1. Abnormal noise from the car body
Abnormal noise from the car body is the most common. It is usually caused by insufficient rigidity of the car body or long-term intense driving. walking on bumpy roads will cause slight deformation of the car body steel frame, the most direct impact is abnormal impact or friction between the door and the car, or abnormal friction in some welding parts or of screws, which may also cause abnormal noise. ; and some cars have more wind noise, which is different from the shape-related car to a certain extent.
Solution:
These abnormal noises aren't terrible and won't have a big impact on the vehicle's overall performance, but they are annoying to deal with and difficult to cure. can only be caused by abnormal conditions. Add stampsrubber or sponges to areas of friction or impact.
2. Abnormal noises in the car
Abnormal noises in the car are the most common, and there are many places where abnormal noises occur, such as improperly installed decorative panels and the glove box. of driver Looseness, impact of seat belt buckle, etc.
Solution:
Reset it automatically or fill it with soft objects.
3. Abnormal brake noise
If there is a “squealing” sound when applying the brakes, it is most likely caused by excessive wear of the brake pads, resulting in excessive gaps. Of course, improper use or deformation of the brake disc material, as well as unqualified hardness, porosity, friction characteristics and compression characteristics of the brake pads may cause abnormal noise.
Generally speaking, the durationThe life of the front brake pads is 30,000 kilometers and that of the rear brake pads is 120,000 kilometers.
Solution:
Abnormal brake noise can usually be resolved by replacing the brake pads. If the brake disc is damaged, it must also be replaced. When replacing, be careful. Model and other issues, otherwise the disparity will always persist. There will be an abnormal noise.
4. Abnormal suspension noise
The suspension system continues to operate while driving and the rubber bushings between the shock absorbers and each connecting rod inevitably wear out as the bushing ages or. falls, there will be abnormal metal impact sounds. If the shock absorber is broken, there will be a "dong dong" or "click" sound on bumpy roads.
Solution:
Generally, abnormal suspension noise cannot be solved by yourself. You must go to a workshoprepair or a 4S workshop for a specialized master to replace the parts. If this occurs, it must be resolved as quickly as possible. It is best to strengthen inspections during daily maintenance to avoid the occurrence of abnormal noises.
5. Abnormal noise from tires
Abnormal noise caused by tires is generally tire noise. The noise generated will also depend on the car's driving speed, tire type, tire pressure and road surface. conditions, etc. Factors produce various noises of different strengths and weaknesses. When there is a faint “pop” noise, it is mainly due to tire tread deformation, bagging, heavy wear, or insufficient air pressure. If there is a “clicking” sound, the tread may be mixed with small stones or nails. .
If the wheels make a loud noisemetal friction while driving, it is likely that the shock absorbers and bearings will be damaged. Car owners should be careful when encountering these problems, even just driving nails can be dangerous.
Solution:
It was found that the tread was mixed with small stones.Wait, you can clean it yourself. Other issues should be brought to the attention of the car owner and requested to be handled by professionals.
6. Abnormal noise from steering wheel
Abnormal noise will be detected when the steering wheel is turned left and right. When an abnormal noise occurs halfway, it may be. essentially considered an abnormal noise coming from the steering gear. If it is difficult to determine the source of the abnormal noise after turning the steering wheel, the most common answer obtained by going to a store4S for a test is the friction of the steering wheel rubber sleeve. the ball joint of the steering rod.
In addition, abnormal noises may also be caused by oil leakage from the steering gear cover, insufficient tightening of the power assist belt, or aging.
Solution:
The tie rod ball joint is getting old and the steering gear has problems and needs to be replaced in time.
7. Abnormal noises in the engine compartment
The situation of abnormal noises in the engine compartment is complicated and requires careful investigation.
If the belt squeaks or whistles, it is usually due to belt slippage. If it is an air leak noise, it may be caused by a blockage or breakage in the exhaust system or vacuum tubes; If there is friction and abnormal noise from external metal parts when the engine is running, this can usuallybe caused by damage to the generator, water pump, etc.
Solution:
Find a professional to repair it as soon as possible
8 Abnormal noise in the gearbox
If the gearbox gear is broken. is used while the car is moving If there is a "rustling" sound inside and a whistling sound when changing gears, this may be caused by worn gearbox bearings or gears or by rolling points.
If the gearbox makes an abnormal noise when accelerating and changing gears, the gearbox oil may contain metal powder, indicating excessive gear wear. the brake belt of the gearbox, clutch and other components.
Solution:
The gearbox is precision equipment, so no matter what abnormal noise occurs, it should be repaired in time.
What does the light on the board mean?dashboard of the Toyota Land Cruiser?
Open the lid and there is a small black box on the right.
After checking the official website of Prado car, we learned that when the relay is opened, there is a small black box on the right side. Open the lid of the black box and there will be. a corresponding position on the cover.
The Prado is the latest model in the Toyota Land Cruiser series, with good power performance and Euro III emissions.
Why does the engine of the Prado 10 model make a whistling sound?
1. The combustible mixture is too rich. The remaining unburned parts will accumulate on the spark plug electrode and be carbonized, causing the spark plug to flash abnormally until it is damaged by carbonization. The reasons why the fuel mixture is too rich are usually that the oil levelcarburetor is too high, the carburetor's main air volume hole is clogged, and the air filter element is seriously clogged. Additionally, the carburetor choke is blocked and cannot be fully opened, or the enrichment valve is not working properly, which is also the reason why the fuel mixture is too rich.
2. Engine oil leak. During engine operation, if blue or black smoke comes from the exhaust pipe, this indicates that excess engine oil has entered the cylinder. This will cause a large amount of carbon deposits to be produced on the spark plug electrode, or will be moistened by engine oil and prevent it from sparking. This phenomenon is commonly referred to as engine oil channeling. For two-stroke engines, check if the quantity of. the oil in the oil pump is too large and if the rod sleeve seal and plug soundt. Check if the check valve is defective; For four-stroke engines, check the piston rings on the piston, especially the oil rings, for wear. Then remove the intake valve and check for carbon and wet grease deposits on its head and back. If the valve and valve guide are severely worn, the valve guide seal is hardened, or the seal lip is excessively worn, the mounting gap will be too large and the effect of The seal will be lost. Both of these abnormal situations will eventually cause oil in the valve rocker arm chamber to be drawn into the cylinder along the valve stem during intake air summing, causing oil combustion. In this regard, the valve guide, oil seal or valve must be replaced respectively depending on their wear.
3. In the ignition system, the magneto is demagnetized, the conwire connections inside the ignition coil and electronic ignition, the output end of the generator and the input end of the ignition coil are loosened and the advance time to the ignition is incorrect. If it is not properly timed, it will affect the ignition performance, and poor ignition performance will directly cause carbon deposits on the spark plug electrode.
4. Pay attention that the spark plug model and calorific value comply with the instructions for use. If the selected calorific value is one or two ratios lower than that specified in the instruction manual, the temperature of the spark plug will rise very high and the heat cannot be dissipated in time, causing abnormal combustion and possibly melting of the spark plug electrode. and cause premature damage. When the spark plug itself est installed and used, some faults are not easy to detect and also affect the ignition performance. For example, if the spark plug is poorly sealed or the spark plug is solid, it should be adjusted or replaced in time. 5. If the crankcase oil is overfilled and the breather pipe is blocked, the pressure in the crankcase will increase and the crankcase will not be balanced.
The reason why the Prado Model 10 engine generator makes a whistling sound is because there is a gap in the bearing. You can remove the belt and listen again. If there is noise, it is the sound inside the engine. If there is no sound, it is the sound produced by the accessories. For specific abnormal noises, it is recommended to do so. you check it at a repair shop.
Prado Features
Prado is the latest model in Toyota Land Cruiser series, with good performancepower and emission standards compliant with Euro III. The advanced motor provides high power output and torque, coupled with the highly rigid frame and reinforced suspension system, the most rugged journey will become comfortable and smooth.
Although Prado was born 14 years later than Pajero, it is a slightly famous figure in the world of off-road vehicles. Of course, this must largely be attributed to the reputation of its older brother Land Cruiser. You know, Land Cruiser is one of the three oldest off-road vehicle brands in the world. The first and second are Jeep and Land Rover respectively.
As early as 1951, Toyota used Jeep technology to create the BJ series of four-wheel-drive, versatile lightweight off-road vehicles. Three years later, the car was officially renamed the Land Cruiser. After half a century of continuing education,.
