What does anyone think about power steering fluid with stop leak in it? I used it with success on my Honda Accord (the pump was leaking). Am tempted to try it on my MB, which has a leaking hose.

Which hose is leaking?

The hose that's leaking is the one that's connected to the bottom of the psf reservoir. Probably needs to be replaced regardless.

If it's the one with a regular hose clap, just replace it. It's low pressure and any hydraulic shop should have suitable return tubing.

I wouldn't do it, because the stop leak is going to swell and harden every seal and rubber part in the ps system, including the gearbox.

As someone noted here.....it mainly works on your seals.....I doubt that it will fix a leaking hose......for that you need duct tape!!!!!
