GM / General Motors: 2000 silverado leaking coolant

Is it possible it's coming from the radiator cap? There is a bulletin about
coolant loss from a bad sealing surface on the radiator filler neck, it
advises polishing with 400-grit sandpaper backed with a block of wood.

There are no bulletins that I'm aware of for premature pump or head
gasket failure. There should be on the head gaskets, but that's another
story. The three items I've seen fail on these engines are: water pump,
water pump gaskets, and head gaskets. The head gaskets just split
along the outer edges and leak coolant, usually though...the leak
will run back along the parting line (head and block) and appear
to come from the rear. Replacing the water pump is fairly straight
forward, and probably quite expensive, as the pump comes complete
with the pulley pressed on, and new thermostat and housing. That's
a GM one, but I'm not sure if they have reman or aftermarket one's
available yet.

You mean to say the Thermo housing is part of the water pump? Is that on
the 5300 V8?

If you just had the 35,000 mile service, maybe you got the pin hole in
the radiator hose trick performed by some good wrench ?
