A regular maintenance function, usually associated with the replacement and adjustment of parts and components in the electrical and fuel systems of a car for the purpose of attaining optimum performance.

How to Tune Up a Car

Your car should receive a tune-up (often referred to as a "major service") every two years or 30,000 miles, whichever comes first. Here's what needs to be done.


1. Replace the fuel filter. If you have a fuel-injection system, regular cleaning isn't necessary unless the injectors are clogged.

2. Change the spark plugs (unless they're platinum, in which case you have 30,000 more miles to go). Also examine the spark plug wires and replace as needed. A new set of high-quality wires is worth the cost. They may be permanently attached to the distributor cap, so it will have to be changed as well.

3. Replace the distributor cap and rotor if your car has them (some newer models with distributorless ignition don't).

4. Change the points and condenser if you have an older car (roughly pre-1978) that doesn't feature electronic ignition. You'll actually want your points changed, or at least adjusted, every six months or so (if they're changed, check the ignition timing as well).

5. Check the ignition timing and adjust as needed (rare for a car with electronic ignition - post-1980 - and some cars don't allow this at all).

6. Adjust the valves as needed (unless your car has hydraulic valves). Be sure to replace the valve-cover gasket as well, especially if you see oil on top of your engine.

7. Check the belts. Replace if worn.

8. Check the fluids under the hood and replenish as necessary. Change the oil and oil filter if it's been 3,000 miles since the last oil change.

9. Replace the air filter, which should be changed between major services - every 15,000 miles - as well.

10. Adjust the clutch, if you have a manual transmission (although some cars now sport self-adjusting clutches).

11. Service the battery, adding distilled water (if required), cleaning terminals and cable ends.

12. Replace the PCV (positive crankcase ventilation) valve. It can make your car run rough or stall if it gets clogged, and it's cheap and easy to replace.


A tune-up isn't a cure all, but when done regularly, it can prevent a host of expensive problems.
