Timing Chain or Belt Wrangler 4 cyl.?

I have a 97 Wrangler with a four cylinder. Does anyone know if it has a timing chain or a belt? I believe it is a 2.5L. Is that right? This is my first Jeep and I am clueless.

It uses a steel timing chain so no worries about needing to change it on a regular basis like if it had a rubber timing belt.

Looks easy as pie to change, whats the maintenence schedule say? like 100km's or something?

Looks like you just gotta pop off that open idler pully and remove the cap and your there. One thing I like about the 4cyl is the amount of room under the under the hood.. Im thinking of putting a 5th seat in there, lol

You're confusing the serpentine belt which does nothing but drive the waterpump, fan, alternator, and a/c compressor. He was asking about the timing chain whose job is to turn the camshaft. You can't see the timing chain, it's under a cover.

No im not, I said to get at the timing chain you pull that idler pulley (for the serpentine) and remove the cap (or cover) and your at the timing chain.. The cover is held on with 3 screws.. really easy to access..

im not completely inept,

For the search value of this thread. The 2003+ 2.4L uses a timing belt not chain as with other TJ motors.

Are you sure? I dont have a FSM for the 06, but I do have one for the 2003 and I was almost positive I read that it was a chain. It even showed a picutre with a marked link.

Ive been wrong before tho (many times). So if it is indeed a belt, how often is it supposed to be changed?

The 2003 thru 2006 2.4L motor has a rubber timing belt.
I'm not exactly sure of the replacement schedule but it's around 100,000 miles.
Judging from how accessable the front of the 2.4L motor is, changing the timing belt should be pretty simple.
Thanks.

So to be 100% clear.....and I am only asking because I am about to inherit a 1995 2.4L Wrangler with 114 on the OD.... pre-2003 the 2.4L had timing chains? How long are timing chains good for?

Let's not get confused here, the 2.4L engine currently shipping in new TJs is nothing like the 2.5L engine in that 1995 Wrangler. Make sure you realize what you have is a 2.5L engine which does use a timing chain.

Sorry for the confusion (ignorance) on my part. Got it. 2.5L . . . . how long are timing chains normally good for? It had a "major tune-up" about 5k miles ago where the serpentine belt among other things was changed.
