Excuse me for being daft, but what is a WIS and how do I download it?Download the WIS for your car. It has an excellent section on the hydraulic top operation and replacement of components. It does not support printing so it would take many screen captures to post each page individually. Start with either a google or isohunt search, then use a torrent downloader... Ron
Actually they discontinued the original fluid. Now the current Convertible fluid is CHF-11S. So either they want everybody's convertible to be destroyed, OR it CHF-11S is safe to use in the convertible... Im hoping for the latter because I had no choice but to top it off with CHF because they discontinued the original convertible fluid.Sorry, I disagree with the "use CHF-11S power steering fluid".
Don't do this, you'll find the cylinder seals leaking soon after. I know because I did this.
Saab only recommends Saab convertible top fluid, which is a special hydraulic fluid. It is thicker than CHF-11s.
People have used hydraulic pump oil and transmission fluid.
I used the saab fluid mixed with Haynes Hydraulic stop leak. I have since moved on to a mix of the haynes and hydraulic jack oil which seems to work well. Leaks are at a minimum and I'm satisified. The transmission fluid might be working for some because it has chemicals for the seals in transmissions. I chose to go with the Saab fluid and then the hydraulic jack oil, which looked to be pretty much the same.
Sorry if I offended you Keith. It's just that I had bad luck with the CHF-11s.
