what should I expect to service/replace at 100k on my 97 accord lx except TB and water pump.

 

You should change all your belts and your spark plugs.

In fact, you should have changed your TB at 90K miles. It's only like $400 to change it. I've had friends who ignored and two of them had their timing belt shredded in their engine. For one of them, it cost $800 had a mom and pop shop and repair this, but it cost about $400 to tow the car from Palm Springs to LA.

Honda is a low maintenance car.

 

you don't need to "replace" anything...you just need to keep doing yourt scheduled maintenance..like huyvu said.. your timing belt is the most important thing, and that should have been done at 90k, also you feul and airl filter every 30k , which meant that thy should have been done at 90k....in short..look at the maintenace schedule that came with the manual for the car..if you do not have one get you can get one on ebay...nothing should be wrong with it if you kept up your maintenance...

 

Take a look at the 90k service info in your manual. Consider tranny service, radiator service, brakes, etc. Follow the manual, you'll be ok.
