'99 TJ 2.5l just hit 100k

Hello,

My '99 Wranlger 2.5l just hit 100k a few weeks ago and I'm wondering if there are any things I should start planning for. I already replaced my timing belt, idler pulleys, and water pump around 60k (along with a radiator I just re-replaced with an all-aluminum) I commute about 30 miles 4 times a week for school. I also do tons of trips around WV in the summer for hiking, kayaking, and camping.

Anything I should be on the lookout for? I've heard I a new oil pump is something I should do, but I haven't seen too much that says that is a requirement. I replace my oil + filter religiously. I've also done my distributor cap, rotor button, wires and plugs around 75k.

Let's hear what you have done to keep your Jeep running good!

-Alex

I think you're gonna be just fine...

i've got appx 105 on mine with pretty much the same maintenance and i've got zero issues...not even a hint of anything wrong.

99 2.5L doesn't have a timing belt. I hope you didn't pay some one for that!
I would flush and replace the brake fluid, that is something nobody does on schedule. Check the front knuckles for wear grooves from the brake pads and repair if needed. Give the throttle body and IAC a good cleaning.
I don't think the oil pump should be a problem for a long time so I wouldn't mess with that.

My original 2.5 lasted until 215k before it broke a piston skirt. (Over reved getting out in traffic) I've now got another 50k on the reman.

All I ever did was oil changes every 3-4k, the engine is pretty bulletproof.

I'd look into changing the fluids in the trans, transfer case, front and rear diff and power steering

If you have never replaced the fluids for the diffs, xfercase, and trans, now would be a perfect time.

Well I replaced whatever you call the belt that's in there

I actually have tons a fluid for the trans and differentials. There's gunk like they tried to leak and sealed themselves back up, so I may even do new gaskets on them too.

My engine has it's quirks, I tried to replace the TPS but the tiny torx bolt kept stripping all bits and I couldn't get it out. My idle is a bit funny.

Here's actually everything I've done:

New cat/muffler and o2 sensors
New plugs, wires, dist cap, rotor button
New belt, idler pulleys
New radiator (x2, all aluminum in there now)
New water pump

I keep my throttle body clean
Oil and filter every 3-4k, I use conventional and a little lucas oil stabilizer
Air filter replaced as needed

So for a spring project I'm thinking new gaskets and fluid in the diffs, new fluid in my trans and transfer case, and flushing out my brake fluid and power steering fluid.

I may even get the urge to do some painting underneath since I'll be spending so much time under there.
