Once I got all the parts, putting the new water pump on and everything
back together was not too bad.
I did get a tube of Hylomar Advanced Formula and used that on the o-ring
sealed plate that goes over a machining hole on the back of the pump and
on the o-ring sealed connection between the pump and the block. The
o-ring for the plate fit tightly on the o-ring groove, so the Hylomar AF
wasn't necessary there. The o-ring for the pump to block connection,
however, was loose in its groove, so the Hylomar was quite necessary
there to keep the o-ring correctly positioned during assembly.
Before I took things apart, I was aware that a bearing was making noise.
I felt the bearing for the serpentine belt tensioner pulley and found
roughness, so I got a new one of those.
I'm not sure how thoroughly I checked the fan shaft bearing, but when I
put the fan pulley back on, I spun it by hand and heard bearing noise.
Oops. I guess I will be taking things apart again in the not too distant
future. At least this time, the heater water return pipe bolt won't be a
problem and I'll know what I'm doing.
I just have to find out from Rusty whether the bearing is available
separately, or if the bearing support plate has to be replaced (which is
definitely the easier, but more expensive, way).
