There are usually two reasons for the crackling noise after starting the engine:
First, if the car has not moved for a long time, the engine oil will flow back to the oil pan and valve not having the seal and lubrication of the engine oil when starting the vehicle, causing a sizzling sound. This is normal.
Second, there is an abnormal noise from the belt when starting. In this case, it is necessary to check in time whether there is a problem with the belt.
Method
If there is any abnormal noise coming from the belt, check the assembly first. The abnormal noise may be caused by friction between the timing belt and the timing cover. You can loosen. the screws on the official case. Check with a half turn if the abnormal noise disappears.
Secondly, you can check the generator belt usage. The accessory belt mayproduces abnormal noise. The tightening of the timing transmission part is too tight. Remove the power generation and air conditioning power belts to rule out if the problem is with these two belts. There is a problem with the timing belt tensioner and usually needs to be replaced along with the timing belt.
What is happening with the crackling noise coming from the engine?
There are usually two reasons for the crackling noise after starting the engine engine:
First, if the car has not been moved for a long time, the oil will return to the oil pan. When the vehicle starts, the valves will lack seal and lubrication. oil, causing a sizzling sound. It's normal.
Second, there is an abnormal noise from the belt when starting. In this case, it is necessary to check in time whether there is a problem with the belt.
If there is an abnormal noise coming from the belt, check the assembly first. The abnormal noise may be caused by friction between the timing belt and the timing cover. You can loosen the official case screws by half. turn around to see if the abnormal noise disappears.
Secondly, you can check the generator belt usage. The accessory belt may produce an abnormal noise. The tightening of the timing transmission part is too tight. Remove the power generation and air conditioning power belts to rule out if the problem is with these two belts.
There is a problem with the timing belt tensioner and it usually needs to be replaced along with the timing belt. The noise may be caused by a problem with some of the motor bearings. The specific source of the sound must be carefully identified. If the specific cause does notcannot be found, it is recommended to go to a professional repair shop for inspection to determine the cause.

1. The motor makes a “grinding” sound. caused by steam or air coming from the engine. It's the same as if it came out from inside. Usually, after hearing this kind of noise, the engine will quickly lose power. Possible problem, engine overheats, check cooling system. The exhaust system is clogged, the suction pipe is leaking or broken.
2. When I stepped on the accelerator, I found that the acceleration was not obvious, there was a lack of power, and the engine made a hysterical noise. The times most likely to occur are when the engine is hot or cold, or when it is low on oil. The causes ofThese problems can be divided into air filter, spark plug, ignition wire, gasoline, fuel filter, carburetor, oil pump, etc. issue. Check if the air filter is dirty, if the spark plug is old and needs to be replaced, if the ignition coil is broken, and if the gasoline is not clean, such as water in the fuel line. 'oil. Also check the oil pump.
3. When accelerating, the engine will make a whirring sound, or it will also sound when decelerating. In short, the sound will change as the regime changes. The possible reason is lack of power steering oil, fill it up. The generator bearings could be damaged. Problems with the power steering pump and water pump will produce similar noises.

The reason why the car makes a crackling noise after startingstarting is that there is a problem with the engine. belt. The engine belt is the main belt of the car. The generator, air conditioning compressor, booster pump, axle pulley, tensioner pulley and crankshaft pulley are connected. The power source is the crankshaft pulley, which drives the rest of the components. work together. When the belt and pulley come into contact, small cracks appear on the surface. Finally, it must be replaced. The engine is the device that supplies power to the car. It constitutes the heart of the car and determines the power, economy, stability and environmental protection of the car. According to different energy sources, car engines can be divided into diesel and gasoline engines. engines, electric and hybrid vehicle engines.
