Because silicone will NOT seal on surfaces contaminated with glycol, it
will just roll off. Learned that the hard way in Canada in the winter.
Use the red sticky liquid stuff. Coat the gasket and water pump,
stick it on, and the screw together. Won't leak through the gasket,
but you MUST
I used the red permatex spray. Sprayed the pump flange, the pump
housing, and both sides of the gasket. The spray seems easier to me
to get an even coat than the brush-on.
Hopefully it will hold up.

Hi,
Why not silicone?
I did an 82' 300sd 120k miles water pump replacement with a gasket
lightly coated
What about Hylomar? I've had good results with it.

Does permatex still sell it in FLAPS for $5 or so?
I found some on the net for something like $20 a tube.

Only too true -- my brother had a 75 300D break a crank (had some
bearing noise we didn't get to fast enough) caused by a hunk of
silicone from the oil filter housing bracket clog the main oil gallery

I don't have the book for the 617 engine, but:
Permatex - yes
Torque for 60x engines - 10NM or 7 ft. lb.
Anti-seize - Yes, hoping to prevent siezed then broken bolts next time
the water pump is replaced.

One thing I also did was use a tap to clean
Today there was a definite pool of coolant on the garage floor under
the front of the engine. Checked and there is a leak at the water
pump, can't quite tell if it's the shaft or the gasket that's leaking
but I guess since its age is unknown I ought to just replace it.

Why not pressure test the system with the engine warm? Some of the macparts
places may do it for free.
I slide a cardboard under and look for droppings.

You can borrow a radiator/cap pressure tester at Autozone. Just pay for
the thing and they refund your money when you return it.

Which reminds me -- did you fix that ignition thang (not a typo) of which
you sent me photos?
I laughed when I saw them, because I sold Debbie's Pontiac 6000 as a
screwdriver start car to a teenager -- he thought it was cool. The
ignition switch failed w/ a key but worked great w/ screwdriver.

Replace your radiator cap.
A bad one allows coolant to boil out when the engine is stopped hot.
Also check for a leaking upper radiator hose, especially the hose
nipple on the radiator, as they get brittle and crack. Will only leak
intermittantly.
Also, if there is ANY coolant in the weep
