One of the most important car parts that technicians inspect during tune-ups is the engine. Engines are complex, and their health affects cars' operating systems. Technicians thoroughly inspect all car engines to check for signs of wear, fading and malfunction. They also look at engine components to check for their safety and proper functioning. Even small components, like electronic control parts and oxygen sensors, can wear prematurely and necessitate replacement. Technicians also evaluate fuel and air filters and spark plugs.

Even if cars appear to be in good working condition, people should make sure to get tune-ups on a regular basis according to manufacturers' recommendations. This ensures cars work safely and smoothly, and can prevent small problems from becoming catastrophic. People should schedule tune-ups at least once annually, say authors at Goodyear, and more frequently if they suspect a problem.
