.....never overheats now.
.....well, since it's usually 90+ degrees, and 100 percent humidity, here...I wanted my WJ to run a bit cooler than 210-230 degrees. I decided to do some preventative maintenence. I replaced the radiator, the fan clutch, the water pump, the thermostat, and added an auxilliary trans cooler. Oh, and some new shocks, and a tire rotation. In the process of removing the radiator, I discovered a very small pinhole leak at the very top of my core....that would explain the temp creeping up slowly while sitting idle, in traffic. Evidently it was leaking over time, and I saw no evidence of it....ever, and I looked. Anyway....I also discovered the old water pump had a plastic impeller....you know, the kind that like to disintegrate, then you wonder why you're overheating. The new one has a metal, high flow impeller....piece of mind is always a good thing. The old thermostat was the standard 195....but, I replaced it with a 180 since it's always hot down here, shouldn't give me any issues. I also ran the trans cooler in series with the radiator-trans to radiator, out of radiator to aux. cooler, out of aux. cooler, back to trans. So far, so good. She's running great, and can idle all day long, in this heat, and doesn't touch the 210 mark....just the line before it. I'm happy with the results, and she seems to be too. It was a long day....I'm gonna go chill....have a great night, guys.....Thomas
