Back to the power steering pump swap. I've been driving the Explorer for the past few weeks. Highways, interstates, graded dirt, forest roads, technical rocky off road trails, etc. Pretty much every type of terrain. It was definitely worth the time and money. It's a obvious and subtle difference.
Obvious because I haven't found a surface where I can't steer those 35" Maxxis Razrs. Can even turn the wheel with the front elocker on, and both tires on rocks. And, completely silent.
Subtle because it's smoother in every way. Little more feedback through the wheel. Takes a little more effort on loose surface turns and cruising down the highway, and a lot less effort on hard surface turns. Works very well with tight steering gear boxes, like my Redhead. The way the reservoir is designed, there is plenty of head space to keep the fluid from contacting the cap even at extreme angles, so no more fluid loss through the cap.
In a previous post, I mentioned a smell when the fluid gets hot. The smell was actually synthetic brake fluid that had leaked out of the reservoir because I overfilled it. This pump seems to run hotter than the OEM, or get hotter faster, but there is no frothing or loss in power.
Related, but difference subject: My transmission cooler lines bypass the radiator, so the radiator trans fluid cooler is empty. I was tossing around the idea of using that for the power steering. I need to find out how the PS operating temp. range and see if it's compatible with the engine. Since I installed an all aluminum 3 core radiator, the engine hardly ever gets above the "O" in NORMAL and then only if I am running the AC. Not sure I want to jeopardize that, because I like the low temps. It would add almost a quart of PS steering fluid. I kept the tube and fittings when I bypassed the trans cooler lines so it would be a fairly easy job.
Currently, all of my systems are separate. Not sure I want to compromise that either. I might be making a issue where there is none, since the PS pump doesn't seem to get all that hot and I already have a in-line cooler and filter that add about a quart.
I just about have myself talked out of doing this.
So, is there anything I could do with that empty cooler space?
