Generally, the items included in a major vehicle maintenance service are the engine and engine oil, oil filter, air filter and fuel filter, brake fluid, coolant, transmission fluid, power steering fluid, spark plugs, etc. Below is a detailed introduction to vehicle maintenance items: 1. Engine oil and oil filter replacement: This mainly involves maintenance of the lubrication system, whose primary function is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's function is to remove various impurities from the engine oil to ensure the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, a car should undergo maintenance every 5,000 kilometers. 2. Filter replacement: The air filter's role is to filter the air before it enters the cylinder, removing impurities such as dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The fuel filter is generally replaced after driving 20,000 to 25,000 kilometers. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission fluid, the battery, throttle body, fuel injectors, and brake pads are all part of the inspection items during routine maintenance, and their maintenance depends on usage conditions.

A major service might sound like a big task, but it's actually quite systematic. Typically, the items we cover include an oil and oil filter change, which is the core of maintenance, keeping the engine lubricated and clean. The air filter is inspected or replaced to maintain intake efficiency and fuel economy. Spark plug replacement is crucial, as worn-out plugs can lead to poor ignition and difficulty starting the engine. Then, we inspect or replace components of the braking system, such as brake pads, discs, and brake fluid, to ensure reliable stopping power. Coolant replacement prevents the engine from overheating and potential damage. Tire rotation and wheel alignment prevent uneven wear and unstable driving. Additionally, we perform a battery test and replace the cabin air filter to maintain fresh air inside the vehicle. Other details include checking the transmission fluid and inspecting the suspension system to prevent damage from rough driving. Regularly performing these services can save on repair costs in the long run and keep the car running smoothly. I recommend a major service every 40,000 kilometers, adjusting as needed based on the vehicle's condition to avoid unnecessary expenses from over-maintenance.

The major maintenance service is quite comprehensive, and I usually approach it in several steps. The basics include changing the engine oil and filters to keep the engine running smoothly; the air filter is replaced when dirty to improve combustion efficiency and reduce fuel consumption. Key components like spark plugs are inspected and replaced if worn out, as they can affect power output. The braking system must not be neglected—replacing brake fluid and pads ensures safe stopping distances. The cooling system is managed by replacing coolant to prevent engine overheating damage. For tires, rotation, balancing, and alignment are done to extend their lifespan and ensure stability at high speeds. Additionally, battery life tests and cabin air filter replacements are performed, along with checks on transmission and power steering fluids. Extra items like suspension inspections and light adjustments may be included, but the core focus is preventive maintenance. I follow the vehicle manual's guidelines, scheduling this service every 30,000 to 50,000 kilometers. Regular minor upkeep in between saves money and enhances durability, preventing unexpected breakdowns that could disrupt travel plans.

The major maintenance service includes quite a few items, typically involving oil and oil filter replacement, which forms the foundation of maintenance. Spark plug inspection or replacement ensures smooth ignition and quick engine response. The braking system is checked with possible brake pad and fluid replacement; coolant renewal prevents overheating issues. Tire rotation avoids uneven wear; battery testing maintains health to prevent starting failures. Cabin air filter replacement ensures good air quality; minor items like headlight adjustment are often included. Overall, it enhances reliability and fuel efficiency, making the car more enjoyable to drive.
