Sure, but tomorrow as it's night now over here.
Basically, there's the steering box where it's supposed to be down by the frame, and then a metal line in a rubber sleeve is directed into the engine block, just below the A/C compressor (which is where my Haynes manual says the steering fluid reservoir should be), and then another steel line in rubber returns to the steering box. The metal lines screw into the steering box and into the engine block. There are no other hoses connected to the steering box, and there sure isn't any reservoir anywhere. Or maybe it's tucked into the engine so tight I can't see it - maybe close to the steering pump? Perhaps the metal lines connect straight to the power steering pump?
It's clear the A/C system has been replaced somewhat recently, possibly to make use of the newer enviro-friendly gas, and the A/C compressor sits atop a large metal bracket on the top left of the engine. I wonder if to fit it some creative mechanic decided to remove the steering fluid reservoir...
The metal lines connecting the steering box with the engine block also appear to be new-ish.
The power steering works fine, no troubles there.
Tomorrow I'll take photos and check if it's behind and under the A/C compressor, I mean, I can't see how it would work otherwise.
You'll forgive me for talking out loud here, but I live on the edge of a friggin' desert in the Middle East and it sure looks like I own the only K5 for a few hundred miles around, maybe thousands?
