Here are the fluids that a car needs: 1. Fuel: Fuel is the most consumed liquid in a car, serving as the engine's fuel and the source of all power for the vehicle. 2. Engine Oil: Engine oil is the 'blood' of the engine, acting as the working medium for the engine's lubrication system. It provides lubrication, cleaning, cooling, sealing, anti-corrosion, anti-rust, buffering, and shock absorption. 3. Transmission Fluid: Transmission fluid lubricates and cools the transmission and serves as the working medium for the control system in automatic transmissions. 4. Brake Fluid: Brake fluid is the working medium that transmits braking pressure in the hydraulic braking system. It is divided into three main types: glycol-ether, ester, and silicone, with glycol-ether and ester types being the most commonly used. 5. Power Steering Fluid: Power steering fluid is a medium oil added to the power steering system, helping to transmit steering force and provide buffering. 6. Coolant: The car's antifreeze is the working medium for the engine cooling system, offering functions such as antifreeze, anti-boil, anti-corrosion, anti-scale, and lubrication of cooling system components. 7. Windshield Washer Fluid: Windshield washer fluid, commonly known as glass water, is a consumable in car use. It provides cleaning, antifreeze, anti-fog, anti-static, lubrication, and anti-corrosion functions.

How to Troubleshoot When the Urea Warning Light Comes On?

Methods to troubleshoot when the urea warning light comes on: 1. If the vehicle experiences poor acceleration or white smoke from the exhaust pipe, professional equipment is needed to clean the urea crystallization inside the exhaust pipe; 2. If the vehicle's fault code indicates low urea pressure, it is necessary to replenish the urea; 3. If the engine torque is limited and the RPM cannot exceed 1800 per minute, the urea pump and sensor need to be replaced. Automotive urea is a high-purity transparent liquid with a faint ammonia odor, alkaline but non-toxic. Failure to load diesel exhaust fluid (DEF) or using impure or substandard DEF can cause the vehicle's engine to automatically reduce speed. Poor-quality DEF can contaminate the catalyst in the SCR catalytic reaction tank, leading to serious consequences.

Reasons Why Ford Transit Fails to Start

Here are the reasons why a Ford Transit may fail to start: 1. Insufficient battery charge - timely and effective replenishment is needed: When the battery charge is low, the engine cranks weakly during startup, and you may only hear abnormal noises. Try pressing the accelerator while turning the key, and continuously pump the throttle. When the vehicle shudders and is about to start, ease off the throttle slightly to avoid damaging the vehicle by stomping on the accelerator. Avoid continuous ignition attempts to prevent complete battery drain. 2. Untimely spark plug replacement: Spark plugs are a key component of a car engine's ignition system. Every gasoline engine is equipped with spark plugs, typically one per cylinder, with rare high-speed gasoline engines having two spark plugs per cylinder.

What is the minimum ground clearance of the Kuga?

The minimum ground clearance of the Kuga is 180mm. Minimum ground clearance refers to the distance between the vehicle's support plane and the lowest point in the middle area of the vehicle, which is the distance from the most protruding part of the car chassis to the horizontal ground. The minimum ground clearance must ensure the vehicle's passability when driving on rough roads or going up and down slopes, i.e., to prevent the bottom from touching the ground. Taking the 2019 Kuga as an example, it belongs to the compact SUV category, with a body size of 4525mm in length, 1838mm in width, and 1685mm in height, and a wheelbase of 2690mm.

Why is the license plate reversed in the rearview mirror?

When viewed in the rearview mirror, the license plate appears reversed because the rearview mirror is installed front-to-back, causing the image to be inverted front-to-back relative to the mirror, not left-to-right. The car's rearview mirrors are located on the left and right sides of the front of the vehicle as well as inside the car at the front. These mirrors reflect the conditions behind, beside, and below the car. The key points for adjusting the interior rearview mirror are: position the distant horizon along the centerline of the mirror, then adjust left and right until the image of your right ear just appears at the left edge of the mirror. The purpose of the interior rearview mirror is to expand the driver's field of vision and reduce the occurrence of safety incidents.
