My 99 SE has just turned over 107,000 miles. I want to get at least 180,000.
Besides basic maintenance, what should I be thinking about replacing?
Thanks, JH2000

Trans fluid, coolant, power steering fluid, brake fluid, fuel filter, plugs, check wires.

When you do the transmission fluid, take it to a shop where they will do a transmission fluid FLUSH then change the filter & gasket after the flush.

Keep an eye on the water pump and the harmonic balancer.

All of the above. The only things that I would add would be that when you replace(flush) the old coolant out and replace it with new(Dex Cool) to replace the thermostat with a 180 degree unit. Also, if you're still on your original O2 sensor, it would be a good idea to replace that as well. Welcome to the Century Club.

Ditto on what the old guy said about the O2. They're usually getting weak at about 50-60k.

wires plugs in mostly are always changed at 100mile

Most stock AC Delco wires won't even make it that long. Mine went at 80k.

THE BEST THING I CAN TELYOU IS TO CHECK WITH YOUR LOCAL DEALER VERY KNOWLEGDEABLE PEEPS THERE BUT EVERY THING THAT WAS LISTED IN OTHER POSTS WILL BE ON THE LIST

OLD GUY?

I resemble that remark!!!
