What happens when your car needs a tune up?

A car tune-up is a maintenance service that involves checking, adjusting, and changing certain parts to ensure the engine runs efficiently and reliably. While the specifics of a tune-up can vary depending on the make and model of the vehicle, as well as the recommendations of the manufacturer, a typical tune-up may include the following:

What happens when your car needs a tune up?

1. Spark plug replacement: Over time, spark plugs can wear out, leading to poor fuel combustion and engine performance. During a tune-up, old spark plugs are often changed to maintain optimal combustion.
2. Air filter replacement: The air filter prevents dirt and debris from entering the engine. A clogged air filter can reduce airflow to the engine, affecting fuel efficiency and performance. Changing the air filter is a common component of a tune-up.
3. Fuel system cleaning: Cleaning fuel injectors and the fuel system can help remove deposits and increase fuel efficiency. Some tune-ups may include the use of fuel system cleaners or additives.
4. Ignition system checkup and adjustment: This involves inspecting and adjusting the ignition timing, as well as checking the ignition coils and other parts to ensure proper functioning.
5. PCV valve replacement: The PCV valve helps regulate the flow of gases from the crankcase. Over time, the valve may become clogged or malfunction and may want to be changed during a tune-up.
6. Throttle body cleaning: Cleaning the throttle body can help maintain smooth airflow and optimize engine performance.
7. Check of belts and hoses: The mechanic may inspect the condition of belts and hoses, such as the serpentine belt and timing belt, and change them if necessary.
8. Examination of the distributor cap and rotor: For older vehicles with traditional ignition systems, the distributor cap and rotor may be checked and changed if needed.
9. Battery and charging system inspection: The battery, alternator, and starter may be tested to ensure they function correctly.
