What’s Included in a Tune-Up?

Posted December 27, 2022

A mechanic can provide several tune-up services depending on the make and model of your car. This service includes checking and replacing spark plugs, ignition wires, air filters, fuel filters, distributor caps, fuel injection cleaning, and adjusting valves. Read on to find out more about what goes on during a tune-up.

1. Spark Plugs

Spark plugs are designed to ignite the air/fuel mixture in your combustion chamber. During a tune-up, the mechanic will inspect all spark plugs and check their condition. If they appear worn or corroded, they’ll replace them with new ones to ensure your engine runs at its best.

2. Ignition Wires

Ignition wires transfer electric current from the ignition coil to the spark plugs and should be replaced regularly. A tune-up is a time to check for any wear or corrosion in the wires and replace them as necessary. This should be done every 30 thousand to 60 thousand miles.

3. Air Filters

Air filters are an important part of a tune-up because they help remove dirt and other particles from the air entering your engine. When an air filter is clogged, it can reduce the flow of air and make your car less fuel-efficient. That’s why a mechanic will inspect and often replace the air filter.

4. Fuel Filters

The mechanic will check for dirt or debris in the fuel filter that could prevent your engine from getting enough fuel. This is the time for a replacement if necessary.

5. Distributor Caps

These caps protect the distributor and its internal components, preventing corrosion and damage. If signs of wear, such as cracks or leaks appear, the mechanic will replace them.

6. Fuel Injection Cleaning

The fuel injectors work to deliver fuel to your engine, and they can become clogged over time. During a tune-up, the mechanic will use an injector cleaner to flush any particles out of the fuel injection system.

7. Adjust Valves

Your valves help prevent engine knocking or misfiring, which can reduce fuel economy. An auto tune-up will look for any issues such as worn valve stems or leaking valves, and adjust them as needed.

You should get a tune-up when your vehicle’s average MPG decreases by 10% or more, according to Car Pro Club. A tune-up will check spark plugs, ignition wires, air filters, fuel filters, distributor caps, and valves for wear and tear. If it’s been a while since your car has had a tune-up, consider scheduling one with Myers Automotive today.
