Replacement Power steering fluid?
Aloha, Dave
As I have to remove my power steering reservoir and steering rack everytime my motor is out, which it is right now for pre-Runoffs rebuild and blueprint, I have had to replace my power steering fluid several times.
I have been using Havoline power steering fluid for about a year now with no problems. I bought it because it was easy to find at most auto parts stores.
Havoline meets GM spec 9985010, but I'm not sure if this is the correct spec for the C5/Z06 and I don't have my service manual or owners manual to check it. Sorry.

I know what you mean. The part numers came out of the service manual.
Also here is some more non information:

and Castrol:

and Redline says they meet the spec:

Assuming they are correct, that would mean all of the above mentioned fluids are okay.
Dave,
You're welcome. Hope your are enjoying the weather out in Hawaii. I spent four years there in the late 90s and hope to make it back.
