When your car starts making a funny noise or the check engine lights flashes on, it’s probably time to head to a mechanic for a tuneup. But just what does this catch-all car maintenance task entail? Tuneups have changed a lot as technology and manufacturing in cars have advanced in recent years. Learn just how far we’ve come—and what your vehicle still needs—in the guide below.

How Have Tuneups Changed Over the Years?

In the past, car maintenance teams used these appointments to literally “tune” engine parts, fixing ignition timing and idle speed as well as base timing and emission functions. They also replaced spark plugs, if necessary, and checked on the fuel mixture.

However, while the term “tuneup” still refers to a car maintenance process that optimizes engine performance, there’s not much under the hood of modern cars that can be “tuned” in the traditional sense. Today’s vehicles are much more computer-centric, with the engine computer controlling ignition timing, idle speed, and fuel mixture.

So What Do They Involve Today?

Tuneups still consist of replacing worn-out spark plugs as well as completing other tasks that ensure optimal engine performance. The rise of computer systems in vehicles allows car maintenance teams to use computers for diagnostic testing, which can scan for fault codes, gauge repair needs, and learn details about a car’s condition by tapping into its electronic system.

Still, some adjustments need to be made manually. Mechanics will replace air and fuel filters, check and top off fluid levels, and complete an engine oil change. They may also perform a fuel-injection service depending on your vehicle’s specific service requirements. Other aspects of a modern tuneup include checking and recharging batteries and visually inspecting the belts and hoses inside the engine.
