100k Tune Up

I just rolled 90k on my 02 Impala Base. I know the car should have a turn up around 100k miles. What are some other things that need attention at that time?

I have had new fuel filter, serpentine belt, brakes, and new brakes installed. I had a new LIM gasket installed @ 68k (at my cost), why is it Chevy dealers won't acknowledge the 3.4 gasket sucks.

Anyway, what items would need to be replaced at tune up time?

-plugs?
-wires?
-air filter?
-tranny flush?
-power steering flush?
-struts?

Just trying to guage what I need and the approximate costs involved. I figured I'd ask this forum, instead of a dealer or mechanic (they might tell me I need more).

Thanks, Tom

Struts as necessary, no uneven tire wear or bounciness, not necessary. Delco plats and wires are recommended. No trans flush, just the normal service. Maybe another fuel filter, AF as necessary per inspection. Any mushy hoses should go.

Air filter for sure. Trany flush not a bad idea if you haven't done one previously AND if your fluid is cloudy, smells burnt, or you see metal filings on the tip of a magnetized dip stick. New wires if you haven't changed them before - especially if you live in the North. Don't forget to spray them with silicone lubricant.

The jury is out on plugs. Some say, "yes" and some say, "no." Pull them out and look at them. If they are reasonably clean and not worn, check their gap and put 'em back in.

Unless you are having a specific problem don't do the power steering flush or replace the struts. You can check your rear shock absorbers - they're probably OK (note shock absorbers and struts are different).

I think the two big items you should consider are tires and a battery - again especially if you live in the snow-belt. Speaking of belts, I don't change my "fan" belt but I always carry a spare in the trunk in vehicles that hit the 100K mark. It wouldn't be a bad idea to inspect the radiator hoses just in case one is getting to look and feel worn out.

Do the usual stuff like make sure you check the antifreeze. You can get a tester for under $5 at Wal-Mart. Buy a cheap grease gun and squirt the grease zirks on your suspension. If you don't need tires at least check the air pressure and replace any missing valve stem caps.

The last thing you might want to do is check your air conditioning refrigerant. Chat with your parts guy he can get you outfitted. They usually sell cheap kits to refill AC units. The kit will have some hoses, a pressure gauge, and a fitting in it. Don’t buy the refrigerant or AC pump oil until you know you need ‘em.

per the manual

INSPECT spark plug wires
REPLACE spark plugs
Automatic Tranny fluid and filter

And here I am wondering what things I'll need to check at 200k... I'm still disturbed at the original parts I find that I had expected to wear out long long time ago. (Ball-Joint for example)... I'm sure I could use a new set of plugs, wires, hoses, belts... but i'm more a 'lets wait for it to break' person.

Thanks for the INFO. It looks like I have had new stuff already done so far.

-Fuel Filter
-Tires
-Battery
-Serp. Belt
-Brakes/Tires.

So all I need is plugs/wires/tranny service. Radiator was flushed at time of new LIM gasket, hoses were changed then also.

The car will be ready for 200k!

Thanks to all for the info!
