The internal combustion engine of your vehicle comprises several metal components that move altogether when you run the engine. Hence, if one component gets damaged, the whole engine loses the balance that leads to a seized engine. Fortunately, a seized engine doesn’t mean it is damaged. If you spot signs and symptoms of a seized engine earlier, you may take your vehicle to the repair shop before your car stops during a journey.
That being said, we have compiled a list of symptoms of a seized engine that will help you in identifying the problem before it’s too late.
Common Symptoms of a Seized Car Engine
There are several signs that indicate your engine will or may soon seize. Below are some obvious symptoms of seized engine:
Engine Doesn’t Start
If your car’s engine is seized, then it might not start. However, your car battery will be able to operate the radio, heater, AC and other devices. Moreover, you may also hear clunking sounds when cranking the engine. The sound may be caused when the starter impacts the flywheel.
Check Engine Light is on
Your dashboard warning light will pop up when there is a problem with the car’s engine. It is one of the classic signs that tell you something is wrong with your vehicle. The red warning light should not be ignored, as it is triggered by the diagnostic reading.
Engine Noises
Wear on parts and components that are located under the hood of your car are responsible for emitting noises. These noises signal problems with the engine. If you spot a change in the exhaust pipe sound, it could also be a sign that you may have an engine blowout.
Before the engine seizes, you may also notice some strange noises such as light tapping or knocking. The sound will become louder with time as a piston connecting the rod hits the crankshaft.
Sudden Odour Inside the Vehicle
If there is a burning or smoke smell inside the vehicle, this is a sure sign that the engine is seizing. Even if you can’t identify it well, but you can sense a different odour inside the car, don’t wait and get your vehicle checked by the professionals.
Catalytic converter or external odours are quite different from what you feel when there is a problem with your engine.
Poor Acceleration
One of the common symptoms of a seized engine is not being able to drive a vehicle at a normal speed. With the seized engine, you can expect its performance to drop.
This means that every time you step on the pedal to accelerate your vehicle, it probably won’t go as fast as it normally would. You may not be able to increase the speed at all. It will eventually get to the point where your engine will stall completely.
Burnt Wires
The seized engine doesn’t burn the wires, it usually happens after the engine fails. The problem occurs as you start a vehicle and crank the engine. The wire overheats when the starter won’t be able to turn on the engine. You may also notice a burning smell which usually happens after the engine is being seized.
Physical Defect
Moreover, the car engine seizes when internal parts become loosened and lodged into other components such as piston connecting rods. These parts pierce through the engine block and break the piston rod.
How to Identify a Seized Engine
The best way to identify whether an engine is seized or not is to try to turn it over with a breaker bar. You need to first remove the drive belt of the engine and place the breaker bar in the crankshaft pulley bolt. Now, try to move the pulley bolt clockwise – to the direction of engine rotation. In case you failed to rotate the pulley completely, that means your car’s engine is seized.
