In the not-too-distant past, vehicle owners often spoke about giving their vehicle a much needed “tune up”.  The term “tune up” has a different meaning today, but it is still an important maintenance function that should not be overlooked.

In this month’s blog, we examine the modern “tune up”, share its purpose, and what is involved with this service.  If you have not had your vehicle in to get a tune-up, we highly recommend it to increase the longevity and function of your vehicle.

What is a tune up?

A vehicle tune up may include a variety of services, depending on where you take your vehicle for maintenance.  As the mechanical components of the vehicle have evolved over time, the term tune up has changed.  But the essential focus of any tune up is to service the ignition system, specifically the spark plugs.

Your vehicle’s combustion engine is powered by a fuel source that when ignited, creates the energy to control the many functions of driving.  Spark plugs are a critical component of the ignition system that create and deliver the electrical current for your internal combustion engine to operate.  When those spark plugs are worn, or unable to produce enough current to create the ignition, your engine may misfire during starting, stall more often, be sluggish or unresponsive, or not start at all.  You may also notice a reduction in your overall fuel economy.

What’s included in a tune up?

The two important services within a tune up of the ignition system include:

  • A thorough check of the engine spark plugs. If there are issues with a fouled spark plug, replacing them is the proper approach.  At the same time, the spark plug wires should be checked for wear and damage and if necessary, be repaired or replaced.
  • Adjustment or correction of the spark plug timing. Timing is everything when it comes to spark plugs, and when timing is off, will cause many of the above noted issues with your vehicle’s engine and ignition system.

Today’s modern definition of a tune up goes beyond checking the spark plugs and ignition system.  A full vehicle tune up should also include:

  • Scanning the Onboard Diagnostic System of newer vehicles for possible problems within the engine. The service technician uses a device that is connected to the vehicle to do a read-out of any errors or codes that may indicate failure in critical engine components.  These diagnostics vary by each vehicle but can help pinpoint issues for a service professional.
  • Changing the engine air and fuel filters to ensure that the engine is receiving clean air on intake. Air is a vital component within the combustion process and dirty or clogged filters will result in lower vehicle performance.
  • Checking the PCV (Positive Crankcase Ventilation) valve for carbon buildup. This is another important component that helps the air/fuel mixture to avoid the engine from running too rich.
  • If you are not already on a regular maintenance for other considerations like belts, hoses, and other engine fluids, it’s a good time to have these completed during your vehicle tune up.

The next time you think of a tune up for your vehicle, remember that this important service has changed over time due to the modernization of vehicle systems.  However, the core components of any tune up are still critical to your vehicle.
