    Looks like a good upgrade. Nothing will take the fun out of hitting the trails quicker than having to constantly watch a temperature gauge.

      I'd been putting this one off, assuming the closed system just needed to be well-maintained. That might be true, but I'm too damn lazy for the amount of maintenance it seems to need.

    Open Cooling System Conversion (Continued)

    It was a tight fit for the 4.0L open cooling system overflow bottle, so I opted to install one from the 2.5L model. This one fit neatly in the space next to the air intake box by moving the fuel pump ballast resistor, auxiliary fan relay, and EGR solenoid.

    Now, if only I could find a cap that fits!

    - 1988 XJ Base - I don't actually drive it. It just sits in the driveway while I throw parts at it.

    - 1990 XJ Laredo - Old and busted, but it'll get the job done!

    - 1996 XJ Sport - It's red. What else can I say?

    - 1997 XJ Country - My wife wanted something "pretty".

    - 1998 XJ Limited - Cheap and leathery.

      I was going to suggest the flap style like the TJ uses if it was too tall and if it would fit. I saw a direct replacement on Rock Auto for about eight dollars but that sounds kinda high just for a cap.

      Yep, that's what the 4.0L XJ uses...doesn't make any sense to be smaller, but I guess that's just the way it is!

      Turns out the one on Rockauto is only for the 4.0L and 2.1L diesel. It won't fit the 2.5L. Apparently, nobody makes the cap for the 2.5L anymore.

    Open Cooling System Conversion (Part 3)

    Success! After running into roadblock after roadblock searching for a coolant bottle cap, I started rummaging through my parts rigs. As I perused over my most recent aquisition (a wrecked '98 Limited), something in the mangled driver-side fender caught my eye.

    The washer reservoir in the '98 was gone, but the filler and cap were hanging there. I thought it looked like a close match, so I pulled the cap and went over to to check. Sure enough, the washer cap from the '98 XJ snapped right on the coolant bottle from the '87-90 XJ 2.5L.

    I'll probably grind down the raised letters on this cap, and add a coolant decal to finish it off. For now, it's 100% functional. While I was at it, I also replaced the old fan shroud. It was riveted together with sheetmetal, and while it was functional, it was damn ugly!

    I pulled the trigger today and ordered a custom decal for the cap. Details are everything!

      Rockhard 4×4 Bolt-In Roll Cage

      This was another impulse buy. I wasn't planning on a cage at this stage, but this popped up on Facebook, and it was priced at nearly half retail. Here's the disassembled cage being prepped for crating. I'll follow-up with more detail once it arrives.

        I thought it was a decent deal. There are a few design issues I don't care for, but I think it'll do what it's supposed to do. I'll probably have some extra beef added to the sandwich plates by tying them into frame stiffeners. Shouldn't be an issue to add those when the stiffeners are welded in.

        Open Cooling System Conversion (Part 4)

        The decals for my coolant bottle cap came in today. The finished product is OK, but certainly not as nice as an embossed cap. Not the most critical detail, but the last thing I need is someone dumping washer fluid in my coolant system!

          Tunes Upgrade

          I like to have a little noise in the cab when I'm driving, and the noise coming from the OEM speakers wasn't very pleasant. I found a couple sets of new (used) 5 1/4" Pioneer 2-way speakers on eBay for $18 bucks a set, and ordered some foam speaker baffles to install them in the factory location. It's not going to win any SPL competitions, but it'll work for what I need!

            Wagoneer Header Panel

            Tonight I picked up a complete header panel from an '87 XJ Wagoneer. These are pretty rare, so this will make for a truly unique look to my XJ. It needs some cleaning and a fresh coat of paint, but it's in great shape!

              Renix Engine Monitor (R.E.M. II) v. 5

              The Renix system is a pre-OBD engine management system developed by Renault and Bendix, and adopted by AMC for the early XJ's in the late 80's. It generally lacks many of the features found in post-'96 OBD2 engine management systems, and has historically required an expensive Snap-On diagnostic tool to access the data.

              Nick Risley of NickInTimeFilms is a fellow XJ enthusiast and Youtube content creator who created an affordable alternative to the pricey Snap-On tool. The R.E.M. II v.5 is the latest iteration of his invention, and provides Renix XJ owners a pretty slick live display of the Renix data streams in a compact package.

              I received my R.E.M. II last week, installed it, and configured a few simple settings. I now have live data from the various sensors in my XJ. This tool is an absolute must-have for any Renix-era XJ owner.

              If you've been keeping up with the thread, you'll remember that I've been fighting a low idle issue for the past year. As soon as I installed the R.E.M. II, I was able to finally solve that problem. As it turns out, the engine is idling perfect; the gauge simply reads too low!

                  It's been a great learning experience for me so far. In the past, I have deferred to friends with a ton of mechanical and fabrication experience. This time around, I'm diving in and trying to do everything myself.

                  I've always felt that I lack mechanical aptitude, but maybe my problem is lack of patience more-so than ability. When I do things, I try to do them right, but some of these things require more time than I'm willing to tolerate. My hope is that with the right tools and a comfortable shop to work in, I won't feel the need to rush things.
