What included in Engine Tune-up?

A tune-up usually refers to the routine servicing of the engine to meet the manufacturer’s specifications. Tune-ups are needed periodically as according to the manufacturer’s recommendations to ensure an automobile runs as expected. Modern vehicles now often run over 160,000 km (or 10 years) without requiring a tune-up.

Tune-ups may include the following:

* Re-fastening of cylinder head bolts
* Adjustment of the carburetor idle speed and the air-fuel mixture
* Inspection and possible replacement of ignition system components like contact breaker, distributor cap and rotor button
* Replacement of the air filter and other filters
* Inspection of emission controls
