First, rotate cylinder 1 to top dead center (TDC), then align the dot on the balance shaft gear. The balance shaft has a self-weighting force - rotate it to a specific angle for installation. Balance shaft technology is a simple yet highly practical engine technology that effectively reduces vehicle vibration and improves driving comfort. Common causes of loose balance shaft bearings and abnormal wear on bearing seats include poor engine balance and restricted movement of the rolling bearings.

How to Deal with High Fuel Consumption in Nissan Cefiro A33?

There are three main reasons for the high fuel consumption in Nissan Cefiro A33. The first reason could be carbon deposits in the engine, leading to insufficient power, delayed gear shifting, and increased fuel consumption. This is a relatively common issue, and the solution is to clean the carbon deposits in the intake, exhaust, and combustion systems. A simple cleaning can restore the car's fuel consumption to normal. The second reason is that the fuel supply learning value is too high. This is easy to handle—just disconnect the negative terminal of the battery for 30 seconds and then reconnect it. However, ensure that other learning values are not lost, as this could complicate the issue. The final reason is whether there is any dragging in the walking system or brake system. If this fault occurs, the solution is straightforward—take the car to a repair shop or a 4S store for maintenance.

Do you use car mats in your car?

Most people use car mats. The anti-slip teeth on the back of car mats not only effectively prevent sliding but also increase the dust-proof surface, which can effectively prevent rain, snow, and mud from flowing onto the car floor and protect the carpet. Placing your feet on the thick rubber and plush surface feels comfortable and stable. After use, they are very easy to clean, and just rinsing with water can easily remove all dirt. Specifically, they have functions such as waterproofing, noise reduction, and anti-slip. For driving safety, it is best to use original equipment manufacturer (OEM) mats. OEM mats fit perfectly, have appropriate toughness, come with dedicated fixing holes, and also feature anti-slip designs on the bottom, all of which provide excellent anti-slip effects.

Can a screw punctured in the tire sidewall be repaired?

Tire sidewalls punctured by screws cannot be repaired. The sidewall is the most vulnerable part of the entire tire. If the tire is repaired but remains underinflated, high-speed driving causes the tire to heat up during prolonged operation, significantly increasing the risk of a blowout. The functions of tires are: 1. Transmit driving force, braking force, and steering force to enable vehicle control; 2. Support vehicle loads; 3. Absorb shocks and vibrations during driving. Tire maintenance methods include: 1. Regularly remove stones trapped in tire treads; 2. Minimize exposure to direct sunlight; 3. Monitor tire pressure promptly; 4. Prioritize suspension system maintenance; 5. Conduct periodic front wheel alignment checks; 6. Adopt careful driving habits by selecting smooth road surfaces, avoiding objects that may puncture or scratch tires, and steering clear of chemical spills that could corrode tires.

What does brakehold mean on a car?

Brakehold on a car refers to the activation button for the auto hold function. The purpose of auto hold is: 1. The driver does not need to brake for a long time, and when the electronic parking brake is activated, it can prevent unnecessary sliding of the vehicle; 2. The vehicle will not roll back when starting on a slope, avoiding the need for the driver to rely on experience and the handbrake to start on an incline. Precautions for using auto hold include: 1. Auto hold can only function properly when the seatbelt is fastened and the doors are closed; 2. When parking, simply pull the handbrake, shift to P gear, and lock the car—there is no need to worry about whether auto hold is activated; 3. The duration of auto hold on an uphill slope is limited, usually two seconds, so it is necessary to apply the throttle promptly after releasing the brake pedal to avoid the risk of rolling back.
