Steve,

There is not much to the sensor itself.  I would look
all around before getting a new one. Can you see it
cracked and leaking or is it still comming from the
threaded portion of the tank/sensor?  If so tighten
the Sh**t out of it. I had to do this with a brand new
tank and brand new O-ring. It leaked until I tightened
it really snug. I think it is 32mm.  I used my
Campagnolo head spanner from my bicycle to doit.  Be
careful because the sensor is made of hard
nylon/plastic and will wear the edges of the nut if
the wrench slips off.

I would really put in a new water tank, only $19?
dollars with cap from the BusDepot.  This could be the
cause of the leakeage.  They do wear and crack with
the heat differential of the coolant.

Hope this helps
