What Causes the Abnormal Noise When Braking?

ABS's working process is actually a cyclic process of locking-releasing-locking-releasing, keeping the vehicle in a state of intermittent rolling at the critical lock point. When you press the brake pedal hard and trigger the ABS, a clunking sound will occur, which is normal. In this case, just press the brake pedal firmly to the end. Here is an introduction to the abnormal noise from the gear when braking: 1. If you hear a "clunk" sound between the transmission and the gear lever when stepping on the brake pedal, the main reason for the sound may be the electronic linkage between the brake system and the automatic transmission. When you step on the brake, the transmission solenoid valve will open and make a "clunk" sound. At this time, you need to press the gear lever lock button to shift gears. 2. If the clunking noise also occurs during light braking, or if the vehicle does not have an automatic transmission lock button at all, or if the noise is continuous or intermittent, then you need to pay attention. It is very likely that the brake system has malfunctioned or a connecting component in the chassis has become loose.

What is the normal tire pressure display for the Cadillac XT4?

Cadillac XT4's tire pressure display is normal between 2.3bar and 2.5bar. The tire pressure label on the vehicle indicates the original tire and the correct cold tire inflation pressure value. This label is located on the driver's side door frame at the center (B) pillar position. The recommended pressure is the minimum air pressure to support the vehicle's maximum load. Generally, in winter, the cold tire pressure will decrease, and it is recommended to maintain a cold tire pressure of around 2.5bar. The Cadillac XT4 is a compact luxury SUV under the Cadillac brand. In terms of body dimensions, its length, width, and height are 4600mm, 1881mm, and 1627mm respectively.

How many kilometers should the spark plugs of the new Jetta be replaced?

The spark plugs of the new Jetta should be replaced every 35,000 kilometers or 48 months. If the engine shakes, has difficulty starting, or experiences cylinder misfires due to specific reasons, the spark plugs need to be checked. In terms of power, the new Jetta offers two engine options: a 1.4L and a 1.5L. The 1.4L engine delivers a maximum power of 66kW (90PS) and a maximum torque of 132Nm, paired with a 5-speed manual transmission. The new Jetta is a car launched by FAW-Volkswagen Jetta, based on Volkswagen's family-style design language, featuring precise and dynamic lines that create a stylish and sporty appearance.

How many cylinders does the Bestune T77 engine have?

CA4GB15TD-30 is the engine model used in the Bestune T77, with a maximum horsepower of 169 hp, a maximum power of 124 KW, a maximum power speed of 5500 rpm, and a peak torque of 258 N.m. The Bestune T77 engine was independently developed by FAW Group, Bestune's parent company in China. For daily maintenance of the Bestune T77 engine, the following methods can be employed: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

Where is the air conditioning evaporator located in a car?

Automotive evaporators are generally installed under the dashboard on the passenger side. The car air conditioning evaporator is mounted inside the heater blower, which is a large plastic component containing air ducts, the evaporator, heater core, and other parts. Here is an introduction to automotive evaporators: 1. The car air conditioning evaporator is located inside the vehicle and adopts a direct air-cooled structure. It operates on the principle that low-temperature, low-pressure liquid refrigerant absorbs substantial heat during evaporation, thereby removing heat from the surrounding air to achieve cooling and dehumidification, while delivering cooled air into the cabin to lower the interior temperature. 2. The function of the evaporator is to allow high-temperature, high-pressure liquid refrigerant to enter through the atomization effect of the expansion valve. As the pressure decreases, the atomized refrigerant vaporizes into a gaseous state. During this phase change process, heat absorption occurs. Consequently, the surface temperature of the evaporator drops, and air passing over it becomes cooled.

What to Do If a Car Shock Absorber is Leaking Oil?

If oil leakage is detected, first tighten the oil cylinder cover nut. If the shock absorber continues to leak, it may be due to damaged or failed oil seals or sealing gaskets, and new seals should be replaced. If the leakage persists, pull out the shock absorber rod. If you feel resistance or uneven movement, further check whether the gap between the piston and the cylinder is too large, whether the shock absorber piston rod is bent, and whether there are scratches or marks on the piston rod surface or cylinder. Here are the symptoms of a damaged car shock absorber: 1. Drive the car on a road with poor conditions for 10 kilometers and then stop. Touch the shock absorber housing by hand. If it is not hot enough, it indicates there is no resistance inside the shock absorber, meaning it is not working. At this time, add an appropriate amount of lubricating oil and test again. If the housing becomes hot, it means the shock absorber is low on oil and should be refilled. Otherwise, the shock absorber is faulty. 2. Press the bumper firmly and then release it. If the car bounces no more than once or twice, the shock absorber is working well. 3. When the car is driven slowly and emergency braking is applied, if the car vibrates severely, it indicates a problem with the shock absorber. 4. Remove the shock absorber and stand it upright. Clamp the lower connecting ring in a bench vise and pull and press the shock absorber rod several times. There should be stable resistance during this process, with the resistance during upward recovery being greater than during downward pressing. If the resistance is unstable or absent, it may be due to insufficient oil inside the shock absorber or damaged valve components, which should be repaired or replaced.
