1997 43.L Chevy 350 6 cylinder. Freshwater. Manifolds and risers are
original.

Tuned up just weeks ago with only 4.2 hours on the engine following the
tune-up.

Thermostat was replaced in spring.



I wonder if your tune-up guys pooched something and didn't tell you.
Not likely. More likely a scenario like this: Plastic bag gets sucked up
against water intake. Water is restricted or cut off completely. Engine
overheats and water pump fries. Engine shuts down or is shut down and
plastic bag slips away. After inspecting the water pump, mechanic suggests
that the owner ran the engine without water. Owner suggests to mechanic that
he should have seen that the water pump was on it's last legs when he
inspected it. (Write your own ending to this story)
