What parts do I need for a tine up on a 2003 Nissan Altima?

Hi there,

As your vehicle is fuel injected, the engine computer will take care of timing and air/fuel mixture etc.

The main components I recommend you consider changing for general engine tune-up are:
COMPULSORY

- Standard spark plugs (every 20,000km); Platinum spark plugs (every 50,000km)
- Air Cleaner/Filter (every 40,000km)
- Fuel filter (every 60,000km) - very important to keep fuel system/injectors clean
- Engine oil - at least "M" grade or better (every 10,000km)
- Engine oil FILTER (every 10,000km - same time as engine oil change, to prevent contamination)

Automatic Transmission

- Trans fluid - MUST use special NISSAN fluid only (Note: disregard manufacturer's interval - should be changed every 50,000km to prolong life).
- Trans Filter (change every 50,000km with trans fluid change, to prevent contamination)


OPTIONAL

- Injector cleaner additive (add to fuel tank every 40,000km) to keep injectors clean.
- Have your Onboard Diagnostics (OBDII) checked for any fault codes - inspect appropriate circuits for faulty components.


Good luck...

New Plugs, New wires if they are over 5 years old or you see cracking on the outer insulation, a new PCV valve (It's located on the valve cover), check the air filter to make sure it is clean (replace if it isn't) and finally, there is a sponge filter that goes to the air cleaner in some vehicles it goes where that line connected to the PCV valve line, check it and replace if it is gummed up.

Tune ups are always tricky because each model and year has a different itemized list, but these are the things I like to recommend;

Plugs
Wires
Cap and Rotor (if applicable)
Air Filter
PCV
O^2 sensors
Belts (inspect and replace as needed)
Hoses (inspect and replace as needed)
Oil and Oil Filter
Timing Belt and Water Pump (if applicable)
test coolant, brake fluid, and transmission fluid and replace as needed.

• Plugs - every two years for the single fire plugs up to 90,000 miles for the split fires etc.
• Wires - every two years on up depending on quality of wires.
• fuel filter - every 15,000 miles or so.
• air filter - as needed but every 10,000 miles or so.
• antifreeze flush - 30,000 miles for green, 75,000 for organic (Dex-Cool style)
• transmission fluid flush - every 40,000 miles.
• transmission gasket and filter change - every 100,000 miles.
• timing belt - every 100,000 miles.
• Rotate the tires every 6,000 miles or so.
