How to Drive Through Deep Water Areas with a Car

When driving through deep water areas, the water depth should be assessed first. Since the water on the road is relatively dirty, it's difficult to judge the depth, especially on uneven surfaces. The safest approach is to park the car in a safe spot and observe how other vehicles navigate the flooded area. If vehicles of similar height can pass, it generally indicates safe passage. If no similar vehicles are present, using a branch to measure the water depth is advisable. The vehicle manual specifies the safe and dangerous water levels, indicating the maximum water depth your car can handle. When water reaches half the wheel height, the car's chassis may be submerged, and the exhaust pipe could be in contact with water. Poorly sealed components might leak, requiring reapplication of lubricant or rust removal. For most family cars, water up to one-third of the wheel height is relatively safe. At two-thirds of the wheel height, the battery may get flooded. If the car moves too quickly, water could enter the air intake, potentially causing severe engine damage. Key precautions when driving through water: For vehicles with auto start-stop, manually disable this feature before entering water. If the engine stalls, the system might attempt to restart it, leading to major repairs. Drive slowly in low gear without stopping, accelerating gently, avoiding sharp steering or gear changes. Never attempt a second ignition if the engine is flooded—this could destroy the engine. Instead, exit the vehicle and wait for assistance. Avoid driving side by side with other cars through flooded areas. Maintain distance and pass one by one to prevent water splashed by other vehicles from entering your air intake. After crossing, perform several light brake applications to dry the brake discs and pads through friction.

What kind of oil does the Nissan QR25 engine use?

Nissan QR25 engine uses 5W/40 synthetic oil. The role of engine oil: As a lubricant for the engine, engine oil continuously flows into various transmission components during engine operation, forming an oil film between friction surfaces, thereby reducing friction resistance, lowering power consumption, and minimizing component wear. Precautions for using engine oil: The selection of engine oil should be based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Therefore, it is advisable to choose multi-grade oil, which offers advantages such as economy, long service life, and high efficiency, providing better protection for the engine. Due to the characteristics of multi-grade oil, phenomena such as premature darkening and lower oil pressure compared to conventional oil may occur during use, which are normal.

Should You Press the Clutch When Braking in a Car?

You do not need to press the clutch when braking in a car. The correct method is to first press the brake to reduce speed, then press the clutch for gear shifting. When the car's speed is very low, remember to press the clutch to avoid stalling the engine. The purpose of braking is to decelerate, which can either reduce speed or bring the vehicle to a complete stop. The principle of braking involves converting the car's kinetic energy into heat energy to dissipate it. The car's clutch is located within the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch serves as the input shaft of the transmission. During driving, the driver can press or release the clutch pedal as needed to temporarily disconnect or gradually reconnect the engine and transmission, thereby cutting off or transmitting the engine's power to the transmission.

Will the hood break if slammed shut?

The engine hood has two buffer rubbers underneath that serve as shock absorbers! However, if you frequently slam it shut with force, these buffer rubbers can easily get damaged. Therefore, it's important to be careful when closing the hood in the future. Introduction to the Engine Hood: The engine hood (also known as the bonnet) is one of the most prominent body components and a part that car buyers often inspect. The main requirements for an engine hood are heat insulation, sound insulation, lightweight, and high rigidity. Engine Hood Structure: The engine hood is generally composed of an outer panel and an inner panel, with heat insulation material sandwiched in between. The inner panel enhances rigidity, and its geometric shape is chosen by the manufacturer, typically in a skeletal form.

How long will it take for a driver's license to be revoked if 12 points are deducted and not processed?

If a driver's license is deducted 12 points and the driver fails to participate in the study and examination within 35 days, the traffic management department of the public security organ will announce the suspension of the use of their motor vehicle driver's license. Relevant regulations: If a motor vehicle driver accumulates 12 points in a scoring cycle, the traffic management department of the public security organ shall detain their motor vehicle driver's license. Participation in study: The motor vehicle driver shall, within 15 days, participate in a seven-day study of road traffic safety laws, regulations, and related knowledge at the traffic management department of the public security organ where the driver's license was issued or where the violation occurred. After the motor vehicle driver completes the study, the vehicle management office shall conduct an examination on road traffic safety laws, regulations, and related knowledge within 20 days.

How Many Times Will Cylinder Wear Increase Without an Air Filter in the Engine?

Without an air filter, cylinder wear in the engine will increase by 8 times. Hazards of operating an engine without an air filter: During operation, the engine draws in a large amount of air. If the air is not filtered, the suspended dust particles in the air will be drawn into the cylinder, accelerating the wear of the piston assembly and the cylinder. Larger particles entering between the piston and cylinder can cause severe "cylinder scoring," especially in dry and sandy working environments. The air filter is installed at the front of the intake pipe to filter out dust and sand particles, ensuring that sufficient and clean air enters the cylinder. Types of air filters: Air filters generally come in two types: paper and oil-bath. Paper filters are widely adopted due to their advantages of high filtration efficiency, light weight, low cost, and easy maintenance. The filtration efficiency of a paper filter element can exceed 99.5%, while the oil-bath filter typically achieves 95-96% filtration efficiency under normal conditions.
