Taking care of your car for long-term performance is not just about washing it or filling up the gas tank. The auto parts inside the vehicle are equally important. Understanding the function of key car spare parts ( อะไหล่ รถ ยนต์ )specially those related to driving and safety helps drivers stay informed, plan maintenance properly, and prevent costly breakdowns.
In this article, we’ve gathered the 10 most important auto parts that every car owner should know.
10 Essential Car Spare Parts You Must Know
1. Brake Pads
Small but vital, brake pads create friction against the brake disc to slow the car down. Worn-out brake pads increase stopping distance and the risk of accidents. Replace them when they become thin, noisy, or feel unreliable during braking.
2. Car Battery
The battery powers ignition and supplies electricity to systems such as headlights, air conditioning, and the radio. A weak battery can prevent the car from starting. Typical lifespan is 1.5 to 3 years, depending on brand and usage.
3. Air Filter
The air filter prevents dust and debris from entering the engine, ensuring efficient combustion. A clogged filter reduces fuel efficiency and acceleration. It should be replaced every 20,000–30,000 km or when visibly dirty.
4. Engine Oil
Engine oil lubricates moving parts, reduces heat, and prolongs engine life. Running low or using degraded oil can severely damage the engine. Change oil every 5,000–10,000 km, depending on oil type.
5. Spark Plug
Spark plugs ignite the air-fuel mixture in the combustion chamber. Worn plugs cause hard starts, rough idling, and poor fuel economy. Regular replacement ensures smooth engine performance.
6. Shock Absorbers
Located in the suspension system, shock absorbers cushion impacts from the road, making driving smoother and more stable. Worn shocks cause bouncing and poor handling. Inspect every 40,000–50,000 km or when stability feels compromised.
7. Car Tires
Tires are the only contact between the car and the road. Good tires should have sufficient tread depth, no cracks, and no bulges. Worn tires affect grip and braking. Lifespan is usually 3–5 years or when tread depth falls below 1.6 mm.
8. Drive Belt (Serpentine Belt)
The drive belt transfers power from the engine to systems like the alternator, water pump, and air conditioning. A broken belt can cause sudden breakdowns. Replace if cracked, noisy, or after 60,000–100,000 km.
9. Radiator
The radiator cools the engine by dissipating heat. A clogged or leaking radiator can cause overheating and engine failure. Regularly check coolant levels and flush the system annually.
10. Wheel Bearings
Wheel bearings allow the wheels to rotate smoothly. Worn bearings cause humming noises or vibrations and can lead to loss of control. Inspect every 40,000–60,000 km or if you hear unusual sounds from the wheels.
Conclusion
Every auto part plays a crucial role in driving safety and efficiency. Even small components can cause major issues if neglected. By understanding the function of essential car spare parts and performing timely maintenance, you can prevent breakdowns, reduce long-term costs, and ensure safer journeys.
