What Does a Tune-up Involve?
The first step in a tune-up involves a comprehensive visual inspection of the engine to check for any obvious issues or defects. Technicians also generally check spark plugs, filters, belts, hoses, ignition systems, rotors, and distributor caps. Timing chains and batteries are also inspected and replaced or repaired if necessary. The technician will also check the fuel levels in the car and fill any that are low. Many car owners opt to have an oil change along with a tune-up as well.
Signs You Need an Engine tune-up
Signs that a tune-up is in order vary by vehicle, but the most common ones involve a general failure of the engine to respond as it should. For instance, there may be a noticeable lag between when you put your foot on the gas pedal and the actual acceleration, or the brakes may not be functioning as they should, particularly if the brakes are making whining or scraping noises when you apply the pedal. Other indications include a recent reduction in gas mileage, rough shifting, and any unexplained rattles or vibrations. Of course, if the “check engine” light on your dash comes on, you should get your vehicle to a trusted mechanic as soon as possible.
However, it’s important to remember that even if your vehicle isn’t showing any obvious signs of trouble, it may be time for a tune-up. After all, one of the major goals of regular tune-ups is keeping cars problem-free.
