For your vehicle to run its very best, and to identify potential performance problems down the line, it is important for you to know the answer to, "what is a car tune-up?" and how it helps extend the life of your vehicle.

What Systems Are Checked during a Car Tune-Up?

When looking into "what is a car tune up?" you’ll probably have more than a few parts replaced. The mechanic will also perform a number of system checks. The checks are usually included with the price of the car tune up, but if the individual systems need attention, then you may incur additional costs.


Tire and Brake Inspection


This is a straight-forward system inspection. The mechanic will look at the tread and suggest if you should replace the tires now or if you can run on the tires for longer. The mechanic may also rotate the tires to keep the wear on the rubber the same.


Brake inspections will also be performed. The mechanic will look at the thickness of the brake pads and make brake replacement suggestions. 


Air-Conditioning System


The air conditioning system in your vehicle is dependent upon freon. During a tune-up, a pressure check of the lines may be performed. The mechanic will also look into the individual parts to make sure everything is working properly. 


Electrical System


The electrical system can be inspected both visually and through the car’s computer system. The car will log error codes when something is malfunctioning.


When the mechanic connects their computer to the vehicle they can download the error codes and find out if there are any electrical system issues going on.


During this process they will also perform an inspection of the electrical system by inspecting all the exterior lights.

If you take your vehicle into the dealership, they will also have all of this information. 

Additional Vehicle Maintenance

Beyond your tune-up, there are a number of other routine forms of maintenance you need to perform in order to keep the vehicle running correctly. These include an oil change.


When you have your oil changed, you should also have the oil filter changed. Your owner’s manual will provide you with the parameters for how often you should have the oil changed on your specific vehicle.


While many drive-through oil change facilities will provide you with a basic mileage sticker, this is a standard number that may not be accurate for your car. Always consult your owner’s manual for maintenance schedules and concerns regarding your vehicle.

Keep Vehicle Records

Now that you know the answer to, "what is a car tune-up?" and what to expect during the tune-up, you’ll want be sure to save all of your maintenance and repair records. These records will indicate what was changed and also what to keep an eye on in the coming months.

Secondly, when you take your vehicle into a mechanic the following year, you’ll already know what items don't need serviced if they were serviced during a prior service appointment. 


Things like spark plugs can quickly add up in costs. So keep these papers on hand and, when the mechanic gives you the repair suggestions, make sure to look over the previous year’s changes so you know what can be omitted from your current year's tune-up.
