H6 power steering issue

One, why did you change the chain? Unless there is an oiling issue which would cause internal engine damage those chains don't wear out.

What kind of fluid did you put in? Do you have a "kinked" hose?

And just for future reference, you don't need to disconnect PS hoses, just unbolt the pump and move it over to the fender.

I had to do the guides and tensioners 8)

no kink on the lines or hoses but as I was reading last night, the problem may be with the hardened hose from reservoir to pump and the o ring thing too

so I'm changing those today

on the H6 engine 01 - 04, it is most likely the o-ring on the intake suction hose on top of the pump. they get old and brittle and suck air causing a whine. easy to fix, one bolt, 15 minutes, and about $1.50 from the dealer. you can probably match it up at the local parts or hardware store for less.

do you have bubbles or foam in you reservoir?? this is an indicator of a bad o-ring.

i think the part number for my o-ring is 34427AA060. i know that is the part number for an o-ring for something, i saved the package. i just can't remember if it is the steering pump o-ring. sorry.



on the h4 engines 00 - 04, if you over tighten the ''belt guard'' on the alt, steering pump and AC compressor, you can ''flex'' the steering pump and this will cause whining. and i have heard of one case where it was left un-repaired and actually wore the pump bearing. but usually if addressed quickly, loosen all the ''belt guard'' bolts and then snug them up correctly it eliminates the issue.

yeah, it's just the air problem on the suction side. Change the o-ring, consider putting better hose clamps on that hose from the tank. Don't over torque the bolt holding the hose mount on top of the pump.

It will bleed itself fairly quickly. Use a turkey baster with a length of hose on it to swap out some of the fluid if it's dark. Use Dexron III or equivalent. NOT some generic PS fluid.

according to opposed forces its 34439AE020
