Hey everyone. I've been a lurker for some time, but I've been busy with other things, so I'm out of the loop. I'm hoping that you guys can help me decide what's best for my new-to-me 89 Jeep Cherokee. It has the 4.0l I6, auto transmission and 4wd.
As mentioned, the XJ has over 300k miles on it. It actually isn't running right now due to a leaky radiator (hopefully it's under warantee), but as soon as it is, I will take it for a long test drive to see how it runs. The P.O. said she didn't have any huge problems with it.
I'm thinking that it would be a good idea to start with the cleanest slate possible with this vehicle. I plan to, at very least, change the air filter, oil/filter, spark plugs, cap and rotor, and fuel filter. I also plan to begin Auto-RX treatments (although they'll probably take a while to complete). I think I'll pull the valve cover and see what it looks like under there (should I look in to adjusting the valves?).
I also think that getting fresh fluid (perhaps with some Auto-RX/LC?) in to the differentials, transmission, and transfer case would be a good idea. Then again, I'm not sure if this would cause more harm than it would help. I'm hoping that there are some dino fluids (read: inexpensive) that I could use and get good results.
I've tried wading through the search results (and I'll continue after I post this), but I can't find many threads with vehicles over 300k. That, and I'm lazy.
Any and all help is greatly appreciated. Also, any general advice is also encouraged, through PM if you don't want to steer the thread off topic. Thanks everyone!!!
