Oil filter refers to the engine filter, also known as the oil element, which is used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from the oil to protect the engine. Oil filters are divided into full-flow and bypass types. The full-flow filter is connected in series between the oil pump and the main oil passage, thus filtering all the lubricating oil entering the main oil passage. The bypass filter is connected in parallel with the main oil passage and only filters part of the lubricating oil pumped by the oil pump. During engine operation, metal wear debris, dust, oxidized carbon deposits and gum deposits at high temperatures, water, etc., are continuously mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and gums, keeping the lubricating oil clean and extending its service life.

How to Remove the Taillight of a Sagitar?

The method for removing the rear taillight of a Sagitar is as follows: First, open the rear trunk and pry open the black cover. After prying it open, you can see the fixing screws of the taillight. Use a socket tool to loosen all the screws, and then you can take it out. When removing the taillight, first unplug the bulb connector. Extension: 1. Brake lights, generally installed at the rear of the vehicle, are red in color to enhance the penetration of the light source, so that vehicles behind can easily detect the braking of the vehicle in front even under low visibility conditions, thereby preventing rear-end collisions. 2. Turn signals are important indicator lights that are turned on when the vehicle is turning to alert vehicles and pedestrians around. The turn signal tube uses xenon tubes, controlled by a single-chip microcomputer circuit, working continuously with alternating left and right flashes.

Under what circumstances is the L gear used?

L gear is used when going downhill. The following is an introduction to the gears of an automatic transmission: 1. P gear: P gear is used when parking by moving the gear selector to the P position, which locks the transmission's parking brake device to the output shaft. Tighten the hand brake. The car will not move. 2. R gear: R gear is the reverse gear, used when reversing. Never engage the reverse gear before the car has come to a complete stop, otherwise the transmission will wear out quickly. 3. D (drive) gear: D gear represents the drive gear, used for normal driving. As long as the gear selector is placed in the D position, the car can automatically adjust the gears while driving. On long downhill slopes, since the D gear of an automatic transmission does not have the engine braking function, you should not keep it in D gear, otherwise the speed will increase, leading to potential safety hazards. 4. L gear: L gear represents the low gear, equivalent to 2nd gear, often used when going up or downhill. 5. S gear: S gear is the sport mode, available in some car models. When the car is in S gear, it can shift freely, but the shifting will be delayed, so the engine will maintain high revs for a longer time, increasing fuel consumption, but it will also provide greater torque output, usually used when overtaking. 6. N gear: N represents the neutral gear, used when starting the car or towing. If waiting at a traffic light for a long time, it is best to shift the car into N gear and tighten the hand brake. However, coasting in N gear (neutral) downhill is prohibited, as it not only does not save fuel but also damages the transmission. 7. M gear in manual-automatic transmission models: This is the manual mode. When switching to M gear, you can shift gears according to your needs by pushing "+" or "-" or using paddle shifters to upshift or downshift.

What is the minimum ground clearance of the Ford Kuga?

The minimum ground clearance of the Ford Kuga is 210mm. Below are the specific details of the Ford Kuga: 1. The body dimensions of the Ford Kuga are 4524mm in length, 1838mm in width, and 1701mm in height, with a wheelbase of 2690mm. The Ford Kuga is an SUV under the Ford brand. 2. In terms of power, the Ford Kuga offers two engine options: the Ecoboost180 (1.5T) and the Ecoboost245 (2.0T), with maximum power outputs of 181 horsepower and 245 horsepower respectively, paired with a 6-speed automatic transmission. Extended information: Minimum ground clearance refers to the distance between the lowest point of the vehicle (excluding the wheels) and the supporting surface when the vehicle is fully loaded and stationary, used to characterize the vehicle's ability to pass over obstacles such as stones and tree stumps without collision.

Can you directly add more engine oil when it's insufficient?

Generally, you can directly add more engine oil when it's insufficient. However, the added oil must be of the same brand and type, and mixing different oils is not allowed. Additionally, opened engine oil can be used for topping up if it's within one year, but oil older than one year is basically ineffective and not recommended for use. Below is relevant information about engine oil selection: 1. Choose engine oil based on the engine's requirements. There's no need to use high-grade oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. 2. It's advisable to choose multi-grade oil whenever possible. Multi-grade oil offers advantages such as cost savings, long service life, and high efficiency, providing better protection for the engine. Due to the characteristics of multi-grade oil, you may observe phenomena like premature darkening or lower oil pressure compared to regular oil during use, both of which are normal.

How often should the brake pads of the Everest be replaced?

The brake pads of the Everest should be replaced every 30,000 to 50,000 kilometers. When the vehicle has been driven over 30,000 kilometers, it is essential to regularly inspect the brake pads to check their actual thickness and ensure immediate replacement once they reach their wear limit. Below is more information about brake pads: 1. Brake pads are one of the critical components of a vehicle's braking system. The pressure from the braking system is transmitted through the piston caliper to the brake pads, and the friction between the brake pads and the brake disc generates the braking force that slows down or stops the vehicle. 2. Brake pads consist of three parts: a steel plate, adhesive material, and friction material. The effective part of the brake pad is the friction material layer. Once this layer is worn out, the braking performance of the pad declines, so the brake pads must be replaced when they wear down to the adhesive layer.

Is Automotive Urea Harmful to the Human Body?

Automotive urea is composed of 32.5% high-purity urea and 67.5% deionized water. Since the human body naturally produces urea, contact with the skin generally does not cause any harm. However, under high temperatures, automotive urea can easily release ammonia gas, which has corrosive properties. Prolonged skin exposure to ammonia may lead to pigmentation or ulcers. Below are the detailed explanations: 1. Under normal circumstances, automotive urea is harmless to the human body (if it comes into contact with the skin, simply rinse with plenty of soapy water or clean water, but avoid contact with eyes or ingestion). However, under high-temperature conditions, automotive urea may release ammonia gas (NH3); 2. NH3 can have corrosive and irritating effects on human skin tissue. Prolonged exposure to ammonia gas may result in symptoms such as skin pigmentation or ulcers. (If such symptoms occur, seek medical attention immediately to prevent more severe consequences).
