What Needs to Be Replaced During an 80,000 km Major Car Maintenance?

[WalkerLee]

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.
