1. Engine Oil and Filter

Every car needs engine oil. It lubricates moving parts and keeps everything running smoothly. Don’t forget to replace the oil filter. This part traps dirt and contaminants. Without it, your engine can suffer serious damage. It's simple – change the oil and filter regularly.

2. Spark Plugs

Next up are spark plugs. These small yet vital components ignite the air-fuel mixture in the engine. If they wear out, your engine may misfire or run poorly. Regularly check and replace spark plugs to ensure optimal performance. How often should you check them? Typically, every 30,000 miles is a good rule of thumb.

3. Timing Belt or Chain

Your Buick might have a timing belt or chain. This piece keeps the engine’s components in sync. If it fails, your engine can suffer serious damage. Check your owner's manual for the recommended replacement interval. Ignoring this can lead to costly repairs.

4. Fuel Pump

A properly functioning fuel pump is another key part. It sends gasoline to the engine. If your engine struggles to start, the fuel pump could be the issue. Regular checks can prevent this common problem.

5. Water Pump

The water pump is essential for maintaining proper engine temperature. It circulates coolant throughout the system. If it fails, your car can overheat. Replacing the water pump according to your vehicle’s maintenance schedule is wise.

6. Radiator

The radiator works closely with the water pump. It cools the engine by dissipating heat. Regularly inspect it for leaks or damage. An efficient radiator helps in keeping your engine running smoothly.

7. Exhaust System Components

Your exhaust system includes several parts like the muffler and catalytic converter. These components reduce harmful emissions and noise from your vehicle. Over time, they can become rusted or clogged. Regular checks can save you from unexpected issues.

8. Air Filter

The air filter is often overlooked but is crucial for engine health. It ensures clean air enters the engine. A clogged filter can reduce performance and fuel efficiency. Change it every 12,000 to 15,000 miles for best results.

9. Gaskets and Seals

Gaskets and seals are important for preventing oil and coolant leaks. Inspect them regularly. If you notice any leaks, it's time to replace these parts. A small issue can quickly turn into a much larger problem if not addressed.
