Why Does the Car's Low Coolant Warning Light Come On?

The low coolant warning light resembles a thermometer with two wavy lines beneath it. This indicator illuminates on the dashboard when the vehicle is low on coolant. The solution is to promptly add coolant and then check for any leaks. Precautions for using coolant: 1. Do not mix brands: Try to use the same brand of coolant. Different brands of coolant use different metal corrosion inhibitors, so they should not be mixed. 2. Pay attention to the expiration date: Most coolants have a shelf life of two years (some products may last longer). When adding coolant, make sure the product is within its expiration date. When replacing, drain the old coolant completely, clean the cooling system thoroughly, and then add new coolant. 3. Do not dilute with water: Traditional inorganic coolants should not be diluted with water, as this can cause sedimentation and severely affect the coolant's normal function. Organic coolants can be diluted with water, but the amount of water added should not be excessive.

Should the Volkswagen Sagitar use 92 or 95 octane gasoline?

Volkswagen Sagitar's official website recommends using gasoline with an octane rating of 92 or higher, and 95 octane gasoline can also be used. 92 octane gasoline refers to gasoline with an octane value of 92, which is suitable for mid-range cars. The Sagitar is a classic model under FAW-Volkswagen. According to the Sagitar's official website, this model alone comes with three engine displacements: 1.6L, 1.2T, and 1.4T, along with a high-power 2.0T engine. Different engine types require different gasoline. Below is an introduction to the Volkswagen Sagitar: 1. The new generation Sagitar Long-Wheelbase is built on the MQB A2 platform, achieving comprehensive innovation in design concepts, comfort and safety, and spatial layout. The target audience for the new generation Sagitar Long-Wheelbase is the new middle class, primarily composed of post-80s and post-90s generations—stylish, life-enjoying, goal-oriented future elites who aspire to a tasteful life. For them, the essence of consumption upgrade is not about consuming high-end brands or products in the traditional sense but about a comprehensive improvement in quality of life. 2. The new Sagitar is equipped with ergonomically designed seats, a large-sized sliding panoramic sunroof, a three-zone automatic air conditioning system, and Dynaudio audio. In terms of space: the new generation Sagitar Long-Wheelbase has body dimensions of 4753mm in length, 1800mm in width, and 1462mm in height, with a wheelbase extended to 2731mm.

Will Asphalt Sticking to Tires Damage Them?

Tires with asphalt sticking to them will not be damaged. Car tires are one of the important components of a vehicle, directly in contact with the road surface, working together with the suspension system to cushion the impact during driving, ensuring good ride comfort and smooth driving. The causes of tire wear are as follows: 1. Excessive wear on both sides, mainly due to insufficient inflation or long-term overloading. When inflation is low or the load is heavy, the contact area between the tire and the ground increases, causing both sides of the tire to engage with the ground and resulting in premature wear. 2. Excessive wear on one side, primarily caused by misaligned front wheel positioning. When the camber angle of the front wheels is too large, the outer edges of the tires experience premature wear; if the camber angle is too small or nonexistent, the inner edges wear prematurely. 3. Sawtooth-shaped wear on the tread, mainly due to improper front wheel alignment or issues with the front suspension system, such as loose ball joints, causing normally rolling wheels to slip or continuously change alignment during driving, leading to sawtooth-shaped tire wear.

Will driving below 80 km/h on the highway result in penalty points?

Whether driving below 80 km/h on the highway will result in penalty points depends on the minimum speed limit of the specific lane. If the minimum speed limit of the lane is greater than 80 km/h, driving below 80 km/h will result in penalty points; otherwise, it will not. According to Article 78 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": Highways shall indicate the speed limits for each lane. The maximum speed shall not exceed 120 km/h, and the minimum speed shall not be lower than 60 km/h. On highways, the maximum speed for small passenger vehicles shall not exceed 120 km/h, for other motor vehicles shall not exceed 100 km/h, and for motorcycles shall not exceed 80 km/h. For roads with two lanes in the same direction, the minimum speed for the left lane shall be 100 km/h; for roads with three or more lanes in the same direction, the minimum speed for the leftmost lane shall be 110 km/h, and the minimum speed for the middle lane shall be 90 km/h. If the speed limit indicated by road signs is inconsistent with the above lane speed regulations, drivers shall follow the speed limit indicated by the road signs. Article 90 of the "Road Traffic Safety Law of the People's Republic of China" stipulates: If a vehicle is driven on the highway at a speed 20% or more below the prescribed minimum speed under normal conditions, a fine will be imposed, and 3 penalty points will be recorded. If the driving speed on the highway is less than 20% below the minimum speed limit, no fine will be imposed. If the vehicle speed on the highway is below the minimum speed limit due to road construction, traffic congestion, or bad weather such as rain or fog, no penalty will be imposed.

What is the tube above the spark plug?

The long component above the spark plug is called the ignition wire, also known as the spark plug wire, distributor wire, or high-voltage ignition wire. The spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, surface-gap spark plugs, and surface-discharge spark plugs. Spark plugs are installed on the side or top of the engine. In early designs, spark plugs were connected to the distributor via ignition wires. Over the past decade, most car engines have switched to direct connection between the ignition coil and the spark plug. Spark plug working principle: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily isolates the metal shell from the center electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. Current passes through the terminal nut and center electrode, then ionizes the medium between the center electrode and ground electrode to generate a spark, thereby igniting the air-fuel mixture in the cylinder.
