I checked it out by grovelling around underneath the vehicle today.
The replacement pump they sell is an impeller and seal unit that bolts
between the pully and housing which is, in turn, bolted to the engine.
That housing is what the pipe bolts into. There is not much room, so
it appears you need to pry the engine a bit to give a tad more access
to replace it.
But the good news is (at least for this issue) that the pump was not
leaking. Bozo here, who is very far from a master mechanic, did not
know of the trick to use grease on the parts to ensure that the big O-
ring does not roll and bind or slip off the pipe unit.
I yanked it apart and found the O-ring had been mashed out of place
and not sealing properly. I looked everywhere, since the dealers parts
counters were closed and could not find a replacement, so I reformed
the mashed one and greased it all up properly and wiggled and pushed
it until all of a sudden it just sort of went POP and seated. I bolted
it up and - no leaks!
I am sure everyone except yours truly knew about the grease (not just
any kind since some will attack the rubber) but that is what fixed my
issue.
Thanks for taking the time to reply - appreciated.
Funny - the first time takes twice as long as the second time....
anyone notice!? lol.
