What is typically done when your car gets a 'tune up'?

Answer 1

i am an manager at advance auto,so i get alot of this asked.
a basic tune up is spark plugs,plug wires,dist.cap, rotor button,check all your fluids and rotate your tires
now you will be asked if you want a new air filter,an oil change,fuel filter change,or any new tires.
a tune-up can run you from 40-50 bucks or i have seen them amount to 4 or 500 easy depending on the car,heaven forbid you have direct-injection that stuff is EXPENSIVE!
but ina nutshell a tune-up is really replacing the stuff that helps the spark or what we call fire in an engine.
just remember only 2 things an engine needs to run that fire or fuel,and a tune up keeps the fire going

Answer 2

On a modern car, there's not much to do besides change the spark plugs and maybe the wires. The other directions tend to be just inspecting parts - checking the belts for wear, the hoses for cracks, etc. Normally fluid and filter changes are separate.

If you have something from the mid '70s or earlier, a tune up will mean a lot more. The breaker points in the distributor will need filing or replacing, then the mechanic will have to set the ignition dwell and timing. The carburetor has a few adjustment screws to check, too. And the spark plugs and wires still need changing occasionally. Tune ups were a fair amount of work back then. But modern cars don't have carburetors or points, and often don't have distributors either.

The term "tune up" can mean different things to different people but, in most respectable shops it is changing the ignition system parts that are designed to wear out, such as plug wires, plugs, rotor, cap, pcv valve, and perhaps cleaning the fuel delivery system, changing filters, and then checking the fuel-air mixture and other adjustments to fine-tune. Depending on the age and make of your vehicle it may or may not have all of the items listed. Most all cars now have some sort of on-board diagnostics and should be scanned with the proper equipment to make sure no codes or faults exist.

Answer 4

Never i repeat never go get a "tune up" go get your oil changed and have them check your belts and filters when they do.. then have someone you know and trust change them for you ( $30 and hr is way to much to pay for this) and if you need spark plugs just go ask for them to be changed.. a "Tune Up" is a rip off that charges you to look at what you might need then charge you more for it IE spark plug wires...and they rarely go bad

Answer 5

a tune up is the replacement of the components of the secondary ignition system spark plugs,plug wires,distributor cap and rotor.a complete tune up also includes an oil change(officially.) it should also include any minor adjustments. idle speed. timing. if applicable

Answer 6

a tune up is an upgrading. rather than the other persons answer which to me looks more like a check-up/maintainence/mot stuff

Answer 7

Replace the plugs, distributor cap and rotor(if you have them) and check the timing with a timing light.That's it and for that they charge $50 or more.They may make it sound like they do more like checking your tire pressure and tissue dispenser velocity. but it's just added things that aren't anything you cant do yourself and save money.

Answer 8

oil change/filter

new air filter

tire rotation
thats basic

this is extra

Answer 9

If its just your engine, they check and/or change all the fluids,
But a full sort of a service, they would do that and rotate tyres change brake pads. brake pads
