We often use words without regard to their meaning. Take the term “tune-up,” for example. 

What does that mean when someone says they’re bringing their car in for a tune-up? What repair work does that entail? 

And, more importantly, how do you know if your car needs a tune-up? An important question if you hope to keep your car in good operating condition for many years. 

What tune-up really means

A car is a mechanical object with tens of thousands of working parts all melded together to create a modern vehicle. 

Cars are designed to provide warning signs if something isn’t working correctly. That’s where odors and noises and visual warnings provide signals. Pay attention, and you can catch a minor issue before it escalates into a bigger, more significant problem. 

A tune-up generally refers to a series of maintenance tasks performed to ensure it’s running smoothly and efficiently. This can change by manufacturer and model, but in general will include replacing spark plugs, checking and adjusting ignition timing, inspecting and possibly replacing filters, inspecting and possibly replacing ignition components, and inspecting and topping off fluids. A mechanic will assess the overall condition of the engine and all of its related components. 

Do this regularly to ensure performance. You’ll also improve fuel efficiency and overall reliability. 

Is it time to schedule a tune-up for your car?

How do you know if it’s time for a tune-up?

Remember those warning signs we spoke of in the previous section? This is where it helps to pay attention to how your car is operating. Just a few seconds to check in with your vehicle can alert you to realizing it’s time to schedule a tune-up. Watch for:

Decreased fuel efficiency – you do check your mileage every time you fill up, don’t you? This simple step will alert you to decreasing fuel efficiency. It’s easy to do. All you need is to track how much fuel is consumed and the distance traveled. Divide the number of miles traveled by the amount of fuel consumed. Then think back to how you drove on this tank of gas. More city miles than usual? Unusual driving conditions? If nothing changes from tank to tank, and your mileage consistently decreases, it’s time for a tune-up.   

Poor performance – you can feel it when your car isn’t performing well. It may feel sluggish or lack power when accelerating. It might hesitate or stumble. It may need a tune-up, or it may need something else. In any case, bringing it in for inspection early is the best way to ensure your vehicle remains well-maintained. 

Rough idle – when you turn the car on and leave it in park, does it rumble like an old truck? Do you stop for a minute thinking it’s not going to remain on? A rough idle could indicate a problem with spark plugs, ignition components, or fuel delivery. All problems a tune-up will catch and address. 

Misfiring – a rough idle can be concerning; so too can misfiring. Misfiring occurs when one or more cylinders in the engine fail to ignite properly. This gives you a noticeable jerking or shaking sensation while driving. 

Hard starting – on those cold winter mornings, you might notice your car has trouble starting. You know it’s not your battery – that’s when it might have something to do with performance. Those spark plugs, ignition, or fuel delivery system are sputtering and need a little work to ensure optimal performance. 

Emissions – ever failed an emissions test? Or maybe you’ve noticed white smoke coming from the tailpipe? This is a clear indicator of an engine that is not running efficiently, and is in need of a tune-up. 

Check engine light – sometimes it might seem like your dashboard lights up like a Christmas tree. Maybe some of the lights stay on and when you check them, they seem like they aren’t a big deal. Dashboard lights are alerting you something is off – the sooner you fix it, the better chance of it remaining a minor issue. The check engine light can illuminate for many reasons – some more critical than others. Because you don’t know without an inspection, you should schedule one as soon as possible. It’s the best way to ensure the vehicle is properly tuned and running well. 

What does a mechanic do in a vehicle tune-up?

When you bring in a car for a tune-up, it starts with a series of questions. As mechanics, we want to learn more about what brings you in. What are you noticing? That can lead to pinpointing where we start inspecting, and gives us areas to focus on. Still, tune-ups do have a series of steps:

Inspecting and replacing spark plugs – over time, spark plugs can wear out or become damaged, leading to poor engine performance. We’ll inspect the spark plugs and replace them if necessary.

Checking ignition system components – this includes inspecting ignition coils, distributor caps, rotors, ignition wires, and other components to ensure they are functioning properly. Any worn or damaged parts may be replaced.

Inspecting and replacing filters – we’ll check and, if needed, replace the engine air filter, fuel filter, and possibly cabin air filter. 

Checking fluid levels and condition – this includes inspecting engine oil, coolant, transmission fluid, brake fluid, power steering fluid, and windshield washer fluid levels. We’ll change the fluid or top-off as needed.

Inspecting belts and hoses – we’ll inspect them for signs of wear, cracks, or other damage and replace them if necessary.

Checking and adjusting engine timing – we’ll check and adjust ignition timing and idle speed to optimize engine performance and fuel efficiency.

Inspecting and testing battery – we’ll test the battery’s voltage and charging system output and clean the battery terminals if needed.

Inspecting brakes – if warranted, we may inspect the brake system components, including brake pads, rotors, calipers, and brake fluid, to ensure they are in good condition.

Performing diagnostic tests – if the vehicle displays any warning lights or unusual symptoms, mechanics may perform diagnostic tests using specialized equipment to identify and address any issues.

All of it done to ensure you drive away in a car in optimal condition.
