Hey guys, i have been lurking around this forum here for about a week and a half checking everything out. I must say there is a bunch of great info on this site. I just have a few noob questions about the 4.0.
First off I bought a 99 XJ Sport (White) 4dr 4.0 4x4. It is all stock and hope to get some pics uploaded here soon. It was actually fleet vehicle for a wireless company here in MN so I would imagine the service has been done routinely (i hope). Last weekend I did the spark plugs and wires and changed the oil and put in a K&N air filter (planning on getting a cold air intake in the future). The coolant looks pretty new, it is a nice bright green as the tranny fluid is clean as well.
1. What is typical oil pressure the 4.0 runs at? Mine runs right at 40 and just a little over when going down the highway. Is that normal?
2. The temp guage sits at 210 and doesnt get any hotter, is that the normal temp?
3. Is there anything I should be looking for underneath the vehicle on the 4wd system to make sure everything is okay? I would hate for some thing to happen to that!
This is not my DD, though i did drive it to work today, it is just better to drive than my 96 cutlass . Sorry for the long post.
yes that is normal oil pressure. The normal operating temperature for the 4.0L is 210.
And if you crawl underneath just check that the transfer case and both axles are full. It also wouldn't hurt to put a little lube on the transfer case shift linkage too. Maybe check your u-joints
Thanks for the info and quick replies so far. Like I said, I am a complete noob on this stuff so i am sorry my questions are so lame, but I guess that is how you learn. Is it easy to change the fluids in the diffs and the txfr case? I have the access to all the tools I need, my father in law is a mechanic and has everything including a hoist.
Is your battery original? If it is getting week or has dead cells it will give you some strange problems.
Thanks, yeah from looking in your profile we do have the same one (my bumpers are even white too. I am not sure if I like it yet though, they might turn Black. My power windows do work from all locations for now. I have seen some threads on that so i am watching those. I dont have the stock fog lights installed, they must not have picked that option. My battery looks as it was replaced in March of 06, but is a stock Mopar battery. It seems to be holding up well for now as well.
There is 130k on er. I have heard so many good things on these engines I wasn't to worried about it. I have a few buddies with the 97 XJ and they have had great luckk as my Dad also has a 95 XJ 2dr that is running like a top as well. I'll get some pics when I get home from work and throw them up on Photobucket. I should really just upgrade my account so I can just post pics in the forum since I know I will be on this site a bit.
Check your hard brake lines - the one going from the MC to the RF caliper let go on me last Saturday morning - it had rusted up pretty well and just blew out. Lucky for the Honda Fit in front of me I was able to get 'er stopped with the e-brake. It let loose at the 90 degree bend at the bottom of the run by the inner fender.
BOTH of the front hard brake lines were rusted - so I replaced them both - easy job and well worth doing for the peace of mind. I flushed my brake system while I was at it -
Curious, but the hard lines going to the back brakes were fine ...
They seem to be really durable vehicles. I bought a '98 XJ last September with 42,000 on the clock, have about 57,000 on it as of this morning - other than the brake lines the only thing I've done was to replace the original battery. (well, I've done 5 oil changes as well) -
Not to hijack the thread, but quick question on this. I just got a 2000 XJ Sport and the rear driver window does not go down from the driver door. However, if you use the switch on the rear passenger door, the window will go down, and THEN you can use the switch on the driver door. As soon as the engine is turned off and back on, you have to repeat the process. Also, same location, the rear passenger door does not lock or unlock with the power lock button, OR the remote key fob. What am I lookin' at here? Rusted harness connector? Bad wiring?
