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 have additional services needed.
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. They will also likely top off the brake fluid in your vehicle (as well as any other fluids that are low).
The AC in your vehicle runs not only off the coolant but there are a number of smaller features connected on the vehicle that help the AC function (unlike the heat, which is taken off the engine block, the vehicle must produce cool air, so you essentially have a portable AC unit built into the car). During the system check the mechanic will look into the individual parts to see if something is not working correctly. They may suggest a coolant flush as well (especially if you have an older vehicle).
The electrical system can be inspected both visually and through the car’s computer system. The car will log error codes when something goes wrong. 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. They will also perform an inspection of the electrical system. This includes looking at the tail lights, brake lights, bulbs over your license plate, and other problems you might have (and not know about).
