When adjusting, first loosen the lock nut and adjusting screw, insert a feeler gauge of the same thickness as the specified valve clearance between the valve stem and rocker arm of the valve to be adjusted. Rotate the adjusting screw and pull the feeler gauge back and forth until slight resistance is felt. After tightening the lock nut, recheck the clearance. If there is any change, readjustment is required. There are two main methods for adjusting valve clearance: 1. Cylinder-by-cylinder adjustment method: This method only requires turning the cylinder to be adjusted to the top dead center of its compression stroke (at this time, both the intake and exhaust valves are completely closed) to adjust the valve clearance. This method requires finding the top dead center of each cylinder's compression stroke and remembering the firing order of the engine (ignition order for gasoline engines and injection order for diesel engines). 2. Two-step adjustment method: This method adjusts all valves on the engine in two steps. It is simple to operate and highly efficient. No matter how many cylinders there are, only two adjustments are needed to complete the entire process.

What is the reason for the engine fault light coming on and then turning off after restarting?

The engine fault light coming on and then turning off after restarting is part of the self-check process when starting the vehicle. This phenomenon is normal and there is no need to worry. During the use of motor vehicles, it is important to always pay attention to whether the dashboard still shows any fault lights. If a fault light appears, a dedicated diagnostic computer can be used to detect the problem for repair. Below are some related extended information about the engine fault light: 1. The engine fault light detects whether the exhaust emissions are normal through sensors. If the emissions exceed the standard, the engine warning light will come on. In most cases, if the light comes on and then turns off after restarting, it indicates that there is no problem with the vehicle. 2. The reason is likely that some issues occurred due to poor atomization in the fuel engine cylinders just after starting the vehicle, causing the engine to alert. When the temperature rises, the warning light will naturally turn off.

What does the white rectangular marking box mean?

The white rectangular marking box indicates a yield line, typically placed 5-30 meters before the stop line at intersections of non-main roads. It signals drivers to slow down and yield the right-of-way to vehicles on the main road. The yield line requires drivers to reduce speed or stop, observe traffic conditions on the main road, and proceed only when it is safe to do so, ensuring priority for vehicles on the main road. At intersections marked with yield lines, vehicles must come to a complete stop and yield to vehicles on the main road. This marking is usually used in conjunction with a "Yield" sign. The yield line consists of two parallel dashed lines and an inverted triangle, all in white. Deceleration markings often appear at exit ramps, toll plaza areas, or other sections where vehicles need to slow down. They can be categorized into transverse deceleration markings (perpendicular to the direction of travel) and longitudinal deceleration markings, which may appear as single, double, or triple dashed lines. Transverse deceleration markings are a series of parallel white dashed lines designed to alert drivers to reduce speed.

Where is the engine number of Nissan Kicks located?

The engine number of the 2019 Nissan Kicks is generally located on the engine block. Open the hood, and you can see the identification number on the engine, which is usually a combination of 7 to 8 digits and letters. In addition to the above method, the engine number can also be viewed through the following 4 ways: The vehicle's driving license has the engine number printed on it, usually located on the second last line; The motor vehicle registration certificate will state the engine number; The car purchase invoice will state the engine number; The vehicle purchase tax payment certificate will state the engine number. It should be noted that the engine number is not the same as the engine model. The engine model refers to the specification and size of the engine within the manufacturer, and engine models can be the same. The engine number refers to the production number of the engine, where each engine can only use one engine number and each engine's number is unique.

How Many Points Are Deducted for Driving Without Wearing a Seatbelt and Using a Phone?

Driving while using a phone and not wearing a seatbelt typically results in a deduction of 5 points, which includes 3 points for using a phone while driving and 2 points for not wearing a seatbelt. However, there is a scenario where only 3 points are deducted. For instance, if the offense occurs on roads other than highways or urban expressways, not wearing a seatbelt may not lead to point deduction but only a fine. In this case, only the 3 points for using a phone while driving are deducted. Dangers of Driving Without Wearing a Seatbelt and Using a Phone: Using a phone while driving is inherently dangerous, and doing so without wearing a seatbelt is even more hazardous. In the event of an unexpected situation or accident, the driver may bear the primary responsibility for the accident. Using a phone while driving also distracts the driver's attention. If the vehicle in front suddenly brakes, the driver behind may fail to brake in time due to being on the phone, increasing the likelihood of a collision. Worse still, in severe accidents, not wearing a seatbelt could result in the driver being ejected from the vehicle, among other serious consequences.
