diri sa Pinas, what constitutes a car tune-up?

nagpa-tune up ko gahapon ba, sa kilid2x lang nga shop hehe

nya ang gibuhat ra kay limpyo sa spark plugs, change sa aircon belt ug adjust gamay sa menor.. tagaktak na dayun aku 350

peru bsan ug wala pa tong problema sa akung aircon belt, 350 mn gihapn pangayu kay dili mn jd unta na apil sa tune up, na-timingan lang nga ilisdanan

so after atu, nag-wonder ko kung unsa jd apil aning tune-up diri sa ato-a sa pinas?

unsay kalahian sa tune up between sa CASA ug sa kilid2x nga shops?

ty daan mga bossing!

hehe.. wa koy car boss pero engun ane jd dw ang tune up boss ae

y tune-up today should start with a battery of performance checks to base line or confirm the engine's overall condition. These should include:

Battery voltage (very important with all of today's onboard electronics). Charging voltage.
Power balance or dynamic compression (to identify any mechanical problems such as leaky exhaust valves, worn rings, bad head gasket, bad cam, etc. that could adversely affect compression and engine performance)
Engine vacuum (to detect air leaks as well as exhaust restrictions) Operation of the fuel feedback control loop (to confirm that the system goes into closed loop operation when the engine warms up)
Scan for fault codes (to verify no fault codes are present, or to retrieve any codes that may be present so they can be diagnosed and eliminated) Check exhaust emissions (this should be a must in any area that has an emissions testing program to confirm the vehicle's ability to meet the applicable clean air standards, and to detect gross fuel, ignition or emission problems that require attention)
Verify idle speed (should be checked even if computer controlled to detect possible ISC motor problems); Idle mixture (older carbureted engines only, but injector dwell can be checked on newer vehicles to confirm proper feedback fuel control)
Check ignition timing -- if possible (should be checked even if it is not adjustable to detect possible computer or sensor problems) Operation of the EGR valve.
In addition to these performance checks, hoses and belts should be visually inspected. All fluids (oil, coolant, automatic transmission fluid, power steering fluid and brake fluid) should also be inspected to make sure all are at the proper level, and that the appearance and condition of each is acceptable. There should be no sludge in the oil, the ATF should not smell like burnt toast, the coolant should have the proper concentration of antifreeze and not be full of rust or sediment, the brake fluid should be clear and not full of muck, etc.

What to Replace

If the tune-up checks find no major faults, the following items should be replaced for preventive maintenance:

Spark plugs (gapped to the correct specs, of course). Consider long life plugs on applications where plug accessibility is difficult or where longer service life may be beneficial
Rotor and/or distributor cap (if required)
Fuel filter; Air filter; PCV valve and breather filter Other parts on an "as needed" basis (things like spark plug wires, belts, hoses, fluids, etc.)
Check and adjust (if required on older vehicles) ignition timing, idle speed and idle mixture; O2 sensor(s).
