Recommended Preventive Maintenance

Hey all,

So I have had my 97 Sahara for a little over two years now and have been reacting to maintenance issues rather then being proactive. I have a steady paycheck now and have the means to begin taking care of it like it deserves, but I don't know what all I should be monitoring.

When it comes to mechanical skills I am no mechanic, but by asking more savvy relatives and reading/watching instructions I have figured out everything that I've attempted so far.

I'm looking for a list or guide to the basic level preventive maintenance every jeep owner should be doing. My jeep is mainly a stock 4.0L used as a DD with light trails tossed in when I can.

Thanks in advance.

The owners manual will have the basic fluid change and service intervals. I usually recommend to people who want to do there own work to get a all data diy It will give you a good reference for fluid change intervals, correct fluid types, and really good repair and diagnostic instructions. The last time that I purchased one vehicle from them it was under $10 per year.

In my opinion. It is another tool that you should have in your tool box.

Best of luck,

Preventive maint. is the key with any machine, Jeeps are no different. Like Jsuggs said, the owners manual has all the major info for intervals, fluid specs, etc you'll need. You can pick up a Haynes manual, for about $15 on ebay, that has all the detailed info you'll ever need, and in the event that you need more, between this forum (and others), a call to a local service section of a stealership (you'd be surprised how friendly mechanics can be if you just go down there and pick their brains), you will be covered. I am no mechanic, but short of tearing down an engine or tranny myself and rebuilding it, there's not much I haven't been able to figure out with some help. No doubt I could tackle those as well with proper planning and the right tools and some experienced help at my side. Short of exhaust manifold cracks, the I6 4.0 is one of the most solid engines I've ever seen, and I hear the same from mechanics and do it yourselfer's all over the place.

With something of that age that has a possibility/history of neglect I would start by replacing ALL fluids, including flushing the heater core, radiator, and block if you are inclined. I would check all high wear and consumable items such as ujoints, ball joints, bushings, connections, mounts, tune up with the works, O2 sensors, etc. I would get all of that up to snuff and then start routine maintenance like checking for wear, lubricating, and changing out fluids and worn parts as needed going forward.

I just went through most of my initial list I did when I bought a 150k mile '99 last winter. Probably cost me a total of $500 or so for all parts and fluids so far. Getting ready to start on the more expensive list now that I have deciding to keep this rig again. lol

Take care of machines and they will take care of you! Enjoy it!
