knowledge.

Are the axles damaged?

Sometimes it might seem that the engine of your car is shaking when in fact it is because of some damage to the car axles.

If your car has been in a crash - even if it's only a minor collision that left no outer signs of damage - the axles might have been slightly bent. It could also be that the CV joints (constant velocity joints) are worn out.

You should go to your mechanic to find out if any of these is the cause of the vibrations.

Similarly, you need to be sure that the tires are well attached and their alignment is balanced. A tire coming loose not only would explain why does it feel like the engine is shaking, but could also cause an accident.

You should also check the radiator fan and the fuel system, especially if the car shakes while still.
