    2003 Infiniti M45 - Fan Fluid Leak - Anyone Change To An Electric Fan???

    Hello,

    I was doing some maintenance under the hood of our 2003 Infiniti M45 when I noticed what appears to be the fuild (power steering fluid) leaking from where the top hose connects to the water pump for the fan fluid. From what I can find in pictures online, it looks like there's an O ring in there. I noticed the 2 bolts were a tad loose so I tighten them and so far it seems OK. Does anyone have a part number for the O ring, is it special or just a regular O ring? I was also wondering if anyone swapped out the factory fan for an electric fan and if so, how hard was it? Thanks.

    Good for now...

    It looks like the two bolts that attach the top hose to the water pump were about a half turn loose. The diagram in the service manual shows an o-ring in that connection. Seems OK now, but if it leaks again I'm going to remove the o-ring and replace it. It was definitely leaking at that connection.
