First post. First of all I want to say thank you for this forum. I have read through a lot of posts, both entertaining and informative.

I am currently test driving a '91 2 door XJ, that will be my daily driver for a few years, then it will get chopped. This was perviously a "government" vehicle, and I am not sure how well they kept up on the maintenance.

Jeep has 111k on it. So my question is about what maintenance should I immediately do besided the obvious like an oil and filter change? Differential fluid, etc.? I will probably change the plugs and wires because my experience has been that people have a tendency to leave them in forever. Is there anything mechanical that this year of Jeep is "known for?"

Owned a '93 XJ years ago that I loved. I would still have to this day if my ex hadn't traded it in for an F150. I owned it, she didn't ask, just thought I needed a "better" vehicle. Just one of the reasons she is now my "ex".

 

New Champion copper plugs gapped to .035

New distributor cap, rotor, plug wires

Check and replace air filter if necessary

Inspect and replace serpentine belt if over 60k. Go with a Goodyear Gatorback

Cooling system maintenance is important. Flush and fill, new 195 degree thermostat, replace old hoses.

New fluids including oil, transmission fluid, differentials, transfer case, and coolant as I already mentioned.
