The other day, when my buddy who's a commercial AC guy is helping me
search for an AC leak, he comments on the strange growl coming from
the engine.  I hadn't heard it until that day either.  But lately, I
had been smelling coolant and figuring, oh boy, head gasket job coming
up.  But then last night, when I smelled it, I looked under to see if
I could see the leak.  Well it's dripping a good bit from the water
pump.  AC's going to wait.

Checked the Bentley in preparation, I can't find anything about the
R&R procedure for a water pump, just a picture of it in an exploded
diagram of the cooling system.  Now I remember when I did the exhaust
on my 89, that it's pretty tight in there.  So I checked the archives.
Best I came up with was talk of it being a 4 hour job.  Good, that
tells me that the engine can stay in.  But though I can see which
bolts must be undone, I wonder if there's any order parts should be
removed to make the job easier.  Or parts that need to come off for
those other parts to come off ?

Also, I wonder if the intermittent growl could mean that it's grinding
on the block.  I remember some posts about the water pump eating into
the block and having to fix it with JB Weld.  If the gauges are small,
does it still need JB Weld ?
