Tune-Up
What Is a Tune-Up?
The term “tune-up” has evolved significantly since it was first used in the early days of the automobile. Originally, a tune-up referred to the process of adjusting and replacing key parts of a vehicle’s ignition and fuel systems to ensure everything ran in harmony. This included replacing breaker points and the condenser, installing a new distributor cap, rotor, and spark plugs, setting the ignition timing, and fine-tuning the carburetor. Much like tuning a musical instrument, this process ensured that the ignition and fueling systems worked together precisely for optimal performance—hence the name “tune-up.”
For older vehicles, tune-ups were a routine necessity. Even as electronic ignition systems replaced the older points-style systems, there was still a need to replace spark plugs, distributor caps, rotors, and adjust the carburetor. However, with the advent of distributorless ignition systems (DIS) and computer-controlled fuel injection, many of these traditional tune-up tasks have become obsolete. Today, modern engines rely on advanced engine computers and sensors to constantly adjust and maintain performance automatically.
Nowadays, the term “tune-up” is more of a legacy phrase. It’s generally used to describe a collection of routine maintenance tasks that help keep a vehicle running smoothly. At Minit-Tune and Brake, “tune-ups” can extend the life of your car and ensure it performs efficiently. Most owner’s manuals include guidance on when to perform these maintenance checks.
A modern tune-up can involve a variety of inspections and replacements. These may include checking filters, belts, hoses, and fluids. If you’re unsure when your spark plugs, ignition wires, or coil boots were last replaced, it might be time to have them checked at your closest Minit-Tune and Brake location. While some components may still be in good condition, examining them can help catch small issues before they turn into major repairs.
Refer to the list below for the parts and systems commonly inspected or replaced during a tune-up. You may not need to service all of them every time, but it’s wise to ensure they’re all functioning properly.
Performing regular tune-ups is one of the best ways to maintain your vehicle’s original performance. A car that’s out of tune can suffer from poor fuel economy and sluggish engine response. Correcting those issues can often deliver a noticeable improvement. Keeping your vehicle in peak condition today can help you avoid expensive repairs down the road.
Minit-Tune’s tune-up guide outlines the most commonly serviced components during a tune-up, including spark plugs, plug wires, the air filter, and fuel filter. It’s also a great opportunity to check under-the-hood items like belts, hoses, and fluid levels.
What Does a Tune-Up Consist Of?
Spark Plugs
- Spark plugs wear out over time and can cause misfires or rough running.
- Replace them with the type recommended by your vehicle’s manufacturer (check your owner’s manual).
- Use a small amount of anti-seize on the threads and avoid getting it on the tip.
- For modern engines, use Double Platinum or Iridium plugs if required.
Ignition Wires & Coil Boots
- Over time, plug wires and coil boots can break down, leading to poor performance, rough idling, or misfires.
- Replace them if worn, and use dielectric grease in the boots to prevent arcing and ease removal in the future.
Ignition Coils
- Ignition coils convert battery voltage into the high voltage needed for spark.
- Faulty coils can cause misfires, poor fuel economy, and sluggish acceleration.
- Some vehicles use coil packs; others have coil-on-plug setups – check your specific engine type.
Distributor Cap, Rotor & Breaker Points (if equipped)
- Older vehicles may have a distributor cap and rotor that wear with use.
- Always replace the cap and rotor together.
- Move wires one at a time to avoid incorrect firing order.
- Very old vehicles (pre-1974) may use breaker points that require periodic replacement or adjustment.
Engine Air Filter
- Filters dust and debris from the air going into your engine.
- A clogged filter can reduce performance and, on carbureted engines, fuel economy.
Cabin Air Filter
- Keeps air inside the vehicle clean by trapping dust, pollen, and pollutants.
- A dirty filter can restrict airflow and lower HVAC efficiency.
Oil Filter
- Removes contaminants from engine oil to protect internal components.
- Replace it at every oil change for optimal results.
Fuel Filter
- Filters impurities from gasoline before it reaches the engine.
- A clogged filter can lead to hesitation, rough idling, or even damage the fuel pump.
- Replace as recommended by your vehicle’s maintenance schedule.
PCV Valve (Positive Crankcase Ventilation)
- Regulates pressure in the engine crankcase.
- A clogged PCV valve can cause oil consumption, misfires, and internal pressure buildup.
Serpentine Belt
- Powers engine accessories like the alternator, water pump, and power steering.
- Inspect for cracking, fraying, glazing, or wear. Replace if any damage is found.
Belt Tensioner
- Maintains proper tension on the serpentine belt.
- A worn or sticky tensioner can shorten belt life or damage accessories.
- Check for smooth movement and strong tension.
Timing Belt (if equipped)
- Synchronizes the engine’s internal components.
- Failure can cause severe engine damage. Some vehicles use timing chains instead, which last longer but still require occasional inspection.
Radiator & Heater Hoses
- Carry coolant through the engine and HVAC system.
- Inspect for bulging, cracking, leaks, or spongy spots.
- Weak hoses can burst and cause engine overheating.
Engine Oil
- Lubricates engine parts and prevents wear.
- Change at regular intervals based on mileage or time – refer to your manual.
- Always replace the oil filter when changing the oil.
Coolant (Antifreeze)
- Regulates engine temperature and prevents freezing.
- Over time, coolant breaks down and loses its protective qualities.
- Flush and refill at intervals specified in your manual. Use the correct type for your vehicle.
Brake Fluid
- Transfers pressure from the brake pedal to the brake calipers.
- Absorbs moisture over time, reducing performance and causing corrosion.
Automatic Transmission Fluid (ATF)
- Cools and lubricates the transmission.
- Check fluid condition—if it’s dark or smells burnt, it may be time for service.
Power Steering Fluid
- Ensures smooth and responsive steering.
- Should be clean and within recommended levels.
- Replace if it looks dark, dirty, or if steering feels heavy or noisy.
