How Often Should the Transmission Fluid in a Car Be Changed?

1 Answers

When a vehicle reaches a mileage of 40,000 kilometers or has been in use for 2 years, the transmission fluid needs to be changed. However, if the owner has purchased a Japanese model, the replacement interval can be slightly extended, and the fluid can be changed when the mileage reaches approximately 50,000 to 80,000 kilometers. Below is a related introduction about transmission fluid: The function of transmission fluid: It is an oil product that keeps the gear system clean, lubricates to extend the lifespan of the transmission device, and provides effective lubrication even under low-temperature conditions, reducing oil loss under harsh operating conditions. Characteristics of transmission fluid: Most transmission fluids can be used in automatic transmissions currently available on the market. In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicles will vary in torque, weight, speed, structure, etc. Therefore, the original manufacturer specifies its own dedicated transmission fluid. Different transmission fluids are one of the factors affecting the quality of gear shifting.

What are the symptoms of a broken lower control arm?

Symptoms of a broken lower control arm are as follows: 1. When the lower control arm is damaged, the vehicle's tires will exhibit abnormal wobbling during driving, leading to irregular tire wear, increased noise compared to normal conditions, and unstable driving. 2. Damage to the lower control arm causes dynamic stability imbalance in the vehicle, and severe cases of lower control arm breakage can result in loss of control over driving and steering. The replacement method for a broken lower control arm is as follows: 3. Lift the vehicle, remove both ends of the triangular arm, and select two iron sleeves of corresponding sizes to fit the rubber bushings. 4. Remove the screws, install new lower control arm rubber bushings coated with detergent for lubrication, and then reassemble in reverse order. 5. The replacement of the lower control arm rubber bushings should not be done carelessly. It requires professional adherence to parameter specifications, with a specific sequence of steps that must not be altered.

How many cylinders does the Jingyi X5 engine have?

Jingyi X5 is equipped with a 4-cylinder engine. The function of the engine is to convert the thermal energy of gasoline into mechanical energy by burning and expanding the gas in a sealed cylinder to push the piston to do work. Taking the 2019 Jingyi X5 as an example, it belongs to a compact SUV with a body size of 4515mm in length, 1812mm in width, 1725mm in height, and a wheelbase of 2720mm. The fuel tank capacity is 55 liters, and the curb weight is 1545kg. The 2019 Jingyi X5 features a MacPherson independent front suspension and a multi-link independent rear suspension. It is powered by a 1.5L turbocharged engine with a maximum horsepower of 150PS, a maximum power of 110kW, and a maximum torque of 200Nm, paired with an 8-speed continuously variable transmission.

What are the components of the crank-connecting rod mechanism?

The components of the crank-connecting rod mechanism include: the engine block group, the piston-connecting rod group, and the crankshaft-flywheel group. The function of the crank-connecting rod mechanism: to provide a combustion chamber, convert the expansion pressure of the gas after fuel combustion acting on the top of the piston into the rotational torque of the crankshaft, and continuously output power. The engine block group consists of the cylinder block, cylinder gasket, cylinder head, crankcase, cylinder liner, and oil pan. The piston-connecting rod group consists of the piston, piston rings, piston pin, and connecting rod. The crankshaft-flywheel group consists of the crankshaft, flywheel, torsional vibration damper, and balance shaft. The function of the crankshaft-flywheel group: to convert the gas force transmitted by the piston-connecting rod group into the rotational torque of the crankshaft for external output, driving the engine's valve train and other auxiliary devices to work.

Where is the secondary air valve located on the Passat?

The secondary air valve of the Passat is located inside the cover above the air filter box. The secondary air pump is positioned at the lower front part of the air filter box (closer to the front of the car), connected to the lower front of the air filter box via a plastic tube approximately 3 cm in diameter. Introduction to the secondary air system: The secondary air system is one of the external purification devices designed to reduce exhaust emissions. It is used for exhaust reprocessing during the engine warm-up phase. In this process, fresh air is directly blown into the exhaust manifold to heat the exhaust catalytic converter more quickly. The engine controls the secondary air pump through the secondary air pump relay. Function of the secondary air system: When the engine is cold, the system delivers air to the three-way catalytic converter. This allows the exhaust gases to react with the oxygen in the air for secondary combustion, thereby increasing the temperature of the three-way catalytic converter. This helps the three-way catalytic converter reach its operating temperature more quickly and enter its working state, reducing the emission of harmful substances in the exhaust and serving an environmental protection purpose.

What to Do About Foggy Car Headlights?

Solutions for foggy car headlights are as follows: 1. Turn on the headlight switch to use the heat generated by the headlights to evaporate the fog. 2. Park the car under direct sunlight for several hours to use the heat from the sun to evaporate the fog. 3. Open the dust cover at the back of the headlight and use a hairdryer to dry it. Extended Knowledge on Car Headlight Principles: 1. Whether it's a standard halogen headlight, xenon headlight, or LED headlight assembly, there is a vent rubber tube at the rear cover position. 2. When the headlight is turned on or during use, it generates a significant amount of heat. The vent tube's function is to expel this heat as much as possible to maintain the headlight's normal operating temperature and ensure stable performance. 3. Moisture in the air can enter the headlight through the vent tube and attach to the lens. As the moisture accumulates, droplets form and flow down the lens. 4. This phenomenon is mostly caused by significant temperature differences and is most common during winter and rainy seasons.

Where is the fuse box located in the Grand Cherokee?

The fuse for the Grand Cherokee is located at the front right of the engine cover. Car fuses are a type of current fuse; when the circuit current exceeds twice the rated current of the fuse, it will melt within seconds to protect the circuit. The function of car fuses: When a circuit malfunctions or behaves abnormally, the current may continuously rise, potentially damaging important or valuable components in the circuit, or even causing the circuit to burn out or start a fire. If a fuse is correctly installed in the circuit, it will melt and cut off the current when the current rises abnormally to a certain level and duration, thereby protecting the safe operation of the circuit. Precautions for replacing car fuses: Replace the fuse according to the rated current value indicated on the fuse box cover. Do not use a fuse with a higher rated current than specified. If the new fuse blows immediately, it indicates that there may be a fault in the circuit system, and it should be repaired as soon as possible. In the absence of a spare fuse, you can temporarily replace it with a fuse from other equipment that does not affect driving or safety in an emergency. If you cannot find a fuse with the same current load, you can use one with a lower rated current than the original fuse.
