During an 80,000 km major car maintenance, you need to replace the engine oil, three filters, spark plugs, brake fluid, as well as the engine auxiliary belt and timing belt. Additionally, the throttle body should be cleaned. Below are detailed explanations about the car throttle body: Overview: The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter at the top and the engine block at the bottom, it is often referred to as the throat of the car engine. Classification: Throttle bodies are divided into two types: traditional cable-operated and electronic throttle bodies. In traditional engines, the throttle control mechanism operates via a cable (flexible steel wire) or linkage rod, connecting the accelerator pedal at one end and the throttle linkage plate at the other. Electronic throttle bodies primarily use a throttle position sensor to adjust the throttle opening angle based on the engine's power requirements, thereby regulating the air intake volume.

I've been driving for over 20 years, and 80,000 kilometers is a major milestone that requires comprehensive maintenance. Typically, I change the engine oil and oil filter—these are the lifeblood of the engine. Failing to replace them in time can cause wear and shorten the engine's lifespan. The air filter should also be replaced, as too much accumulated dust can reduce power and increase fuel consumption. The spark plugs need changing too—old ones can cause unstable ignition and even stall the engine mid-drive. Don't skip the fuel filter; a dirty one can clog the fuel injectors and affect fuel efficiency. Brake fluid should be checked and replaced to prevent soft brakes and potential accidents. Coolant replacement is essential to protect the engine from overheating. I also recommend checking the transmission fluid, brake pads, and tires, as these can cause major issues once they reach their wear limits. Don't underestimate these steps—spending money where it counts ensures safety and reliability. I once delayed maintenance, and it ended up costing me thousands in engine repairs. Timely maintenance is the most cost-effective approach.

As a first-time car owner going through the 80,000 km major maintenance, I was quite nervous. The 4S shop said engine oil and oil filter must be replaced to keep the engine lubricated and clean. After they changed the air filter, I felt the airflow became faster. They recommended replacing the spark plugs as the old ones had cracks causing delayed ignition and vibrations. The fuel filter was also replaced to prevent impurities from affecting performance. Transmission fluid was changed too, especially important for automatic cars to avoid gear shifting issues. Brake fluid was tested and replaced due to excessive moisture content, resulting in quicker brake response. The coolant was replaced as it had aged and become ineffective, preventing overheating in summer. The cost wasn't cheap, but it's much cheaper than potential repairs - my friend skipped it last time and ended up with an overheated engine stranded roadside. After maintenance, the car runs smoother and fuel consumption seems slightly lower. Comparing prices at multiple shops can help find more affordable options.

As a car enthusiast, the core of an 80,000-kilometer major maintenance is engine care. Changing the oil lubricates internal components, while the oil filter removes impurities. Replacing the air filter ensures efficient combustion by maintaining clean air intake. Cleaning the fuel filter protects the injection system from contaminants. New spark plugs guarantee precise ignition, preventing misfires and engine shake. Brake fluid absorbs moisture and degrades over time, affecting braking efficiency—replacement is a must. Coolant renewal prevents overheating and corrosion. If you love your car, consider changing the transmission fluid too, especially for city driving where wear is significant. Don’t overlook brake pad checks—replace them if they’re too thin. Flushing the cooling system extends its lifespan. Regular major maintenance can add years to your car’s life with fewer issues. My experience shows that thorough maintenance keeps performance like new. Simple tasks can be DIY, using specialized tools when needed.
