How many inspections per year for a 20-year-old vehicle?

Where to Check the Standard Tire Pressure?

The standard tire pressure can be checked using a tire pressure gauge. The standard tire pressure is approximately 2.2 to 2.5 bar. Generally, the tire pressure can be slightly lower in summer and slightly higher in winter. If the tire pressure is too low, the deformation of the tire when in contact with the ground will be greater, increasing the contact area between the tire and the ground, which leads to higher driving resistance and heavier steering. To avoid insufficient tire pressure during driving, it is essential to regularly check the tire condition during daily use. If the tire pressure drops, inspect the tire for leaks or punctures, such as from nails. If there is a puncture causing air leakage, it should be repaired promptly or the tire should be replaced directly. If the tire sidewall is punctured, it is recommended to replace the tire immediately.

How Many ABS Sensors Need to Be Replaced If They Fail in a Mercedes-Benz?

Mercedes-Benz ABS sensors should be replaced on a one-to-one basis if they fail. However, before replacement, the sensor should be inspected first, as excessive dirt can also affect the signal. Methods to prevent ABS sensor damage: Maintain sufficient braking distance: When driving on good road surfaces, ensure at least a three-second braking distance from the vehicle ahead. On poor road surfaces, a longer braking distance is required. Keep the sensors clean: ABS wheel sensors and toothed rings are installed on each wheel, so it is essential to regularly clean the sensor probes and toothed rings. Prevent mud, oil, and especially magnetic materials from adhering to their surfaces, as these can cause sensor failure or send incorrect signals to the ABS control unit, affecting the normal operation of the ABS system. Pay attention to brake fluid usage: The ABS system has very high requirements for brake fluid. Therefore, adding or replacing brake fluid must strictly follow the vehicle's user manual instructions, and mixing different types of brake fluid is prohibited.

How to Choose Between Ford Edge and Buick Enclave?

Here are the differences between the Ford Edge and Buick Enclave: 1. Exterior: The Buick Enclave is a better choice in terms of appearance, featuring a beautiful and elegant interior, and a chassis equipped with front enhanced MacPherson suspension and rear five-link independent suspension for excellent driving stability. 2. Applicability: Although it was launched later than the Edge, the Enclave has made a significant impact, offering reassurance and comfort in terms of exterior, interior, power, and driving assistance functions. Its strong exterior, luxurious interior, multiple driving modes, and fuel efficiency make the Enclave stand out. 3. Design: The Edge features a front grille, trunk lid, and door handles with chrome design elements, such as the handles. The Buick Enclave adopts a long nose and short suspension design concept, exuding a strong presence of a large car. It also includes features like the wing-type matrix full LED headlights, 20-inch 12-spoke aluminum alloy wheels, full LED taillights, side car steps, etc. The exterior design of the Buick Enclave seems to resonate more with people.

How to Unclog the Sunroof Drain Pipe of Nissan Sunny?

Here are the methods to unclog the sunroof drain pipe of Nissan Sunny: 1. Syringe injection method: Connect a syringe to an infusion tube, first extract the accumulated water in the drain trough to avoid backflow caused by forced injection. 2. Extract the accumulated water: Fill the syringe with clean water, point the outlet of the infusion tube towards the entrance of the drain pipe, control the force based on the resistance during injection. Once water overflows, use the suction method to extract the dirty water mixture. Repeat this process several times to unclog the drain pipe. 3. Air gun blowing method: Use high-pressure airflow to pressure-clean the drain pipe. When unclogging, wrap a piece of cloth around the nozzle to prevent dirty water from splashing onto clothes and the vehicle. Avoid setting the air pressure too high, as it may cause the rubber joint and drain pipe to detach, worsening the leakage problem. After blowing, pour clean water into the entrance of the drain pipe and check if water flows out from the outlet near the tire mudguard. If water flows out, it indicates successful unclogging.

What are the reasons for difficult cold starts in car engines?

There are several reasons for difficult cold starts in car engines: 1. The cold start injector is clogged with gum deposits, affecting the fuel atomization quality, which causes the cold start injector to fail and not work properly; 2. The thermal switch is short-circuited (contacts normally closed) or open-circuited (normally open). If the contacts are normally closed, the cold start injector will always be in a non-working state; 3. The coolant temperature sensor is faulty, leading to incorrect information transmission; 4. Severe carbon deposits in the intake tract and combustion chamber. The car engine is the device that provides power to the car, acting as the heart of the car, determining its power, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others.

Should the Handbrake Be Pulled After Parking an Automatic Transmission Car?

After parking an automatic transmission car, it is recommended to pull the handbrake in all situations. For the safety of yourself and others, it is advisable for car owners to develop the good habit of pulling the handbrake after parking, especially when parking on slopes. Properly engaging the handbrake can also prevent rolling accidents. The professional term for the handbrake is auxiliary brake, which differs in principle from the main brake. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause plastic deformation of the steel cable. Since this deformation is irreversible, long-term use can reduce its effectiveness and increase the handbrake's travel distance. The handbrake system also includes a return spring. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. With prolonged use, the spring may also undergo corresponding deformation.
