A car service can vary depending on the provider and the type of service package you select, but typically, it includes several standard procedures to ensure the proper functioning and maintenance of your vehicle. Here are some common elements of a car service:

1. Oil Change: This involves draining the old engine oil and replacing it with fresh, clean oil.

2. Oil Filter Replacement: The oil filter is usually replaced along with the oil change to ensure optimal filtration of contaminants.

3. Fluid Checks and Top-Ups: This includes checking and refilling fluids such as coolant, brake fluid, transmission fluid, and power steering fluid as needed.

4. Tyre Inspection and Rotation: Tyres are inspected for wear and tear, and if necessary, they are rotated to ensure even wear across all tyres.

5. Brake Inspection: Brakes are inspected for wear and tear, and brake pads, rotors, and brake fluid may be replaced if needed.

6. Battery Check: The battery is inspected to ensure it's functioning properly and may be tested for charge and voltage.

7. Air Filter Replacement: The air filter is inspected and replaced if necessary to ensure clean air flow to the engine.

8. Spark Plug Replacement: Spark plugs may be replaced to ensure proper ignition and combustion within the engine.

9. Suspension and Steering Inspection: The suspension and steering components are inspected for wear and tear, and adjustments or replacements may be made as needed.

10. Visual Inspection: A comprehensive visual inspection of the vehicle is performed to identify any potential issues or areas needing attention.

11. Diagnostic Scans: Modern vehicles often have onboard diagnostic systems that can be scanned for any error codes or issues that may not be apparent during a visual inspection.

12. Wiper Blade Replacement: Wiper blades are inspected and replaced if necessary for optimal visibility during inclement weather.

13. Exhaust System Inspection: The exhaust system is inspected for leaks, damage, or other issues that may affect vehicle performance or emissions.

14. Scheduled Maintenance Items: Depending on the mileage and age of the vehicle, scheduled maintenance items recommended by the manufacturer may be performed during the service.

These are just some of the common components of a car service, but the exact procedures can vary based on factors such as the type of vehicle, its age, and any specific concerns or issues identified during the service. It's essential to consult with your service provider to understand precisely what's included in the service package they offer.
