What does a car tune up consist of?

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.
