Noise in the car engine: 8 problems it can indicate
Generally, when you hear a strange noise in the car's engine , it is not usually a sign of a good thing. These sounds can appear when starting the vehicle, releasing the clutch pedal or even when passing over speed bumps or holes and should not be ignored.
Tension of the timing belt
A very common cause of engine noise is the loss of tension on the toothed belt. Its basic function is to keep the crankshaft and valve timing in sync, and when a belt tensioner locks or breaks, the head and other engine parts can be damaged - and this type of repair is always expensive.
Try to make a visual inspection on this component at least every 15 thousand km, paying attention to the occurrence of cracks or cracks in the belt - which can be signs of dryness of the rubber. Another factor to consider is that cars that travel in places with a lot of dust or mud can have accelerated wear, since dirt is impregnated in the system.
Water pump
The water pump is a component that acts in the cooling system of internal combustion engines, and is responsible for cooling the car's engine - in order to prevent it from overheating. Usually the noise originated by this part appears accompanied by a leak, and its repair depends only on the replacement of the component.
Head problem or bearings
The noise that appears in the engine when starting cold (after the car has stopped for a night, for example) usually suggests problems in the head or in the bearings. In this type of situation, it is common to use the expression “the engine is hitting the start”.
In this case, it is important to immediately seek a qualified and reliable mechanic to carry out the correct diagnosis of the problem.
Poorly adjusted clutches
Clutch problems usually manifest themselves through the emission of noise when releasing the pedal when changing gears. This can mean wear on its shaft or bearing, requiring replacement of these parts. Take the opportunity to also change disc and plateau in this situation, as the labor cost for this service is not cheap.
Lack of water in the radiator
This is another problem that can result in the engine heating up - which can lead to its casting. To avoid it, just check the water level regularly and pay attention to the thermometer on the panel. Also clean the system: remove the radiator and the water tank from the place and wash them with the specific products for that purpose.
Cast motor
It sure is the worst problem you can have. Casting the engine means that the most important part of your vehicle is completely inoperative and, in most cases, it is necessary to make a complete replacement - which is one of the biggest expenses you can have when carrying out a repair.

A strong indication that the engine is fused is when trying to start and it does not work, it just makes noises of parts hitting each other. If you are not able to connect, do not insist: this can cause the wires to overheat and cause them to start smoking.
Broken engine support
Depending on the model of your car, the engine may have the support of three or four cushions - a kind of “cushion” that has the function of accommodating it and absorbing its vibrations. Passing through holes or speed bumps at high speed can often break these supports, which, when damaged, emit a serious noise.
Power steering pump
Engine noise caused by the power steering pump can vary in intensity when steering the steering wheel and usually looks similar to high-pitched whistles.
Some pump models allow the exchange of internal parts, but in others, this component is sealed and it is not possible to carry out any type of repair, requiring replacement.
Sometimes, simple functions can prove to be quite challenging - being a driver, for example. We should always try to inform ourselves as much as possible about the operation of the car we drive to avoid being caught off guard.
