When Jess pull up in the drive way I noticed that sweet smell of hot antifreeze. When I popped the hood I saw the problem. The top of the plastic end, had a hair line crack and was pissing out antifreeze. The crack is small enough that when the system was no longer pressurized I had to look really hard to even see the crack.
I managed to get a replacement radiator from autozone, and a lower hose from advance, but I have to wait 2 days for the upper hose. To swap the radiator out, was a PITA. The KJ has A/C, a transmission cooler and a power steering cooler, all of which had to me moved or removed. The grill and the grill support also had to come out, as well as the electric fan. A lot of bolts, but that's what air tools are for. The hardest part was getting the new lower hose back on, there isn't a lot of room for the spring clamps. When the new upper hose gets here, I'll swap it on, but for now it is fixed.
I also changed the spark plugs with the Autolite Double Platinum's that all the guys on the Lost KJ's sight recommend. The ones that were in there had been these since 45-50K miles and now it has 120K so they had been in there for a while. The Autolite's that were in there showed very little wear, and only one didn't have the recommended gap. I also cleaned the intake and now it has the get up and go like it was new.
