Power steering cooler leak

Rube · 05-02-2018, 11:24 PM

Hey everyone,

While under my 07 335i I noticed power steering fluid sweating from where the lines connect to the power steering cooler. Is it possible to replace the o rings in those lines or am I stuck buying new lines? Has anyone replaced just the o rings ? Tried searching couldn’t really find any info if anyone has done it that way

Thanks

The whole thing leaks a bit for mine also. I think it's common for it to leak from the top but if it leaks from the bottom, some people just replace the tubes or reservoir itself.

Thanks for the reply. I meant my leaking/sweating fluid is coming from where the lines connect to the power steering cooler, which is located on top of the intercooler. Both lines can be seen just below the upper radiator hose on driver side. There’s o rings in those fittings just wondering if anyone was able to replace the o rings rather than the lines.
