Service?

Hello, this is my first post on a jeep forum!
I recently bought a 1997 wrangler with the 2.5L motor. It only had one owner and he kept in a garage so it is pretty clean. It has 150,000 on the odometer and I am just curious as to what fluids and filters should I change? Also what should I expect to break/ need replacing soon? I replaced the belt yesterday and have to order a new pressure unit but other than that it seems to be a pretty solid vehicle.
Thanks!

Unless the PO provided detailed and what looks like reliable maintenance/service records, I would do everything. Motor oil/filter, tranny fluid, TC fluid, diffs fluids. Coolant flush and fill. Brake fluid flush and bleed.
Check your brake pad/shoe and rotor/drum wear. Check U-joints.
Just off the top of my head, I'm sure I'm missing something...

If unknown, then ALL fluids. Fluids are the key to a long happy JEEP life. Just ask my 1980 CJ7 with 365k on the clock.

Serpentine or timing belt? Replace the timing belt if you don't know when it was replaced.

I replaced the serpentine belt, but it probably isn't a bad idea to do the timing belt also. I do not have any information on previous maintenance so I will go ahead and change all the fluids and filters. The rpms and oil pressure fluctuate a little bit, could this be happening due to the fact the oil pressure sending unit is leaking oil?

Oil pressure, yes. Not RPM's though.

My '04 FSM shows the 2.4L has a timing belt. But I'm about 98.5% sure the '97 2.5L has a timing chain based on these threads below. Look into that before you go by a timing belt.
If it's a chain don't worry about it unless you have timing problems or hear clanking.

Correct, but you are not forum supporter, so why should he take your word on it? LOL just kidding.
To the OP: Like the others said, do the basic maintenance and go from there.

Fluids, belts and hoses. I did this on mine. That way I knew the status of everything.

Thought of another... Spark plugs and air filter.
Basically, unless you have complete and reliable service records, as stated before, do everything and start your service intervals over.
