1 Answers

Five oils refer to: gasoline, engine oil, transmission oil, brake fluid, and power steering fluid; three fluids refer to: antifreeze, windshield washer fluid, and battery fluid. Collectively, they are known as the five oils and three fluids. Below is a detailed introduction to the five oils and three fluids: 1. Gasoline: The primary fuel for cars. Engine oil: Lubricates and cools the engine, protecting it. 2. Transmission oil: Lubricates and cools the transmission, generally recommended to be replaced every 60,000 kilometers. 3. Brake fluid: Should be replaced once a year or every 20,000 kilometers, as old brake fluid absorbs too much moisture, lowering its boiling point and potentially causing vapor lock under intense or frequent braking, leading to brake failure. 4. Power steering fluid: Uses hydraulic action to make steering easier. 5. Antifreeze: Full name is antifreeze coolant, meaning a coolant with antifreeze properties, preventing the coolant from freezing in cold winter conditions, which could crack the radiator or damage the engine block or cylinder head. 6. Windshield washer fluid: Cleaning water for the wipers. 7. Battery fluid: Most cars sold today come with maintenance-free batteries, so you only need to check the battery's inspection window to observe the color and determine the battery's condition.

What Causes High Fuel Consumption in Diesel Vehicles?

Diesel vehicles may experience high fuel consumption due to issues such as poor injector atomization, fuel injection pump failure, incorrect fuel supply timing, advance mechanism malfunction, turbocharger failure, air leaks in intake/exhaust and turbo intercooler pipes, as well as minor cylinder scuffing or bearing seizure. Below are preventive measures for diesel engine fuel system problems: 1. Inspect components in the low-pressure fuel circuit: Regularly check fuel pipes, pipe joints, sealing gaskets, and the sealing condition of fuel transfer pumps and hand primer pumps in the low-pressure circuit. Repair or replace any fuel leaks or air ingress promptly. Replace low-pressure fuel pipes if cracked or with sand holes, and renew joint gaskets when damaged, uneven, grooved, or burred. 2. Fuel pipe routing: Ensure fuel pipes don't contact sharp-edged components or engine parts to prevent wear-induced leaks. Avoid arbitrarily bending pipes to alter routing, which may cause dents or breaks. Where possible, wrap pipes with metal wire for protection. 3. After fuel tank depletion: When refueling after complete tank depletion, promptly bleed all air from the fuel system.

Will Insurance Cover a Broken Vehicle Transmission?

If the vehicle transmission fails due to its own inherent defects, the insurance company will not provide coverage. In such cases, you can apply for after-sales compensation from the car seller or manufacturer. However, if the vehicle sustains severe damage in an accident, with the transmission showing obvious impact marks, you can file a claim with the insurance company. Below is an introduction to transmissions: 1. Overview: The automotive transmission primarily refers to the gearbox of a car, which is divided into manual and automatic types. A manual transmission mainly consists of gears and shafts, achieving speed and torque variation through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations. 2. Differences: A manual transmission mainly consists of gears and shafts, achieving speed and torque variation through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations.

Which models are equipped with the BMW B48 engine?

Currently, models equipped with the BMW B48 engine include the new 7 Series, new 3 Series, new X1, and new 5 Series, among others. Below are the relevant details: 1. Power versions: The B48 has multiple power versions, namely the 20i with 184 horsepower, 25i with 231 horsepower, 28i with 252 horsepower, and 30Li with 258 horsepower. Although the power output is similar to the N20, the B48 engine can withstand greater torque and has a wider tuning range. 2. Development: The B48 engine can be freely configured into four-cylinder, six-cylinder, or eight-cylinder forms based on a standard cylinder block benchmark, and can be arranged in longitudinal, transverse, or mid-engine layouts, thereby enabling the development of more vehicle models.

Where is the rear drainage hole of the old Sagitar sunroof located?

The rear drainage holes of the old Sagitar sunroof are typically located inside the A-pillars and C-pillars of the vehicle. Here is a detailed introduction about it: 1. Introduction 1: When water enters the sunroof channel, it flows to the drainage holes and then drains out of the vehicle through the drainage tubes. 2. Introduction 2: The sunroof drainage outlets are usually quite hidden, and their locations vary depending on the vehicle model. Even during regular maintenance, professionals at 4S shops may easily overlook them. 3. Introduction 3: If the sunroof leaks, it is necessary to check whether the drainage outlets are clogged with dust. There are no special requirements for the daily maintenance of the car sunroof. Just regularly inspect the surrounding seals for any damage and check the lubrication condition of the tracks.

Why does parallel parking time out?

The reason for exceeding the time limit in parallel parking is failing to exit the parking area promptly. Regarding the parallel parking zone, it starts from 4 meters in front of the parking space, with a total length of 17.7 meters. The parking space itself measures 7 meters in length and 2.5 meters in width. The exercise is considered complete once the vehicle exits the stop line after parallel parking. Tips for parallel parking in Subject 2: 1. Starting: After getting in the car, first adjust the seat properly and fasten the seat belt. 2. Acceleration: Use half-clutch to start, and add appropriate throttle if confident. 3. Reversing: Shift to reverse gear, start with half-clutch, and control the speed. 4. Exiting: Shift to first gear, turn on the left signal, honk the horn, then start slowly using half-clutch.
