We had a big weekend of Jeep repairs. Put a new steering box in mine, fixed the flat left front (again/for reals this time),
flushed Cyd's heater core, and set out to fix the power steering issues in Cyd's Jeep once and for all.
Both TJs are locked on both ends, but since the tires are relatively small, neither has ever been in a position where it felt like they'd really benefit from a ram. Mine's actually all set up for one, but we've just never seen the need. However, Cyd's TJ has a Spartan in the front, and the PS fluid will get hot. The problem is usually caused by long stretches of trail with lots of turns. Pretty soon, the power steering pump is howling like a cat in heat.
A couple of weeks ago, I stumbled across this:
The PSC MBC100K power steering cooler kit for Jeep TJs. For a bit over $100, you get a bolt-in cooler bracket, a $50 Derale cooler, and enough 5/16" low pressure line to last you the rest of your life (aka, about 10ft worth).
I liked at least two things about this: I prefer for coolers to have some sort of bracket holding them to the vehicle (no zip ties through the radiator for me). Also, I'm lazy, and this came ready to bolt in. No need to waste my Sunday afternoon trying to fab up a crappy little bracket out of pieces of steel strapping.
So, step one: Do as little work as possible. I removed the fan and fan shroud, unbolted the radiator and AC condenser and pushed them far enough out of the way to work.
Step two: bolt the cooler to the bracket
Step three: Remove the V brace from inside the grille. The cooler support bracket takes its place.
Step four: figure out where the PS lines will run. I drilled two holes with a 1" spade bit through the plastic air dam on the driver's side of the radiator.
Step five: put it all back together, bleed the system.
The more observant of you may have noticed that the kit includes an option for a second cooler. Might be nice for those with automatic transmissions.
Total install time was two or three hours, taking my sweet ass time.
Lastly, if your TJ doesn't have AC, the install might be a bit simpler. You might be able to slip the pieces through the gap in front of the radiator, leaving the radiator unbolted, or maybe just pushing it back a few inches without removing the fan and shroud.
