Is the power steerring pump reservior supposed to have pressure in it? After driving for awhile and the fluid is warm/hot and I remove the cap there is pressure behind it, not alot but some. I see there is a spring on the cap against the rubber cap seal. Is the spring supposed to release pressure like a radiator cap, or is it simply to hold the cap tight?
I'm beginning to see seepage around the seams in the reservoir, nothing major but wondering if the pressure build up is supposed to happen and if not, is the pressure causing the seepage problem.
From the 2000 Service manual : 10) Gauge should read below 862 kPa (125 psi), if above, inspect the hoses for restrictions and repair as necessary. The initial pressure reading should be in the range of 345-552 kPa (50-80 psi). I noticed that my pump reservoir was pressurizing also. Unfortunately, mine started making all sorts of noise during the latest cold spell. I anticipate having to change out the pump come this Monday. Anyway, at 125 psi or even at the 50 - 60 psi, I'm not surprised that with a sealed cap that there is quite a bit of pressure on the reservoir cap.

There is also threads on how to put a ZJ or WJ power steering pump in a XJ. It might even be a direct swap. I was thinking about doing this maybe the next time that I swap mine. Supposed to get a lot more fluid and makes it easier on the pump because it was designed for the V8.
I could not find them for some reason and don't have more time to look for it. Hopefully you can find it if you want it. Or maybe someone else on here knows of a link.

I'm not experiencing any problems with the power steering pump, so not planning on replacing it right now. I was just curious as to if there was supposed to be any pressure buildup in the reservoir itself. From what you guys have posted up here it appears the pressure is normal.
I did siphon out the old fluid the other day, it looked like mud. I refilled it and ran it for a day and siphoned it out again and refilled it. The fluid looks pretty good now. I might do it again come spring.
Love that plastic pulley on the metal hub ! Not really, it was a PITA ! The metal pulley hub is so cheap that it pulled the lip right off the pulley. And that was with using a pulley puller. The low pressure hose nib also broke off during removal. So I ended up replacing the pump, pulley, and reservoir. That's the price you pay for cheap Chinese parts. The good part was that the whole thing cost under $100. Well at least the steering doesn't groan any more.

Most places (at least Napa by my house) will pull the pulley and put the new one on for you. I did the same thing my first time, bought a sweet puller and got the whole thing set up and couldn't get the new on back on without breaking it...
Now I have done it a few more times and it takes like 5 mins to let them get it. Well worth the extra money that you pay at Napa.

x2... also if you have a good relationship with the parts guy they'll let you poke around parts books and see what parts swap over to what.
Ever know that early S10 front suspension is the same as Monte Carlo/Regal from the 1980s? Dunno abou thte 'rounded' s10 front suspension... might still be the same.
