A car tune-up is a routine maintenance procedure aimed at ensuring your vehicle runs smoothly and efficiently. While the specifics can vary depending on the vehicle's age, make, and model, a typical tune-up generally includes the following parts:
- Replacement of Spark Plugs:
- Spark Plugs: Essential for igniting the air-fuel mixture in the engine. Worn or faulty spark plugs can lead to misfires, rough idling, and decreased fuel efficiency.
- Inspection and Replacement of Ignition parts:
- Ignition Wires/Coils: These carry the electrical current from the ignition system to the spark plugs. Over time, they can wear out and cause misfires.
- Distributor Cap and Rotor: These components distribute the electricity to the correct spark plug at the correct time. They are often changed during a tune-up if the vehicle is older.
- Fuel System Inspection:
- Fuel Filter Replacement: The fuel filter prevents contaminants from entering the fuel injectors. A clogged filter can lead to poor engine performance.
- Fuel Injector Cleaning: Ensures the injectors are delivering the proper amount of fuel into the engine's cylinders.
- Air Filter Replacement: The air filter prevents dirt and debris from entering the engine. A clogged air filter can reduce performance and fuel efficiency.
- PCV Valve Inspection/Replacement: The Positive Crankcase Ventilation valve helps regulate the pressure in the engine. A faulty PCV valve can cause engine performance issues and increase oil consumption.
- Inspect and Top Off Fluids:
- Engine Oil and Filter: Regular oil changes are crucial, but during a tune-up, the oil and oil filter are also inspected and changed if needed.
- Coolant: Ensures the engine operates at the correct temperature.
- Brake Fluid, Transmission Fluid, and Power Steering Fluid: These fluids are inspected and topped off or changed as compulsory.
- Battery Check:
- Battery Terminals and Cables: Clean and check for corrosion or wear.
- Battery Condition: The battery's overall health is inspected to ensure it holds a charge correctly.
- Timing and Idle Speed Adjustments (if applicable): On older vehicles, the engine's timing and idle speed might be adjusted to ensure optimal performance.
- Exhaust System Check: Inspect for leaks or damage in the exhaust system, which can affect engine performance and emissions.
- Visual Inspection: A general inspection of belts, hoses, and other parts to identify wear or potential problems that might need addressing.
- Diagnostic Check: Running a diagnostic inspection to identify any trouble codes or problems that might not be visible during a manual inspection.
